Using the Equipment
with Centrex Services
3
Overview
This chapter explains how your premises equipment works in conjunction with
your Centrex services. The following topics are discussed:
■
Line assignments and ringing
■
Line and extension numbering
■
Popular Centrex services
■
One-touch access to Centrex services.
When you have installed your premises equipment as described in Chapter 2,
the equipment controller sets up your system (using default or “factory” settings)
to work smoothly with your Centrex services. For example, the controller
automatically distributes the Centrex lines connected to your equipment
controller, assigning a primary line to each system extension, and sets all
primary lines for immediate ringing. This means that anyone (inside or outside
the Centrex system) can dial an extension directly, simply by dialing the phone
number. (See “Primary and Secondary Lines” on page 1-5 for more details.)
NOTE:
This guide describes only the operation of your premises equipment; for
information on Centrex services, see the Centrex documentation provided by
your local telephone company.
If you wish to change the defaults described in this chapter, see Chapter 4 (for
information on the options that are available) or Chapter 5 (for equipment
programming procedures).
