NOTE:
Refer to
‘‘Troubleshooting Multimedia Call Handling (MMCH)’’
in
Chapter 1,
‘‘Maintenance for CSI systems’’
for MMCH troubleshooting information.
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.
