Functional description

Figure 1. Ethernet Interface Unit (EIU) installed in a subrack

2.1 Overview

Ethernet Interface Unit (EIU) is designed to enhance flexibility of theDynanet product family. The EIU unit provides direct Ethernet interfacesfor customer data applications. One Dynanet node can offer POTS, ISDNand data connections on the same E1 transmission link.


Operating manual

The unit operates as a transparent bridge and it provides three plus threeindependent 10/100BASE-T Ethernet interfaces. EIU combines sixEthernet ports over the TDM netwok and all protocols are simply passedthrough from the LAN side to the TDM netwok. EIU can be connected toPCs, hubs and other LAN equipment by using the cabling with an RJ45connector. LAN interfaces can be individually configured to the 10BASE-Tor 100BASE-TX modes, full or half duplex. Ports can also be set to autonegotiation mode, and then best possible mode is automatically selected.All LAN ports have auto MDI/MDX capability to detect transmit and receivedirection. Hence cross-over cables are not needed.

The EIU has intergrated cable testing to analyse Ethernet cabling. Withthis function, the length of Ethernet cable can be measured and shortcircuits of cabling can be detected.

Ethernet packets are carried over the time-division multiplexing (TDM)network in the high-level data link control protocol (HDLC) frame. EIUoffers data rates n x 64 kbit/s (n=1...31) from 64 kbit/s up to 1984 kbit/sover a TDM link. EIU learns automatically medium access control (MAC)addresses on the LAN it is connected to and forwards only the frames thatare destined to another LAN. EIU can store up to 1024 MAC addresses.Maximum transfer unit is 1536 bytes and VLAN (IEEE802.1Q) taggedframes are forwarded transparently.

The unit is connected to the Dynanet bus and it can be installed into allDynanet cartridges and subracks. EIU needs a master unit which performsmultiplexing of data to the TDM network. As a master unit can operate DM2, DM 2+, DB 2, DN 2, or ACM2.

The 21133.03 unit has two integrated Ethernet switches. Both switcheshave three local 10/100BASE-T interfaces and one port is connected tothe TDM.

Switches can be connected together with a digital cross-connection. In thiscase, there are six local interfaces and two ports are connected to theTDM.

The EIU unit has the following features:

. fully compatible with other Dynanet products

. 3 + 3 10/100BASE-T Ethernet interfaces, IEEE 802.3

. transparent bridging with the MAC level filtering

. transmission rates n x 64 kbit/s, the maximum rate 1984 kbit/s

. management via the master unit's Q1 bus




. Compatible with ET bridge adapter of DNT modem.

. two integrated Ethernet switches

. digital cross-connection.

. integrated cable testing

Operating manual

In the figure below there is a point-to-point bridge where two LANs arelocated in separate sites. These sites are connected together over theTDM network using EIU units. There could be at one EIU one to sixEthernet ports connected to the one TDM channel or two separatechannels with one to three Ethernet ports. Every Ethernet port can beindividually configured to 10BASE to 100BASE modes. EIU makes rateadaptation between 10BASE and 100BASE transmission speeds.

Figure 3. A point-to-point bridge using EIUs

To configure multipoint transmission, allocate one channel to the directionA and the other to the direction B. There has to be same amount of timeslots to both directions to ensure proper operation. Then enable theinternal cross-connection to obtain six local ports and two ports connectedto the TDM. On this configuration is digital branching needed, for exampleDB2 or DN2 to route TDM time slots to proper direction.

The EIU unit can be installed with other Dynacard units, and the samenode can offer direct data and voice applications. Ethernet over TDM timeslots can be freely mixed with voice and other data time slots and they allcan be transmitted via the same E1 link (see the following figure). The EIUunit uses the high-level data link control protocol (HDLC) framingaccording the RFC 1662 in the TDM side of link and it is compatible withDNT2M and the ET bridge interfaces

The EIU unit can also operate as local switch 6 port Ethernet switch. Localswitch mode can be configured to two individually three port Ethernetswitched, if internal cross connection is disabled. On the local switch modeconnection to the TDM is not needed and all transmission is between localEthernet ports. In local switch mode Dynanet master units is still neededand configuration is made via Q1 connection of master unit.

The EIU unit can be configured to stand alone switch mode when masterunit is not needed and only battery voltage is received from Dynanetsubrack. On stand alone mode EIU operates as a six port Ethernet switch.All ports are in 10/100BASE auto negotiation mode, auto MDI/MDX isenabled and yellow LED is turned on. Stand alone mode can selected byNR1S stapping.

3.1 Introduction

The Ethernet Interface Unit is installed into a NDM equipment subrack.The NDM subrack product documentation explains the connection ofcentral battery voltages and rack alarms to the subracks, routing of signalcables, connection of groundings, as well as installation planning and workorder.

EIU units are ready to operate after their installation into a subrack and theconnection of signal cables.

Instructions for installation of the equipment into subracks and cabling ofsignal interfaces are given below.

Caution

Always use a wrist grounding or other such protection when handling aplug-in unit removed from its package.



Installation

3.2 Mounting units into cartridges and subracks

3.2.1 Power supply

When the unit is inserted into its location in the subrack, the central batteryvoltage is connected through the motherboard of the subrack and backconnector PB1 of the unit. At the same time, the unit is also grounded tothe subrack.

Figure 7. Back connector PB1

3.2.2 Equipping

Connectors of the subrack motherboards and back connectors of the unitsare standardised so that voltages and rack alarm signals conveyed bythem are always located in the same place. Due to this, no unit location inthe subrack is reserved for a particular set of equipment.

The unit can be installed in any NDM subrack equipped with a master unitand it can be inserted in any unit location. The subrack can also houseother equipment of Dynanet equipment generation.

3.3 Signal interfaces and cabling

The cable type is S/FTP Category 5 (CAT5) and the maximum cablelength is 100 m. Connectors are shielded 8-pin modular connectors (RJ45type).

Figure Pin order of the interface connectors on 21133.03 presents the pinorder of the interface connectors on the 21133.03 unit. Figure RJ45connector shows the RJ45 connector.

You can check correctness of the cabling at the link integrity LED.

Polarity of the RD- and RD+ signals is automatically corrected.

Auto MDI/MDX sets transmit and receive to correct pins of the RJ45connector. EIU can be connected to the network adapter and externetswitch or hub with the same cabling.

3.4 Grounding of shielded cables

EMC requirements are only met when a shielded twisted pair cable (S/FTP) is used.

This is the recommended grounding method for all shielded pair cables.

3.4.1 Stripping of cables

Strip the sheath at the grounding point only. For the correct strippingdimensions, see Figure Stripping dimensions.

Begin by making transverse incisions at the marked places without cuttingall the way through the cable's outer insulation. Then join the transverseincisions by a longitudinal incision which should cut through the outerinsulation but not damage the cable's inner parts.

Installation

You can now easily remove the needed length of the outer insulation bygrabbing the edge of the longitudinal incision and turning it around thecable. Depending on the cable's structure, the protective metal layer maybe under a protective band which must also be removed.

Figure 13. Stripping dimensions

Stripping dimensions are as follows:

. Dimension 'a' is 90 mm, length between the connector and thestripped part of the cable.

. Dimension 'b' is 40 mm, length of the stripped part.

3.4.2 Grounding of the cables

Ground the cables by fastening each of them with two cable ties to thegrounding rail with their conductive grounding screen and/or groundingconductor attached to the EMC gasket.

One of the cable ties is fastened around the unstripped part of the cableand the other around the grounding screen. When fastening the lattercable tie, be careful not to damage the grounding screen. The lock of thecable tie is placed on top of the cable, not on the side (see FigureGrounding of cables to the grounding rail).

a b


Operating manual

Figure 14. Grounding of cables to the grounding rail

The cable's grounding screen must be in good electrical contact with theconductive EMC gaskets of the cable grounding assemblies. Properelectrical contact must be ensured, for example by measuring theresistance. During the measurement, cable ends must not be in contactwith anything. The resistance - as measured from the cable screen at oneconnector to the body of the subrack - must be less than 1.0 ohms.

4.1 Introduction

4.1.1 General

Operation of the Ethernet Interface Unit is controlled via the serviceinterface of a master unit using the Service Terminal. Through thisinterface, equipment state and alarm data are read, controls and settingsare given, loopbacks are set, and so on.

If service interfaces have been connected into a bus and the buses havebeen further connected into a service network by means of a data channel,all equipment connected to the bus or network can be remote-controlledfrom one point using the Service Terminal or a network managementsystem.

Chapter Service Menu Reference describes the service menus obtainedfrom the equipment and their use. For the Service Terminal, there is aseparate Operating Manual.



Operation

The EIU unit is ready to operate after its installation into a subrackequipped with a master unit and connection of signal cables. Beforecommissioning, however, identifications and settings should be checked,required changes in the factory settings made, and statistics and errorcounters reset.

Commissioning measurements are not necessary.

4.1.2 Start-up of the unit

1. Insert the EIU unit, the master unit and any other units that may beincluded in the configuration in a Dynanet subrack.

2. Connect the Service Terminal to the service connector of the masterand establish a connection to the equipment (connection cables notconnected):

3. The green LED is lit to indicate that a connection from the ServiceTerminal to the equipment has been established.

4.2 Maintenance

The equipment does not require scheduled maintenance. Maintenance isneeded only when the equipment indicates with alarms that there is a fault.Accurate data concerning the equipment state and nature of the fault areobtained via the Service Terminal.

Additional data on the condition of the equipment and on signal quality areobtained from measurements and statistics made by the equipment itself.Measurement results and statistics are read with the Service Terminal.

The Service Terminal can also be used to carry out tests and set onloopbacks possibly required in fault location.

Operating manual

Interpretation of alarms at equipment level

When the red service LED is lit, there is a serious fault in the equipmentand the equipment usually has to be replaced with a new one. The redservice LED, red rack alarm lamp and programmable alarm output PA1 areactivated by means of an external auxiliary voltage.

When the yellow service LED is lit, the signal received by the equipmentmay be faulty. The alarm can also be triggered by a controlled servicefunction performed in the equipment (for example, loopback or forcedindication). The equipment indicating the alarm is not necessarily faulty;alternatively, the fault may be in the far-end equipment or in the signalcabling.

The green service LED is lit when the equipment is connected to theService Terminal.

Interpretation of alarms at unit level

Operation of the unit's logic section can be superficially checked byobserving the states of the unit's service LEDs.

. The red service LED is lit when the unit is faulty.

Tip

If there is a power supply fault, the red LED is lit even if the fault wereoutside the unit.

. The yellow LED is lit when the fault is somewhere else in theequipment.

. The green service LED is lit when transmission management actionsare directed to the unit via the service interface on the MUX unit.

State and fault messages

The following table describes the state and fault messages of theequipment that are obtained by the Service Terminal through the servicemenu option 1 Fault display. The rack alarm/service LED indication ineach situation is also indicated.

4.2.2 Interface status LEDs

On the EIU unit, there are six bicolour red/green interface status LEDs,one for each interfaces. These LEDs indicate the operational state of theEthernet interface. LEDs are located under every RJ-45 connector.

. Integrity

The link integrity LED indicates a good link integrity on a twisted pairport. Link integrity informs that the EIU unit's port is connected toanother Ethernet-compatible equipment and the cabling isoperational. LED is green when port is 10BASE mode and red whenport is 100BASE mode.

. LAN activity

This LED is lit when the EIU unit's port is connected to anotherEthernet-compatible equipment and the cabling is operational. ThisLED blinks when data is received or transmitted thorough port..

. Buffer

This LED function is used to indicate a buffer overflow. The EIU unitremains functional even if buffer overflows occur.


Operating manual

The buffer LED function provides an indication to the systemmanager that the traffic rate is not balanced between the LAN andWAN sides and the buffer capacity is not sufficient for the currentset-up. If this situation continues for a while, the error LED will be litall the time. After the buffer has been cleared, the error LED will beturned off.

Buffer LEDs are located bottom side of EIU near LED holder.Channel 1 buffer LED is above LED holder and channel 2 buffer LEDis below LED holder.

Access to unit

Since the EIU unit is not provided with a service interface of its own,service functions must be directed to the EIU unit via the master unit. First,select the main level menu (4...9), then 9 followed by a comma, and finallythe unit number: 4...9,9,unit. Unit numbering starts from 1 on the left. Nowthe menu of the unit concerned, below the main level, is displayed.

5.4 Ethernet Interface Unit menus

The EIU unit is controlled via the service interface in the master unit. Themain unit provides the menus related to the common section of theequipment, and via the menus offered by it, you can select a particular unitas an object. The EIU unit provides the menus required for its control.

5.4.1 Fault display

The main unit collects fault data from other units into a common faultstorage. At the initialisation stage, the main unit collects from each unit thefault-related data: faults that are active in the unit, their effect on alarmoutputs, the fault code related to each fault, the way the fault is indicated(colour of the indicator), and the name of the control block.

The main unit generates a response to the fault inquiry. This responsecontains the following information:

. equipment ID (equipment name)

. fault status

. fault data. faulty object. fault type (fault code).

Example: *02A (ABS)

MUX-2M unit 1:

. incoming 2M missing

nx64k unit 3:

. power supply fault


Operating manual

The equipment, named 02A, has alarms A, B and S active. Faultmessages come from the equipment interface 1 control block (unit 1), thefault being that the incoming 2 Mbit/s signal is missing, and from thecontrol block of the nx64k EIU unit (unit 3), the fault being a power supplyfault.

The nx64k EIU unit contains one control block and equipment interface.

Faults controlled in the EIU unit

. Power supply fault

. Forced indication

. Equipment fault

. Equipment reset

. Loop to equipment

. Buffer overflow (2 Mbit/s transmit and receiving clocks are notsynchronised)

. Installation fault
