Cables Used with the Quad BRI Network Interface Module

Installation

80
The Quad BRI network interface module requires an S/T interface.
If your site does not use an internal telephone system (PBX), you
must connect the Quad BRI module to the ISDN line(s) through a
network termination (NT-1) device, which provides the S/T
interface.
The network cables are standard CAT5 cables. If you are connecting
to a PBX, you may need a crossover cable.
To connect the Quad BRI network interface module to the
system:
1. Make sure your system is turned off.
2. Connect the peripheral side of the Quad BRI network interface
module to the system using the supplied network interface
cable. This cable is color-coded blue on one end, green on the
other.
