Installing ISDN BRI terminal

For each S or T or U-LT reference point, an eight-position

miniature unkeyed plug from the terminal equipment (TE) is

plugged into a jack connected to Norstar wiring. The pin

connections for the jack and plug are shown in the following

(jack or plug)

The last connection on any ISDN S or T extension wiring must

have terminating resistors to ensure correct timing of the

signaling circuits. Failure to install terminating resistors will

degrade performance. Terminating resistors should not be

connected on a TE which is not the last connection on the loop.

Terminating resistors are provided on terminal equipment. See

the instructions that come with your TE for information on

how to enable or disable the termination, as required.
