The MMCH feature must be enabled on the system-parameters customer-options
form before you can change these fields.
The Voice Conditioner (VC) Port 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 form. 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 on the System-Parameters
Customer-Options form 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 form
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.
