Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Resolving SS7 Network Related Problems
Step 1 Log in to the active Cisco PGW 2200 Softswitch, start an MML session, and enter the
set-dest:sig_srv:serv_state command.
Where:
• sig_srv—MML name of the desired signaling service.
• serv_state—Desired service state. The following service states are valid:
– IS—Places a signaling service in service.
– OOS—Takes a signaling service out of service.
Note Before you can take a NAS signaling service out of service, you must shut down the D-channel on the
associated media gateway. See the documentation for the media gateway for more information on
shutting down D-channels.
For example, to set the service state of a signaling service called sigsrv1 to IS, enter the
set-dest:sigsrv1:IS command:
Step 2 Verify that the state of the destination has changed by entering the rtrv-dest command, as described in
the Retrieving Signaling Service States, page 3-45.
Setting the Service State of an SS7 Signaling Service
To set the service state of an SS7 signaling service, perform the following steps:
Caution Use the set-spc command only while you are dynamically reconfiguring the system. Do not use the
set-spc command to take an SS7 signaling service out-of-service during a maintenance session, because
all calls associated with the specified SS7 signaling service are dropped. Instead, when you need to
perform maintenance, use the blk-cic command to block the CICs associated with the SS7 signaling
service.
Step 1 Log in to the active Cisco PGW 2200 Softswitch, start an MML session, and enter the
set-spc:ss7_srv:serv_state command.
Where:
• ss7_srv—MML name of the SS7 signaling service that you want to set.
• serv_state—Service state you want to set. The following service states are valid:
– IS—Places the SS7 signaling service in service.
– OOS—Takes the SS7 signaling service out of service.
For example, to set the service state of an SS7 signaling service called ss7srv1 to IS, enter the
set-spc:ss7srv11:IS command:
Step 2 Verify that the state of the SS7 signaling service has changed by entering the rtrv-spc CRIT command,
as described in the Retrieving the State of SS7 Signaling Services, page 3-48.
