Introduction to the DEFINITY system
This section provides you with general information about the DEFINITY ECS
and some of the system-wide functions. It explains how to understand your
configuration, read and use your dial plan, and shows you how to make simple
changes such as adding extension ranges. This section also expl ains how to assign
feature access codes (FAC).

Understanding your configuration

At a very basic level, the DEFINITY ECS consists of hardware to perform call
processing, and the software to make it run. You use the administration interface
to let the system know what hardware you have, where it is lo cat ed, and what you
want the software to do with it.
You can find out which circuit packs are in the system and which ports are
available by entering the command list configuration all. There are variations on
this command that display different types of configuration information. Use the
help function to experiment, and see which command works for you.
