Chapter 3 Cisco PGW 2200 Softswitch Platform Operations
Regular Operations
When the Cisco PGW 2200 Softswitch software is configured for signaling, the system returns a
response like the following:
Media Gateway Controller - MGC-67 2000-04-05 08:08:12
M RTRV
"c7s-1:CIC=1,PST=IS,CALL=IDLE,BLK=NONE"
"c7s-1:CIC=2,PST=IS,CALL=IDLE,BLK=NONE"
"c7s-1:CIC=3,PST=IS,CALL=IDLE,BLK=NONE"
"c7s-1:CIC=4,PST=IS,CALL=IN,BLK=NONE"
"c7s-1:CIC=5,PST=IS,CALL=IN,BLK=NONE"
"c7s-1:CIC=6,PST=IS,CALL=IN,BLK=NONE"
"c7s-1:CIC=7,PST=IS,CALL=IN,BLK=NONE"
"c7s-1:CIC=8,PST=IS,CALL=IN,BLK=NONE"
"c7s-1:CIC=9,PST=IS,CALL=IN,BLK=NONE"
When the Cisco PGW 2200 Softswitch software is configured for call control, the system returns a
response like the following:
Media Gateway Controller - MGC-04 2000-04-05 08:05:54
M RTRV
"c7s-1:CIC=1,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"
"c7s-1:CIC=2,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"
"c7s-1:CIC=3,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"
"c7s-1:CIC=4,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"
"c7s-1:CIC=5,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"
"c7s-1:CIC=6,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"
"c7s-1:CIC=7,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"
"c7s-1:CIC=8,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"
"c7s-1:CIC=9,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"
Note An explanation of the fields in the response can be found in the “Understanding CIC States”
section on page 3-16.
Step 2 Repeat Step 1 on the standby Cisco PGW 2200 Softswitch.
Step 3 Verify that the CICs in both systems are in sync and show the same status.
Calls in progress should say CALL=IN for both systems.
If necessary, you can force the active Cisco PGW 2200 Softswitch to do a maintenance switchover (see
the “Performing a Manual Switchover” section on page 3-96) and repeat the preceding procedure for that
system.
Caution Switchover operations cause the loss of all SS7 messages that are transmitted to the Cisco PGW 2200
Softswitch for approximately 3 seconds. This switchover affects unstable in-progress calls as well as
new calls. Stable in-progress calls are not affected.
Retrieving the States of Bearers Held By a Media Gateway
You can retrieve the states of bearer channels being held by a media gateway. To retrieve the state of a
group of bearer channels that are associated with one or more signaling destinations that are being held
by a media gateway, log in to the active Cisco PGW 2200 Softswitch, start an MML session, and enter
the rtrv-tc-held:sig_dest| &sign_dest...command:
