ISDN Network Hardware Checklist

Quad BRI Network Interface Module

© Polycom, Inc.
Depending on your network type, you will need the following hardware:
If your ISDN network is...
BRI
PRI/T1
(commonly available in
North America)
PRI/E1
(commonly available
outside North America)
Serial
(V.35/RS-449/ RS-530)
The Quad BRI network interface module allows you to make ISDN calls using up
to four BRI lines.
In addition to the Quad BRI network interface module and the cables provided
with it, you will need an NT-1 device if your site does not use an internal telephone
system (PBX). A PBX or an NT-1 device provides the S/T interface that the Quad
BRI module requires.
