Physical Installation
The physical components necessary to utilize MMCH capabilities include:
•
H.320 DVC systems that are BRI connected to the Avaya DEFINITY® Server.
•
Non-BRI multifunction telephones.
•
Avaya TN787 MultiMedia Interface (MMI) and TN788 Voice Conditioner (VC) boards.
•
A T.120 Extended Services Module (
ESM
) server (necessary only if you plan to do T.120 data
collaboration). Connectivity of the ESM requires an additional TN787 along with a TN2207 DS1
circuit pack.
Dual Port Desktop
Both Basic and Enhanced multimedia complexes are dual-port desktops that consist of:
•
a BRI-connected multimedia-equipped PC that supports the H.320 protocol
•
a non-BRI-connected multifunction telephone set.
The PC and the multifunction telephone are individually wired to the Avaya DEFINITY® Server. These
two pieces of equipment can be administratively associated to form a Basic or ENHANCED multimedia
complex
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 administration on Communication Manager and may be located in
multiple port networks.
