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 DEFINITY ECS.
■ Non-BRI multifunction telephones.
■ DEFINITY 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 DEFINITY
ECS. 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.
