The Multimedia Interface Circuit Pack (TN787D or later) 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 so
that the appropriate circuit packs can process them.
The Multimedia Interface circuit pack is commonly referred to as the MMI pack for
H.221 protocol termination. It is also called the MMCH circuit pack. There are 32
ports (also called resources) on the circuit pack. See MMI-PT for maintenance of
these resources.
The MMI circuit pack contains 4 digital signal processors that manage the 32
resources.
NOTE:
Refer to ‘‘Troubleshooting Multimedia Call Handling (MMCH)’’ in Chapter 1,
‘‘Maintenance for CSI systems’’ for MMCH troubleshooting information.
