Overview

RADVision support for T.120 data sharing is facilitated by an independent, external T.120
Data Collaboration Server (RADVision DCS–100). Installed on a Windows NT Server, the
DCS–100 relieves the MCU-323 of the resource strain in processing T.120 data sharing
requests. In addition, the DCS–100 allows the MCU-323 to control access for the data
sharing application, while remaining transparent to the participants of a conference at their
terminals.

Data Share

Figure 8-1 – Connection Setup Process for T.120 Data Collaboration Server

1.

A terminal requests the opening of a data sharing session with another terminal in an
active videoconference.

2.

The MCU-323 relays the request to the DCS, notifying the server of the MCU-323
capabilities and notifying the terminal of the DCS IP address at the same time.

3.

The DCS initiates the opening of data sharing channels between the terminals.

4.

The terminals are connected in a data sharing session.
