Enhanced multimedia complex
An Enhanced multimedia complex consists of a BRI-connected multimedia-equipped PC and a
non-BRI-connected multifunction telephone administered in Enhanced mode. The Enhanced multimedia
complex acts as though the PC were directly connected to the multifunction telephone. Thus, voice call
control, multimedia call control and call status are enabled at the telephone. An Enhanced multimedia
complex provides a tight integration of the voice station and H.320 DVC system.
Multimedia endpoint
The multimedia endpoint is a user's PC that has been equipped with an H.320 multimedia package. The
PC is physically connected to Avaya Communication Manager with a BRI line.
Figure 33: Enhanced MMCH service link
Enhanced mode service link
The service link is the combined hardware and software multimedia connection between the user's
multimedia endpoint and the Avaya DEFINITY® Server which terminates the H.320 protocol. The
service link provides video, data, and, optionally, voice streams to augment the capabilities of the
telephone and PC. A service link only applies to an Enhanced multimedia complex, never to a Basic
multimedia complex. The service link is administered on the station screen and can be either "permanent"
or "as-needed."
Feature Description
MMCH's two levels of functionality for a multimedia complex, Basic and Enhanced mode, are enabled
either by administration on Communication Manager or by an mm-basic feature button or FAC.
