NOMAD MXU TELEPHONE SERVICE PROBLEMS
Problem(s) Possible Cause(s) Solution(s)
.
Bad telephone line. Remove the telephone cable plug from
the back of the MXU and connect it to
a 2 wire analog phone, Note: you may
need a RJ11 adapter. Make a test
phone call between the test telephone
and the 2 wire analog phone. NOTE:
Do not connect a phone directly to
the MXU, it will not work.
Test Step 2: MXU front
panel “Line n LED” does
not light when the MXU
picks up the phone
If the Power On LED is lite, and
the MXU phone pickup is heard,
and the modem tone is heard, but
the Line LED is not lite,
Probably a bad LED
Contact the Gateway to determine the
repair procedure. NOTE: The MXU
probably can still be initialized and
made operational.
Test Step 3: No modem
tone occurs, (may take up
to 1 minute).
If the Power On LED is lite, and
the MXU phone pickup is heard,
and the Line LED is lite,
but no Modem tone.
Probably a bad MXU modem
Contact the Gateway to determine the
repair procedure. NOTE: Without the
NOMAD MXU modem the unit can not
be controlled remotely.
Test Step 4: The Line n
LED does not go out
when the test phone is
hung up.
PSTN non hanging up. Disconnect the telephone line at the
MXU and verify the Line “n” LED goes
out. If so there is a PSTN problem,
