Abstract: This document contains the ESB:R6A SW upgradation procedure for Minilink High Capacity

1 INTRODUCTION

1.1 New Features built into ESB : R6A

Support of SUN JVM (Java Virtual Machine).The java virtual machine by sun is supported from R6A on being the minimum revision for Sun JVM is 1.4.2 , the JVM from Microsoft continues to be supported as well. The 64 kbps V.11 service channel setting in co/contra directional is now SW selectable. MMU 155/64 QAM is supported. The TRU red LEDcan be configured to report equipment severity. Support of Stub area configuration.In order to reduce the link state database size inside an area (thus reducing the memory requirements of the routers within that area).The area can be configured as a stub.External routes are not allowed to be flooded in a stub area.As a consequence routing from these areas to an external route is based on a default route.Virtual link to connect an OSPF area to a remote backbone. The terminal can store upto 300 windows that can be shared between the 15 min and 24hrs performance monitoring history. ITU G.826 and ETSI EN 301 129 performance data graphical indicationIt is now possible to check whether the software running on the slave units (MMU ,RAU) is aligned with the baseline present on the TRU1.2 Other additional features of ESB:R6A

TRU unit fail (LOS from MMU).If TRU from the far end is extracted it no longer results in an activated TRU unit fail alarm at the near end. Improvement in routing table handling.Optimization in the management of routing lines inside the routing table.2 PREREQUISITES

The ESB R6A has a limitation that in order to load the sw both ends of the hop must be up and running.

The SW upgradation should be done during low traffic hours as the procedure is traffic affecting.

3 GETTING STARTED

3.1 System Requirements

Pentium 133 Mhz processor or faster.

128 Mb RAM or more (256Mb is recommended)

20 Mb or more disk space is required.

800x600 monitor resolution .

CD-ROM drive.

One unused serial port.

A network card with one 10 BASE-T port.

One of the following OS

-Microsoft Windows 2000.

-Microsoft Windows XP.

Microsoft Internet Explorer with version 5.0

One of the following JVMs

-Microsoft Virtual Machine 5.0.0.3802

-SUN Java 2 Runtime Environment, SE v1.4.2_08.

3.2 Installing Software

To use your PC for downloading SW to Minilink-High Capacity terminals the

following SW must be installed on the Pc hard disk drive.

softwaredescription

Software DatadaseA database with available sw versions for different units.

Software Package MakerA unit that builds the specific sw from the sw available in the database.

TFTP ServerAn application used to transfer sw packages from the PC to the TRU

Note: The MINI-LINK HC LCT runs as an applet in the web browser on the PC. The applet with a revision higher or equal to R6A runs both on Microsoft and Sun Java Virtual Machines.Microsoft will support its JVM until December 31, 2007. For this reason it is highly recommended to start using Suns JVM as soon as possible. The Sun JVM also features that the applet is automatically saved in the JVM cache, thus providing a faster connection to the MINI-LINK

3.3 Starting for the first time.

3.3.1 Creating a dial up connection to the TRU

Creating a dial-up connection means that you create a default dial-up

connection to the TRU.

Note: Since the communication between the LCT and the equipment is based

on TCP/IP, the LCT uses the standard Windows way of connecting to

remote machines (a serial TCP/IP connection).

The procedures for doing this are different for different versions of Microsoft

Windows.

4 PREPARING THE LOCAL CRAFT TERMINAL(LCT)

This section contains information on some particular parts that are necessary to

be aware of while using the LCT for setting up or modifying the High Capacity

terminal.

4.1 Special Elements

If, for some reason, the MINI-LINK HC LCT stops working and nothing else

helps to start the LCT again, there is a reset button on the TRU that can be

used to force the LCT to restart.

Note that the LCT Reset button should not be used under normal conditions. If

the LCT stops responding, see Section 4.3.5 on page 43 for more information.

4.2 User preference settings

The design of the embedded LCT is such that no general or individual user

preference settings are necessary, they are automatically handled by the

LCT as needed.

Note that the person using the PC must have administrator rights on the PC,

otherwise the applet cannot write and store its information.

4.3 Trouble Shooting

The following information can be of use when trying to correct problems with

the MINI-LINK HC terminal.

Problem Remedy

MMU/Radio matching Section 4.3.1

Single or Multi mode Cable Section 4.3.2

High or Normal Laser Power Section 4.3.3

IP addressing Section 4.3.4 on page

4.3.1 MMU Radio Matching

Not all radios are suitable to work with both MMU 16 and MMU 128. This

depends on the RAU frequency band and the hardware version of the MMU

unit. If a wrong pair (MMU/RAU) has been installed in the AMM, the MMU is

reported in mismatch status in the LCT window. More information can be found

in the MINI-LINK HC Indoor Installation Manual.

4.3.2 Single or multimode cable

External optical traffic shall always be connected to the TRU using a

single-mode fiber, otherwise the LOFL2R alarm can appear, and traffic is

disrupted.

4.3.3 High or normal laser power

The system complies with optical short-haul interface S.11, as reported in

G.957. When connecting to a long-haul transmitter, check that the received

power is within the range -8 to -25 dBm, otherwise the performance is not

guaranteed.

A problem with excessive received power can be resolved by using an optical

attenuator.

4.3.4 IP addressing

When the LCT is connected through RS-232, the applet automatically

configures the routing tables to access both ends of the hop, provided that a

Point-to-Point Protocol (PPP) is established over the hop.

If two LCTs are connected on the two sides at the same time, be aware of that

they must be configured with different IP addresses.

42 1/1553-CXP 901 228 Uen H 2005-08-264.3.5 LCT Reset button

The LCT Reset button should not be used under normal conditions, only if theLCT stops responding all together

If the LCT stops responding it may be so that the applet running in the PC has

stopped working. To replace the faulty applet with a new one, do as follows:

1. Switch the LCT Off and On again.

2. Check if the LCT is able to establish a connection to the MINI-LINK HC

radio terminal.

3. If not, use a pin (a lead, a paper clip or similar object without a sharp tip) to

press the LCT reset button A on the TRU for about 2 seconds and release it.

The browser window will be turned off and then on again to start a new applet

session.

Note: This operation does not affect the traffic.

5 SW UPGRADATION

5.1.1 Installation of upgrade tools

First of all install the upgrade related tools into the LCT which can be downloaded from an ERICSSON internal link which can be accessed after the approval of an ELS Engineer

5.1.2 Installing ESB R6A into the LCT

After installation of the upgrade tools a new directory Minilink-Ptp High Capacity In the following path C:/Program Files/ Minilink-Ptp High Capacity .

The minilink ptp high capacity directory is so structured

Copy R6A Baseline software (CXP901228_R6A) Zip file to the following

path C:/Program files/Mini-Link Ptp High Capacity/Container.

Below is a printscreen illustrating this

5.1.3 Connecting the terminal to the LCT

Copy Copies the active software to the spare memory bank.

Close Closes the window and saves any changes you have madeMMU sw activation shall take 5 seconds and RAU sw upgradation shall take 10

secs. If the hop is of 1+1 configuration it will not affect traffic.TRU sw activation will take 40 secs .This is traffic affecting as it resets the TRU.Note: When far end sw is activated communicaton will be lost with the far end and the message It is highly impossible to access the far end terminal.

But after sw is activated in the near end terminal then both the windows i.e for the near and far end are visible.

After sw upgradation the sw menu changed to sw handling and 1.5db Rx level improvement was also noticed.
