Set the SW1 and SW2 jumpers on the BRI PCB for either T-Bus or S-Bus.
Set the SW1 and SW2 TR jumpers as either terminated or unterminated.
If a BRI daughter board is to be used, set the switches on the daughter board and connect it to
the BRI PCB. (Refer to 2.7.6 BRI (2BRIDB) Daughter Board.)
Plug the BRI PCB into the system KSU.
Before proceeding to Step 7, wait to verify that the STATUS LED starts to flash.
●
With normal operation, the status LED will flash fast. If trouble was found during the self
diagnostics routine, the status LED will flash 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.
Connect the cable from the NT1 Network Termination cable to the CN7 or CN8 connector on
the BRI PCB and/or BRI daughter board.
