MMI-LEV (Multimedia Interface
Resource Level)
The Multimedia Interface Resource Level MO monitors MMI efficiency by tracking
the number of MMI ports that are in-service, and then comparing that number with
the value entered in the
MMIs
field on the System-Parameters Maintenance form.
This
MMIs
field is located under the Minimum Maintenance Threshold section.
The
MMIs
field contains the minimum number of MMI ports needed for the
Multimedia Call Handling (MMCH) feature to run efficiently and is an
administrable field. This field must contain a minimum threshold number for MMI
port capacity of between 0-128. The MMCH feature must be enabled on the
System-Parameters Customer-Options form before the
MMIs
field can be
changed to a number greater than zero. The algorithm for determining that a low
level of MMI resources exists uses the value entered in the
MMIs
field, and the
number of MMI ports that are in-service in the system.
Each MMI circuit pack contains up to 32 ports. If the number of in-service MMI
ports falls below the minimum port capacity (value entered on the System
Parameters Maintenance form under the Minimum Maintenance Threshold
section and in the
MMI
field), a MMI-LEV error is logged. If this outage continues
for 15 minutes, a MAJOR alarm is raised.
Resolving MMI-LEV Errors/Alarms
MMI ports are a key part of the MMCH feature, and any loss in the number of
ports available for use degrades the MMCH customer-defined service level.
If a MMI circuit pack or port is busied out using the busyout board or busyout
port commands, these out-of-service ports are not included in the MMI level
calculation, thus allowing a technician to busyout a MMI circuit pack for
maintenance reasons without causing a MAJOR alarm to be raised. However, if
every port on the MMI circuit pack is not made busy and the circuit pack is
removed, an alarm is raised.
NOTE:
When diagnosing a MMI-LEV problem, begin by resolving any alarms raised
against MMI-BD or MMI-PT MOs. Clearing MMI-BD or MMI-PT alarms may
clear the MMI-LEV alarm.
