Table 8-2: Procedure to Shut Down Signaling Functions
Step Action
9 View the existing congestion control parameters for all carriers equipped for the sector by entering
the following command at the prompt:
omc–000000>display sector–<bts#>–<sector#> congestconf
Observe the following typical system display response:
CARRIER NEWCALL REG AGG
(bts#–sector#–carrier#) SET ALARMFLAG ALARMFLAG ALARMFLAG ANALOGREDIRECT GLOBALREDIRECT

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.
Enter the following command at the prompt:
omc–000000>edit sector–<bts#>–<sector#> congestconf !
The system will prompt you to enter each control parameter value one at a time. Skip through the
prompts until you get to the following:
<
g
lobalredirect> , enter enable
<globalredire
c
t>
, enter enable
(This will force the Global Service Redirect Message to be broadcast on the sector paging
channel.)
The system will display 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.
11 Display the status of the MAWI at the BTS by entering the following command at the prompt:
omc–000000>display bts–<bts#> status
Observe the following typical system response for the entry of: DISPLAY BTS – 300 STATUS
