A conference can have only one People + Content setting. What you select here
determines the setting to be used for all participants in the conference.
Endpoints in the conference that do not support the selected method will
connect with either video (if they connect via IP) or audio only (if they connect
via ISDN).
The available settings include:
• N one. Select "None" when dual-streams of data are not required.
• Peopl e+C ont ent . This Polycom proprietary technology works with most
Polycom endpoints.
• Peopl e and C ont ent VO . This Polycom proprietary technology works
mainly with PictureTel endpoints. Select this option when working with
older endpoints.
• Vi sual C oncer t PC . This is PC-based software available with Polycom
ViewStation MP/512/SP/323.
• Vi sual C oncer t FX. This is a hardware solution available with Polycom
ViewStation FX/EX and VS4000.
• H 320 D uo Vi deo. The dual stream mode is available with Tandberg
endpoints in which one part of the conference is set as the videoconference
and the other as the presentation conference. This selection supports both
IP and ISDN.
ReadiManager 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
