The following sections describe the operations that you can use to manage signaling channels:
Note To ensure that you are retrieving the correct service states of the signaling channels, always perform the
following retrieval procedures on the active Cisco PGW 2200 Softswitch. The current service states of
the signaling channels are maintained only on the active Cisco PGW 2200 Softswitch. If you retrieve the
service state of a signaling channel on the standby Cisco PGW 2200 Softswitch, the system always
returns a message that indicates that the links are out-of-service because of the host being in the standby
state (i.e.,
"c7link1:ls01,LID=0:OOS,STBY" /* Link 1 in Linkset 1 */). Such a message does not
indicate that the signaling channel itself is out-of-service. If a switchover occurs, the service state for each
signaling channel remains the same as the standby Cisco PGW 2200 Softswitch assumes the active role.
