Multimedia Call Handling (MMCH)
Expansion Services Module
An Expansion Services Module (ESM) provides T.120 data sharing capability on a
MMCH multipoint H.320 video conference. Each conference participant must
have endpoints administered and a personal computer with the H.320 video
application installed. The S8700 Multi-Connect system must have the expansion
service module installed.

CAUTION:
The TN2207 circuit pack is the only pack allowing connection of an ESM to a
S8700 Multi-Connect system.
Troubleshooting
Before troubleshooting any problems associated with the S8700 Multi-Connect
MMCH, always be sure that the endpoint is operating correctly (audio, video, and
data) by making point-to-point test calls. If possible, make the test calls over the
network to test the connectivity and routing of network calls from the endpoint.
This eliminates problems such as disconnected audio or video cables and
network troubles.
