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 2-3 illustrates 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).
