Centrex 2000 Service

Centrex 2000 is a complex communications service provided through an arrangement of switching
equipment and facilities which are owned and maintained by the telephone company. Centrex 2000 Service
Lines consist of the facilities from the central office to the customer premises and the central office switching
equipment used to provide intercommunication service.

A Centrex 2000 system involves one or more group(s) of station lines (which can be configured to cover
several locations). The system allows for Direct Inward Dialing, Direct Outward Dialing, 4-5 Digit Station-
To-Station Dialing and many other features and capabilities.

Centrex 2000 Service Lines (which include Attendant Service Lines) can be either Basic (analog) or
ISDN/Electronic (digital). ISDN/Electronic Service Lines offer the ability to connect multiple and/or shared
lines to a single station set. They also offer single-button access to many Centrex features and LCD display
capability (on certain station sets).

INTRODUCTION

This manual provides descriptions of Centrex 2000 features and how to use them. For more detailed
information on how to use your specific station set equipment, consult the documentation provided by the
station set vendor.

Section 1 describes the features available for Analog Service Lines (both Basic and Deluxe).
Section 2 describes the features available for the ISDN/Electronic Service Lines.
Section 3 describes the features available for the Attendant Service Lines (both Analog and ISDN).
Section 4 describes optional system features available for both Basic and ISDN Service Lines.

Features with instruction entries are directly user-accessible. These features can be turned on or off or
modified directly from the users station set.

(Note: Instructions provided in this manual relate to Centrex-programmed switch operations only and do not
necessarily describe the operation of station set equipment. In case of discrepancies between the two, station
set-specific documentation should be followed.)

Features without instruction entries are not directly user-accessible. They determine how the station-set or
