Table 10-9: Shut Down Sector Signaling Functions Procedure For a Packet BTS
n ActionStep
NOTE
SHUTDOWN and REDIRECT both prevent future calls from being originated on the targeted
resource, but only SHUTDOWN waits indefinitely for the calls to terminate. When the resource
becomes idle, SHUTDOWN automatically transitions the resource to the locked/disabled state.
14 If you redirected subscribers but do not want to use SHUTDOWN, go to step 15.
If you redirected subscribers and want to use SHUTDOWN, go to step 16.
15 Wait three minutes to allow any active calls to terminate then go to step 18.
16 Shutdown all carriers equipped for the target sector at the BTS by repeatedly entering the
following command at the prompt:
omc–000000>SHUTDOWN CARRIER–<bts#>–<sector#>–<carrier#>
Repeat this command for each sector–carrier associated with the target sector.
NOTE
When a BBX is keyed, it is in an UNLOCKED/ENABLED/ACTIVE state.
When a BBX is in an UNLOCKED/ENABLED/IDLE state, it is dekeyed and INS_STANDBY.
As long as the sector–carrier associated with the BBX is LOCKED/DISABLED/IDLE, the BBX
cannot be keyed. Also the redundant BBX does not switchover for an INS_STANDBY primary
BBX.
17 Observe that the system automatically returns a “Network Element State Change Event” message
for each carrier after it is shutdown. This message shows the old and new states for the carrier. The
CARRIER will go from UNLOCKED/ENABLED/ACTIVE to
SHUTTINGDOWN/ENABLED/ACTIVE to LOCKED/DISABLED/IDLE.
When each BTS carrier shutdown in step 16 is reported as LOCKED/DISABLED/IDLE, the
primary BBXs associated with the target sector–carrier will be reported as
UNLOCKED/ENABLED/IDLE.
If you determine that it is taking too long for carriers to shutdown and the associated primary
BBXs to transition to UNLOCKED/ENABLED/IDLE state, perform step 18 to abort the
shutdown process and LOCK/DISABLE the carriers.
18 Lock/disable all carriers equipped for the target sector at the BTS by repeatedly entering either of
the following commands at the prompt:
omc–000000>DISABLE CARRIER–<bts#>–<sector#>–<carrier#> UNC
omc–000000>LOCK CARRIER–<bts#>–<sector#>–<carrier#>
Repeat the command for each sector–carrier associated with the target sector.
