Termination Shunt for the ISDN BRI-S/T NIM Card

ISDN BRI-S/T terminal equipment devices may be connected at random points of the cable in point-to-point or point-to-multipoint configurations. Line termination resistors must be provided at both ends of the transmit/receive lines only.

The XSR’s BRI NIM card provides an option to terminate receive as well as transmit lines using 100 Ohm resistors. Shunts are required to shorten the appropriate contacts of the terminal headers (P1, P2). Refer to “Installing Shunt/Terminal Strip” on page A-17 for directions.

Figure A-20below shows per port respective termination header locations and the orientation of the receive and transmit pairs.

Caution: The cable connecting the BRI NIM to the balun requires two additional wires to extend the chassis ground to the balun. Cables of this type are often provided by your supplier who can customize them for your needs.

Installing Shunt/Terminal Strip

To install the shunt or terminal strip, attach two dual-pin units vertically to P1 and P2 four-pin jumpers corresponding to the RJ-45 port using a balun, as shown in Figure A-20. Any other RJ-45 ports on the NIM card connected to 120-ohm lines do not require shunts.
