n ActionStep

10 View the existing congestion control parameters for all carriers equipped for the applicable sector

by entering the following command at the prompt:

omc–000000>DISPLAY SECTOR–<bts#>–<sector#> CONGESTCONF

Observe the following typical system display response for sector 2:

CARRIER NEWCALL REG AGG

(bts#–sector#–carrier#) SET ALARMFLAG ALARMFLAG ALARMFLAG ANALOGREDIRECT GLOBALREDIRECT

1–1–1 1 ENABLE ENABLE ENABLE DISABLE DISABLE

NOTE

In this step, you will change the value of the Global Service Redirection Flag

(GLOBALREDIRECT) in the congestion control parameters so that the Global Service Redirect

Message is broadcast on the sector paging channel.

11 Enter the following command at the prompt:

omc–000000>EDIT SECTOR–<bts#>–<sector#> CONGESTCONF !

The system prompts you to enter each control parameter value one at a time. Skip through the

prompts until you get to the following:

<globalredirect> , enter ENABLE

(This forces the Global Service Redirect Message to be broadcast on the sector paging channel.)

The system displays the values of the control parameters. Verify that only the

GLOBALREDIRECT value changed.

omc–000000>Accept [yes/no]?

Enter Y to accept the change.

Now the Global Service Redirection Message is sent over the sector paging channels. All

subscribers are redirected away from the sector and onto a different system. This effectively shuts

down the sector.

12 Verify that the CONGESTCONF globalredirect is enabled for each carrier on the sector by

entering the following command at the prompt:

omc–000000>DISPLAY SECTOR–<bts#>–<sector#> CONGESTCONF

Observe the following typical system display response for sector 2:

CARRIER NEWCALL REG AGG

(bts#–sector#–carrier#) SET ALARMFLAG ALARMFLAG ALARMFLAG ANALOGREDIRECT GLOBALREDIRECT

1–1–1 1 ENABLE ENABLE ENABLE DISABLE ENABLE
