MMI-LEV (Multimedia Interface Resource Level)
The Multimedia Interface Resource Level MO monitors MMI effic iency by
tracking the number of MMI p orts that are in-service, and then c omparing 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 numb er of MMI ports
needed for the Multimedia Call Hand ling (MMCH) feature to run efficiently and is
an administrable field. This field must contain a minimum threshold numb er for
MMI port capac ity 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 nu mber 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-servic e in the system.
Each MMI circuit pac k contains a maximum of 32 ports. If the numb er of
in-service MMI ports falls b elow the minimum port capac ity (value entered on the
System Parameters Maintenance form under the Minimum Maintenanc e
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 d egrades the MMCH customer-d efined service level.
If a MMI circuit pac k or port is busied out using the busyout board or busyout
port commands, these out-of-servic e ports are not included in the MMI level
calculation, thus allowing a t echnician to busy out a MMI c ircuit pack for
maintenance reasons without causing a MAJOR alarm to be raised. However, if
all of the ports on the MMI circuit p ack are not made busy and the c ircuit 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 obje cts. Clearing MMI-BD
or MMI-PT alarms may clear the MMI-LEV alarm.
The MMI circuit pack is maintain ed by the software like the Tone Detector circuit
pack, which c an be removed and reinserted in any port board slot withou t
administration. Similarly, if a MMI circuit pac k is removed from service logic ally
