You can map the preceding response to the circuit validation test in Step 1, as presented in the following
list:
• CctGrpCarrier—Value in this field maps to the value in the GRP field, as follows:
– 0—Equal to UNK (unknown carrier) in the GRP field.
– 1—Equal to ANL (analog carrier) in the GRP field.
– 2—Equal to DIG (digital carrier) in the GRP field.
– 3—Equal to AND (analog and diglossia carrier) in the GRP field.
• Glare—Value in this field maps to the value in the SEIZ field, as follows:
– 0 or 3—Equal to NONE (no circuit control) in the SEIZ field.
– 1—Equal to ALL (all circuit control) in the SEIZ field.
– 2—Equal to ODD (odd circuit control) in the SEIZ field when the OPC is less than the
associated DPC. Equal to EVEN (even circuit control) in the SEIZ field when the OPC is greater
than the associated DPC.
• AlarmCarrier—Value in this field maps to the value in the ALM field, as follows:
– 0—Equal to UNK (unknown) in the ALM field.
– 1—Equal to SOFT (software handling) in the ALM field.
– 2—Equal to HARD (hardware handling) in the ALM field.
• CotPercentage and ExtCOT—Values in this field maps to the value in the COT field, as follows:
– CotPercentage is undefined and ExtCOT is not set to Loop or Transponder—Equal to UNK
(unknown continuity check requirements) in the COT field.
– CotPercentage is set to any value and ExtCOT is not set to Loop or Transponder—Equal to
NONE (no continuity check requirements) in the COT field.
– CotPercentage is greater than 0 and less than 100 and ExtCOT is set to Loop or Transponder—
Equal to STAT (statistical continuity check requirements) in the COT field.
– CotPercentage is set to 100 and ExtCOT is set to Loop or Transponder—Equal to PERC (per
call continuity check requirements) in the COT field.
Step 6 Start a provisioning session as described in the “Starting a Provisioning Session” section on page 3-64.
Step 7 Modify the appropriate signaling service settings using the
prov-ed:sigsvcprop:name=” sig_svc ”, param_name =” param_value ”, param_name =” param_value ”,...
command.
Where:
• sig_svc—MML name for the affected signaling service.
• param_name—MML name for a mismatched setting.
• param_value—Correct value for a mismatched setting.
For example, to change the settings for the COT to per call and seizing (glare) to no circuit control for
the ss7dms signaling service, enter the
prov-ed:sigsvcprop:name="ss7dms",ExtCOT="Loop",
CotPercentage=”100”,GLARE="0"
command:
Step 8 If the Cisco PGW 2200 Softswitch is provisioned for a switched environment and you need to modify
the COT or seizing (glare) properties, modify the trunk group properties.
If you must modify the trunk group properties, proceed to Step 9.
If you do not need to modify the trunk group properties, proceed to Step 12.
