Retrieving Signaling Service States
Retrieving state information about your signaling services is a task that performed daily. For more
information about this task and other daily task, see the “Daily Tasks” section on page 3-1.
To retrieve information about a specific signaling service, log in to the active Cisco PGW 2200
Softswitch, start an MML session, and enter the rtrv-dest: sig_srv command:
Where sig_srv is the MML name of a signaling service.
The system returns a response like the following:
MGC-01 - Media Gateway Controller 2001-06-12 14:53:03
M RTRV
"sigsrv1:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=RCNG"
For more information on the response to this command, see the “Understanding the Signaling Service
State Information” section on page 3-10.
If the destination is in a primary service state other than IS, attempt to bring it into service, as described
in the “Setting the Service State of a Signaling Service” section on page 6-103.
Note If the rtrv-dest MML command is entered after a switchover has occurred, the state of some of
the signaling services might be listed as undefined (UND). UND is the default state for a
signaling service when the system starts. In this instance, UND states indicate that the Cisco
PGW 2200 Softswitch has not received a service state message for the associated signaling
service since the switchover occurred. No user action is required.
Retrieving Service State of C7/SS7 Links or Linksets
To retrieve the service state for an individual SS7 link, log in to the active Cisco PGW 2200 Softswitch,
start an MML session, and enter the rtrv-c7lnk: C7_linkname | c7_linksetname command:
For example, to retrieve the service state for an SS7 link called c7link1, enter the command:
rtrv-c7lnk:c7link1
The system returns a message like the following:
Media Gateway Controller 2000-03-26 20:26:18
M RTRV
"c7link1:ls01,LID=0:IS" /* Link 1 in Linkset 1 */
