How to Troubleshoot Connection Problems continued
Symptom: Remote Module cannot connect to Switch Card
Action: In the event that the remote module cannot establish a connection to the Switch Card, it is very important to note the error message on the remote phone display.
Error Message
on Remote
Phone
Connect Error No Carrier
Possible Cause
The modems cannot negotiate a connection. Either there is noise on the analog line, or the remote unit is calling the wrong phone number.
Action
Ensure that the proper PBX Phone Number is entered into the Dial numbers menu on the remote module. Ensure that it is placing a call to Switch Card by listening for the ring and modem answer on the remote module speaker.
Restart the Switch Card. It will blink yellow, green, yellow, yellow once it has restarted. Attempt to connect the remote module. If it fails, observe the LED sequence on the Switch Card. Yellow, green, yellow, yellow means that it has not received a call and the remote module PBX Phone Number is wrong. Yellow, green, green, yellow means that the Switch Card received a call, but the modems could not negotiate a connection. Lower the connect rate on the remote module. Yellow, green, green, green means that the modems did negotiate properly and the failure is not related to “No Carrier.”
