The Multimedia Interface circuit pack provides a number of H.221 protocol terminations for bit
streams received from the TDM bus. The Multimedia Interface demultiplexes the H.221 bit
stream (audio, video, data, control, and indication signals) and transmits the bit streams onto
the TDM bus to be processed by the appropriate circuit packs.
Each Multimedia Interface circuit pack contains 32 separately maintained “ports,” more
commonly referred to as “resources.” MMI-PT represents one of these 32 resources. At system
boot or when the circuit pack is inserted, 32 resources are inserted into the system.
The MMI circuit pack contains 4 Digital Signal Processors (DSPs) which manage the 32
resources. These resources are directly mapped to DSPs:
All 8 resources that the circuit pack controls may be placed out of service by the failure of one of
these DSPs.
