VC-LEV (Voice Conditioner DSP Port Level)
Enable the MMCH feature on the System-Parameters Customer-Options form
before changing th e fields.
The Voice Conditioner (VC) Port Level MO monitors VC efficiency by tracking the
number of VC ports that are in-servic e, and then comparin g that number with the
value entered in the VC field on the System-Parameters Maintenance for m. This
VCs field is located und er the Minimum Maintenance Thresholds sec tion. The
VCs field contains the minimum numb er of VC ports needed for the Multi media
Call Handling (MMCH) feature, and is an administrable field. The VCs field must
contain a number between 0 and 126, and is entered b y the system
administrator. The MMCH feature must be enabled on the System-Parameters
Customer-Options form before the VCs field can be chang ed to a number g reater
than 0. For example, administering 8 in that field means 1 circuit pack. The
algorithm for determining that a low level of VC reso ur ces exists uses th e nu mber
entered in the VCs field, and the numb er of VCs that are in-service in the system.
Each VC circuit pack c ontains 16 physical p orts: 8 ports are reserved for
VC-DSPPT ports, and the remaining 8 ports are desig nated as VC-SUMPT ports.
The 8 DSP ports are made up of 4 encod er and 4 decod er resources that encode
and decode audio formats. Thus,

one VC circuit pack is req uired for every 8

ports of MMCH port capacity

. If the number of in-service VC ports fa lls below the
MMCH port capac ity (value entered on the System-Parameters Maintenance
form under the Minimum Maintenance Thresholds sec tion

and

in the VCs

field), a
VEC-LEV error is logged. If this outage continues for 15 minutes a MAJOR alarm
is raised.

Resolving VC-LEV Errors/Alarms

VC ports are a key part of the MMCH feature, any loss in the number of ports
available for use degrad es the MMCH customer-define d service level.
If a VC circuit pack or p ort is busied out using the busyout board or busyout
port command, these out-of-servic e ports are not includ ed in the VC level
calculation, thus allowing a t echnician to busy out a VC ci rcuit pack for
maintenance reasons without causing a MAJOR alarm to be raised.
NOTE:
When diagnosing a VC-LEV problem, resolve any alarms raise d against
VC-BD or VC-DSPPT maintenance objects. Clearing VC-BD or VC-DSPPT
alarms may clear the VC-LEV alarm.
