Step 4 If the primary service state is not IS for any of the CICs, or if a CIC is blocked, check your
alarms-retrieval MML session for bearer-related alarms. The “Monitoring the Alarms Status” section on
page 3-7 describes the method for setting up an alarms-retrieval MML session.
If a bearer channel-related alarm appears, you can determine the appropriate course of action by
searching for the corrective actions for that alarm in the “Alarm Troubleshooting Procedures” section on
page 6-4. If the alarm is not in that section, corrective action is not required. More information on the
alarm can be found in Cisco PGW 2200 Softswitch Release 9 Messages Reference.
Understanding CIC States
The elements of the output from the rtrv-cic MML command are described in the following paragraphs.
Circuit Identification
The output of this command identifies the MML name of the associated signaling channel and the
number for each CIC.
Primary Service State
The PST field shows the current primary service state of the CIC. Table 3-4 lists the valid primary
service state values.
Call State
The CALL field identifies the current call state of each CIC. After a call is initiated, a circuit does not
return to the Idle (available) state until all related release signaling is satisfactorily completed (the
correct release sequence). In and Out call states indicate that the CIC is not available for new calls.
Table 3-5 describes the various call states.
Table 3-4 CIC Primary Service States
Link State ID Link State Description
IS In-service The traffic channel or CIC is IS and fully operational. This state
is its normal operating state.
OOS Out-of-service The traffic channel or CIC is OOS from the remote end. The
system is actively trying to restore the link. Individual CICs can
be OOS even if the destination is IS, because of signaling events
such as Q.931 service messages.
Table 3-5 CIC Call States
State Description
In Incoming call is in progress. Bearer channel is not available for a new call.
Out Outgoing call is in progress. Bearer channel is not available for a new call.
Idle Circuit is available for use.
