Multiple Phones Dead: No Dial Tone Or Lights; Poor Transmission Quality On Modem; Other Problems With System - AT&T PARTNER II Release 3.1 Programming And Use Instructions

Possible Cause 2: The power outlet may be faulty.
What to do: Test the outlet by plugging in an appliance, like a lamp or radio.
If the appliance does not work, the outlet is faulty. If possible, plug the control unit
into a different outlet. Then check the fuse box or call an electrician.
If the appliance works, call the AT&T Helpline.*

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 reseating the module in
the control unit.
If the LED lights, the problem is corrected.
If the problem remains, call the AT&T Helpline.*
Possible Cause 2: The LEDs on several system modules are out.
What to do: If the LEDs on the front of several system modules are out, try reseating the
leftmost module of the ones with the lights out (see "Replacing System Modules" in the
PARTNER II Communications System Installation guide).
If the LEDs light, the problem is corrected.
If the problem remains, call the AT&T Helpline.*

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 line quality.
If the device works properly, the problem is solved.
If the problem remains, call the AT&T Helpline.*

Other Problems with System

progress, but does not erase any system settings.
Possible Cause: System needs a hardware reset.
What to do: Unplug the control unit's power cord from the wall. Wait 10 seconds, then
plug it back in. If the problem remains, call the AT&T Helpline.*
