BAI Board

The BAI board (Basic Access Interface) is required for measurements on

ISDN lines and connections. The BAI board can be fitted with up to two

interface modules depending on the purpose of application. The interface

modules establish the necessary different circuits dependent on the

interface standard.

NOTE. EN 60950, IEC 950, UL 1950: The interface boards are designed

for connecting to a telecommunication network (TNV-1 circuits); the

appropriate interfaces are provided.

The supply voltage necessary for supplying power to the terminal

equipment to be tested is supplied by a separate supply module, which is

plugged on the interface board and connected to the base module.

WARNING. High voltages may occur on the following supply connectors

and sockets: under “S

Simulation / Monitoring” with “TE A” or “TE M”,

“MON A B” or “MON M N”, “TE/NT B” or “TE/NT N”;

under “U

2B1Q

Simulation / active Monitoring” with “LT A” or “LT M”

and “NT/LT B” or “NT/LT N”.

With older front panels the following supply connectors and sockets are

concerned: “to NT”, “S-BUS MON”, “to TE(NT)”, “to LT”, “to NT(LT)”.

These older terms are marked in the following with old.
