Using T.120

Visual Concert FX
Hardware solution available with Polycom ViewStation FX/EX and VS4000.
H320 Duo Video
Dual stream mode available with Tandberg endpoints in which one part of the
conference is set as the video conference and the other as the presentation
conference. This selection supports both IP and ISDN.
Polycom ReadiManager LX100 allows you to define T.120 conferences, and to select
the speed for the T.120 connection. Select "None" to disable the T.120 mode.
T.120 is a standard that contains a series of protocols and specifications describing
application sharing in multi-point data communication. The following options may be
available, depending on the participant equipment and software:
Application sharing, allowing two or more conference participants to work on the
same document/application even if only one participant has the application. In
application sharing, one participant launches the application and it runs
simultaneously on all the other computers.
File transfer to all conference participants.
Chat or "Whiteboard" in which participants communicate with each other via
writing.
In all of these modes, the participants can view and hear each other.
From the T.120 drop-down box, select the speed for the T.120 connection. The higher
rates (larger numbers) enable faster data transfer rates, but reduce the bandwidth
available for the video portion of the call. In low bandwidth calls of 128 kbps, use the
smallest bandwidth numbers for the T.120 setting. Check with the IT department to
determine the best combinations for your conferences.
Notes:
Selecting this option uses T.120 resources on the bridge. It is best not to select it
unless you are sure you want to use it.
T.120 cannot be added to a conference that has already started.
