Troubleshooting 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 Media Server 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
Media Server system.
Before troubleshooting any problems associated with the 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.
