NEC 1093099 User Manual

◆ 123

Prime Line Preference allows an extension user to place or answer a call by just lifting the handset. The user 
does not have to press a line key, loop key, or the 

 key first. This simplifies handling calls. In 

programming, you designate a line key, loop key, the 

 key, a line, or a Line Group as the exten-

sion’s Prime Line. With a line key, loop key, line, or Line Group, the associated line (or lines) becomes your 
Prime Line. With the 

 key, you get Intercom dial tone when you lift the handset. Any number of 

extensions can have the same Prime Line assignment.

There are two types of Prime Line Preference: Idle Prime Line and Intercom Prime Line.

Idle Prime Line lets a user place or answer a Prime Line call by just lifting the handset. An extension’s Idle 
Prime Line can be any line or Line Group, regardless of whether the extension has a line or loop key for the 
line or group.

Idle Prime Line to any line or Line Group is also available at single line telephones.

With Intercom Prime Line, an idle extension user hears Intercom dial tone whenever they lift the handset or 
press 

. Intercom Prime Line may help the extension user that most often uses Intercom functions 

or calls co-workers. If an extension’s Busy Lamp Field is disabled (which is the default), the Feature Keys 
do not go into the DSS mode when the user lifts the handset.

Ringing Line Preference has priority over Prime Line. For example, an extension with Ringing Line Prefer-
ence will answer a ringing line, not get dial tone on their Prime Line. In addition, a Ringing Prime Line will 
have priority over any other ringing line. The seize priority is as follows:

• Ringing Prime Line
• Ringing non-Prime Line
• Prime Line

Lift the handset.

• To bypass your prime line, press another key (such as a line or loop key) before lifting the handset.

Dial call normally.
