Programming Overview

Introduction to System Programming

The Communications System offers easy-to-use, menu-driven software for
system programming. After your system is installed, you use this software to
reconfigure, update, or modify your system according your changing business
needs, such as modifying or upgrading lines, telephones, and modules
connected to your system.
Planning Forms
Before you begin to program or modify your communications system, you
should familiarize yourself with the system planning forms. Initially, system
planning forms are used to plan your communications system and program your
system during installation. After installation, they remain a source for all
programming information on your communications system database. The
information ranges from the system time and date to specific equipment
configurations and feature programming.
Each planning form is either required or optional:
required — forms needed to program the system.
optional — forms needed only if the system included the features or
options on the forms.
Before you begin to program or modify your system, review the control unit
diagram on System Planning Form 1 to identify the module types installed in the
system's control unit. Use this information to program or modify lines and trunks
and assign or reassign lines to telephones. Check the physical control unit to
verify that the modules are placed in the slots identified on the diagram and
correct the diagram on System Form 1 if there are any discrepancies" .
Before you make any changes to your system, be sure to do the following:
Keep your planning forms up-to-date by indicating any system
modifications or changes on the appropriate form after the change is
made.
Check the Feature Reference for possible feature interactions.
Program the system or the system component during the appropriate
idle state. See "Idle States" later in the chapter.
