AT&T AT&T manual Prime Line Preference, Ringing Line Preference, 155

LINE SELECTION

Description

Multiline voice terminals may have many line (facility) appearances. There are three methods by which a user may select a desired line: (1) Prime Line Preference, (2) Ringing Line Preference, and (3) Preelection.

Prime Line Preference:

Automatically connects a multiline voice terminal to a specified line or facility designated as preferred when the terminal goes off-hook. This feature may be assigned to System Access, Loop, Automatic Intercom, DSS, Personal Line, and Direct Facility Access buttons.

On the Switched Loop Attendant Console (V2), the topmost Loop button has Prime Line Preference by default. However, the feature can be assigned to any of the five Loop buttons.

The user may override this feature by preselecting another button (see below).

If Prime Line Preference is assigned to an Automatic Intercom (AUTO ICOM) or DSS button, the called voice terminal will ring as soon as the terminal goes off hook.

When the Prime Line Preference feature is assigned to an AUTO ICOM, DSS, or Direct Facility Access (FACILITY) button, the button must be pressed to activate the busy-to-idle reminder even though the button’s I-Use LED is lighted steadily.

If Prime Line Preference is assigned to a Personal Line button, the user is connected to the button upon going off-hook, even if the line is busy. For V1 systems only: if Prime Line

Preference is assigned	to	a	button that	has a call on hold, no connection	will be made; to get
a line for placing a call,			the user must press another button. In V2		systems, the user is
always connected to	the	button where		Prime Line Preference is assigned,	even if the line has
a call on hold; if the user wishes to				use a different line, the line may	be preselected before
going off-hook.

Ringing Line Preference:

Automatically connects a multiline voice terminal to an incoming call ringing at the terminal.

Line access buttons that can be selected by Ringing Line Preference include System Access, Automatic Intercom, Coverage, and Personal Lines.

If two or more lines on a multiline terminal or a Direct Trunk Attendant Console are ringing simultaneously, the user is connected to the first line to start ringing. If the user wishes to use a different line, the line must be preselected prior to going off-hook. If ringing ceases while the user is on-hook, line preference reverts to whichever option is applicable (Prime Line Preference or no preference).

If a line rings at a multiline terminal when the terminal is busy on another call, Ringing Line Preference will not activate, even if the user goes on-hook during the ringing cycle. However, Ringing Line Preference is not canceled at the Attendant Console while the attendant is off-hook. If a line is ringing while the attendant is off-hook, the ringing line will be selected as soon as the attendant goes on-hook.
