Two circuit packs can be used for multimedia connections:
TN787D (or later)
The Multimedia Interface circuit pack (TN787D or later, 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 de multiplexes 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 
on page 1669 for maintenance of these resources.
The MMI circuit pack contains 4 digital signal processors that manage the 32 resources.
