Multimedia Call Handling
Issue 5 October 2002 309555-233-506
MMCH works with any H.320 system that is fully H.320 compliant and operates
at the 2B or 128K rate.
NOTE:
If you intend to share applications among users or whiteboard capabilities,
the endpoint software you choose must also support the T.120 protocol.
The following endpoint-software packages have been tested:
■ PictureTel PCS 50 & PCS 100, Release 1.6T
■ Proshare 2.0a, 2.1
■ Zydacron Z250 Ver. 2.02, Z350 Ver. 1.2 (With Netmeeting 2.0)
MMI & VC hardware
The MMCH feature requires the use of two additional circuit packs:
■ Multi Media Interface (MMI) TN787J.
■ Voice Conditioner (VC) TN788B.
The TN787 and TN788 are service circuit packs. The TN787 supports
simultaneous operation of 16 2B H.320 calls. The TN788 supports the voice
processing for 4 H.320 endpoints.
■ These service circuit packs may be located in any Port Network.
■ These packs do not require any translations as part of their implementation.
■ The MMI and VC circuit packs are resource circuit packs akin to the Tone
Detector circuit packs.
■ These circuit packs require no switch administration and may be located in
multiple port networks.
T.120 Data Collaboration Server
The Expansion Services Module (ESM) provides T.120 data collaboration
capability on a MMCH multipoint H.320 video conference.
■ Each person in the conference who wants to participate in the data
collaboration session, must have a personal computer with an H.320 video
application that supports the T.120 protocol.
■ The Avaya DEFINITY Server must have an ESM installed.
