Troubleshooting the System
QCC Not Ringing for Incoming Calls
l
Possible Cause 5: The telephone may be defective.
What to do: Test the telephone by replacing it with another
MLX-20L telephone that you know is working properly.
• If only one MLX-20L is available, plug that telephone
into a jack that you know is working and then retest. If
the telephone rings for incoming calls, then the original
jack may be faulty; call the Lucent Technologies
Helpline at 1-800-628-2888 (consultation charges may
apply). If the telephone still does not ring, there may be
a problem with the system wiring or the control unit; call
the Lucent Technologies Helpline.
• If the replacement telephone rings for incoming calls,
then replace it with the original telephone and check
again. If the original telephone still does not ring for
incoming calls, then the original telephone may be
defective. Call the Lucent Technologies Helpline at
1-800-628-2888 (consultation charges may apply).
• If the replacement telephone does not ring for incoming
calls, there may be a problem with the system wiring or
the control unit. Call the Lucent Technologies Helpline
at 1-800-628-2888 (consultation charges may apply).
