Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Resolving Bearer Channel Connection Problems
To perform a circuit validation test, complete the following steps:
Step 1 Start an MML session on the active Cisco PGW 2200 Softswitch and validate the properties for a
particular circuit identification code (CIC) using the
vld-cic: dest_pc :cic= number command.
Where:
• dest_pc—MML name for the DPC associated with the affected CIC.
• number—Trunk identification number for the affected CIC.
If the circuit validation test is passed, the system returns a message like the following:
Media Gateway Controller - MGC-01 2000-03-07 09:35:19
M RTRV
"dms100-pc:CIC=105,PASSED"
If the circuit validation test failed, the system returns a message like the following:
Media Gateway Controller - MGC-01 2000-03-07 09:35:19
M RTRV
"dms100-pc:CIC=105,FAIL"
LOC: GRP=DIG,SEIZ=EVEN,ALM=UNK,COT=NONE
LOC: TRK=1003,A_CLLI=dms1003****,Z_CLLI=na*********
REM: GRP=DIG,SEIZ=ODD,ALM=SOFT,COT=STAT
The fields in the LOC line are values that are associated with the Cisco PGW 2200 Softswitch. The fields
in the REM line are values that are associated with the far-end exchange. The following list presents the
valid values for the fields that the vld-cid command displays:
• GRP—Circuit group carrier indicator. The values in these fields should be the same in the LOC and
REM lines. The following values are valid for this field:
– UNK—Unknown circuit group carrier type
– ANL—Analog circuit group carrier type
– DIG—Digital circuit group carrier type
– AND—Analog and digital circuit group carrier type
• SIEZ—Double seizing indicator. The values for this field in the LOC line should be logically
opposite to the value for the REM line. The following values are valid for this field:
– NONE—No circuit control. When one line is set to NONE, the other should be set to ALL.
– ALL—All circuit control. When one line is set to ALL, the other should be set to NONE.
– EVEN—Even circuit control. When one line is set to EVEN, the other should be set to ODD.
– ODD—Odd circuit control. When one line is set to ODD, the other should be set to EVEN.
• ALM—Alarm carrier indicator. The values in these fields should be the same in the LOC and REM
lines. The following values are valid for this field:
– UNK—Unknown alarm carrier
– SOFT—Software alarm carrier
– HARD—Hardware alarm carrier
