Connection Errors
There is a problem with the physical connection with the ISDN line interface.
Ensure your Extender is fully connected with the ISDN line, check cables and
jack connections.
Check ISDN parameters. The Remote Module ISDN is not responding. The
Remote Module is not connecting to the ISDN Network. Ensure the ISDN
parameters and Dial numbers are correct and the Remote Module connects to
the line.
At times when the Extender places a call, if the previous call failed to connect,
the network requires a delay between the next call attempt. If you do not wait
long enough, this message is displayed. If connection fails, re-attempt to Go

Possible ISDN Connect rate problem. Your Office Module digital port may be
offline or disconnected. Or you are connected to an incompatible communica-

tion. Try changing your ISDN Connect Rate from Auto to 56k. Ensure Office
