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.

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."
