In system programming (10-51) select either T1 or PRI.
●
If the PCB has already been installed, you may need to remove the PCB, undefine the
slot in Program 90-05, redefine the PCB in Program 10-51, then reinstall the PCB.
Plug the T1/PRI Interface PCB into any universal slot.
●
With normal operation, the status LED will flash fast. If trouble was found during the self
diagnostics routine, the status LED will flash slowly.
●
Once connected, the ISDN Layer Link Status LEDs will be on steady when the Layer link
is established. If there is no link, the LED will be off.
Connect the cable from the NT1 Network Termination cable to the CN2 connector on the T1/
PRI PCB.
●
The CSU connects to the network through an 8-pin RJ45/RJ48 connector. Use either the
RJ48C plug-to-RJ48C plug which ships with the CSU or an RJ45/48C plug-to-RJ45/48C
plug straight through or CAT5 cable to connect the T1 to the CSU. See the table which
follows for the Network and Terminal interface pinouts.
In system programming (10-03) set the PCB for PRI Mode or T1 Mode.
