Using System Programming

System Programming changes settings for the system as a whole, or for individual lines or extensions. You can use System Programming to set up dialing restrictions, define groups, or set up auxiliary equipment. Refer to the filled-out System Planner when you are changing system settings, and be sure that any changes in programming are recorded there.

The Programming Overlays

System Programming requires a programming overlay placed over the dial pad of the MLS-34D, MLS-18D, or MLS-12D system phone at extension 10 or 11. (Overlays are provided with the system documentation. Replacements can be ordered through the AT&T Sourcebook.) Figure 2-3illustrates the programming overlays.

During System Programming, the normal functions of several buttons on the display phone at extension 10 or 11 change. For example, the left [ Intercom ] button becomes [ System Program ], the button used to enter programming mode. The programming overlay identifies these buttons.

You use the following special button while programming:

[ Next Procedure ] and [ Prev Procedure ] cycle forward and backward through the programming procedures. You can use these buttons to select a procedure.

[ Next Item ] and [ Prev Item ] cycle forward and backward through a procedure’s parameters. A parameter is typically an outside line, an extension, or a telephone list entry.

[ Next Data ] and [ Prev Data ] cycle forward and backward through the valid entries. These buttons work only for fixed data, such as a line or extension number. They do not work for variable data such as date, time, password, telephone numbers, or doorphone assignments.

[ Remove ] returns the current setting to the factory setting—or when using Line Assignment (#301), removes lines from an extension.

[ Enter ] ends an entry of variable length, such as a telephone number in an Allowed Phone Number List.

[ System Program ] starts the System Programming process.

[ Central Tel Program ] starts the Centralized Telephone Programming process (to customize individual telephones centrally from extension 10 or 11).

[ Feature ] when followed by [ 0 ] [ 0 ], enters or exits programming mode.

[ Wild ] enters a “wildcard” (a character that matches any digit dialed) in telephone numbers in Allowed Phone Number Lists (#407), Disallowed Phone Number Lists (#404), and the Forced Account Code List (#409).
