Line Assignment (#301)

Description

This System Programming procedure assigns the outside lines that are available at an extension. The default order of line assignment to the buttons on a system phone is from left to right, starting with the bottom row of line buttons. To put the lines in a different order, first use this procedure to remove all assigned lines; then assign lines in the desired order.

Related Features

■Number of Lines (#104) can be used only during initial system setup to assign a subset of lines to all extensions. You can use Line Assignment to assign additional lines to specific extensions. For example, if five lines were assigned to all extensions and there are eight lines in the system, use this procedure to assign lines 6, 7, and 8 to other specific extensions.

■After you finish Line Assignment, you can use Line Ringing to identify when each outside line assigned to an extension should start ringing.

■You can use Automatic Line Selection to determine the order in which the system selects a line for an extension, when the user at that extension lifts the handset to make a call.

■Remove all outside lines from Hotline (#603) and Doorphone (#604/#605) extensions, to prevent calls from being made or received on them.

■If you want to prevent a user at an extension from accessing a line, make sure you restrict the line using Line Access Restriction (#302) even if the line is not assigned to the extension, so it cannot be accessed using Direct

Line Pickup.

■Users must have access to an outside line in order to dial numbers on the

Emergency Phone Number List (#406).

Considerations

■A line must be assigned to a button with lights. If a line is assigned to a button without lights, you cannot access that line, nor can you program anything else on the button.

■On system phones, assign only as many lines as that extension can use. For example, MLS-12D and MLS-12 phones can have up to 10 outside lines; if you assign 12 lines, the last two lines are assigned to buttons without lights, and are not accessible. In addition, you cannot assign features to those buttons until the line assignments are removed. (The MLS-6 phone can have up to four outside lines.)

■You can assign multiple lines to a standard phone (up to 24 lines), but a single-line phone can handle only one call at a time. To make a call, a user lifts the handset and dials 9 at intercom dial tone; the system selects the first available line based on the Automatic Line Selection programmed for the extension. (Alternatively, the user can use Direct Line Pickup to access a specific line.)
