Managing multimedia calling
555-233-506308 Issue 5 October 2002
Service Links are not used by Basic mode complexes.
A single number may be used to reach the Basic multimedia complex for
voice or H.320 multimedia calls.
Enhanced Mode Operation
The Enhanced multimedia complex provides a much more tightly coupled
integration of the complex voice station and H.320 DVC system. In Enhanced
Mode:
Both multimedia and voice calls must originate at the telephone set.
Voice and multimedia calls can be controlled at the telephone set.
Conferencing is spontaneous and established just like a voice-only
conference call.
There is extensive support for multimedia feature interaction. Most voice
features work the same for multimedia calls.
Service Links can be either permanent or as-needed.
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 Enhanced Services Module (ESM) server (necessary only if you
plan to do T.210 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
