VC-LEV (Voice Conditioner Resource Level)
VC-LEV (Voice Conditioner Resource Level)
The MMCH feature must be enabled on the System-Parameters Customer-Options screen
before you can change these fields.
The Voice Conditioner (VC) Resource Level MO monitors VC efficiency by tracking the number
of VC ports that are in-service, and then comparing that number with the value entered in the
VC field on the System-Parameters Maintenance screen. This VCs field is located under the
Minimum Maintenance Thresholds section. The VCs field contains the minimum number of VC
ports needed for the Multimedia Call Handling (MMCH) feature, and is an administrable field.
The VCs field must contain a number between 0 and 126, and is entered by the system
administrator. The MMCH feature must be enabled in the License File and corroborated by the
System-Parameters Customer-Options screen before the VCs field can be changed to a
number greater than 0. For example, administering 8 in that field means 1 circuit pack. The
algorithm for determining that a low level of VC resources exists uses the number entered in the
VCs field, and the number of VCs that are in-service in the system.
Each VC circuit pack contains 16 physical ports: 8 ports are reserved for VC-DSPPT ports, and
the remaining 8 ports are designated as VC-SUMPT ports. The 8 DSP ports are made up of 4
encoder and 4 decoder resources that encode and decode audio formats. Thus, one VC circuit
pack is required for every 8 ports of MMCH port capacity. If the number of in-service VC ports
falls below the MMCH port capacity (value entered on the System-Parameters Maintenance
screen under the Minimum Maintenance Thresholds section 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
degrades the MMCH customer defined service level.
If a VC circuit pack or port is busied out using busyout board or busyout port, these
out-of-service ports are not included in the VC level calculation, thus allowing a technician to
busyout a VC circuit pack for maintenance reasons without causing a MAJOR alarm to be
raised.

diagnosing a VC-LEV problem, resolve any alarms raised against VC-BD
or VC-DSPPT MOs. Clearing VC-BD or VC-DSPPT alarms may clear the
VC-LEV alarm.
