System Descriptions

The Polycom ViewStation EX and ViewStation FX systems are 
set-top videoconferencing systems designed for conference rooms. 
The Polycom VS4000 system is a rack-mounted videoconferencing 
system designed for large conference rooms or board rooms. These 
systems may be purchased with the following optional network 
interface modules:

❑

Quad BRI : allows up to four ISDN lines to be multiplexed 
together to create a higher-bandwidth connection to the far-site 
device. Each ISDN line adds 128 Kbps to the available data rate.

❑

V.35/RS-449/RS-530: supports V.35, RS-449, and RS-530 
protocols, depending on the cable used. This interface module 
allows you to connect the system to third-party network 
interfaces.

In addition, a PRI network interface module is available with the 
ViewStation FX and VS4000 systems. This module allows you to 
make video calls over ISDN T1 and E1 lines.
