The Multimedia Interface Circuit Pack (TN787D or later) p rovides a number of
H.221 protocol terminations for b it streams received from the TDM bus. The
Multimedia Interface de multiplexes the H.221 bit stream (audio, vid eo, data,
control, and indic ation signals) and transmits the b it streams onto the TDM bus
so that the appropriate c ircuit packs ca n process them.
The Multimedia Interface circ uit pack is commonly referred to as the MMI pack
for H.221 protocol termination. It is also cal led the MMCH circuit pac k. There are
32 ports (also called resourc es) on the circuit pack. See MMI-PT for maintenance
of these resources.
The MMI circuit pack c ontains 4 digital signal p rocessors that manage the 32
resources.
NOTE:
Refer to ‘‘Troubleshooting Multimedia Call Handling ( MMCH)’’ in Chapter 1,
‘‘Maintenance for csi systems’’ for MMCH troub leshooting information.
