Avaya 18d 사용자 가이드

Possible Cause 1: Ringer equivalents are too high for the extension.

What to do: Be sure the total of the two devices’ Ringer Equivalence Numbers (REN) does
not exceed 2.0. If it does, unplug one of the devices.

■

If the phone works properly, the problem is the REN was too high.

■

If the phone still does not work properly, go to Possible Cause 2.

Possible Cause 2: Auxiliary device (such as a fax, answering machine, or modem) is faulty.

What to do: Remove the auxiliary device from the extension and plug in an auxiliary

device that you know works properly.

■

If the phone works properly, the problem is the auxiliary device. Replace the
auxiliary device.

■

If the phone still does not work properly, go to Possible Cause 3.

Possible Cause 3: Phone is plugged into the wrong jack of the bridging adapter.

What to do: Plug the phone into the correct jack—see the PARTNER Plus
Communications System Installalion  guide for instructions. (If an MLS-18D phone is part of
the combination, make sure the second device is plugged directly into the MLS-18D
phone.)

■

If the phone works properly, the problem is solved.

■

If the problem remains, go to Possible Cause 4.

Possible Cause 4: Wrong bridging adapter is used in combination extension.

What to do: First, unplug the bridging adapter from the wall jack. Then, unplug the phone
from the adapter and plug the phone directly into the wall jack.

■

■

If the phone works, there is a problem with the bridging adapter. Replace the
bridging adapter (use only an AT&T 267F2 bridging adapter). If the problem
persists, call the AT&T Helpline.*

If the phone still does not work, call the AT&T Helpline.*
