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 Avaya DEFINITY Server. 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. Avaya MultiVantage 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 MMCH, there should only be one conference available to select.
4. The user must now use the PC’s GUI to begin application sharing. The
method for beginning application sharing or file transfer is different for
each H.320 multimedia application. One of the H.320 DVC systems
activates data sharing from the H.320 DVC vendor provided GUI. See your
H.320 DVC system documentation for details.
5. The same H.320 DVC system as in step 4, opens an application,
whiteboard, etc. to share and the image of the application is displayed on
all H.320 DVC systems in the conference.
For details on how multiple users may control the shared application, see
the vendor provided documentation for your specific H.320 DVC system.
