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&am[...]

Terminology The following terms are used throughout this guide, and are important for understanding how your system works. In addition, each chapter in this guide begins with a “Terminology” section that defines key terms used in the chapter. All terms are also defined in the Glossary. Centrex Centrex system Equipment controller Equipment featu[...]

How to Use This Guide This guide provides instructions and advice on the following topics: ■ ■ Installation. If you are installing the system for the first time, read Chapters 1 and 2 and Appendix D, which provide an overview of the system, instructions for equipment installation, and equipment specifications. If your company already has modula[...]

Before training co-workers, read Appendix B to decide whether to make intercom calling features available to telephone users. (These equipment features require that users know the jack numbers where lines and extensions are connected to the equipment controller.) In addition, panels 6 and 7 of the Quick Reference card present intercom calling featu[...]

See also Centrex system and Premises equipment. Using Premises Equipment to Complement Centrex Services The system discussed in this guide consists of two elements: Centrex[...]

Any Centrex lines that are not connected to the equipment controller, while they are part of the larger Centrex system, are not considered to be part of the system described in this guide. For example, a hospital might subscribe to a large block of Centrex lines, but connect only the lines for administrative personnel to the equipment controller. I[...]

Primary and Secondary Lines By default, each extension in your system gets one primary line that will be used to receive and place all calls for that extension. When the user at an extension picks up the handset to make an outgoing call, the primary line for the extension is automatically selected. Likewise, all incoming calls on the primary line r[...]

Features and Capabilities Your equipment controller supports the following features to complement your Centrex services: ■ ■ ■ Multiple line assignments, permitting more flexible call coverage. For example, the equipment controller automatically assigns all lines to the first phone connected to the equipment controller, to serve as a possible[...]

Centrex Line Assignments and Ringing Your local telephone company provides a block of Centrex lines that are used with your telephones. When you connect these lines to your equipment controller and supply electrical power, the controller automatically assigns one Centrex line to each extension. The only exception is the phone connected to extension[...]

Each telephone is connected (either directly or through a wall jack) to an ■ extension jack on the equipment controller. Each extension jack on the controller is identified by an extension jack number. Extension jack numbers run from 10 through 33 (if you have the maximum number of extensions that can be used with your premises equipment). Line j[...]

Centrex Services With each Centrex line, you have a set of Centrex services (some services may not be available on all lines). Table 3-1 lists some of the most popular Centrex services.

Some features require buttons with lights. Other features do not require buttons with lights, but do use the lights to show status information if they are available. For features that can be turned off and on by the user (such as Do Not Disturb and Privacy), the features are on whenever the lights are on. NOTE: The lights on MLS-model phones do not[...]

Example: A person at a covering extension who screens another extension’s calls may need an Intercom Calling button for the covered extension (possibly with voice paging) to announce calls and visitors. The lights beside the Intercom Calling button show when the covered extension is busy. To program an Intercom Calling button, see page 5-15. Pagi[...]

Intercom calls can be made w[...]

■ ■ ■ ■ The equipment controller can store a maximum of 80 System Speed Dial numbers (dial codes 20-79).

NOTE: While procedures that restrict dialing are very effective, absolute protection against misuse cannot be guaranteed. MLS- and MLC-model phones give more protection than standard phones. Therefore, we strongly recommend that you install MLS- and MLC-model phones where restricting phone use is important. When an extension is allowed access to a [...]
