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 a maximum of 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 busy out a MMI circuit pack for
maintenance reasons without causing a MAJOR alarm to be raised. However, if
all of the ports on the MMI circuit pack are 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 maintenance objects. Clearing MMI-BD
or MMI-PT alarms may clear the MMI-LEV alarm.
The MMI circuit pack is maintained by the software like the Tone Detector circuit
pack, which can be removed and reinserted in any port board slot without
administration. Similarly, if a MMI circuit pack is removed from service logically
