Lucent Technologies 4.1 User Manual

Possible Cause 1: The switchhook is accidentally pressed and released, causing a call to
ring back.

What to do: Be sure that the handset is always replaced carefully. If the problem is not
solved, go to Possible Cause 2.

Possible Cause 2: Automatic Line Selection is programmed incorrectly.

What to do: If one of the phones involved is a standard single-line rotary or touch-tone

telephone, set its Automatic Line Selection to intercom first. If the problem is not solved,

call the hotline.*

Possible Cause 1: The standard phone is part of a combination extension which includes a
system phone that has Background Music on.

What to do: Check to see if the system phone has Background Music  on. A standard
phone’s message waiting light will not light if Background Music is on at the system phone.

■

If Background Music is on, turn it off. If the standard phone’s message waiting light
lights properly, the problem is solved.

■

If Background Music is not on, go to Possible Cause 2.

Possible Cause 2: The standard phone’s message waiting light is not compatible with the
system.

What to do: See “Standard Telephones” in Chapter 1 for a list of supported standard
phones with message waiting lights. Also check with your Lucent Technologies
Representative or local Authorized Dealer to find out if there are others.

■

If the phone is not supported, you can use it without message waiting capability.

■

If the phone is supported, go to Possible Cause 3.

Possible Cause 3: The standard phone is not connected to the proper hardware.

What to do: Make sure the phone is connected to an R3.1 or later 206 module and the
control unit is equipped with an R3.1 or later processor module. If the problem is not
solved, call the hotline.*
