n ActionStep

10 View the existing congestion control parameters for all carriers equipped for the BTS by entering

the following command at the prompt:

omc–000000>DISPLAY BTS–<bts#> CONGESTCONF

Observe the following typical system display response for a BTS:

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 all of the sector paging channels at the BTS.

11 Enter the following command at the prompt using the applicable BTS number:

omc–000000>EDIT BTS –<bts#> 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 will force the Global Service Redirect Message to be broadcast on all of the sector paging

channels at the BTS.)

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 BTS and onto a different system or CDMA carrier

channel. This effectively shuts down the BTS.

12 Verify that the CONGESTCONF globalredirect is enabled for each carrier at the BTS by

entering the following command at the prompt:

omc–000000>DISPLAY BTS–<bts#> CONGESTCONF

Observe the following typical system display response for a BTS:

CARRIER NEWCALL REG AGG

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

1–1–1 1 ENABLE ENABLE ENABLE DISABLE ENABLE

13 Display the status of all devices at the BTS by entering the following command at the prompt:

omc–000000>DISPLAY BTS–<bts#> STATUS

Record the system response for all devices that are OOS_AUTOMATIC. This information will be

used for later reference when restoring site signaling operations.
