Demand test descriptions and error codes - Avaya Support

The VC circuit pack is maintained by the software similarly to the Tone Detector circuit pack.
Tone Detector circuit packs may be removed and reinserted in any port-board slot without
administration. The same rule applies to VC circuit packs. If a VC circuit pack is removed from
service logically (by failing the Archangel sanity scan test) or is removed from service physically
(by physically removing the circuit pack from the carrier), no error/alarm is raised against VC-BD
or VC-DSPPT MOs. Therefore, if a VC-LEV error/alarm exists, and none has been raised
against VC-BD or VC-DSPPT MOs, a VC circuit pack may have been removed from service
causing the VC-LEV error/alarm. To resolve a VC-LEV MAJOR alarm, restore the number of VC
ports available for service to be equal to or more than the calculated port capacity (value
entered in the VCs field).
To determine how many VC circuit packs are needed for the MMCH feature:
1. Display the System-Parameters Maintenance screen by executing display
system-parameters maintenance.
2. Locate the number listed in the Minimum Maintenance Threshold (VCs) field. The MMCH
feature requires one VC circuit pack for each four ports listed in the Minimum Maintenance
Threshold (VCs) field.
3. Divide the Minimum Maintenance Threshold value by 8 to determine the number of VC
circuit packs needed. For example, a port capacity of 12 listed in the Minimum
Maintenance Threshold (VCs) field would require 2 VC circuit packs.
4. Use list configuration to verify that the number of VC circuit packs listed agrees
with the required number of VC circuit packs (determined in step 3). If the number of VC
circuit packs listed in the step 3 differs from the calculated number, restore the number of
VC circuit packs to the correct value, in order to resolve the VC-LEV alarm.

Notes:
a. Error Type 1: the number of VC resources in the system that are in service has fallen below
the calculated minimum value. If the number of in-service VC ports falls below the MMCH
port capacity (value entered in the Minimum Maintenance Threshold VCs field on the
system parameters maintenance screen), a VEC-LEV error is logged.
