Multiple Phones Dead: No Dial Tone or Lights
Possible Cause 1:
The LED on one system module is out.
What to do:
If the green LED on the front of a module is out, try re-seating the
module in the control unit.
If the LED lights, the problem is corrected.
If the problem remains, call the hotline.
Possible Cause 2:
The green LEDs on several system modules are out.
What to do:
If the LEDs on the front of several system modules are out, try
re-seating the leftmost module of the ones with the lights out (see “Replacing
System Modules” in the
PARTNER Endeavor Installation
guide).
If the LEDs light, the problem is corrected.
If the problem remains, call the hotline.
Poor Transmission Quality on Modem
Possible Cause:
A high-speed modem is connected through an extension jack on
the control unit to a standard Central Office telephone line; but the line quality is
not sufficient to generate a clear signal when the modem transmits through the
system interface.
What to do:
Either connect the modem directly to the network interface jack for a
line, or contact your local telephone company for information about upgrading the
line quality.
If the device works properly, the problem is solved.
If the problem remains, call the hotline.
