Troubleshooting

TROUBLESHOOTING GUIDELINES

This section provides troubleshooting techniques to alleviate

problems that may be encountered while operating the Express

XRT. If problems persist contact ADTRAN technical support for

assistance (see the back cover of this manual).

Power/Line LED is Off

This indicates a problem with the power to the unit. Verify that

the power cord is connected to the Express XRT and is plugged

into a known working electrical outlet. If the Euro ISDN switch is

selected, this may also indicate that the power is on but the line is

deactivated.

Power/Line LED Flashes and B1 and B2 LEDs are Off

This indicates a problem with the physical connection of the ISDN

line from the local telephone company to the Express XRT.

1. Verify the large end of the RJ-45 to RJ-45 cable (included with

the Express XRT) is connected to the ISDN connector on the

rear panel of the Express XRT.

2. Verify the other end of the RJ-45 to RJ-45 cable is connected to

the ISDN NT1.

3. Contact the local telephone service provider.
