1 Overview

1.1 Introduction

This document describes how to change the synchronization mode for theA9130 MFS Evolution.

The two possible synchronization modes are:

autonomous, where each GP is synchronized from the TC or the SGSN

through a PCM.

centralized, where all GP boards are synchronized from only two fixed

sources (TC or SGSN). These fixed sources are defined when the first GP

is configured, for the whole MFS.

When changing the synchronization, the MFS must be running in configurationmode. The synchronization mode is global on the MFS, either autonomousor centralized.

1.2 PrerequisitesIMT Terminal, configured according to A9130 MFS Evolution IMT User Guide(3BK 20873 AAAA PCZZA).

The MFS must be operational and running, with both stations in site mode.

1.3 Scheduling

1.3.1 Human resources

1 operator on terminal.

1.3.2 Duration

1h -1h 30 minutes - depending on MFS - IMT connection.

1.4 Telecom / Supervision Outage

1.4.1 Telecom (GSM Traffic)

None.

1.4.2 GPRSThe GPRS is lost when stations are relaunched in site mode after executing

mfssetup, until the all the links (BSC-MFS, MFS-TC, MFS-SGSN) arerecreated and aligned. The GPRS outage is less than 30 minutes.

1.4.3 Supervision

The supervision is lost when the active station is restarted in configurationmode. The supervision outage is finished when the active station is relaunchedagain in site mode.

2 Procedure

2.2 Change the Synchronization Mode

Perform the following steps in order to change the synchronization mode:

1. Open connections (telnet, putty) on the two stations, from the DOScommand mode:

telnet 172.17.3.3, for Station Atelnet 172.17.3.4, for Station B

Enter root username and password.

2. Determine which is the active station on the MFS, with the command:

#ps -edf | grep mfs

The active station has the BckpRstr and PatchSrv processes running,the stand-by station not.

3. Perform on the stand-by station:

# /usr/mfs/bin/mfs_stop_tomas

Confirm the reboot with y.

4. Start the active station in configuration mode:

# /usr/mfs/bin/mfs_start_tomas -conf

Confirm the reboot with y.

5. After rebooting, both stations become unavailable for a while. Try to connectboth of them after some minutes, with telnet.

6. Enter root username and password, when stations are available again. The station starts in configuration mode.

7. Check on the active station when rebooting in configuration mode iscomplete:

# ps -edf |grep nectar

The reboot is complete when UP_GP_TCP process appears as launched.
