1 Overview

1.1 Presentation

This scenario describes how to merge a G2 TC with an 9125 TC/ 9125 TCequipped with TC STM1–IP subrack.

After this procedure, the G2 TC must be dismantled at an appropriate time.

In case it is necessary to replace E1 links with STM1 or vice versa, see E1 to STM1 Configuration or STM1 to E1 Configuration , as needed.

This scenario does not cover the upgrade of an 9125 TC with TC STM1 board.If it is the case, first perform Upgrade 9125 TC with TC STM1 board .

1.1.1 Cases

The following cases apply:

C1: LCS activated on the BSS

C2: The BSS is multi GPU.

The scenario uses the configuration management rules specific to the 9153OMC-R.

1.1.2 Options

None.

1.1.3 Restrictions

This procedure does not handle BSC or TC extension.

1.2 Preparation

1.2.1 Prerequisites

The following prerequisites apply:

The site is clean, tidy and easily reachable

The BSS is operational in release B10

If a new 9125 TC rack is needed, it must be installed and commissioned

before the operation. Note the TC rack number; it must be greater than

or equal to 5.

The generic transmission data settings for the 9125 TC are downloaded.

The newly inserted boards in an 9125 TC rack already in use are already

configured.

In the case of an X.25 connection routed through the Ater/A interface,

redundancy is mandatory.

This section describes how to merge a G2 TC into an 9125 TC.

2.3.1 Initial Checks

Note Task Description Site To do Outage

CHECK Perform an Audit Alarm State on the BSS. OMC-R 5 min. None.

CHECK View Status of Managed Objects and Alarms (TC) and print them.

OMC-R 10 min. None.

2.3.2 Change TRAU LOUDNESS Parameter

The following operations must be repeated for each BSC or TC G2 rack.

You must adjust the ’TRAU Loudness’ (up and down) parameter according tothe site requirements.


OMC-R 1 min. NoneINPUT Modify Ater TRAU Loudness to set theright value.

Note:Modifying the TRAU LOUDNESS parameterautomatically launches a programming

transmission, but you can immediately start thenext task.

22 / 32 3BK 17430 0691 RJZZA Ed.06



2 Scenario

2.3.3 Switch First Ater Mux Connection

You must take into account the following information before starting the tasksin this section:

Disconnect the first Ater Mux and the related A interfaces from the terminal

blocks of the G2 TC and then reconnect to the terminal blocks of the 9125TC on the BSC side and on the MSC side at the same time. The old SM

Adapt from the TC site (ASMC board) related to this Ater Mux is unplugged.

During this time, the MSC operator is advised to lock the CICs in order to

avoid alarms.

It is advisable to ensure GSL resource redundancy. If GSL/GPU redundancy

is not ensured, the Ater Mux carrying the GSL must belong to the second

part of the moved Ater Mux.

There is CS traffic outage when there are no more available N7s; otherwisethere is CS traffic reduction.There is GPRS outage when there are no more available GSL orNS-VC/SGSN_IP_ENDPOINT; otherwise there is GPRS reduction.

The following actions must be synchronized with the MSC in order to updatethe addresses of the reconnected Ater Mux and A Interfaces.

2.3.3.1 Declare the BSC at the 9125 TC Equipped with TC STM1-IP Subrack

This task refers to the 9125 TC equipped with TC STM1-IP subrack andbefore the merging procedure starts, it is necessary to declare the associatedBSCs in the TC-NEM.
