1 INTRODUCTION

This document provides the link administrator with useful information regardingconfiguration and management of a SRA L link, i.e. a system based on TCP/IP protocol,normally used in Internet an Intraned network type.The following are detailed descriptions of:

– the main addressing and routing characteristics of TCP/IP networks

– the main characteristics of the TCP/IP protocol used in SRA L link and of thededicated software for the link administrator

– the main characteristics of the connection to a TMN supervision system

– the guidelines for the planning and configuration of a SRA L link.

For general concepts and detailed information regarding the protocol and TCP/IPnetworks please refer to specific documentation in par. 13 ("Bibliography").



2 ADDRESS FORMAT FOR TCP/IP PROTOCOL

2.1 Host and router

Network devices for the TCP/IP protocol are subdivided into:

– Host: device for an application that responds to the TCP/IP protocol

– Router (or gateway): device that manages routing information for various networklines.

The SRA L is a device that can function both as a host and a router.

2.2 IP address classification

The TCP/IP networks use a 32-bit (4 bytes) address to identify the host, the sub-networkand the network to which the host is connected.The IP address is not limited to just identifying a host as such, but it also identifies theconnection of a host to the sub-network and to the network. Therefore, if a device ismoved to another sub-network or network, its IP address must be changed accordingly.IP addresses are classified on the basis of their format. Generally the following addressClasses are used (Fig. 1):

– Class AA Class A address has the following structure:• the first bit of the first byte = 0• the remaining seven bits of the first byte identify the network• the last three bytes (24 bits) identify the sub-network+host field.Class A addresses are used for networks with a large number of hosts. Thesub-network+host field is a 24-field and therefore 224 hosts can be detected.The number of networks addressable by Class A addresses is limited.

– Class BA Class B address has the following structure:• the first two bits of the first byte = 10• the remaining six bits of the first byte plus the second byte (14 bits) identify

the network• the last two bytes (16 bits) identify the sub-network+host field.Class B addresses are most widely used because they allow a compromisebetween the network number and the sub-network and host number.

– Class CA Class C address has the following structure:• the first three bits of the first byte = 110• the remaining five bits of the first byte plus the second and the bytes (21 bits)

identify the network• the last byte (8 bits) identify the sub-network+host field.Class C addresses are used only for networks with a limited number ofsub-networks and hosts.



There are also Class D and Class E addresses but their use is not provided for in theSRA L link.In the case of the SRA L link, the host field identifies the SRA L equipment and thesub-network field identifies the station; the network field can be set to any value.

Fig. 1 – Structure of IP addresses

2.3 Decimal notation of the IP address

The IP addresses are usually written in decimal notation, which is to say they are writtenby means of the corresponding decimal value of each of the four bytes composing theIP address.For example, the following Class B IP address:

10000000 00000011 00001001 00000001is written as:

128.3.9.1and is translated into the network ID 128.3 and into the host ID (sub-network+host) 9.1.In decimal notation, the value of the first byte allows the immediate identification of theClass to which the address belongs:

– Class A address: initial value in the range 0 to 127

– Class B address: initial value in the range 128 to 191

– Class C address: initial value in the range 192 to 223.

For the SRA L link, it is advisable to use Class B addresses.The limit values of each field with all "0" and all "1" must not be used becausethey are reserved addresses (see par. 2.5).To reduce the possibility to have malfunctioning TCP/IP configuration, thesoftware (Link Viewer program) is provided with not assignable values for the IPaddresses (see par. 10).

i



Tab. 1 summarizes the main characteristics of several IP address classes.

Tab. 1 – Characteristics of IP addresses

* Some address values are reserved and cannot be used (refer to paragraph"Reserved address values").

2.4 Net-Mask

The final field of the IP address consists of two sub-fields: the first one identifies thesub-network while the second one identifies the host.In TCP/IP networks a mask, known as Net-Mask has to be specified for each address.This mask is always composed of four bytes and it is subdivided into two parts (Net-Partand Host-Part). It serves to indicate the configuration of the different fields of the IPaddress and specifically the configuration of the sub-network+host field.The number of bits for each sub-field is variable and can be different from address toaddress. However the sum of the two sub-fields must be equal to the sub-network+hostfield.The Net-Mask allows correct understanding of the IP addresses because it shows howmany bits are used to address the sub-network and how many to address the host.The method used to determine the Net-Mask consists of starting from the IP addressand encoding, into the Net-Part, the bits relating to the network with all "1" and, into theHost-Part, the bits relating to the sub-network with all "1" and the bits relating to the hostwith all "0".Cross combinations of the bits relating to the sub-network and to the host (Host-Part)are possible, but their use is not advisable owing to the subsequent difficulty innumbering and reading.Figure 2 shows some Net-Mask examples for the Class B address:

– 255.255.255.0 8 bits to address the sub-network, 8 bits to address the host

– 255.255.252.0 6 bits to address the sub-network, 10 bits to address the host

– 255.255.255.192 10 bits to address the sub-network, 6 bits to address the host.

In the Net-Mask, the bytes relating to the network (Net-Part) are always equal to 255.

Fig. 2 – Example of Net-Mask for Class B IP address

2.5 Reserved address values

The IP address can be coded by filling fields with a complete set of "1".Such a coding operation defines a multiple transmission signal (broadcast):

– all "1s" in the network field: transmission to all networks

– all "1s" in the host+sub-network field: transmission to all hosts of the network

– all "1s" in the host field: transmission to all hosts of the sub-network.

For example, the IP address = 128.2.255.255 identifies all hosts in the 128.2 network.The IP address can also be encoded filling the various fields with a complete series of"0", identifying in such a way the address as "this network", "this sub-network".For example:

– the IP address = 128.2.0.0 identifies the current network, namely 128.2

– the IP address = 128.2.30.0 (with Net-Mask = 255.255.255.0) identifies the currentsub-network, namely 128.2.30.

The possibility of inserting "all 0" in the network field is useful, for example, if a host doesnot know its own IP address. In such a case, the host will transmit an address with only"0" in the network field and the other hosts will acquire this address as the indication ofthe subject network.IP addresses corresponding to fields with "all 1" or with "all 0" are therefore reservedaddresses.Therefore the limit values of every field with "all 0" and with "all 1" must not be used asnetwork, sub-network and host addresses.Tab. 2 shows which addresses are reserved and which addresses are available if theTCP/IP network has been inserted into an Internet context.

3 SRA L LINK

3.1 SRA L link structure

The SRA L link is a TCP/IP system constisting of the following elements:

– SRA L: with function (host and router)

– PC: host function

– router for third parties.

Usually a SRA L link contains a couple of SRA L of tWo front-end stations (see Fig. 3).If it is present a SRA L in Add/Drop configuration, the SRA L link contains three SRA Lsof three different stations. In such a case, the terminal SRA Ls are placed at the twoopposite ends and the Add/Drop repeater SRA L is placed in intermediate position (seeFig. 4).It is possible to insert every where into the SRA L link a router of third parties. Theconnection of a router is executed by means of the interface normally used for the PCof a SRA L and called F interface.The SRA Ls into the same station but belonging to different links can be interconnectedby means of the V bus.The SRA L link allows the link administrator to utilize the Element Manager function forcontrol and configuration of all SRA L operating parameters.The SRA L link has been preset for interconnection with a TMN supervision system withOSI or QD2 protocol. Such a system allows to make use of the Network Managerfunction. The physical connection requires an optional SRA L unit (Q-Adapter unit). Itallows to adapt the OSI or QD2 protocol layers to the TCP/IP protocol layers andvice-versa.

It’s possible to create mixed links, composed by SRA L of different type (linkwith one Full ODU SRA L and one 8x2 Mbit/s SRA L), because they arecompatible at RF level.

3.2 Routing functions of the SRA L

Every SRA L is a device with dual function: the host and the router. This feature ispossible because the SRA L is able to identify the destination (the SRA L itself, anotherSRA L, a router, a PC) on the basis of the IP address and consequently to route themessage towards the proper path.As a router, the SRA L is capable of branching the signal over different routes:

– toward its own circuits; in this case the SRA L behaves a host

– toward a local PC or router, through serial line (F interface)

– toward a SRA L of the same station, through LAN (V bus)

– toward a SRA L of another station, through radio (R and D channels).

SRA Ls of the same station can be interconnected by means of a LAN.The LAN is physically implemented by means a two-wire V bus (half-duplex) with adaisy-chain structure.Up to a maximum of 32 SRA Ls can be interconnect through a LAN .Each SRA L has a preconfigured local IP address (the same for all systems) whichallows a local connection through which the operator may assign the IP address.Fig. 5 shows an example for the routing strategy in a SRA L link. Fig. 6 shows the routingarchitecture diagram of the SRA L.

3.3 Routing tables

In a TCP/IP network, element with router function manages the routing according torouting tables which specify the parameters for every possible route. The routing tablescan be of two different types:

– Static routing tables: These tables are defined by the network administrator and arefixed in advance. In case of network expansion or change they have to be updated.

– Dynamic routing tables: These tables are generated by the various networkelements with router function on the basis of to the information acquired by thenetwork. In case of network expansion or change these tables are automaticallyupdated by means of a routing protocol.

For this purpose the SRA L supports the RIP protocol version 1. Consequently, everySRA L is able, depending on information acquired from the link, to obtain a completeoverview of the link structure. Dynamic routing tables are created automatically,enabling the SRA L to define a routing over the most suitable path.In the presence of expansion, change or failure/interruption of the SRA L link, eachSRA L automatically updates the corresponding dynamic routing tables, thus adaptingthe tables to the new SRA L link structure.

Static routing tables are required if routers not supporting the RIP protocol are usedinside the SRA L link.A specific routing table can be created to exit from the SRA L link, which via the RIPprotocol is recognized by all SRA Ls as the default outlet of the SRA L link.

3.4 Host table

The creation and use of a host table on the service PC, allows to associate a mnemonicacronym with each SRA L which can be used instead of the numeric IP address.In the host table, the correspondence between mnemonic acronyms and numeric IPaddresses must be specified for all hosts in the link.The host table can be dynamically defined by means of DNS, if a device with thisfunction is connected to the SRA L link.The procedure for creation of the host table is described in the document "Installation oflink software".

☞ The RIP protocol version 1 re quires the same Net-Mask in the entire the SRA Llink.



3.5 SRA L communication channels

Several communication channels are used in SRA L, for the transmission of SRA L linkmanagement and supervision information:

– Integrated channel R1/R2The integrated R channel is a 64 kbit/s synchronous data channel with TCP/IPprotocol.It is a reserved channel in the radio frame and is used for the transmission ofmanagement information between two SRA Ls of two different stations via radio.In case of SRA L with 2x(1+0) and A/D-RPT configuration, there are two differentintegrated channels (R1 and R2).In case of SRA L with (1+1) configuration, the two channels R1 and R2 are used inprotected mode; the redundancy is managed by SRA L hardware.

– PC channel (F interface)The PC channel is a 19.2 kbit/s asynchronous data channel (RS-232C standard).It is used for transmission of management information between the SRA L and aPC or a router through a serial line.The connection with the PC channel can be realized by means of a modem.

– V busThe V bus is a 128 kbit/s data bus with burst mode (HDLC frame) and TCP/IPprotocol.It is used for the transmission of management information between SRA Ls of thesame station.

– Q channelThe Q channel is used for the transmission of management information betweenthe SRA L and a TMN supervision system.The Q channel is available with two different protocols, depending on the type ofsupervision system:• QD2: connection to Access Integrator or other QD2 managers• Ethernet (10BASE2): connection to EM-OS with standard OSI protocol.The Q channel is present if the SRA L is equipped with the Q-Adapter unit.

– D1/D2 channelThe D channel is a 64 kbit/s synchronous data channel with TCP/IP protocol. It isa reserved channel of the radio frame and it is used for the transmission of the TMNsupervision information on one slot of the 2 Mbit/s tributary stream (slot andtributary are programmable).In such a way the supervision information can cross different transmission systems(e.g.: optical fibre systems) and reach other SRA L links/networks.In case of SRA L in 2x(1+0) and A/D-RPT configuration, there are two independentD1 and D2 channels. In case of SRA L in (1+1) configuration, the two channels areused with protected mode and the SRA L hardware manages the redundancy.In case of equipment provided with V&D Channel Distributor unit, the D1 and D2channels are available at connector, for the possible connection towards othertransmission systems; in such a way the supervision information (TCP/IP) canreach SRA L links/networks.

Fig. 7 shows the communication channels available in the SRA L.

5 TCP/IP PROTOCOL OF THE SERVICE PC

For the SRA L link connection, the service PC must be equipped with a TCP/IP protocol.Installation and configuration of the TCP/IP protocol differ depending on the softwareused:

– under Windows 3.1/3.11 the TCP/IP protocol provided by the SuperTCP stack isused. Only PPP or SLIP connections are provided

– under Windows 95/NT the used TCP/IP protocol is provided by the operatingsystem itself. It is available either with serial RS-232C or Ethernet interface. If theserial interface is used, it is necessary to install the direct connection mode with aspecific driver provided on CD-ROM.

The TCP/IP protocol, either in Windows 95/NT or in Windows 3.1/3.11, provides the linkadministrator with some utilities for the control of the link features.The utilities of the SuperTCP program can optionally also be installed in Windows 95/NT.If the PC is used for the download of the unit software (Controller and/or Q-Adapter) bymeans of FTP, it is necessary to install the SuperTCP program in Windows 95/NT.For more detailed information about the installation and the configuration of the TCP/IPprotocol please refer to the document "Installation of link software".Tab. 3 resumes the TCP/IP characteristics according to the used software.

Tab. 3 – TCP/IP protocol of the service PC

Windows 3.1/3.11 Windows 95/NT

RS-232C serial Available with PPP or SLIP protocol; requires installation of the SuperTCP program

Available with PPP protocol from the operating system; requires installation of the driver provided on CD-ROM

Ethernet Not available Available from the operating system



6 LINK MANAGEMENT SOFTWARE

The SRA L link management software provided for the link administrator consists of twoapplication programs for Windows which are available on CD-ROM:

– Link Viewer programThis program allows to configure the SRA L link and to manage control andconfiguration of all SRA Ls in the network. For SRA L link configuration, theprogram allows the configuration of parameters TCP/IP and static tables for everySRA L. If a TMN system with OSI/QD2 protocol is connected, the program alsoallows to configure the TMN connection parameters for SRA L which act as a

gateway. This program is intended for normal operators.

– Net Builder programThis program allows to create the link map. These maps constitute the graphicalinterface of the Link Viewer program for connection to the SRA L. This program isintended for link administrators.

The programs are available both for Windows 3.1/3.11 and Windows 95/NT.For more detailed information regarding the operating modes of the programs pleaserefer to the documents "Guide to use of Link Viewer program" and "Guide to use of NetBuilder program".

For every Kind of SRA L, a specific plug-in software is provided, which makesthe equipment control and configuration possible, using Link Viewer.i



7 AUXILIARY UTILITIES

The link administrator can use the software utilities of the TCP/IP protocol to check theSRA L link features.The TCP/IP protocol of the Windows 95/NT operating system makes the followingutilities available as DOS commands:

– PingIt is possible to send a ping command towards a host in order to verify if the TCP/IP stack of the addressed host is visible and to measure the transmission time inthe go and return direction.

– NetStatThis is a typical Windows 95/NT utility which allows to call statistics all active TCP/IP connections.

– TraceRTIt is possible to send a TraceRT command towards a host in order to verify if thepath to reach the addressed host is the intended path and is free from failures and/or conflicts.

– RouteIt allows managing the local TCP/IP routing table (route). In particular, the "PRINT"option allows the displaying of the entire routing table.

– Ipconfig (only for Windows NT)It allows checking the configuration of the PC interfaces that use the TCP/IPprotocol.

In Windows 95, the Winipcfg utility with graphical mode is available: it has the samefunctions of the Ipconfig utility used in Windows NT.The optional TelNet utility with graphical mode is available in Windows 95/NT. Such autility allows opening a virtual terminal in the TCP/IP stack of the specified host.Similar software utilities with graphical mode are provided in Windows 3.1/3.11 by theSuperTCP program.If the operator wants to work with graphical mode utilities instead of DOS commandmodes, the utilities of the SuperTCP program can also be installed in Windows 95/NT.The SuperTCP program, then, makes available as in Windows 3.1/3.11 as in Windows95/NT the FTP Client and FTP Server utilities.Such utilities allow the download procedure from remote of the software of the Controllerunits (FTP Client) and of the Q-Adapter units (FTP server).



8 CONNECTION WITH A TMN SUPERVISIONSYSTEM

The connection feature between SRA L link and TMN supervision system (EM-OS) isrealised by the Q-Adapter unit. Such a unit provides the translation between TCP/IPprotocol (SRA L link) and standard Qx/Q3 protocol (TMN supervision system).A number of different configurations are possible (refer to Fig. 10):

– Configuration 1: Q-Adapter unit connected directly to the supervision system

– Configuration 2: Q-Adapter connected to the supervision system through the SDHnetwork.

An Ethernet (ISO 8802.3) interface is used, to connect Q-Adapter unit to EM-OS .As an alternative, the Q-Adapter unit allows connection of the SRA L link to the AccessIntegrator supervision system or other QD2 managers by means of the QD2 interface.The Q-Adapter unit is connected to the controller of the same SRA L and to thecontrollers of other SRA Ls in the station through the V bus (refer to Fig. 11).Full ODU SRA L is not equipped with the Q-Adapter unit. However, a Full ODU SRA Lcan be supervisioned by a TMN system, using the Q-Adapter unit of another SRA L forthe connection (8x2 Mbit/s SRA L or 16x2 Mbit/s SRA L) The following cases arepossible:

– mixed link, the last one is equipped with the Q-Adapter unit

– connection between a Full ODU STA L to another SRA L in the station, via V bus.The second SRA L is equipped with the Q-Adapter unit.

Fig. 12 shows the stack of the standard Qx/Q3 protocol.



• The SRA L link can therefore be connected to the supervision systems EM-OS orAccess Integrator.

9 PLANNING AND CONFIGURATION OF ASRA L LINK

9.1 Planning of IP addresses

For the assignment of IP addresses for the SRA L link, the link administrator has toproceed as follows.

1. Choose the IP address type to be used for the SRA L link:• Class A• Class B• Class C.If Class A is selected, please note that the last 2 bytes of the IP address of all theSRA L systems on a single V bus must be different, because they are used as MACaddresses (see Fig. 8) on the same bus.

2. Assign the network ID of the IP address. During the assignment of the network ID,pay attention to the current SRA L link type.• stand-alone type SRA L link: it is possible to use any network ID.• Intranet type SRA L link: it is necessary to use a network ID that has not been

yet assigned, otherwise, there will be conflicts and routing failures betweenthe interconnected networks.

• Internet type SRA L link: it is necessary to request the IP address assignmentfrom the authorised entity (IANA).

3. Assign the Net-Mask; it must be unique for all the SRA L link to define how manybits, of the sub-network + host of the IP addresses field, have to be used for thesub-network addressing (station) and hor many for the host addressing (SRA L orservice PC).

4. Identify every station with its relevant IP address, assigning the sub-network ID ofthe IP addresses.

5. Identify every SRA L with its relevant IP address, assigning the host ID of the IPaddress, follow the rules listed below:

• Addresses with fields coded with "all-1" and "all-0", must not be used for asingle link element because they are reserved addresses of a TCP/IPnetwork.

• Every station LAN can contain up to a maximum of 32 SRA Ls and hence canseize up to 64 different IP addresses (32 IP addresses for the SRA L + 32 IPaddresses for the corresponding F interface).

• With Q-Adapter unit equipped, it is necessary to assign an IP address also tothe V interface of the unit itself.

The TCP/IP parameter validity conditions (see par. 10), of the software (LinkViewer program), has to be considered when the configuration and planning ofthe SRA L link has to be carried out.

For the SRA L link, it is advisable to use Class B addresses.

i

i



6. Define the static routing tables.Static routing tables are strictly required for SRA Ls connected to routers notsupporting the RIP protocol.The information contained in the static routing table of a specific SRA L can beacquired via RIP protocol, also from all other SRA Ls in the link.

7. Define, if desired, the host table in such a manner as to associate a mnemonicacronym with every IP address in order to facilitate the operator’s task in locatingand identifying the various SRA Ls in the link. For a detailed description of theprocedure for drawing up a host table, please refer to the document "Installation oflink software".

9.2 Creation of the link map

The link map constitutes the necessary graphical interface for connection to the SRA Lwhen the link management software is used.To create the maps, it is necessary to use the proper Net Builder program. Such aprogram has the following features:

– If it is desired to have a graphical link layout as background, it is possible to importa drawing of the SRA L link in ".BMP" format.

– Positioning of SRA L icons in pre-arranged positions.

– Assignation of the relevant IP address to each SRA L. During definition of the hosttable, it is possible to use mnemonic acronyms instead of numeric IP addresses.

– Saving the created map in ".MAP" file format with the desired name.

In addition, the program allows modification of the pre-existing maps.A map is also required for connection to the local SRA L. The software is delivered witha standard map for connection to the local SRA L .To realise the SRA L link drawing one of the graphical application programs in Windowsmust be used (either in Windows 3.1/3.11 or in Windows 95/NT) which supports thegraphical ".BMP" format (e.g.: Paintbrush).The SRA L link drawing can be of any type, for example:

– a geographic map pointing out location of the various stations

– a block-diagram pointing out all link interconnections.

☞ The SRA L IP addresses have to be assigned in steps of two because for everySRA L an IP address corresponding to the F interface (service PC or router) isautomatically added. Such an address is equal to the SRA L IP address plus one;e.g. in case of Net-Mask = 255.255.255.0:• SRA L IP address = 150.166.32.2• SRA L F interface IP address = 150.166.32.3.It is advisable to follow a systematic rule such as using only even IP addressesfor the SRA L.

☞ An incorrect settin g in a static table can cause a wron g routin g of mana gementinformation into the link and hence ma y endan ger operation of the whole SRA Llink.



When creating the drawing please be careful to leave enough space in the various SRAL positions to allow for future positioning of the respective icons in order to end up witha clear and neat map. For help on how to use the Net Builder program please refer tothe document "Guide to use of Net Builder program".

9.3 Configuration of SRA L link parameters

Once the link plan is defined all link parameters must be assigned to the SRA Lequipment, taking into account the validity conditions provided by the software (refer topar. 10).

The following link parameters can be set through software:

– Equipment IP address and the corresponding Net-Mask (the same Net-Mask forthe entire SRA L link), according to the planning of the IP addresses of the SRA Llink.

– F interface parameters:• Communication protocol: PPP or SLIP. Preferably, always set the PPP

protocol. The SLIP protocol should be used only if the PC hardware does notsupport the PPP protocol. The PPP protocol allows the service PC to detectthe IP address assigned to the F interface automatically. On the contrary, ifthe SLIP protocol is used, it is necessary to set the IP address manually onthe service PC before connecting it to the SRA L.

• Baud-rate: 9600 bps or 19200 bps. Preferably, always set 19200 bps; 9600bps should be used only if the PC hardware does not support a baud-rate of19200 bps.

– Static routing table, if necessary. It is possible to set up to a maximum of threedifferent routings for each SRA L. For every routing it is necessary to specify thefollowing data:• the SRA L interface for which the routing is defined: F interface, V bus,

integrated R1 channel, integrated R2 channel (not available in (1+0) and(1+1) configurations)

• the network IP address and destination gateway address.

– Q-Adapter unit parameters (if installed):• IP address and relevant Net-Mask of the V interface for the connection

towards SRA L link, according to the IP address planning of the SRA L link.• IP address and relevant Net-Mask of the Ethernet interface for the connection

towards supervision system. Such parameters must be assigned by theadministrator of the used network to communicate with the supervisionsystem.

☞ When the settin g of SRA L link parameters is performed for the first time, it isnecessar y to isolate the SRA L itself be from the rest of the link. Otherwiseconflicts ma y occur in the link.

☞ The setting of the gateway IP address is only necessary in case of routing on aV bus, because on the V bus it is necessary to specify the SRA L of destinationwhile this is optional in other cases.In a SRA L link only a single default routing can be set (multiple transmission toall networks). To assign the default routing, set the IP address = 0.0.0.0.



• OSI/QD2 address of the Qx/QD2 interface. Such address must be assignedby the administrator of the supervision system.

– D channel Add/Drop on the 2 Mbit/s tributary streams (if it is necessary). It ispossible enable the D channel Add/Drop operation on 2 Mbit/s tributary streams,

selecting the tributary and the relevant slot to be used.

For help on how to use the Link Viewer program refer to the "Guide to use of Link Viewerprogram".

In case of SRA L in 2x(1+0) and A/D-RPT configuration, there are twoindependent D channels.The D channel setting is necessary only on the SRA Ls acting as branchingpoints towards other systems.

i



9.4 Creation of the host table

The creation mode of the host table is different depending on to the operating system ofthe service PC (see doc. “Installation of link software”):

– Windows 95/NTIn the "hosts" file, placed in the Windows 95/NT system directory (typically"c:\windows"), it is necessary to specify the correspondence between the SRA Lnumeric IP address and the corresponding mnemonic acronym. To open and editthe "hosts" file use an editor program. The file has to be saved in ASCII formatwithout any extensions in such a way that Windows 95/NT can detect it as a systemfile.

– Windows 3.11/3.11The special menu SetupTCP of the SuperTCP software must be used to specifythe correspondence between the SRA L numeric IP address and the relevantmnemonic acronym.

9.5 Testing of the SRA L link

After execution of the planning and configuration procedure of the SRA L link, the linkadministrator has to carry out, by means of the software utilities of the TCP/IP protocol,its testing to check that:1. There are no conflicts on the link.2. All SRA Ls can be reached and answer the connection request.3. All possible routes of the link are free of routing errors.

For more detailed information about the use of the software utilities refer to the Windows95/NT handbooks.



10 VALIDITY CONDITIONS OF TCP/IPPARAMETERS

10.1 General

The TCP/IP parameters that can be configured via software are the following ones:

– IP address of the SRA L and relevant Net-Mask

– static routing table

– connection parameters between SRA L and PC (F interface).

To minimize the possible presence fo malfunctioning TCP/IP configurations, thesoftware (Link Viewer program) provides some values that can not be assigned for eachsome values that can not be assigned for each TCP/IP parameter.The detection for each parameters of the validity conditions and of the not validity onesis based upon the RFC standards and upon the SRA L particular structure.The validity and not validity condition for the IP addresses and the Net-Masks contentsalso the combinations between the two parameters. In fact some values, considered asvalid if they are singularly taken into account, can define, if they are combined, some notvalid sub-network or host values.The setting of a not valid value is signalled by the software on the video through anegative answer like "out of range".Then it is provided a reset mode of the TCP/IP parameters.

10.2 Validity conditions for IP addresses and Net-Mask

10.2.1 IP addresses

– Only the IP addresses belonging to Class A, B and C are valid.

– The IP addresses = 127.X.X.X are not valid because they are reserved forloop-back.

– The IP address = 255.255.255.255 is not valid because it is reserved for "limitedbroadcast".

– The IP address = 0.0.0.0 is a particular case of the SRA L because it is reservedfor the reset of the TCP/IP parameters (refer to par. 10.5)

– For each Class, the IP addresses having the following characteristics are not valid:• all "1" in the network field• all "0" in the network field• all "1" in the host+sub-network field• all "0" in the host+sub-network fieldin fact such IP addresses are reserved ones (e.g. the IP addresses with all "1" arereserved for broadcast).

– For each Class, it is not valid the IP address having the host field such as to assignto the PC and IP address equal to the broadcast of that network.

Into the SRA L, the IP address of the PC is automatically assigned increasing of1 the IP address of the SRA L itself.i

10.2.3 IP address - Net-Mask combinations

For each Class, the IP address and Net-Mask combinations causing one of the followingsituations in the IP address are not valid:

– all "0" in the sub-network field

– all "0" in the host field

– all "1" in the host field (broadcast for that network)

– host field such as to assign to PC address equal to the broadcast for thatsub-network.

Here below there are some examples of not valid combinations for the Class A.

– Combination of IP address = 97.11.48.159 and Net-Mask = 255.255.255.224

Applying che mask, it is obtained the host field with all "1" (broadcast for thatsub-network).


Applying the mask, it is obtained a sub-network field with all "0".

Applying the mask, it is obtained a host field with all "0".

– Combination of IP address IP = 1.0.128.62 and Net-Mask = 255.255.255.192

Applying the mask, it is obtained a host field (111110) such as to assign to PC anIP address equal to the broadcast for that sub-network (all "1" in the host field).

10.3 Validity conditions for parameters of the static routingtable

Here below, there is the list of the validity conditions and of the not validity ones for eachparameter of the static routing table.Remeber that it is not possible to execute permanent settings for the static routing tableuntil the IP address of the SRA L has not been assigned.

– Routing interfaceThe setting of the interface devoted to the routing definition does not create specialtroubles because it is possible to select only the values present into the listdisplayed on the video.

– IP address of the destination network• Only the IP addresses belonging to Class A, B and C are valid• For each Class, the IP addresses, having all "0" or all "1" into the network

field, are not valid• For each class, the IP addresses equal to the following ones are not valid:

– default IP address of the PC– default IP address of the SRA L– current IP address of the SRA L

0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0

– IP address of the local sub-network– IP address for broadcast of the local sub-network.

– IP address of the gateway • The same validity conditions of the SRA L IP addresses are valid (refer to par.

10.2)• For each Class, the current IP address of the SRA L is not valid.

10.4 Validity conditions for the F interface parameters (PC)

The setting of the F interface parameters (link and baud-rate protocol) does not createspecial troubles because it is possible to select only the values present into the listdisplayed on the video.Check that the used hardware (PC and, in case of remote connection, modem) supportsthe executed settings.

10.5 Reset of the TCP/IP parameters

It is possible to execute the reset of the TCP/IP parameters assigning the IP address =0.0.0.0.This operation causes the deleting as of the IP address and of the relevant Net-Mask asthe settings into the static routing table.On the contrary, the protocol and the baud-rate relevant to the F interface remains thecurrent ones.Then the reset of the TCP/IP parameters is automatically executed when the followingconditions are present:

– when it is changed the IP address of the SRA L

– when during the start-up phase, the system detects some IP address andNet-Mask values or combinations not valid.



11 EXAMPLES OF SRA L LINK

Fig. 13, Fig. 14 and Fig. 15 show three examples of SRA L link:

– Stand-alone type SRA L link (refer to Fig. 13). This is a link without branchingtowards other link.

– Intranet type SRA L link (refer to Fig. 14). This is a link with branching towards othernetworks.

– Internet type SRA L network (refer to Fig. 15). This is a link connected directly tothe Internet network.

The example of Fig. 13 shows a SRA L link where a link administrator uses a Class BIP address with Net-Mask = 255.255.255.0, i.e. with the following structure:

The example of Fig. 14 and Fig. 15 shows a SRA L where a link administrator uses aClass B IP address with Net-Mask = 255.255.255.240, i.e. with the following structure:

The main characteristics pointed out by the three examples are the following:

– Use of a router for the connection to another network (Fig. 14) or to the Internetnetwork (Fig. 15). The router can be installed in the same site as the SRA L towhich it is connected to or even in another site (for example via modem).

– Use of even IP addresses in steps of two for the SRA Ls.

– The F interface IP address of the SRA L connected to the PC is equal to theaddress of the SRA L itself plus one.

For SRA L of Internet type, we can use a Server Proxy together with a PC for theconnection to SRA L link (see doc. “Connection to SRA L link”).i

12 MAIN PROBLEMS OCCURRING IN THESRA L LINK MANAGEMENT

12.1 Common problems in Windows 3.1/3.11 and Windows 95/NT

• F interface: no possibilit y to ne gotiate the TCP Protocol with the SRA L.Verify the correct configuration of the service PC (remote access or Ethernetnetwork board for Windows 95/NT, SuperTCP setup for Windows 3.1/3.11).In case the serial interface is used, check the interconnection cable PC - IDU.Check whether the SRA L is on and has completed the reset operation.

• F interface: durin g loadin g of the localsral ma p, the icon remains grey.Close the Link Viewer and check whether the TCP protocol is correctly operating.

• F interface: the o perator cannot remember the IP address of the SRA L.Estblish a connection with the SRA L using the default address (loca map) andcheck the IP address. As an alternative, execute Ping from DOS to check whetherthe protocol is operating. The SRA L will reply signalling its specific IP address. Inthis case, it will be the default address.

• F interface: the su pervision is lost when chan ging the SRA L IP address.Every time an IP address or the system type of the SRA L is changed, a newstart-up of the working session is required (application program and protocol).

• V bus: after havin g executed the connection, it is not possible to "see" theSRA L installed downstream of the bus.Check whether all the hosts on the V bus belong to the same sub-network. Checkwhether the V bus is has the correct terminations.

• Address plannin g: usin g Class A addresses, it is not possible to monitor allthe SRA Ls.Check whether for the Class A addresses a Net-Mask is used which is at leastequal to 16 (255.255.0.0).

12.2 Common problems in Windows 95/NT

• "hosts" file: after havin g updated the "hosts" file, the icons on the ma premain grey.The "hosts" file is read by Windows 95/NT only during the opening. To activateevery possible change on such a file, it is necessary to start Windows and the LinkViewer application again.

1 OVERVIEWThe link software is provided on CD-ROM, with the serial number and the passwordannexed.The installation CD-ROM contents:

– the software for the SRA L link management

– the SuperTCP program

– SRA L software plugs-in:• 8x2 Mbit/s software plug-in SRA L • 16x2 Mbit/s software plug-in SRA L • Full ODU software plug-in SRA L

– the drivers for the connection via cable for Windows 95/NT.

In case of installation on PC not equipped with CD-ROM drive, it is possible to obtainthe installation floppy-disks of the programs and the plug-in from the relevant copypresent on CD-ROM.

The SRA L link management program is composed by two application programs forWindows:

– Link Viewer, which constitutes the true control and configuration program of theSRA L link; for each type of SRA L, there is a specific plug-in software, whichmakes the Link Viewer program able to manage the equipment

– Net Builder, for the creation of link maps.

The installation and configuration of the TCP/IP protocol differs depending on thesoftware:

– Windows 3.1/3.11The TCP/IP protocol provided by the SuperTCP program is used. The TCP/IPprotocol is available only with RS-232C serial interface (PPP or SLIP protocol).

– Windows 95/NT 4.0The TCP/IP protocol provided by the operating system itself is used, availableeither with serial RS-232C interface (PPP or SLIP protocol) or Ethernet interface.If the serial interface is used, it is necessary to install the direct connection mode.It is necessary to install the SuperTCP program also in Windows 95/NT, if theoperator wants to use the PC to execute the download of the unit software

(Controller unit, Q-Adapter unit) from remote, by means of FTP.

4.4 Installation of SRA L software plugs-in

Once the LinkViewer software has been succesfully installed, we must install the plug-insoftware for the different SRA Ls.It is necessary to install only the plug-in software concerning the SRA Ls used in the link.

The Link Viewer program can recognize and, then, manage only the SRA Ls, whoseplug-in has been installed.The installation of a software plug-in causes:

– the capacity for the Link Viewer program to manage the corresponding type ofSRA L;

– the addition of the Help program, corresponding to this SRA L managementapplication program, in the Help menu of Link Viewer program.

To install a plug-in software, we must start the relative installation executable file fromCD-ROM or from floppy disk and, then, follow the instructions shown on the video.The installation program automatically copies the plug-in files in the same directory inwhich the Link Viewer software is installed.

After the plug-in installation, we must exit and, then, restart the Link Viewer program (ifit was already functioning) to apply the changes.

To install the plug-in software, the LinkViewer program must be alreadyinstalled; otherwise, install first the LinkViewer program and, then, the plug-in(see par. 4.3).

The installation procedure for each plug-in is described, in every detail, in thecorresponding SRA L OMN Manual.

5.5 Installation of SRA L software plugs-in

Once the LinkViewer software has been succesfully installed, we must install the plug-insoftware for the different SRA Ls.It is necessary to install only the plug-in software concerning the SRA Ls used in the link.

The Link Viewer program can recognize and, then, manage only the SRA Ls, whoseplug-in has been installed.The installation of a software plug-in causes:

– the capacity for the Link Viewer program to manage the corresponding type ofSRA L;

– the addition of the Help program, corresponding to this SRA L managementapplication program, in the Help menu of Link Viewer program.

To install a plug-in software, we must start the relative installation executable file fromCD-ROM or from floppy disk and, then, follow the instructions shown on the video.The installation program automatically copies the plug-in files in the same directory inwhich the Link Viewer software is installed.

After the plug-in installation, we must exit and, then, restart the Link Viewer program (ifit was already functioning) to apply the changes.

6 &5($7,21�2)�7+(�+267�7$%/(

The host table is an optional feature allowing to associate a mnemonic acronym witheach SRA L which can be used instead of the numeric IP address.Planning of the host table means definition of the correspondence between mnemonicacronym and numeric IP address for every SRA L in the link. This planning is anoperation reserved for the link administrator.

The creation modes for the host table differ depending on the software.

– under Windows 3.1/3.11 the SetupTCP application of the SuperTCP program isused to write the host table

– under Windows 95/NT a common editor program is used to write into the systemfile “hosts”.

To install the plug-in software, the LinkViewer program must be alreadyinstalled; otherwise, install first the LinkViewer program and, then, the plug-in(see par. 5.4.1).

The installation procedure for each plug-in is described, in every detail, in thecorresponding SRA L OMN Manual.

For more detailed information about the assigning criteria of the IP addressesfor the SRA L link refer to the “SRA L link management” document

It is always possible to update the host table after a compilation error or achange in the SRA L link.

– Use a common editor program to open the file “hosts” in the Windows 95/NTsystem directory (usually “c:\windows”).

– For every SRA L of the link specify the correspondence between the numeric IPaddress and the associated mnemonic acronym. During editing it is necessary to insert a tab or leave a free space between thenumeric IP address and the mnemonic acronym. Fig. 186 shows an example forthe file “hosts”.

– Exit from the file and save in ASCII format without extension, so that Windows 95can recognize the file as a system file.

1 OVERVIEWThis document describes the forms and the problems concerning the connection andthe access, via TCP/IP protocol, of the service PC to the SRA L link. These differaccording to:

– the operative system installed on the service PC (Windows 3.1/3.11, Windows 95/NT)

– the interface used on the service PC (serial RS-232C or Ethernet).

In Windows 3.1/3.11, only the connection on serial interface is available (connectionPPP or SLIP).In Windows 95/NT, either the connection on serial interface or on Ethernet interface areavailable.

2 MODES OF CONNECTION BETWEEN THESERVICE PC AND THE SRA L LINK

2.1 Direct connection on RS-232C serial interface

2.1.1 Overview

The service PC is directly connected, by a proper cable, to the local SRA L, which actsas link access point.Fig. 1 shows an example of direct connection on RS-232C serial interface.

Fig. 1 – Direct connection on RS-232C serial interface



2.1.2 Requirements of RS-232C serial cable

For the local connection between service PC and SRA L, a serial cable is requiredaccording to EIA RS-232C standard specifications. It must be a non-modem pin-to-pincable, equipped with a 9-pin male CANNON connector on the SRA L side.In this connection, the service PC is considered a DTE unit, while the SRA L (Controllerunit) is considered a DCE unit.Fig. 2 shows the connection between the SRA L (Controller unit) and service PC.

Fig. 2 – RS-232C connecting cable between SRA L and service PC



2.2 Remote connection on RS-232C serial interface

2.2.1 Overview

The use of a modem allows to establish a remote connection, using a RS-232C serialinterface, between the service PC and SRA L link, which acts as link access point. Fig. 3shows an example for a remote connection, realised via modem.

Fig. 3 – Connection on RS-232C serial interface

Under Windows 3.1/3.11, the utilisation of the remote connection requires aparticular configuration of the SuperTCP program.Under Windows 95/NT, the use of the remote connection re quires the installationand the confi guration of the modem used to re place the “direct connection”modem durin g the confi guration procedure (cfr. doc. “Installation of linksoftware” ).For more details about the confi guration and use of modems, refer to therespective handbooks.

i



2.2.2 Characteristics of the connection cables

The following is a list of requirements for the connection cables to be used:

– Connection between SRA L and modem.Use a standard cable for the DCE-DCE connection, because both SRA L andmodem are DCE units. The cable must be provided, on the SRA L side, with a 9-pinmale CANNON connector.

– Connection between PC (RS-232C serial port) and modem. Use a standard cable for the DTE-DCE connection, because the PC is a DTE unitand the modem is a DCE unit.

– Connection between modem and telephone line.The modem interface towards the telephone line is usually terminated with a 8-pinRJ45 standard jack.Some modems have two different interfaces (one for the switched line and one forthe dedicated line).

2.2.3 Characteristics and configuration of modems

2.2.3.1 Modem characteristics

The modems must be Hayes compatible and must support standard AT commands,with a minimum baud-rate of 19200 bps (SRA L transmission speed). This conditionrepresents a restriction for the entire system.In this case, the communication between modem and SRA L must run at 19200 bps,while a higher baud-rate can be used between modems, depending on the modemcharacteristics and the quality of the used line.

2.2.3.2 Modem configuration

The modem configuration can be performed:

– by PC, providing the modem with AT commands by means of a terminal emulatorsuch as the Windows 3.1/3.11 Terminal utility or the Windows 95 HyperTerminal.

– manually, using the modem control panel.

A variety of configurations, pre-defined by the manufacturer, is usually stored in themodem firmware. These cover a large field of applications.In this case, it is sufficient to load the most proper configuration according to the type ofused line (switched or dedicated) and to set the following commands:

– on modem, SRA L side:• disable every kind of flow control• disable every type of error correction, compression and auto-request• if a switched line is used, set the modem to auto-answer mode; this is usually

achieved by setting the AT command: “&S0=1”

– on modem, PC side:• disable every kind of flow control• disable every type of error correction, compression and auto-request



• if a switched line is used, set the CDC control in such a way that it is ignoredin the current connection and returns to the command mode when the DTRsignal switches from “High” to “Low”; this is usually achieved by setting the ATcommand: “&C”

• if a switched line is used, set the DTR control in such a way that it is ignoredin the current connection and returns to the command mode when the DTRsignal changes from “High” to “Low”; this is usually achieved by setting the AT

command: “&D”.”

It is recommended to store the default configuration in the modem memory,using the AT command: “&W” (modems use the default configuration atstart-up).

2.3 Remote connection on Ethernet interface via router

Using a router, we can implement the connection to the SRA L link from a service PC,inserted in an Ethernet context (Intranet or Internet).The router is connected in the network, on Ethernet interface, with the service PC andit is connected, directly or via madem, on RS-232C serial interface, to the SRA L whichacts as link access point.

Fig. 4 shows an example of remote connection by router.

Fig. 4 – Remote connection on Ethernet interface by router

The connection on Ethernet interface is not available in Windows 3.1/3.11.

For the forms of connection, configuration and use of the router, refer to theconcerning manuals.

2.4 Remote connection on Ethernet interface by Server Proxy

Using a Server Proxy, we can implement the connection to the SRA L link from a servicePC, inserted in an Ethernet context (Intranet or Internet).The PC, on which the Server Proxy is running, is connected in the network, on Ethernetinterface, to the service PC and it is connected, directly or via modem, on RS-232Cserial interface, to the SRA L, which acts as link access point.The Server Proxy must use the “direct connection via cable” modem for the dial-upconnection (PPP or SLIP protocol) to SRA L. The relative driver “mdmcbx.inf” isavailable on the CD-ROM with the provision of the link software.Fig. 5 shows an example of remote connection by Server Proxy.

Fig. 5 – Remote connection on Ethernet interface by Server Proxy

The connection on Ethernet interface is not available in Windows 3.1/3.11.i



3 ACTIVATION OF CONNECTION BETWEENSERVICE PC AND SRA L LINKThe forms to activate the connection between the service PC and the SRA L, which actsas link access point, differ according to the interface types:

– RS-232 serial interfaceIt is necessary to activate the dial-up connection to SRA L on the service PC,before running the Link Viewer program.

– Ethernet interfaceThe connection between the service PC and the SRA L is automatically activatedduring Windows 95/NT start-up.

3.1 Activation of dial-up connection to SRA L link in Windows3.1/3.11

The procedure to realize the dial-up connection to SRA L in Windows 3.1/3.11 is thefollowing:

– Click twice on SuperTCP icon in the Frontier Technologies group (Fig. 6).

– The SuperTCP Kernel program window is displayed (Fig. 7).

– Select Messages in File menu of SuperTCP Kernel (Fig. 8).

– The SuperTCP Kernel window (Fig. 9) is displayed. In this window, the messagesare displayed, relevant to serial communication between service PC and SRA Llink. In case of correct functioning, the message displaying stops on Link O pen.Click on Done to close the message window.

Using a router for the connection on Ethernet interface, we must activate theconnection between router and SRA L, before running the Link Viewer program.

Using a Server Proxy for the connection on Ethernet interface, we must activatethe dial-up connection to SRA L on the PC on which the Server Proxy is inexecution, before running the Link Viewer program.

If a modem is used in the connection, the communication via modem must beactivated first.

3.3 Activation of the dial-up connection to SRA L in WindowsNT

The activation procedure of the dial-up connection to the SRA L in Windows NT is thefollowing:

– First, check that the connection cable of the PC serial port is disconnected.

– In My Computer , click twice on Dial-Up Networking (Fig. 21).

– The Dial-Up Networking window is displayed (Fig. 22). Select SRA L connectionin Phonebook entry to dial and click twice on Dial .

– The Connect to SRA L connection window is displayed (Fig. 23). Click on OK.

– The Pre-Dial Terminal Screen window is displayed (Fig. 24). Now connect theconnection cable to the PC serial port.

– To ensure that the hardware is correctly working, wait for the data stream in the

Pre-Dial Terminal Screen window (Fig. 25) and, then, click on Continue .

– The Operator Assisted or Manual Dial window is displayed (Fig. 26). Click onOK.

– The After Dial Terminal window is displayed (Fig. 27).Wait for the end of the data stream into the After Dial Terminal window and, then,

click on Done .

– The Connection Complete window is displayed (Fig. 28). Click on OK.

– When the connection is established, the Dial-Up Networking Monitor window isdisplayed (Fig. 30). Into the system application box (lower corner on the right of thedesktop), the monitor RAS icon is displayed (Fig. 29).The Dial-Up Networking Monitor window allows to display the information, the

If the connection uses a modem, the communicationvia modem must beactivated first.

The need to begin the operations with the cable disconnected depends on thefunctioning mode of the Windows NT RAS service.The RAS service, in fact, supports only devices able to manage the “DataTerminal Ready” signal (“CD” line), because it needs that, at the beginning, the“CD” signal is deactivated.Into the SRA L, the management of the “CD” signal is not provided (the signal isalways activated).In Windows NT Server, if the RRAS service is installed instead of RAS service,we can start the operations with the cable connected.

The packages of the TCP/IP protocol start and end with the character “~”.

While the local equipment is transmitting the data, the dial-up connection cannot be established.

details and the preferences concerning the connection on progress (Fig. 30,Fig. 31, Fig. 32).The automatic displaying of the Dial-Up Networking Monitor window is apreferential setting. However, it is always possible to open the window clicking

twice on the monitor RAS icon (Fig. 29).

Fig. 21 – Activation of the dial-up connection to SRA L in Windows NT (1/13)

☞ If the dial-up connection between the SRA L and the PC is interrupting, shouldno traffic be on the serial line, it is necessary to keep the dial-up connectionactivated in one of the following ways:

– sending a cyclic ping (“ping-t”) (cfr. par. 6.2) to the SRA L (cfr. Fig. 33)

– starting up the Link Viewer program.

Exiting from the Link Viewer program, the connection must be closed with thefollowing procedure:

– move the mouse on the monitor RSA icon (Fig. 29) and click on its rightbutton

– the dial-up menu (Fig. 34) is displayed; click on Close.

4 LOADING OF SRA L CONFIGURATION FILEIn Link Viewer program, we must load the SRA L configuration file to activate itsmanagement and control operative functions, that is to access the SRA L.To load the configuration file, we must open the map containing the relative SRA L and,then, activate the access towards the SRA L.

4.1 Map opening

The map is the graphic interface for accessing the SRA L in Link Viewer program. If themap Security is enabled, the system requires to insert the user class and the relativepassword (see Fig. 35) at map opening.At map opening, Link Viewer tries to connect to every enabled SRA L; for every SRA L,the connection phase takes places in the following way:

– should a communication error be detected (non-existent equipment, for instance),an icon is displayed, indicating that the SRA L is disconnected (involuntarydisabled status)

– should the connection be successful, the program tries to identify the SRA L:• if the identification is successful, a predefined icon is displayed, indicating the

SRA L type (see Fig. 36); furthermore, the equipment menu is added• if the identification is not successful (the plug-in for this kind of SRA L is not

installed, for instance), a icon is displayed, indicating that this SRA L type is

not supported.

The program cyclically makes an attempt for an automatic connection towards the SRALs which are in involuntary disabled status.The program carries out a periodic polling to monitor the connection and alarm status(severity) of every SRA L. The possible values of severity for a SRA L are the following:

– disconnected

– normal

– test

– warning

– minor

– major

– critical.

A specific icon signals the involuntary disabled status for the SRA L.

If all the following conditions are present, some connection troubles could occurusing the local map (default local IP address = 192.168.255.3):• dial-up connection by RS-232C serial interface• TCP/IP protocol used also by other interfaces (e.g.: Ethernet for local

network, etc.)• local equipment with IP address correctly configured.In this case, it is necessary to create a new map with the effective IP address (seepar. 6) of the equipment, because the local map can not be used.

i

Fig. 36 – Example of local map



4.2 Access towards SRA L

The ways for accessing the SRA L differ depending on enabled/disabled status ofsecurity access (login phase):

– Access without login (equipment Security disabled):the user accesses with user class ADMIN, with the only restriction that he cannotmodify the Security settings

– Access with login (equipment Security enabled):• equipment Security enabled:

the user accesses with the same user class of the map’s one (Opencommand in equipment menu or double click on the icon) or with a user classhaving rights inferior to the map’s one (Open User command in equipmentmenu)

• equipment Security disabled:the user accesses with the desired user class.

When the access towards the SRA L is commanded, the Link Viewer program starts toload the configuration file for the equipment (see Fig. 37).If the login phase is successfully executed, the window Security is displayed (seeFig. 38), in which the user is requested to insert the user class (see Fig. 39) and therelative password (see Fig. 40).

When the configuration file and the concerning controls have been loaded, if no errorhas been taken place, the access towards the equipment is activated.The dinamic part is added in the equipment menu; this part is the operative menu forconfiguration and control.

Fig. 37 – Window of the loading of SRA L configuration file

It’s possible to force the login phase, independently from the status (enabled ordisabled) of the equipment Security, adding the option -p in start-up commandwithin the Link Viewer program.

If the Security map is enabled and the password is already stored in the map file,we don’t need to insert the password, because it is automatically inserted by theprogram.

5 ROUTING TROUBLES WITH THE TCP/IP PACKETS IN

WINDOWS 95/NT

5.1 Common cases of TCP/IP packet routing

The TCP/IP protocol can manage different interfaces (serial line, Ethernet network, etc.)according to the network functions present on the service PC (PC - equipmentconnection, Internet connection, company LAN connection, etc.).Then, some routing troubles with the TCP/IP packets can occur.The most common cases are the following ones:

– TCP/IP on serial line only If on the service PC the TCP/IP protocol manages only the serial line and it hasbeen correctly configured, all the sent packets are forwarded on the serial line.In this case, if the equipment is directly connected to the service PC, it is alwaysreachable.In case of troubles, it is possible to force the packet forwarding on the serial lineselecting the option “Use default gateway on remote network” into the configurationwindow of the TCP/IP protocol for the serial line (Fig. 41 and Fig. 42).

– TCP/IP on Ethernet network only If on the service PC the TCP/IP protocol manages only the Ethernet network andit has been correctly configured, all the sent packets are forwarded on the Ethernetnetwork.In this case to reach the equipment, it is necessary to configure correctly theinvolved gateways.

– TCP/IP as on serial line as on Ethernet network If on the service PC the TCP/IP protocol manages as the serial line as the Ethernetnetwork, for each sent packet the system has to decide the use of the serial line orof the Ethernet network. In each case, it will be used only one of the two routes.The choice of the route to be used depends on the IP address of the target, on theconfiguration of the TCP/IP protocol and on the equipment connected to the serialline.If on the serial line, it is connected an equipment with IP address X.X.X.X, therelevant serial port of the service PC will have an IP address equal to the one ofthe equipment plus 1 and a Net-Mask that depends on the class of its own IPaddress (on the contrary, it does not depend on the equipment Net-Mask). TheEthernet card of the service PC has an IP address and a Net-Mask presetted bythe user.A packet with IP address X.X.X.X is forwarded:• on the serial line, if it belongs to the sub-network defined by the IP addess and

by the Net-Mask of the service PC serial port (For instance: in the case ofserial port with IP address = 150.160.170.181 and Net-Mask = 255.255.0.0,the addresses that belong to the sub-network are 150.160.X.X)

• on the Ethernet network, if it belongs to the sub-network defined by the IPaddess and by the Net-Mask of the service PC network card (for instance: inthe case of Ethernet card with IP address = 138.132.140.104 and Net-Mask= 255.255.255.0, the addresses that belong to the sub-network are138.132.140.X).

To route correctly some packets with an IP address not compatible neither with the



serial line nor with the Ethernet network, it is necessary to respect the followingindications:• to forward the packets on the serial line, select the option “Use default

gateway on remote network” into the configuration window of the TCP/IPprotocol for the serial line (Fig. 41 and Fig. 42); this configuration affects allthe programs that use the TCP/IP protocol (for instance: Internet Explorer,Netscape Communicator, etc.)

• to forward the packets on the Ethernet network, define and configure agateway for the Ethernet interface.

5.2 Commands to solve reachability problems

5.2.1 The “winipcfg” command

The “winipcfg” command is available only in Windows 95. It allows to detect (see.Fig. 43) the IP address and the Net-Mask of the service PC network card and serial portand, then, the IP address of the local equipment. To run this command it is necessaryto execute the following procedure: Start → Run → winipcfg

Fig. 43 – The “winipcfg” command

Net-Mask of the PC onthe Ethernet network.

IP address of the PC onthe Ethernet netwrok.

Net-Mask of the PC -equipment network.

IP address of the PC onthe PC - equipmentnetwork. To get theequipment IP address, itis necessary to subtract1 (into this example theequipment IP addressis: 192.168.255.3).



5.2.2 Dial-up monitor window in Windows NT

In Windows NT, it is possible to know the IP address of the local equipment, connectedto the serial line, by means of the dial-up monitor window.To access to the monitor dial-up window (see Fig. 44), it is necessary to click on themodem icon present into the area of the system applications (lower right corner of thedesktop).

6 TROUBLES IN THE DIAL-UP CONNECTIONTO THE LOCAL EQUIPMENT

6.1 Local equipment not reacheable using the default local IPaddress

If all the following conditions are present:

– connection to the local equipment on serial line (dial-up connection)

– presence, at the same time, of at least two interfaces of the PC (e.g.: Ethernetnetwork card and dial-up connection) using the TCP/IP protocol

– local equipment with IP address correctly configured,

the local equipment can result not reachable using the default local IP address(192.168.255.3).In this case, it is not possible to use the default local map. Then it is necessary to createby means of the Net Builder program (refer to the “Guide to use of Net Builder program”document) a new map with reference to the real IP address of the local equipment (referto par. 6.3).

6.2 Deactivation of the dial-up connection for traffic absencein Windows NT

In Windows NT, the dial-up connection between the local equipment and the PC can beinterrupted if there is not traffic on the serial line.

To keep always activated the dial-up connection, it is advisable to forward a cyclic pingtowards the local equipment, using the following command from DOS prompt (Fig. 49):“ping –t <IP_address> ”the “<IP_address>” is the real IP address of the local equipment (refer to par. 6.3) and“-t” is the cyclic execution option.If the dial-up connection is interrupted for traffic absence, it is necessary to execute theactivation procedure of the dial-up connection again (refer to par. 3.3).In this case, it is advisable to execute the following procedure to avoid disconnectingnewly the cable from the PC serial port:

– move the mouse on the RAS monitor icon (Fig. 50) in the system application box(lower corner on the right of the desktop) and click on the right push-button

– the dial-up menu is displayed (Fig. 51); start up again the connection procedureselecting SRA L connection under Dial .

The execution of the Link Viewer program causes a permanent data stream onthe serial line and, then, it keeps always activated the dial-up connection.i

1 PROGRAM FUNCTIONSThe Link Viewer program is an application one for Windows 3.1/3.11 and Windows95/NT environment for the supervisory of a radio equipment link (NE).The Link Viewer program allows the navigation inside the radio link, it displays the NEoperating status and allows interacting with them.The radio link to be managed is represented through a link map created by means of theNet Builder program (refer to the “Guide to use the Net Builder program”). Thisdocument contains all the information concerning the link configuration and it constitutesthe graphical interface for the access to the NEs.A radio link is usually composed by two radio equipments (two front-end terminals); itcan contain up to three radio equipments in case of add-drop configuration (twoterminals placed at the end and one intermediate add/drop repeater).Then, the Link Viewer program is not able to open maps that contain sub-maps andmore than three NEs.The Link Viewer program can manage radio links of different type:

– link of SDH radio equipments

– link of PDH radio equipments

– link of point-multipoint radio equipments.

The Link Viewer program allows the execution of the following main functions:

– to open and to display the link map (one link map);

– to set the connection with the NEs, activating such a connection at the mapopening;

– to execute, by means of a cyclic polling, the monitoring of the NEs connection andalarm status;

– to access to the single NE, that is to load the relevant configuration files andoperating menus;

– to configure and to control each single NE, through the relevant operating menu;

– to manage the security access (Security) to the NEs, that is to allow the accessonly to authorized users by means of passwords.

For each type of radio equipment, it is provided a specific software plug-in thatconstitutes the configuration and control application program.At the map opening, the Link Viewer program automatically detects the type of thepresent radio equipment, if the relevant plug-in has been installed. If it is present aparticular type of radio equipment and the relevant plug-in hasn’t been installed , theLink Viewer program detects its presence, but it is not able to recognize it and then tomanage it.It is possible to execute the installation of a plug-in for every type of radio equipment,also after the installation of the Link Viewer program. In such a case, if the Link Viewerprogram is already running, it is necessary to exit from the program and then to start upit again, to allow the loading of the new plug-in.



2 USER INTERFACEThe Link Viewer program is provided with a Windows typical user interface.The program screen page (see. Fig. 1) consists of the following elements:

– title bar

– menu bar

– status bar

– displaying (working) area

– tool bar

– scroll-bars

2.2 Menu bar

The menu bar displays the following basic program menus:

– File

– Options

– Window

– Help .

When a map has been opened, the menu bar displays also the menus of the objectspresent into the map itself:

– Net-Element It contains the menus of the NEs present on the map.

– <name_NE>It is the menu of the actually selected NE.

The menus are Windows type ones. To select an option into a menu, it is necessary toposition the mouse on the menu, to press the left-hand push-button of the mouse and,keeping it pressed, to select the desired option; then release the left-hand push-buttonof the mouse to activate the selected option.

2.3 Status bar

The status bar displays messages and informations useful for the operator (the meaningof the menu commands, the status of the program or of the function actually onprogress, the details concerning the fields of the configuration and control windows,etc.).

2.4 Working area

The maps and the windows, opened using a command or selection, are displayed intothe working area. It is possible to display more windows at the same time, even if theybelong to different NEs.The title of a window is always preceeded by the name (IP address or mnemonicnemaplete) of the NE to which it is referred.The fields of the NE configuration and control windows can be of the following two types:

– read only: files concerning the status and alarm signals or not modifiableparameters

– read-write: fields concerning modifiable parameters.

It’s possible to modify the values of the fields, depending on the user class used toaccess to the NE:

– Read Only: it is possible only to read the values of the fields, not to change them

– Read Write: it is possible to change the values of the fields with the exception ofthe ones relevant to the windows reserved for the Admin user class

– Admin: it is possible to change the fields of every window.

Usually, it is possible to execute the following operations on the read-write type fields:



– Selection of a valuePosition the mouse on the desired field and click. The window FIELD EDITING(see Fig. 2) is displayed with a box that lists the available values for the selectedparameter. Position the mouse on the desired value and click for selection; click onOK button to confirm the selection

– Data entry (numbers or strings)Position the mouse on the desired field and click; The window FIELD EDITING(see Fig. 3) is displayed with a box for the data entry. Position the mouse on thebox and click for selection; use the keyboard to enter the data into the box and clickon OK button to confirm the entry.

At the opening of a window, the values to be displayed into the fields are get by the NE.Some fields can point out, by means of blinking, the modification of their value. It ispossible to stop the blinking through the “F3” push-button.If the value of a field hasn’t been get by the NE yet , the field can not be modified.When the value of a field is modified, the request for modification is sent to the NE. Thenthe program waits for the NE answer. If the NE rejects the modification, an errormessage is displayed. If the field is a numeric type one, the program, before sending therequest for modification to the NE, executes a check on the validity range of the currentparameter. If the value is out of the validity range, an error message is displayed.The messages concerning the windows and the objects inside the windows (fields,push-buttons) are displayed in the status bar.Optionally, some acoustic signals can be coupled to the messages (both to the errormessages and to the modification ones).A special management characterizes the action windows that are used to execute someactions on the NEs.Every action window is provided with two push-buttons for the execution command andfor the interruption of the action. These push-buttons are usually called OK and Cancel .It is possible to open only one action window at a time. Then, when an action windowhas been opened, it is possible to change only the values of the fields inside the actionwindow itself.At the opening of an action window, the possibility to modify the fields belonging to otherwindows is disabled.

3 PROGRAM START-UPBefore starting-up the Link Viewer program, it is necessary to check the activation of theconnection between the PC where there is the program and the radio link.The connection modes between the PC and the radio link depends on several factors,such as for instance the following ones:

– the operating system present on the PC

– the interface type used on the PC for the connection (serial RS-232 or Ethernet)

– the radio equipment type present into the link

– the possible use of modems and/or routers

– the possible use of a proxy.

For a more detailed description of the connection modes and of the relevant activationprocedures, refer to the document “Connection to the Radio Link”.

3.1 Program start-up under Windows 3.1/3.11

The start-up procedure of the Link Viewer program under Windows 3.1/3.11 is thefollowing one:

– Click twice on the Link Viewer icon into the LinkViewer group (see Fig. 4).

– At the beginning, the program presentation window is displayed (see Fig. 6) and,after some seconds, the program base window is displayed (see Fig. 7). Clickingon the presentation window, it is possible to exit, to close the window itself and topass directly to the program base window.

3.2 Program start-up under Windows 95/NT

The start-up procedure of the Link Viewer program under Windows 95/NT is thefollowing one:

– Click on the Start push-button and, into the Programs menu, select theLinkViewer directory and, then, Link Viewer (see Fig. 5).

– At the beginning, the program presentation window is displayed (see Fig. 6) and,after some seconds, the program base window is displayed (see Fig. 7). Clickingon the presentation window, it is possible to exit, to close the window itself and topass directly to the program base window.

3.3 Opening of the link map

After having started the Link Viewer program, it is necessary to open the link map usingthe Open Map command of the File menu to access to the radio link (refer to par. 5.1.1).Before opening the link map, the Link Viewer program checks its congruence (the maphasn’t to contain sub-maps or more than three NEs).Each NE of the map is represented through an icon and a label. The icon type and thelabel background colour show the NE status.At the map opening, the Net-Element menu is added in the menu bar. Inside this menu,one menu for each NE of the map is created .Then, on the side of the Net-Element menu, the menu relevant to the actually selectedNE is always displayed (<name_NE> ). This feature allows executing the commands onthe selected NE without searching every time the relevant menu under the Net-Elementmenu. Changing the selected NE, also the <name_NE> menu changes.At the map opening, the program tries to connect to all the enabled NEs. For each NE,the connection phase is executed as described below:

– if an error during the communication is detected (for instance: not existing NE), anicon showing that the NE is not connected is displayed (not intentional disablingstatus)

– if the connection is successfully executed, the program tries to recognize the radioequipment type:• if the recognition is successfully executed, the relevant configuration file is

loaded and a pre-defined icon showing the radio equipment type is displayed.Then, into the corresponding NE menu, the operating menu that allows theNE configuration and control is added.

• if the recognition is not successfully executed (for instance: the plug-in forsuch a type of radio equipment is not installed), an icon showing that the radioequipment type is not supported is displayed.

The program cyclically executes an automatic connection attempt towards the NEs thatactually are in the not intentional disabling status.It is always possible to know the cause of the disconnection for a NE. Positioning thecursor on the icon of a disconnected NE, a message is displayed into the status barshowing the reason for the disconnection.The program executes a periodical polling to monitor of the connection and alarm(severity) status of the NEs. The possible values of severity for a NE are the followingones:

– disconnected

– normal

– test

– warning

– minor

– major

– critical.

The status of a intentional disabling for a NE is signalled through a proper icon.



3.4 Parameters on the control line of the Link Viewer program

It is possible to start-up the Link Viewer program by inserting on the control line thefollowing parameters:

– -pIt allows forcing the execution of the login phase during the access to a NE,independently from the enabling status of the NE Security (refer to par. 4.3).

– -traceIt allows activating the tracing management of the link operations.

– -map <name_map>At the opening of the map displayed into the <name_map> field, all the not disabledNEs are connected and sequentially opened.

– -ip <address_IP> -pa <address_proxy> -pp <port_proxy>It allows creating a new map with the NE having the specified IP address. Thebackground is the same one used for the configuration and control windows of theNE.If the connection uses a proxy, it is possible to specify the proxy address and port.At the map opening, the NE is connected and opened.

– -nologoIt allows preventing the displaying of the presentation window (logo) at the programstarting-up.

Each parameter can be written without distinction in capital letters or in small letters andit can be preceded by the character “-” or “/”.



4 SECURITY

4.1 NE Security

The Security allows the access to NE only to the authorized users. Each user ischaracterized by a user class and by a password. The user class defines the accessprivileges to the NEs.The Security configuration (enabling status and password) is specific for each NE andit is stored into the NE memory.The system provides the following three different user classes:

– Read Only: it allows the access to the functions in reading mode only;

– Read Write: it allows the access to the functions as in reading mode as in writingone, with the exception of the functions reserved for the Admin user class. For suchfunctions, the access is in reading mode only;

– Admin: it allows the access to all the functions as in reading mode as in writing one.

It is available also the Diagnostic user class, but only for the use inside the factory.It is possible to set/change the Security configuration by the NE operating menu, only ifthe access is executed using the Admin user class. When the access to a NE takesplace with enabled Security, the login phase is executed: it consists of the activation ofa window where the user has to specify the user class and the relevant password.It is always possible to force the execution of the login phase, independently from theenabling status of the NE Security, starting-up the Link Viewer program with the -poption (refer to par. 4.3). In case of NE with disabled Security and Link Viewer programstarted-up without the -p, option, it is possible to access to the NE with the Admin userclass. The only restriction is that it is not possible to change the settings relevant to theSecurity (enabling status and password). The Security enabling prevents the connectionto a NE of more operators at the same time with the Admin or Read Write user class,preventing conflicts and configuration errors.

4.2 Map Security

It is available a map Security with the following functions:

– to allow the map opening to authorized users only. The user classes are the sameones provided for the NEs;

– to associate all the passwords of the link map NEs to a single map password, foreach user class.

The map Security allows the user to access to the map and to its NEs with his authorizeduser class, using the map password only.The configuration of the map Security can be executed by means of the Net Builderprogram (refer to document “Guide to use of Net Builder program”). This programallows:

– enabling/disabling the map Security

– setting/changing the access passwords to the map for the several user classes;

– storing, into the map file, the access passwords to the NEs for the several userclasses.



If the map Security has been enabled, it is possible to access to the NEs with theSecurity enabled, using the same user class used for the map opening:

– if the password for such a user class has just been stored into the map file, it is notnecessary to type the password, because it is automatically inserted by theprogram;

– if the password for such a user class has not just been stored into the map file or itis not the correct one, it is requested the manual insertion of the password.

Using the Open User command of the NE menu (refer to par. 5.2.2), it is possible, whenthe map Security has been enabled, to access to a NE that has the Security enabledwith a desired user class, that can be different from the one used for the map opening:

– if the selected user class has rights equal to or lower than the ones relevant to themap user class, the password is automatically inserted by the program (naturally,if the password has just been stored into the map file);

– if the selected user class has rights higher than the ones relevant to the map userclass, it is necessary to insert manually the password, also if the password itselfhas just been stored into the map file.

In case of map Security enabled, if the password of a NE is changed through therelevant operating menu, the map file is automatically updated with the new password.In the same way, if the access to a NE is successfully executed using a passworddifferent from the one stored into the map file, the map file is updated with the correctpassword.

4.3 Forcing procedure of the login phase

It is always possible to force the execution of the login phase during the access to a NE,independently from the enabling status of the NE Security, starting-up the Link Viewerprogram with the option -p (refer to par. 3.4). The relevant procedure is the followingone:

– Windows 3.1/3.11Start-up the program selecting the Run option into the File menu of the ProgramManager and writing/selecting the following command line (see Fig. 8):c:\<path>\link16.exe -pwhere <path> is the path relevant to the “link16.exe” file for the Link Viewerprogram starting-up, pointed out into the window of the program properties (seeFig. 9). To display the window of the properties, select the program icon and then,select the Properties option in the File menu of the Program Manager.It is possible to add the -p parameter, to force the access with Security, directly intothe command line (Command Line ) of the feature window (see Fig. 9). In thiscase, start-up the Link Viewer program using the standard procedure (refer to par.3.1).

– Windows 95/NTStart-up the program clicking on the Start push-button, selecting the Run optionand writing/selecting the following command line (see Fig. 10):“c:\<path>\link16.exe” -pwhere <path> is the path relevant to the “link16.exe” file for the Link Viewerprogram starting-up, shown into the window of the program properties (seeFig. 11).



To display the window of the properties, select the Link Viewer program icon, clickon the mouse R.H. push-button and then, select the Properties option. It ispossible to add the -p parameter, for the access forcing with Security, directly intothe command line (Target ) of the feature window (see Fig. 11). In this case,start-up the program using the standard procedure (refer to par. 3.2 ).

5 DESCRIPTION OF THE MENUS

5.1 File Menu

The File menu (see Fig. 12) allows to open and to close a map, and to exit from theprogram.Between the Print to File and Exit commands, the system displays the names of thelast opened maps in such a way to allow a quick selection of the maps themselves.

Fig. 12 – File menu

5.1.1 Open Map

The Open Map command allows opening the link map (see Fig. 13). The filesconcerning the maps have the “.MAP” extension.In case of map opening with Security enabled, it is displayed the window for the userclass selection and for the insertion of the relevant password (see Fig. 14).A map is not open, if it contains some sub-maps or more than three NEs, because theprogram recognizes that it is not a link map. In this case, an error message is displayed(see Fig. 15 and Fig. 16).The Open Map command is active only when no map has been opened.

5.2.2 Open User

The Open User command allows, when the map Security is enabled, to open the NEwith a user class different from the map one. It is displayed the selection window of theuser class. This operation adds, to the NE menu, the corresponding operating menu forthe radio equipment configuration and control.The Open User command constitutes an alternative to the Open command and it isdeactivated in case of map Security disabled or if the NE is disabled or it has alreadybeen opened.



5.2.3 Close

The Close command allows closing the NE.This operation causes the closing of all the NE configuration and control windows andthe removal of the operating menu from the NE menu.The Close command is activated only if the NE has been opened.

5.2.4 Enable

The Enable command allows to enable the connection towards the NE.The command is activated only if the connection towards NE is disabled.

5.2.5 Disable

The Disable command allows to disable the connection towards the NE.The command is activated only if the connection towards NE is enabled.



5.3 Options menu

The Options menu (see Fig. 25) allows setting the signalling modes (both the visualmode and the acoustic one) of statuses and events used into the map and into theconfiguration and control windows of the NEs.Then, it is provided with the commands (“bring at front”, “bring at background”) relevantto the window of the link map.

Fig. 25 – Options menu

5.3.1 Colors

The Colors command allows specifying the displaying colour, according to the severity,to the object icons into the map and to the fields into the NE configuration and controlwindows.For the icons, the severity is shown by the background colour of the labels relevant tothe icons themselves, while for the fields of the configuration and control windows, theseverity is shown by the foreground colour of the fields themselves.Into the COLOR SELECTION window (see Fig. 26), that is opened using the Colorscommand, it is possible to select the colour to be associated to each level of severity.Two proper columns (Field Sample and Icon Sample ) show the displaying layout of thecolours for the fields and for the icons.Tab. 2 shows the default configuration of the colours.

5.3.3 Sounds

The Sounds command allows specifying the acoustic signals (sounds) to be used tosignal the status changes of the NEs.If the icon of a NE is blinking on the map, it means that its status is changed. It is possibleto couple a sound to such an event. This sound can be different according to the status(severity) of the NE.One single sound at a time is emitted, with a minimum time between two successivesounds defined by a timer.In case of status changes of more NEs, the sound associated to the status with thehighest severity among the ones of the NEs that are blinking on the map is emitted.Into the Map Sounds Selection window (see Fig. 31), that is opened using thecommand Sounds , it is possible to execute the following actions:

– to enable/disable the use of the sounds (Sounds enabled option)

– to couple to each severity a specific sound (Sound name )

– to set the minimum time (Interval between sounds ), expressed by seconds,between two successive sounds.

If some changes to the sound configuration have been executed, exit from the MapSounds Selection window (see Fig. 31) clicking on OK button to apply the newconfiguration.Each available sound can be heard pressing the Play push-button, the Stoppush-button stop the execution of the sound actually on progress.It is possible to assign to all the events the deafult sound (“beep”), clicking on Default .If some changes to the sound configuration have been executed, exit from the MapSounds Selection (see Fig. 31) clicking on OK button to apply and activate the new



configuration.

1 PROGRAM FEATURESThe Net Builder program is an application program for Windows 3.1/3.11 and Windows95/NT: it allows to create/change network/link maps constituting the graphical interfaceof the Net Viewer/Link Viewer program for connection with radio equipment (NE). Then,this program allows setting the parameters for the security access (Security) to the mapand to the NEs. This program is intented for network/link administrators.To create a map, following this procedure:

– compose the radio equipment network/link drawing, using a common graphicalWindows application supporting the “.BMP” graphical format (e.g. Paintbrush)

– import into Net Builder the radio equipment network/link drawing, that constitutesthe map background

– apply the NE icons in the predefined positions on the drawing

– assign the corresponding IP address (that has to be a univocal) to each NE

– eventually, set the passwords for the security access to the map and to the radioequipments

– save the map with the desired name in a “.MAP” format file

It is possible to create also some maps with tree structure, that is composed by a mainmap and one or more sub-maps in cascade. The sub-maps allow to group the NEs inthe desired mode and with more levels. The program is equipped with a standard mapfor connection to the local radio equipment.

The radio equipment network/link drawing can be of any type (e.g. geographical mapindicating the location of the various stations, a block diagram showing all thenetwork/link interconnections, etc...). During the composition of the drawing, sufficientspace must be left in the position of the NEs to allow subsequent positioning of thecorresponding icons, in order to obtain a orderly and readable map.

Fig. 1 shows an example of the radio equipment network/link map.

It is possible to use a mnemonic acronyms instead of the numeric IP addressesif it has been defined a host table.

☞ If the operator wants to create a personalized local map, it is necessary to assignthe numeric IP address 192.168.255.3 which constitutes the predefined and nonmodifiable local connection address for every radio equipment.

A link map has not to contain sub-maps or more than three NEs, because theLink Viewer program is able only to open maps that comply with suchrequirements.

4 MENU DESCRIPTION OF THE MENUTOOLBAR

4.1 File menu

The File menu (see Fig. 8) allows to open, to save, to close a map and to exit from theprogram.Between the commands Save As and Exit , the system displays the name of the last fourmaps that have been opened, to allow a quick selection of the maps themselves.

Fig. 8 – File menu

4.1.1 New

The New command allows to create a new map.A default name is assigned to the new map and this map is not associated to anybackground drawing.The New command is always active.

4.1.2 Open

The Open command allows to open a preexisting map (see Fig. 12); the files of thesemaps have the extension “.MAP”.If the operator opens a map with enabled Security, it is displayed the window for theselection of the user class and for the insertion of the relevant password (see Fig. 13).The Open command is always active.

Fig. 9 – Window for the Open command of the File menu



Fig. 10 – Security window for map opening

4.1.3 Close

The Close command allows to close the current map.It is requested to confirm the saving of the possible modifications applied to the map(Fig. 11).The Close command is active only if at least one map has been opened.

Fig. 11 – Saving confirmation window of the map changes

4.1.4 Save

The Save command allows to save the current map with the current name.This command is activated in the following cases:

– If a new map has been created and there is a background drawing or at least a NE

– if an already existing map has been opened and at least one modification has beenexecuted .

The system assigns the extension “.BAK” to the map file with the same name alreadypresent on the hard-disk.

4.1.5 Save As

The Save As command allows to save the current map, specifying the desiredidentification name and path (Fig. 12).By default, the destination directory is “..\MAP”.If a map file with the same name already exists into the destination directory, the systemrequests the saving confirmation (Fig. 13) and it assigns the extension “.BAK” to the filewith the same name.The Save As command is active if at least one map has been opened.



Fig. 12 – Window for the Save As command of the File menu

Fig. 13 – Savin g confirmation window for the Save As command

4.1.6 Exit

The Exit command allows to exit from the program.If a map has been created or modified but not saved, it is requested the confirmation atthe program exit (Fig. 14) and at the map saving (Fig. 15).The Exit command is always active.

Fig. 15 – Confirmation window for the map saving at the program exit



4.2 Edit menu

The Edit menu (Fig. 16) makes available all the commands necessary for the operationson the maps and on the relevant objects.All the commands in Edit menu are disabled if no map is open.

Fig. 16 – Edit menu

4.2.1 Open Map

The Open Map command allows to open the selected sub-map.This command is activated only if it has been selected a sub-map.It is possible to open a sub-map also with a double clicking on the relevant icon.

4.2.2 New

The New sub-menu (Fig. 17) contents the commands for the insertion of new objects(NEs and sub-maps).The commands of the New sub-menu are deactivated if it has been selected a NE.

Fig. 17 – New menu

4.2.2.1 Net-Element

The Net-Element command allows to insert a new NE into the current map (main mapor sub-map). After this command, the system opens the properties window (Fig. 18),because the insertion of a new NE needs for the setting of its properties:

– IP AddressIt is the IP address of the NE.Each NE must have an univocal IP address.

– DisabledWhen the operator selects Disabled, the system sets to “disabled” the startingstatus of the NE. A disabled NE is marked on the map by an icon with a small crossand with a different colour.



– ProxyIt is possible to activate the proxy management (it is disabled by default), selectingUse Proxy and inserting the IP address and the port of the proxy server. The portmust have a number higher than zero and it depends on the configuration of the

proxy server (usually it is 1080).

If a new map is inserted, the disabling status for the new NE is selected by default; inthis case, if the NE is enabled, the status changes are reported to every chain of maps(not to the the NEs) NE belongs to. After the insertion of a new sub-map, it is possible,through mouse, to select and to move the relevant icon on the desired point of the map.

Fig. 18 – Window for the insertion of a new NE

4.2.2.2 Sub-Map

The Sub-Map command allows to insert (main map or sub-map) a new sub-map intothe current map. After this command, the system opens the property window (see Fig.19) because the insertion of a new sub-map needs for the setting of its properties:

– NameThis is the name used to represent the sub-map into the current map.It is possible to use the same name for more sub-maps if such sub-maps do nothave the same level.

– DisabledWhen the operator select Disabled, the system sets the starting status of thesub-map to “disabled”. The sub-map status is coupled to all the objects in thesub-map itself (NE and possible sub-maps).

– Enable/Disabled IconIt is possible to specify the icon to be displayed for the sub-map according to itsenabling status. By default, a disabled sub-map is marked by means of an icon witha small cross.

The new sub-map is not associated to any background drawing. In the case of insertionin a disabled map, the disabling status for the new sub-map is selected by default. Afterthe insertion of a new sub-map, it is possible, through mouse, to select and to move therelevant icon on the desired point of the map.

If the user defines a host table, it is possible to use mnemonic acronyms insteadof the numeric IP addresses.Each mnemonic acronym has to be an univocal one.

4.2.3 Delete

The Delete command allows to delete the selected object (NE or sub-map) on the map.In case of deleting of a sub-map, all the objects in this sub-map are cancelled at thesame time (NEs and possible sub-maps). In this case, the confirmation of the commandexecution is requested (see Fig. 21).The Delete command is active only if an object (NE or sub-map) has been selected.

Fig. 20 – Confirmation window for the deleting of a sub-map

4.2.4 Background

The Background sub-menu (see Fig. 21) contents the commands to manage thebackground drawing of the current map (main map or sub-map).The files of the background drawings must be “.BMP” format files.

The commands of the Background sub-menu are deactivated, if it has been selected aNE or a sub-map.

Fig. 21 – Back ground Menu

The drawings with “.BMP” format used as map backgrounds must have acommon colour palette; or it is necessary to increase the desktop colour depth(using the “TrueColor” mode, it is possible to avoid every problem).

4.2.4.1 Insert

The Insert command (see Fig. 22) allows to insert a background drawing on the currentmap. This command is active only if the map does not have a background drawing.

Fig. 22 – Window for the Insert command of the Back ground menu

4.2.4.2 Delete

The Delete command allows to delete the background drawing on the current map. Thiscommand is active only if the map has already a background drawing.

4.2.4.3 Change

The Change command (see Fig. 23) allows to change the background drawing on thecurrent map. This command is active only if the map has already a background drawing.

Fig. 23 – Window for the Change command of the Background menu

4.2.5 Security

The Security submenu (see Fig. 25) contents the commands to configure and tomanage the map Security.The map Security has the following functions:

– it allows the map opening only to authorized users. Each user is characterized bya user class (that defines the access prerogatives) and by a password.



– it allows to memorize the NE passwords (NE Security) into the map file, to couple,for each user class, the NE passwords to a single map one. This feature allows theuser to access to the map and to its NEs with his authorizing user class and usingthe map password only.

Three different user classes are provided:

– Read only: access to the functions in reading mode only;

– Read Write: access to the functions both in reading mode and in writing one, withthe exception of the functions reserved for the Admin user class; for these functionsthe access is allowed in reading mode only.

– Admin: access to all the functions both in reading mode and in writing one.
