Appendix A
Troubleshooting
In the event you encounter a problem using your Telenetics modem, refer
to the troubleshooting information in this appendix.
,
IMPORTANT
If you encounter a problem with your
modem, be sure the switches on the
bottom of the modem are set to the
appropriate positions. If a switch is
halfway between an on and off setting,
the modem will not operate properly.
Problem Solving
Table A-1 offers troubleshooting solutions for modem problems.
Table A-1. Troubleshooting Suggestions
If…
Perform These
Procedures…
Modem does not
respond to the
attached DTE and the
all LEDs are off.
Check the power supply
input for your specific model
(see page 27).
Modem does not
receive data, and the
DCD and RxD LEDs
are off.
The receive line pair may be
disconnected from the
modem. Make sure the
transmission line connection
to the modem is accurate
and secure.
The receive signal level may
be below the CD threshold.
Set SW1-5 ON to see
whether configuring the
modem for a
−43 dBm
threshold resolves the
problem.
