To install a BRI Interface PCB:
1.
Set the SWn02 jumpers on the BRI PCB for either T-Bus or S-Bus.
2.
Set the SWn00 jumpers as either terminated or unterminated.
3.
Set the CNn02 jumpers to either provide power (with S-Bus) or not to supply power (with T-Bus).
4.
Plug the BRI PCB into the system cabinet.
Once the system is powered up, with normal operation, the status LED will
fl
ash fast. If trouble
was found during the self diagnostics routine, the status LED will
fl
ash slow.
Once connected, the ISDN Layer Link Status LEDs will be on steady when the Layer 1 link is
established. If there is no link, the LED will be off.
5.
Connect the cable from the NT1 Network Termination cable to the CN2 connector on the BRI PCB.
6.
Tighten the screw on the PCB to secure the card to the cabinet.
