Setting the Service State of a Signaling Service
To set the service state of a signaling service, perform the following steps:
Caution Use the set-dest command only while you are dynamically reconfiguring the system. Do not use the
set-dest command to take a signaling service out-of-service during a maintenance session, because all
calls associated with the specified signaling service are dropped. Instead, when you need to perform
maintenance, use the blk-cic command to block the CICs associated with the signaling service.
