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 the DEFINITY ECS 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 DEFINITY ECS 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
