The following paragraphs provide technical information about the
Quad BRI network interface module available with the
ViewStation EX, ViewStation FX, and VS4000 systems.
If you do not connect the system to an internal telephone system
(PBX), you must use a network termination (NT-1) device between
the Quad BRI and the ISDN connection at the wall outlet.
Outside the United States or Canada, service providers or public
telephone utilities generally provide the NT-1 device.
Table 2-13 shows the indicator lamp (LED) activity on the Quad BRI
network interface module.
