1.  Press SETUP, the SETUP Menu should be displayed. This

response indicates that there is power to the telephone, and its
microprocessor is operating. Proceed to Step 5. If there is no
display, proceed to Step 2.

2.  Reseat the eight pin connectors of the telephone mounting cord at

the telephone and at either the wall jack or the associated NT1
device.

3.  Verify that the power indicator of the associated NT1 device is

illuminated.

4.  Replace the ISDN telephone with another and repeat the steps in

this section.

5.  Select ADMIN, then MORE, then RESTART, then YES. This will

cause the telephone to reinitialize on Layers 1 through 3. If full
initialization is attained, proceed to “Verify operation” on page 67,
otherwise proceed to Step 6.

6.  Determine which Layer is not initializing by observing the startup

display.

Layer 1 does not initialize:

•

  Locate the NT1 device ahead of the telephone, and press its

reset button. If the NT1 device does not have a reset button,
recycle power by temporarily pulling it out of its rack, or unplug it
from its stand-alone power supply.

•

  Verify all connections between the NT1 and the registered jack

interface.

•

  Replace the NT1 device.

•

  Repeat Step 2.
