Tips for a great answer:
The green lights next to the line or pool buttons show the current Line Ringing settings for all
lines or pools assigned to the extension. (If a line or pool is not assigned to a button, the green
light next to that button is off.) The following ringing options can be shown by the green light
next to the line or pool button:
? Immediate Ring - on steady
? Delayed Ring - flashes slowly
? No Ring - flutters quickly
3) Press the line or pool button until the button light shows the correct setting (the setting for the
currently selected line or pool also appears on the display).
4) Continue programming, or exit programming mode.
For incoming calls, the line selection (hunt sequence) is set by the local service provider). For outgoing calls....again....it depends on the system. For the Partner ACS:
1) Press FEAURE 00, SYSTEM PROG, SYSTEM PROG, CENTRAL PROG at extension 10 or 11.
2) Enter the number of the extension to be programmed for Automatic Line Selection.
3) Press **.
4) Press the line, pool, or INTERCOM buttons in the desired order. The valid entries for Automatic
Line Selection depend upon the type of extension:
? Key Extension: Outside system lines, Left Intercom (the factory setting)
? Pooled Extension: Pool 880 button 1, button 2, Left Intercom, Right Intercom (the factory
setting), Pools 881-883, individual lines
For each button pressed, a display similar to the following appears:
Automatic Line Selection
5) To exit Automatic Line Selection, press **.
6) Press CENTRAL PROG and enter a new extension number, or exit programming mode.
Changing line ringing and line selection are tasks that are normally reserved for the Administrator of the telephone system.

Here's how to program line ringing:
• go to the voice terminal whose line ringing you want to program
• slide T/P switch toward you
• touch a line button (note red lights)
• touch the button again until correct code appears:
RED ON = Ring
RED FLASH = Delayed Ring
RED OFF = No Ring
• repeat this procedure for each line
• return T/P switch to center position.
