AT&T Partner II - Manual (Page 6)

About This Guide
Purpose
The system described in this guide consists of premises equipment and Centrex
services. Although the terms “premises equipment,” “Centrex services,” and
“system” have broader meanings elsewhere, this guide uses those terms to
refer specifically to the following definitions:
Premises equipment refers to the AT&T equipment controller and MLS- ■
and MLC-model telephones that you purchased as part of your Partner®
II Centrex Communications System, plus all other telecommunications
devices connected to your equipment controller. This equipment is
installed at your place of business.
■ Centrex services include the Centrex lines that are connected to the
equipment controller and the features available on those Centrex lines.
These services (which may be offered in your area under a different name
such as ESSX,® CENTRON,® or Plexar®) must be arranged for
separately with your local telephone company.
■ System refers to the combination of premises equipment and Centrex
services described above.
The main purpose of this guide is to provide instructions for installing,
programming, and using your premises equipment. Because the selection of
services available from the local phone companies continually expands and
changes—to keep pace with the needs of businesses and with technological
advances in the world of communications—this guide does not provide detailed
information about Centrex services. For specific information about your Centrex
services, see the Centrex documentation provided by your local telephone
company.
