Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Resolving Bearer Channel Connection Problems
Note Not all SS7 variants support the querying of CICs. If you execute this command on a signaling service
that is configured for an SS7 variant that does not support the querying of CICs, the system returns an
error code, SABT, when the query operation times out.
See Cisco PGW 2200 Softswitch Release 9 MML Command Reference for more information on the
SABT error code.
Note You can configure the Cisco PGW 2200 Softswitch software to issue individual or group supervision
messages for point codes that are associated with an ISUP signaling service. ISUP signaling services
issue group supervision messages by default. If you configure an ISUP signaling service to issue
individual supervision messages, you cannot use the range option cannot with this command. You can
query CICs only one CIC number at a time for point codes that are associated with an ISUP signaling
service configured to issue individual supervision messages.
For example, to query the state of CICs 20 through 24, associated with a signaling service called ss7svc1,
enter the
query-cic:ss7svc1:cic=20,rng=4 command.
The system responds with a message like the following:
Media Gateway Controller - MGC-01 2000-01-12 15:19:51
M RTRV
"ss7svc1:CIC=20;LPST=IS;LSST=IDLE;RPST=IS;RSST=IDLE"
"ss7svc1:CIC=21;LPST=IS;LSST=IDLE;RPST=IS;RSST=IDLE"
"ss7svc1:CIC=22;LPST=IS;LSST=IDLE;RPST=IS;RSST=IDLE"
"ss7svc1:CIC=23;LPST=IS;LSST=IDLE;RPST=IS;RSST=IDLE"
"ss7svc1:CIC=24;LPST=OOS;LSST=IDLE_LOC_BLOC;RPST=IS;RSST=IDLE"
The response lists the local and remote primary and secondary states of the requested CICs. If the
response indicates that the mismatch is because of a problem on the local side, you can attempt to resolve
the state mismatch using the instructions in the “Resolving Local and Remote CIC State Mismatch”
section on page 6-131. If the response indicates that the mismatch is because of a problem on the remote
side, you must contact the personnel at the remote site to resolve the problem.
The valid values for the fields that are present in the response to this command are as follows:
• LPST and RPST—Local primary state and remote primary state
–
IS—In-Service.
–
OOS—Out-of-Service.
–
TRNS—Transient, the state is currently being changed
• LSST and RSST—Local secondary state and remote secondary state
–
N/A—Not available
–
UNEQUIPPED—Unequipped
–
IC_BUSY—Incoming is busy
–
IC_BUSY_LOC_BLOC—Incoming is busy, blocked locally
–
IC_BUSY_REM_BLOC—Incoming is busy, blocked remotely
–
IC_BUSY_BOTH_BLOC—Incoming is busy, blocked both remotely and locally
–
OG_BUSY—Outgoing is busy
–
OG_BUSY_LOC_BLOC—Outgoing is busy, blocked locally
–
OG_BUSY_REM_BLOC—Outgoing is busy, blocked remotely
