Maintenance Objects
3-1271VC-LEV (Voice Conditioner DSP Port Level)
3
The VC circuit pack is maintained by the software similarly to the Tone Detector
circuit pack. Tone Detector circ uit packs may be removed and reinserted in any
port board slot without ad ministration. The same rule applies to VC circuit p acks.
If a VC circuit pack is removed from service logic ally (by failing the Archang el
sanity scan test) or is removed from service physically (by physically removing
the circuit pack f rom the carrier), no error/alarm is raised ag ainst VC-BD or
VC-DSPPT maintenance objects. Therefore, if a VC-LEV error/alarm exists, and
none has been raised aga inst VC-BD or VC-DSPPT maintenance objects, a VC
circuit pack may have been removed from service c ausing the VC-LEV
error/alarm. To resolve a VC-LEV MAJOR alarm, restore the number of VC ports
available for service to b e equal to or more than the calc ulated port cap acity
(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 form b y executing the
command display system-parameters maintenance.
2. Locate the number listed in the Minimum Maintenance Threshold (VCs)
field. The MMCH feature requires one VC circuit pac k 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 pac ks needed. For example, a p ort capacity of 12
listed in the Minimum Maintenance Threshold (VCs) field would require 2
VC circuit packs.
4. Use the list configuration command to verify that the number of VC
circuit packs lis ted agrees with the required n umber of VC circuit pac ks
(determined in step 3). I f the number of VC circuit pac ks listed in the step
3 differs from the calculated number, restore the number of VC circuit
packs to the correc t value, in order to resolve the VC-LEV alarm.
