Managing multimedia calling
272Enhanced Mode MM complex

NOTE:
If party C is another Enhanced mode complex on the same switch as
station A
, station A does not need to indicate a multimedia call prior to
dialing the new party in step 3. While A consults with C, the call will be
audio only. When A completes the conference in step 5, party C’s video will
be activated.
A multi-party video conference uses voice activated switching to determine which
parties are seen. The current speaker is seen by all other parties. The current
speaker sees the previous speaker.
Additional voice or video parties may be added by repeating these steps.
Data Collaboration
Once you have established a multi-point video conference, multi-point T.120 data
collaboration may be enabled for that call. This will allow all video parties on the
current conference to collaborate.
T.120 Data conferencing is made possible through the Expansion Services
Module (ESM) which is an adjunct to the DEFINITY ECS. Up to six parties may
participate in a single data conference, and up to 24 parties may use ESM facilities
for data collaboration at any given time.
The following steps add data sharing to a video conference:
1. Set up a multimedia conference.
2. Once a multimedia call is active, any member can initiate data
collaboration by pressing the mm-datacnf button. Or, to use the feature
access code to initiate a data conference, press the Transfer button. A
second line-appearance becomes active and you hear dial tone. Dial the
multimedia data conference feature access code. Confirmation tone is
heard and the system automatically reselects the held call appearance of the
multimedia conference. The DEFINITY ECS will select an MLP data rate
which is acceptable to all H.320 DVC systems in the current call.
If the system does not have sufficient ESM resources available for all
parties currently in the call, activation of T.120 data sharing will be denied.
The mm-datacnf status lamp will flash denial or the mm-datacnf FAC will
produce reorder.
3. Each H.320 DVC system in the conference call is joined to the data
conference. On many DVC systems, the provided GUI may prompt the
user with a dialog box, requesting the user to select a specific conference to
join. With DEFINITY MMCH, there should only be one conference
available to select.
