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 4, ‘‘Alarms, Errors,
and Troubleshooting’’ for MMCH troubleshooting information.
