Troubleshooting the DSX-1 Interface

To troubleshoot a DSX-1 interface, you must first isolate the problem. Is the
problem with the PBX? With the DSX-1 interface? With the T1 interface? Or is
the problem with the public carrier's equipment?
Alarms or Errors That Will Not Clear
When you are unable to clear alarms or errors in the Secure Router OS, the
device at the other end of the cable is often at fault. To isolate the problem,
disconnect the cable from the PBX and loop the DSX-1 interface back on itself
using an external cable. If the unit goes out of alarm, you know that the PBX
is at fault.
