Two circuit packs can be used for multimedia connections:
■ ‘‘TN787D (or later)’’
■ ‘‘TN2207/Expansion Services Module’’
TN787D (or later)
The Multimedia Interface Circuit Pack (TN787D or later and also called the
MMCH 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 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. 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 ‘‘Multimedia Call Handling (MMCH)’’ in Chapter 5, ‘‘Alarms, Errors,
and Troubleshooting’’ for MMCH troubleshooting information.
