Multimedia Calling
Multimedia Call Redirection to MM Endpoint
A dual port multimedia station may be a destination of call redirection features such as
call coverage, forwarding, and station hunting. The station can receive and accept full
multimedia calls or data calls converted to multimedia.
Multimedia Data Conferencing (T.120) via
ESM
The data conference is controlled by an adjunct device called an Expansion Services
Module (ESM). The Expansion Services Module is used to terminate T.120 protocols
[including Generalized Conference Call (GCC), a protocol standard for data conference
control] and provide data conference control and data distribution. The MultiMedia
Interface circuit pack, TN787, is used to rate adapt T.120 data to/from the ESM.
Multimedia Hold, Conference, Transfer, and
Drop
Station users have the ability to activate hold, conference, transfer, or drop on multimedia
calls. Multimedia endpoints and voice-only stations may participate in the same
conference.
Multimedia Multiple-Port Network
DEFINITY ECS supports the equivalent of 580 Basic mode complexes operating at 6CCS
traffic level. All enhanced mode complexes operate with soft-mode service links since the
use of hard-mode service links reduces capacities. G3si limits are 1/3 to 1/2 of the G3r
limits, depending on memory limitations and port network limitations.
Multiple Call Appearances
The dual port multimedia station provides multiple call appearances, each representing a
multimedia call or a voice call.
