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 screen. 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 screen 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 screen 
under the Minimum Maintenance Threshold section and in the MMIs field), a MMI-LEV error is 
logged. If this outage continues for 15 minutes, a MAJOR alarm is raised.

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 busyout board or busyout port, 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.

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 by failing the Archangel sanity scan test or is 
removed from service physically by removing the circuit pack from the carrier, no error/alarm is 
raised against either the MMI-BD or the MMI-PT MOs. Therefore, if a MMI-LEV error/alarm
