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.

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 modular jacks for all outside lines and extensions, you may be able to use the existing wiring to install the equipment controller and connect telephones yourself (see Chapter 2). If you prefer to have an AT&T service technician install and customize your premises equipment, call 1 800 247-7000 (in the U.S. only) or your AT&T authorized dealer.

Your system can include a wide variety of auxiliary equipment, including fax machines, modems, answering machines, credit card scanners, and call reporting (SMDR) devices. See Chapter 7 for advice on setting up these industry-standard devices to work effectively with your system.

Setup Decisions.

If you are a new user, read Chapters 1, 3, 4, and 6, to familiarize yourself with the features provided by your equipment controller, to learn how to program the equipment controller and individual phones, and to learn how to handle calls.

Chapter 3 explains how your equipment controller complements Centrex services, providing a variety of features that support Centrex capabilities and making it easy for you to access Centrex features. Chapter 4 helps you make decisions about customizing the premises equipment, to use additional features and capabilities provided by your equipment. Chapter 6 provides call-handling instructions for standard phones and for MLS- or MLC-model phones.

Programming.

Chapter 5 gives step-by-step instructions for all of the programming procedures for your premises equipment. You can use the information in this chapter as a reference, to help you carry out your decisions about customizing your premises equipment.

Making Changes.

If you need to reprogram the premises equipment or individual extensions, see Chapter 5, “Programming Reference,” or the Programming Quick Reference pages at the back of this book.

If you are adding equipment to your system, see Chapter 2, “Installing the Equipment,” Chapter 5, “Programming Reference,” and Chapter 7, “Using Auxiliary Equipment.”

Training Co-Workers.

Chapter 6 explains how to handle calls and use equipment features effectively. To help users get the most out of their phones, give each telephone user a Quick Reference card and filled-in copies of the “Speed Dial Numbers” form in the System Planner or Appendix A of this book.

■

About This Guide

vii

Page 9

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 features.

Solving Problems.

Appendix C provides information on solving problems and ordering additional accessories and equipment. If your premises equipment malfunctions, you may be able to solve the problem by following the steps provided in “Troubleshooting,” starting on page C-3.

Daily Operation.

Depending on how your system is set up, you may

■

need to oversee some of the system’s daily operations. For example, if

you use the Night Service feature available with your equipment controller, you will need to turn on Night Service at the end of each day before leaving the office. (See “Using Night Service” on page 6-18.)

Once you are experienced with the system, use the Table of Contents or Index to locate the information you need.

Product Safety Labels

This book contains several product safety statements, identified by a

CAUTION:

Indicates the presence of a hazard that will or can cause minor personal

injury or property damage if the hazard is not avoided.

WARNING:

Your premises equipment, in combination with the Centrex lines that are connected to your equipment controller and the Centrex services that are available on those lines. 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 services (including Centrex lines and associated features) and premises equipment (including the equipment controller, MLS- and MLC-model telephones, and other telecommunications devices connected to the controller).

The Centrex services you receive from your local telephone company provide a unified telephone network for your business, even across different geographical locations, and give you services customized for your needs.

NOTE:

Your telephone company may offer Centrex services under a different name (for example, ESSX,® CENTRON,® or Plexar®). Also, you may be able to select different services for different lines. (For more information, see the Centrex documentation provided by your local telephone company.)

Your AT&T premises equipment is designed to complement the advantages offered by Centrex. All or some of your Centrex lines may be connected to the equipment controller. You can connect a maximum of 24 Centrex lines and 24 extensions to your equipment controller. Figure 1-1 shows an example in which some Centrex lines are connected to the equipment controller and some are not

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. In this situation, the telephones for administrative personnel would be managed by the equipment controller as a distinct system within the larger Centrex system.

One of the most important Centrex features is the assignment of one Centrex line for each extension in your system. This allows a caller to reach an extension directly, simply by dialing the extension’s phone number, as shown in Figure 1-2. The call rings at the extension immediately, so you do not need to have a receptionist who answers calls for all system extensions and then transfers each call to the appropriate user.

Figure 1-2. Dialing a System Extension

The equipment controller complements Centrex by automatically assigning a primary line to each extension (see “Primary and Secondary Lines” on the next page), and by passing Centrex ringing patterns through to phones. (The major benefits provided by your equipment controller and the AT&T phones that you

connect to it are discussed in “Features and Capabilities” on page 1-6; in addition, Chapter 3 provides a more detailed discussion of the way your premises equipment and Centrex services work together.)

The equipment controller also provides optional features, some of which may be similar to Centrex services you have. (Optional equipment features are listed at the end of Chapter 4 in this guide.) If you have similar features available from Centrex and from the equipment controller, you should use the Centrex features.

NOTE:

The System Planner, available separately, provides forms you can use to plan your system configuration and to identify your Centrex services. If you do not already have a copy of the System Planner, see “Reference Materials” in “About This Guide.”

1-4 Overview

Page 16

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 ring immediately at the user’s phone. The primary line always appears on the bottom leftmost line button on an MLS- or MLC-model phone. Except for Hotline phones and doorphones (see page 4-23), each extension in your system has a primary Centrex line.

You can also assign secondary lines to extensions. Secondary lines are lines other than the primary line, typically assigned to a phone for call coverage purposes. Secondary lines generally use delayed ringing; when a call comes in on a line, it rings first at the extension where the line is assigned as a primary line; only after about 20 seconds does it begin ringing at an extension where it is assigned as a secondary line. Likewise, when a user picks up the handset to make an outgoing call, the extension’s primary line is selected automatically. A secondary line is selected automatically only to answer an incoming call (if the call is already ringing at your phone when you pick up the handset).

All lines are automatically assigned to the first phone connected to the equipment controller; but only the line assigned to the bottom leftmost line button on the phone is primary. All of the other lines assigned to the extension are secondary lines. (This default line arrangement provides Central Call Coverage; for more information about this and other call coverage options, see page 4-3.)

NOTE:

Secondary lines assigned to an extension are used as primary lines at other extensions. To avoid tying up another user’s primary line, callers who have secondary lines should always use their own primary lines to make outgoing calls.

Overview

1-5

Page 17

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 receptionist’s position. In addition, you have the option of assigning secondary lines at other phones, to provide Local Call Coverage, so that a person can answer calls on a line when the line’s primary user is absent or busy. The equipment controller also passes Centrex ringing patterns through to each phone (for example, to distinguish between outside and inside calls). When a line is assigned to an MLS- or MLC-model phone, the lights on the line button let you see the activity on the line.

Programmable buttons on MLS- and MLC-model phones, providing one-touch access to both Centrex and equipment features). You can access a feature simply by pressing the button.

Easy-to-use programming procedures, making it easy for you to manage your system. You can change line assignments, call coverage arrangements, or programmable buttons, quickly and easily. (The display on an MLS-34D or MLS-12D phone provides feedback during programming.)

Modular connections to the equipment controller, making it easy for you to reconfigure your system or to add extensions as your system grows.

Direct connections for industry-standard devices—including standard phones, fax machines, answering machines, modems, and credit card scanners.

Optional equipment features, including paging over a loudspeaker paging system or over MLS-model phone speakers, music on hold*, call detail recording (also known as Station Message Detail Recording, or SMDR), night service operation, speed dialing, line access restrictions, and many others.

Power failure operation with standard phones, allowing you to make and

■

answer calls during a power failure while retaining programmed equipment settings for up to four days. (An optional Uninterruptible Power Supply, or UPS, is also available to allow full equipment operation during a power failure.)

If you use equipment that rebroadcasts music or other copyrighted materials, you may be required to obtain a license from a third party such as ASCAP or BMI. Or, you can purchase a Magic on Hold® device from AT&T that does not require you to obtain such a license.

Equipment Controller

The equipment controller is the heart of your premises equipment. It is made up of one or two carriers — the plastic housing consisting of the backplane and cover. The backplane distributes power to the premises equipment, and has

slots where modules are placed; the cover slides onto the front of the backplane

after all the modules have been installed. The system must have a primary carrier for support of up to 12 lines and

extensions, and can be expanded to include an expansion carrier for support of up to 12 more lines and extensions. A fully loaded system has both carriers.

Modules

The following modules are installed in your equipment controller:

■

Primary processor module.

The primary processor module manages the components of your premises equipment. It has jacks for a music-on-hold audio source, a loudspeaker paging system, and a call reporting device (SMDR), such as a printer. The primary processor module is always installed in the center slot of the primary carrier.

Expansion processor module.

(optional) The expansion processor module extends the primary processor module’s management capabilities to the lines and extensions connected to modules in the expansion carrier. An expansion cable connects the primary processor module to the expansion processor module. This module is always

installed in the center slot of the expansion carrier.

206 Modules.

Each 206 module connects a maximum of two Centrex

lines and six extensions to the equipment controller. You can connect telephones and other telecommunications devices (such as fax machines, answering machines, or modems) to the extension jacks on the 206 module (either directly or through your building’s extension jacks). Each 206 module has a green power indicator that shows it is

receiving power from the equipment controller. At least one 206 module

is required in the leftmost slot of the primary carrier.

400 Module.

The 400 module is similar to the 206 module, but without

■

extension jacks. It has jacks for four Centrex lines. The 400 module is always installed to the right of a 206 module.

Capacity

The number of 206 and 400 modules you install in the equipment controller

determines the number of available lines and extensions. The controller

implements the Centrex requirement of one line for each extension. Therefore, when you install a 400 module (four lines) next to a 206 module (two lines, six extensions) in a carrier, the combined pair provides an equal number (six) of

lines and extensions. For the maximum number of lines and extensions in a two-carrier configuration, pair four 206 modules with four 400 modules—for a total of 24 lines and 24 extensions.

MLS- and MLC-Model Telephones

AT&T MLS- and MLC-model telephones are designed to make maximum use of the features provided by your system. The following models are available for use with your system:

■

AT&T MLS-34D Telephone.

This phone is the best choice for extensions used by the system manager (for equipment programming), receptionist, or operator. It has 32 buttons that can be used for outside lines or programmed for one-touch access to features. It also has a built-in speaker and microphone (for dialing and having a conversation without lifting the handset) and a large character display that shows the following:

■

Current date, day, and time

■

Number you dialed and elapsed time (when you make a call)

■

Prompts and messages.

AT&T MLS-12D Telephone.

This phone has 10 buttons that can be used for outside lines or programmed for one-touch access to features (and 6 more buttons without lights that can only be used for programmable features). It has a built-in speaker and microphone, and a display similar to the one on the MLS-34D telephone.

NOTE:

An MLS-34D or MLS-12D telephone is required for equipment programming. Use the MLS-12D phone only if there are no MLS-34D phones installed at the site.

AT&T MLS-12 Telephone.

This telephone has all the features of the

MLS-12D telephone, but without a display.

AT&T MLS-6 Telephone.

This phone has 4 buttons that can be used for outside lines or programmed for one-touch access to features. It also has a built-in speaker, but no microphone. This means that a user can dial a number without lifting the handset, but must lift the handset to speak when the party answers.

AT&T MLC-6 Cordless Telephone.

This cordless telephone works like

■

the MLS-6 corded telephone. It has 4 buttons that can be used for outside lines or programmed for one-touch access to features. It also includes a display that shows line status, an On/Off button that must be pressed before using the phone (to save battery power), and additional feature buttons to support cordless operation (for more information, see

MLC-6 Cordless Telephone Quick Reference: Display and Controls).

Auxiliary Equipment

The premises equipment works with many telecommunications devices, not only MLS- and MLC-model telephones. You can connect industry-standard devices to your equipment controller, and certain models of other devices, all without expensive adapters.

Overview

1-9

Page 21

Industry-Standard Devices

Many industry-standard, single-line telecommunications devices will work with

the equipment controller:

Standard touch-tone, rotary, and cordless telephones (such as those you

■

might have in your home), including feature phones with built-in feature buttons and lights

■

Fax machines

Answering machines

■

Modems

■

Credit card scanners.

Limitations

You can connect standard devices to your equipment controller, regardless of

the manufacturer. The following limitations apply:

The device must be industry-standard and non-proprietary. That is, it

■

cannot be made specifically for use on a particular telephone system. (For example, you cannot connect an AT&T MERLIN® phone, because it is specifically designed for use on a MERLIN system.)

NOTE:

You

can connect a multiple-line device to the equipment controller, but for best

results it should be installed and used as if it were a single-line device.

The device’s Ringer Equivalence Number (REN*) cannot be greater than

■

2.0. (The REN is shown on a label on the device, usually on the bottom.)

Connecting and Using Standard Devices

You can connect a standard device so that it is on an extension by itself, or so that it shares an extension with another piece of equipment (either another standard device or an MLS- or MLC-model phone). An extension with two devices connected to it is called a combination extension. For example, you can connect an MLS-model phone and a standard phone to the same extension, so that the standard phone can be used to place and receive calls in

the event of a power failure. To connect two devices on one extension, you

need an inexpensive AT&T 267F2 bridging adapter (two are provided with each

206 module). Chapter 2 explains how to connect standard devices to the equipment controller

and how to combine them on a single extension. (See page 2-5 for installation

instructions for combination extensions.) For additional information on programming and using fax machines, answering machines, modems, or credit card scanners, see Chapter 7.

REN is a measure of the power it takes to ring a phone. A typical home phone line handles 4.0–5.0 RENs; each extension jack in your equipment controller can handle 2.0 RENs.

1-10

Overview

Page 22

Other Devices

You can connect other devices to your equipment controller, but only specific models are compatible with the equipment controller. (See Appendix C for

product ordering information.)

■

Call accounting devices and printers

allow the system manager to print call reports. The call accounting device or printer connects directly to the primary processor module in the primary carrier. See “Call Reporting Devices (SMDR)” on page 7-7 for more information.

Doorphones

allow visitors to alert up to five extensions at once by pressing a button on the doorphone; the person who answers a doorphone call can then use the phone to speak to the visitor at the doorphone. The equipment controller supports up to two proprietary doorphones, which can be installed indoors or outdoors. A doorphone is especially useful for providing access to offices or departments after hours. For example, you can install a doorphone outside your building entrance to allow visitors to alert telephones inside the building when the receptionist is not there and the front door is locked.

Loudspeaker paging systems

allow you to broadcast a message over a large area, by connecting the paging system directly to the PAGE jack on the primary processor module. The equipment controller supports all AT&T paging systems. For information on how to use a loudspeaker paging system with the equipment controller, see page 6-17.

Music-on-hold systems

allow you to play recorded music to callers while they are on hold, by connecting the music-on-hold system to the primary processor module. The equipment controller supports the AT&T Magic on Hold system and most models from other manufacturers.

Extra alerts

are strobes, lights, chimes, horns, or bells that light or ring when calls come in. For example, you can use an audible alert (chime, horn, or bell) to replace a phone ring in a noisy area, such as a factory. Similarly, you can use a visual alert (strobe or light) to replace a phone ring in a quiet area, such as a library.

Electromagnetic Interference (EMI) filters

allow you to block “noise” generated by a nearby radio station, as well as most electrical devices. The equipment controller supports the AT&T Z300A EMI Filter.

Uninterruptible Power Supply (UPS)

allows full equipment operation during a power failure. The equipment controller supports the AT&T 360VA UPS.

In-Range Out-of-Building (IROB) protectors

are required to prevent electrical surges from damaging your equipment when phones are installed in another building, but on the same continuous property. The equipment controller supports the AT&T IROB protector, which provides coverage over a distance of 3,000 feet for standard phones and 1,000

feet for MLS- and MLC-model phones. (For installation instructions, refer to the booklet packaged with the IROB protector.)

■

Overview

1-11

Page 23

Speakerphones

provide hands-free two-way operation of a phone without lifting the handset. Combining a speakerphone with an MLS-model phone or a standard phone on an extension in a conference room or office is an inexpensive way for several people at a meeting to conference with other parties. The equipment controller supports the AT&T S203 speakerphone. (MLS-model phones have built-in speakers, but they are designed for individual—not group—use.)

Repertory dialers

allow you to store frequently-used numbers for one-touch dialing (Auto Dialing). If a user needs many Auto Dial numbers, a repertory dialer can be combined on an extension with an MLS- or MLC-model phone or standard phone.

Headsets

allow users to hold private, hands-free conversations. A headset is a combination earphone and microphone worn on the head, useful for receptionists, salespeople, or others who need to have their hands free while talking on the phone. AT&T offers several compatible headsets.

Handsets for the hard-of-hearing

are designed for users who need even more amplification than is provided by the volume controls on MLSand MLC-model phones. Although the volume controls on MLS- and MLC-model phones significantly reduce the need for an amplified handset, hard-of-hearing users may find that the AT&T K6S handset meets their needs.

Installing the Equipment

This chapter explains how to install the premises equipment. It begins with general guidelines to consider before installation, followed by an example configuration. It ends with step-by-step instructions for connecting and testing the components.

IMPORTANT:

Before installation you should review Forms A and B of the System Planner to identify the type of equipment that should be connected to the extension jacks

for your system.

Terminology

The following terms are used in this chapter. In addition, you may wish to review the “Terminology” section of “About This Guide, ” which defines basic terms

used throughout this guide, or the Glossary, which defines all terms.

Backplane

The bottom and rear portion of the plastic housing that makes up a carrier. The backplane distributes power to the premises equipment, and has slots where the modules are installed.

Carrier

Molded plastic housing, made up of a backplane and cover, which holds the equipment controller modules. Your configuration contains at least the primary carrier and can be expanded to include an expansion carrier.

Combination

An extension that has two devices connected to it using a

extension

The location on 206 and 400 modules that allows you to

connect Centrex lines to the equipment controller. The number assigned to each line jack on a 206 or 400

module. Line jack numbers run consecutively from 01 through 24 (for a two-carrier configuration).

A jack, generally located in your equipment room, that provides access to a Centrex line coming into your building

from your local telephone company. A telephone cord from the network interface jack to a line jack on a 206 or 400

module connects the Centrex line to your system. The AT&T equipment controller and MLS- and MLC-model

telephones that you purchased as part of your system, plus

all other telecommunications devices that are connected to your equipment controller. For purposes of this guide,

premises equipment does not include any equipment that connects directly to Centrex lines without going through the equipment controller.

The required component of the AT&T equipment controller that contains the primary processor module and up to two 206 and two 400 modules. This provides for connection of up to 12 lines and 12 extensions. See also Expansion carrier.

206 Module

The AT&T equipment component that contains jacks for connecting up to two Centrex lines and up to six extensions to the equipment controller.

Installation Guidelines

In this chapter, we refer to line jacks and extension jacks; these terms describe the locations where connections are made to the equipment controller. During installation, each Centrex line is connected to a line jack on the controller. In addition, each phone (or optional device) is connected to an extension jack on the controller (either directly or via a wall jack). Once connections are made, the controller associates each line jack (numbered consecutively from 01 through 24) with a specific extension jack (numbered consecutively from 10 through 33). Each Centrex line is the primary line for the phone at the corresponding extension. (Refer to Form B in the System Planner, which records how your phone numbers are assigned to system extensions.)

Placement of Carriers and Modules

Carriers.

You will be installing either one or two carriers, depending on

■

the number of lines you have (see “Capacity,” on page 1-8). If you are going to install the expansion carrier, plan to install it to the right of the primary carrier. Install the backplane(s) within five feet of the network

interface jacks and a grounded 110 VAC electrical outlet not controlled by a switch. If you are installing two carriers, both must be plugged into the same power outlet. In addition, when you mount the backplane(s) on the

wall, leave at least six inches of clearance at the top and sides, and two feet at the front and bottom.

Modules.

To install modules, follow the rules below:

■

Install the primary processor module in the center slot of the primary

■

carrier.

■

If you are installing the expansion carrier, install the expansion processor module in its center slot.

■

The first (leftmost) slot in each carrier must contain a 206 module.

■

Do not skip slots when installing 206 and 400 modules. A 400 module must be installed to the right of each 206 module

■

(except the last 400 module, which can be skipped if you do not need the additional lines).

If a second 206 module is installed in a carrier, it must be installed to

■

the right of the processor module.

Figure 2-1 shows the two carriers, with line and extension jacks numbered, for a configuration containing 24 lines and 24 extensions. For a detailed explanation of line and extension jack numbering, see Chapter 3.

Connection of Telephones and Devices

You can connect the following telephones and devices to the equipment

controller:

■

MLS- and MLC-Model Phones.

MLS- and MLC-model phones require at least two-pair wiring and are compatible with AT&T four-pair SYSTIMAX™ wiring. If you need a shorter cord for wall mounting, use AT&T’s two-foot D4BU-29 mounting cord (available separately—see page C-12). An MLS-34D phone connected to extension jack 10 or 11 is used for System Programming. Use an MLS-12D phone for System Programming only if there are no MLS-34D phones installed at your business site.

Industry-Standard Devices.

Industry-standard equipment (including standard phones) require one-pair mounting cords; AT&T D2R mounting cords are recommended.

■

Standard Phones.

Connect standard touch-tone or rotary phones to the equipment controller for: —

Power Failure Operation.

During a power failure, MLS and MLC-model phones will not work because they require power to operate. However, if standard phones are connected to extension

jacks 10, 16, 22, or 28, they can place and answer calls on lines at

line jacks 01, 07, 13, or 19, respectively. Connect a standard phone to one or more of these extensions, either alone or

combined with an MLS- or MLC-model phone. (If you combine a standard phone and an MLS- or MLC-model phone on one extension, you may want to turn off the standard phone’s ringer during normal use.)

2-4

Installing the Equipment

Page 30

Hotline Phones.

A Hotline phone should be a standard phone—not an MLS or MLC-model phone—but can ring any type of phone. You can specify one alert extension for each Hotline phone, and you can install multiple Hotline phones, if you wish. A Hotline phone only requires connection to an available extension

jack (with no Centrex line assigned to the extension). To simplify

programming, we recommend installing Hotline phones and doorphones on the last available extension jacks on the last installed 206 module in the equipment controller (if the last module in the equipment controller is a 206 module with no corresponding 400 module, the last four extension jacks will not have Centrex lines assigned to them by default).

Auxiliary Equipment.

There area variety of ways to set up fax

■

machines, modems, and answering machines to work with the equipment controller. See Chapter 7 for advice on using this equipment. To connect a telephone and a fax on the same extension, see “Combination Extensions” below.

Doorphones.

You can connect up to two proprietary doorphones to the equipment controller. Like Hotline phones, doorphones only require connection to an available extension jack (with no Centrex line assigned

to the extension). To simplify programming, we recommend installing doorphones and Hotline phones on the last available extension jacks on the last installed 206 module in the equipment controller (if the last module in the equipment controller is a 206 module with no corresponding 400 module, the last four extension jacks will not have Centrex lines assigned to them by default).

Call Reporting Devices.

You can connect a call accounting device to the SMDR jack on the primary processor module for recording call activity. (See “Call Reporting Devices (SMDR)” on page 7-7 for more

information.)

In-Range Out-of-Building Protectors.

Installing phones in a different

■

building from the equipment controller requires AT&T In-Range Out-of-Building (IROB) protectors, to prevent damage due to lightning (installation instructions are included with the protector).

Combination Extensions

You can connect a standard device (such as a standard phone or a fax machine) on an extension by itself, or you can use an AT&T 267F2 bridging adapter (only) to combine the standard device with another standard device or an MLS- or MLC-model phone at one extension jack. You cannot install two MLS- or MLC-model phones on the same extension, and the combined REN of two devices on an extension must be no more than 2.0. Figure 2-2 shows how

to connect the two devices to the bridging adapter at a combination extension,

Example Configuration

These two pages show an equipment controller with three 206 modules and three 400 modules, giving this particular configuration a capacity of 16 lines and 18 extensions. Note that two of the extensions are a Hotline phone and a doorphone, which do not use primary lines. Although your

configuration may differ, this example shows various devices connected to 10 of the 18 extensions. The circled numbers in the figure refer to the following list, which gives a brief description of the equipment components.

■

Equipment Controller

The equipment controller in this example contains both the primary and the expansion carriers, plus these components:

■

Backplanes. The backplanes distribute power to the premises equipment and connect the modules.

206 Modules. Each 206 module has jacks for two lines and six extensions.

400 Modules. Each 400 module provides four line

jacks but no extensions. Notice that each 400 module

is installed to the right of a 206 module.

Primary Processor Module. The primary processor module manages the components connected to the equipment controller. The following auxiliary equipment jacks are on the processor module:

■

PAGE. A loudspeaker paging system plugs directly into this modular jack. The premises equipment is compatible with any AT&T paging system, including the AT&T PagePac6® Plus shown here.

SMDR. A call accounting device or printer connects to this jack using an AT&T 355A or 355AF adapter. AT&T’s 572 serial printer is shown here.

MUSIC ON HOLD. An AT&T Magic on Hold® system is connected to this jack to provide customized music and messages for callers on hold. Other types of audio equipment (including a CD player, cassette player, or stereo receiver) can be connected with an audio cord and RCA phono plug.

Expansion Processor Module. The expansion processor module extends the primary processor

module’s management capabilities to the modules in the expansion carrier.

Line Jacks. All four jacks on each 400 module and the top two jacks on each 206 module connect to Centrex lines.

Extension Jacks. Inside wiring for telephones and

other telecommunications equipment connects to the

bottom six jacks on each 206 module.

Network Interface Jacks. These jacks provide

access to Centrex lines. Each Centrex line is connected to the equipment controller by plugging one end of the telephone Iine cord into one of these jacks, and the other end into a line jack on a 206 or 400 module.

Expansion Cable. The expansion cable connects the primary processor module to the expansion processor

module.

Extensions

This example shows MLS- and MLC-model phones and

industry-standard devices connected to the extension jacks in the equipment controller by way of the building’s inside

wiring.

Extension Jack 10: These devices are connected:

MLS-34D Display Phone. Typically, the

receptionist on extension 10, called the primary programming extension, has an MLS-34D phone.

AT&T 267F2 Bridging Adapter. This adapter permits the connection of two devices—in this example a standard touch-tone phone and an MLS-34D phone—on one extension jack. This is called a combination extension. (You cannot connect two MLS- or MLC-model phones.)

Standard Phone.

The MLS-34D phone on extension jack 10 will not work during a power failure; therefore, the receptionist can use the standard phone.

Extension Jack 11: MLS-34D Display Phone.

Another MLS-34D is connected to extension jack 11, or the backup programming extension. You can program the premises equipment from this extension while the

phone at extension jack 10 is free to handle calls.

NOTE:

An MLS-34D or MLS-12D is required for programming at extension jack 10 or 11, or both. Use an MLS-12D only if there are no MLS-34D phones installed at your site.

Extension Jack 12: Fax Machine and Standard Phone. A fax machine and standard phone are

connected together on this extension. This setup lets you share the fax line with a telephone. Alternatively, you can use an MLS- or MLC-model phone at another extension to monitor the fax machine (see page 7-2).

Extension Jack 13: MLS-12D Phone and Bell.

A loud

bell, to provide loud ringing in a noisy area, is

combined with an MLS-12 phone.

Extension Jack 14: MLS-12 Phone. This phone is

similar to the MLS-12D telephone (see extension jack

13), but it has no display.

Extension Jack 15: MLS-6 Phone and Answering Machine. An MLS-6 phone and an answering machine

are connected to this extension. (See page 7-5). Extension Jack 16: Standard Phone. A standard

touch-tone phone (such as you might have in your home) is connected to this extension jack.

Extension Jack 17: MLC-6 Cordless Phone. An AT&T MLC-6 cordless telephone is connected to this extension. It works like the corded MLS-6.

Note how the Hotline phone and doorphone are connected to the last available extension jacks on the last installed 206 module in the equipment controller:

Extension Jack 26: Hotline—Standard Phone.

When

the handset of this phone is lifted, another phone rings. Extension Jack 27: Doorphone. A doorphone is

installed at the building entrance. When someone at the entrance presses the doorphone button, the designated extensions (five maximum) in the office alert.

Installing the Carriers and Modules

206 Module

Backplane

A) Hold the backplane against the

wall. (If you are also installing the expansion carrier, plan to install it to the right of the primary carrier, leaving 6” to 24” between carriers.) Using the four screw keyholes in the backplane as a template, mark screw locations on the wall. Start four #12 screws,

leaving the screw heads approxi-

mately 1/4” away from the wall. Slip the backplane onto the screws and tighten them. B) If you are mounting the expansion carrier, repeat this step.

Lights

If you have installed both carriers, plug the ends of the expansion cable into the two processor modules and tighten the screws. Route both ends of the cable through the hooks on the fronts of the modules.

NOTE: The colored plastic filters on the expansion cable should rest just below the hooks.

Primary Processor Module

A) Slide the primary processor module into the center slot of the primary carrier backplane. Push slowly but firmly until the module locks into place with two snaps, so that it is attached to the rear of the backplane and held by the locking tab on the bottom of the slot. Do not force the module. If it does not insert easily, remove the module, clear any obstruction, and reinsert. B) If you have an expansion carrier, slide the expansion processor module into its center slot until the module locks into place.

Main Circuit Breaker

A) Make sure the main circuit breakers on both carriers are off (pulled out). B) Press the AC power cord firmly into the power jack on the top right rear of the backplane until it locks into place. Plug the other end of the power cord into a grounded three-prong wall outlet not controlled by a switch. Repeat for the expansion carrier, plugging its cord into the same wall outlet. C) Push in the main circuit breaker for the expansion carrier first, and then push in the main circuit breaker on the primary carrier.

Slide the first 206 module into the

leftmost slot of the primary carrier

backplane. (The system will not work if a 206 module is not installed in this slot.) Going from left to right, install a 206 module first, then a 400 module. Each 400 module must be to the right of a 206 module.

WARNING:

There are no customer-serviceable components inside the modules or

backplane. Hazardous voltages

within. DO NOT OPEN THE

MODULES!

Check all green lights on the fronts of the modules to make sure they are lit. If a single light is out, pull out the main circuit breakers, reseat the module, then push in the main circuit breakers (as you did in Step 5C). If multiple lights are out, check to see that the modules are installed in the right order. If they are, pull out the main circuit breakers, reseat the leftmost module of the ones that were out, then push in the main circuit breakers. If the lights are still out, call the Helpline.

Using the Equipment with Centrex Services

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).

Using the Equipment

Page 43

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 jack 10, which is assigned all of the lines in your system, to permit a

receptionist to answer calls for users if they do not pick up immediately. (For

more information on call coverage, see “Call Coverage Options” in Chapter 4.)

By default, the primary line for an extension is set for immediate ringing and any

secondary lines are set for delayed ringing. When a call comes in on a line, it

rings immediately at the extension where the line is assigned as a primary line; after about 20 seconds it also begins to ring at any extensions where the line is assigned as a secondary line (for example, at the receptionist’s extension).

NOTE:

The equipment controller passes Centrex ringing patterns through to each

phone (for example, Centrex ringing patterns are usually different for outside and inside calls).

Centrex Line and Extension Numbers

Each Centrex line is identified by a seven-digit telephone number (for example, 555-1212). When someone outside your system calls a Centrex telephone

number (an outside call), the call rings at the extension where that number is

assigned as the primary line.

Users who are on the same Centrex system can generally dial another extension

(an inside call) using the Centrex extension number. The Centrex extension

number is typically the last digits of the telephone number—the number of digits

is determined by the local telephone company, but in most cases the last four or five digits of the telephone number are used. For example, the Centrex

extension number for 555-1212 might be 1212 or 51212. (Some Centrex

systems may also provide a one-or two-digit “Centrex extension ID” that can be

used to dial other extensions.)

Jack Numbers for Extensions and Lines

Although users will identify extensions by the Centrex extension number, the

equipment controller tracks lines and extensions using two other numbers,

based on the physical connections at the equipment controller. When your

premises equipment was installed (see Chapter 2), the following connections were made:

■

Each Centrex line comes into your building from your local telephone company and terminates at a network interface jack; each network

interface jack is then connected to a line jack on the equipment controller. Each line jack on the controller is identified by a line jack number. Line jack numbers run from 01 through 24 (if you have the maximum number of lines that can be used with your premises equipment).

Using the Equipment

3-3

Page 44

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 jack numbers and extension jack numbers are required for many of the programming procedures that you use to customize your premises equipment.

Figure 3-1 shows line jack numbers and extension jack numbers in relation to telephone numbers and Centrex extension numbers in a very small (three-telephone) system. The three lines in this example (555-1000, 555-1001, and 555-1002) use the last four digits of the phone number as the Centrex extension number. The first line has Centrex extension number 1000; it is connected to the first line jack on the equipment controller (line jack 01), and

serves as the primary line for the phone connected to extension jack 10. The other two lines are connected to line jacks 02 and 03, and provide primary lines for the phones connected to extension jacks 11 and 12, respectively.

NOTE:

Figure 3-1 shows only primary line assignments. By default, the equipment controller assigns all lines to the phone connected to extension jack 10, but only the first line is primary.

Using the Equipment

Page 45

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.

To complement your Centrex services, your equipment controller provides

additional features. You can use Table 3-1 to identify the services you have on your Centrex system; then see Chapter 4 for more information on equipment features you may want to add to your system.

Centrex services are supplied by your local telephone company; see the Centrex documentation provided by your local telephone company for more specific information on the services available with your system. Also, be aware that the names of services may vary depending on the supplier. You can use the

System Planner to record the services available on each line in your system.

NOTE:

Many Centrex services are accessed by pressing the switchhook on a standard

phone, then dialing a Centrex feature code. On an MLS- or MLC-model phone,

however, use the Recall feature to send a timed switchhook flash and then dial the Centrex feature code—see Chapter 5 for instructions on programming the Recall feature on a button and Chapter 6 for instructions on using the Recall feature. Pressing the switchhook on an MLS- or MLC-model phone disconnects the current call instead of sending a switchhook flash.

(See the Centrex documentation provided by your local telephone company for specific instructions; but where instructions for Centrex conference calling or call transfer say “press the switchhook on your phone,” press the [

Conf

] or [

Transfer

] button instead.)

Auto Dial buttons let you program a sequence of digits onto a programmable phone button, and then dial the digits simply by pressing the programmed button. You can use Auto Dial buttons to store the codes you use to access Centrex services, or to store frequently-dialed phone numbers for one-touch dialing.

3-6

Using the Equipment

Page 47

You can store dialing sequences on two types of telephones:

■

On MLS- and MLC-model phones you can store feature codes and phone numbers on any of the programmable buttons, as long as no lines are assigned to the buttons. MLS- and MLC-model phone buttons can be programmed centrally from an MLS-34D or MLS-12D phone connected to extension jack 10 or 11, or directly at a user’s extension. In addition to Centrex feature codes and phone numbers, you can program MLS- and MLC-model phone buttons with codes for features that are available with your premises equipment; see “One-Touch Access to Equipment Features” in Chapter 4 for instructions.

On industry-standard phones with programmable buttons (feature

■

phones), you can store feature codes and phone numbers on any programmable buttons. Buttons on feature phones must be programmed at the user’s extension.

Storing Centrex Feature Codes on Auto Dial Buttons

To store a Centrex feature code on an Auto Dial button, first make sure the service is available on the Centrex line for the extension being programmed. Then store the Centrex feature code on the button. (For MLS- and MLC-model phones, use the instructions on pages 5-15 and 5-16; for feature phones, follow the instructions provided with the phone.)

NOTE:

When a Centrex feature code is stored on a programmable button on an MLSor MLC-model phone, the lights next to the button do not show when the feature is active.

Storing Phone Numbers on Auto Dial Buttons

You can store outside telephone numbers or Centrex extension numbers on Auto Dial buttons. Pressing the button automatically dials the number. Outside numbers and Centrex extension numbers can be stored on any phone with

programmable buttons.

To program an outside telephone number, store the complete number, including the dial-out code (“9” on most Centrex systems) if your Centrex system requires it for outside calls. For example, to dial 201 555-1212, store 9 1 201 555 1212 on the Auto Dial button.

NOTE:

If a dial-out code is required for outside calls, this code should be programmed for the premises equipment using the PBX Dial-Out Code (#106) procedure. See page 5-10.

If you store a Centrex extension number on a button, you can use the button to call the extension simply by pressing the button or to help in transferring the call. (For instructions on using Centrex call transfer, see the Centrex documentation provided by your local telephone company.)

Decisions for Customizing Your System

Overview

As discussed in Chapter 3, the default settings for your premises equipment are designed to complement your Centrex services. However, you may wish to customize your premises equipment to fit the needs of your business more exactly.

This chapter describes some equipment features that can provide added

benefits to your system, as well as some settings that you may wish to change to

tailor your phone system to your needs. Use the material here to help you make

choices about the way you want your system to work and identify the relevant programming procedures; then see Chapter 5 for detailed programming instructions.

NOTE:

The System Planner for your premises equipment provides an ongoing record of your equipment setup and programming. If you change the programming for your premises equipment after installation, record any changes in your System

Planner. This ensures that you always have a current record of your equipment programming.

Call Coverage Options

This section describes your options for providing call coverage when the user at

an extension is not available to take calls. The following options are discussed:

■

Central Call Coverage by a receptionist (the default) Centrex Call Coverage using Centrex features such as call forwarding or

■

voice mail

■

Local Call Coverage by another extension Coverage by an answering machine

■

Additional options for extensions that provide call coverage.

■

An extension that picks up calls on another extension’s line is referred to as a covering extension. An extension whose calls can be picked up by another extension is referred to as a covered extension.

Central Call Coverage

Central Call Coverage—the default call coverage setup—lets a central receptionist answer calls that are not picked up by the user at the dialed extension. When a call comes in on a line, it rings first at the phone where the line is assigned as a primary line, but if the user at that extension does not pick it up, it also rings at the receptionist’s phone.

NOTE:

For a central receptionist, install an MLS-34D phone (which has 32 line/programmable buttons). This phone can easily handle the system maximum of 24 lines and still have eight programmable buttons available for features.

Figure 4-1. Central Call Coverage

Setup for Central Call Coverage is simple, because the equipment controller automatically assigns all lines to the receptionist’s phone (the phone connected to extension jack 10). The Centrex line connected to line jack 01 on the equipment controller is assigned as the primary line; all other lines are assigned as secondary lines. This arrangement lets a receptionist cover all of the lines in your system.

Table 4-1 shows the equipment programming settings that are needed for Central Call Coverage. The first column shows the name of the programming procedure or function. System Programming procedures, which determine how the equipment controller handles lines and extensions, include the procedure number in parentheses—for example, “Line Assignment (#301).” Telephone Programming procedures, which affect the operation of individual extensions, show only the name of the procedure.

Centrex Call Coverage

Centrex Call Coverage uses Centrex services—such as call forwarding or voice

mail—to provide coverage for unanswered calls.

To set up Centrex Call Coverage, remove all secondary lines from the

receptionist’s phone (the phone connected to extension jack 10). You may also

wish to program the codes for Centrex coverage services onto programmable

phone buttons, to provide one-touch access to those services.

Table 4-2 shows the settings you should change to switch from Central Call

Coverage to Centrex Call Coverage. The first column shows the name of the programming procedure or function. System Programming procedures, which

determine how the equipment controller handles lines and extensions, include the procedure number in parentheses—for example, “Line Assignment (#301).” Telephone Programming procedures, which affect the operation of individual

extensions, show only the name of the procedure. (See Chapter 5 for more

information on programming.) The remaining columns show the required and optional settings for this call coverage setup.

To provide one-touch access to Centrex coverage services, program the Centrex feature codes onto Auto Dial buttons.

Local Call Coverage enables co-workers to cover each others’ phones. This coverage setup can eliminate the need for a central receptionist.

NOTE:

MLS- or MLC-model phones are recommended at covering extensions, so that

the user at a covering extension can see which line is ringing when a call comes

in. Figure 4-2 shows one example of how Local Call Coverage works.

Centrex extension 1000 (shown in Figure 4-2) is a covering extension for three

other extensions. It has a primary line (-1000) and three secondary lines (-1001,

-1002, and -1003). With the secondary lines set for “delayed ring,” calls to those lines begin ringing at extension 1000 after about 20 seconds. This setup might be useful for someone who serves as a backup answering position for a department. (Alternatively, each of these four extensions could be assigned secondary lines for all the other members of the extension group, so that any member of the group could cover calls for any other member.)

The phone at extension 1007 (see Figure 4-3) has a primary line plus a single secondary line. With the secondary line set for “immediate ring,” all calls on the secondary line ring immediately at the covering extension. This setup is useful when someone screens all calls on a line, transferring them only when the user at the covered extension wants to take the call.

Figure 4-3. Local Call Coverage: Immediate Call Answering

To set up Local Call Coverage, remove secondary lines from the receptionist’s phone (the phone connected to extension jack 10) and assign them to covering extensions as needed. (To have the receptionist keep covering some lines, remove only the lines that will be covered by other extensions.)

Adjust line ringing for primary and secondary lines to fit the type of call coverage you want. For example, set a primary line to “immediate ringing” (the default setting) if calls should ring first at the covered extension. Then set the line to “delayed ring” or “no ring” at the covering extension.

Button-Down Mode (#723)

adjusts ringing for all phones. Designed for people who are accustomed to 1A Key systems, this setting means that calls ring only on an extension’s primary line (or on the intercom). When a call comes in on a secondary line, the lights next to the line button flash, but the call does not ring. The person at the covering extension must press the line button to answer the call. This prevents users from accidentally answering incoming calls on secondary lines when they are trying to place calls on their primary lines. At the

phone connected to extension jack 10, lines ring according to defaults (“immediate ring” for the primary line and “delayed ring” for secondary lines). If

you are combining Local Call Coverage with button-down operation, you may want to adjust Line Ringing at covering extensions so that some secondary lines ring. (To put the system into button-down mode, see page 5-10.)

Table 4-3 shows the settings you must change to switch from Central Call Coverage to Local Call Coverage. The first column shows the name of the programming procedure or function. System Programming procedures, which determine how the equipment controller handles lines and extensions, include the procedure number in parentheses—for example, “Line Assignment (#301).” Telephone Programming procedures, which affect the operation of individual extensions, show only the name of the procedure.

Call Coverage with Answering Machines

Personal answering machines are a call coverage option that can be used alone

or combined with other call coverage solutions. An answering machine can be

combined with a telephone at any extension, using a bridging adapter as described on page 2-5. With this setup, an answering machine covers all ringing calls on an extension (on both primary and secondary lines). For more

details on connecting personal answering machines, see page 7-5.

Additional Options for Covering Extensions

The following equipment features can be especially useful when they are

programmed onto equipment feature buttons for covering extensions. Programming procedures are explained in detail in Chapter 5.

■

Fax Management.

If you are connecting a fax machine to an extension in

your system, first use

Fax Machine Extensions (#601)

to identify the

extension where the fax machine is installed. Then, on the covering extension’s phone, program a one-touch Intercom Calling button with the extension jack number for the fax machine. This enables the person at the covering extension to see whether the fax machine is busy or not responding (for instance, out of paper). Use

Line Assignment (#301)

to remove the fax line from the receptionist’s phone. For more information on setting up fax machine extensions, see page 7-1.

Message Light On

and

Message Light Off

can be assigned to programmable buttons, to turn the message lights on MLS- or MLC-model phones on and off. (To use a button programmed with one of these features, you must press that button and then dial the extension jack

number.)

Use

Line Access Restriction (#302)

if you wish to control outgoing calls

on secondary lines. For more information, see page 4-16.

Night Service

must be turned on and off at the receptionist’s phone (the

■

phone connected to extension jack 10 on the equipment controller). For more information about Night Service, see page 4-13.

One-Touch Access to Equipment Features

As discussed in “One-Touch Access to Centrex Services” in Chapter 3, you can store any dialing sequence—such as Centrex feature codes or frequently-dialed phone numbers—on programmable phone buttons. In addition, you can program the buttons on MLS- and MLC-model phones with the codes for features that are available with your premises equipment.

MLS- and MLC-model phone buttons can be programmed centrally from an MLS-34D or MLS-12D display phone connected to extension jack 10 or 11, or directly at a user’s extension. For equipment features that require an extension or line jack number, you should program the features centrally, storing the feature codes on programmable buttons—this lets people use the features simply by pressing buttons, without needing to remember the jack numbers. (See Appendix B for a complete discussion of equipment features that require extension or line jack numbers.)

4-10

Customizing Your System

Page 59

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 show status information for Centrex features.

Information on programming equipment features is provided on page 5-16. Here are some specific features you might want to store on programmable

buttons:

■

Voice paging of specific extensions Voice paging of Calling Groups

Extension jack numbers for frequently-dialed extensions inside your

system (so that users can call with one touch, talk without tying up their

primary lines, and monitor the status of that extension). Message Light On and Message Light Off Privacy and Do Not Disturb, which require buttons with lights Recall, to send a switchhook flash for accessing Centrex features while

on a call.

Intercom Calling

If you store an extension jack number on a programmable button at an MLS- or MLC-model phone, you can use the button as a Direct Station Select (DSS) button, to call the extension with one touch, simply by pressing the button. This enables you to call the extension using the intercom, so you can make an inside call without tying up your primary line (as well as the primary line for the person

you are calling). (See Appendix B for details on intercom calling.)

In addition, the lights next to the button act as Busy Lamp Fields (BLF) that show calling activity for the extension:

Idle (no lights)

■

Busy (red on)

■

Calling you using the intercom (green flash).

If the extension is identified as a fax extension, the button also shows a red broken flutter when the fax is not responding (for instance, when it is out of paper).

This equipment feature is called Call Viewing. You may wish to use Call Viewing

at any covering extension (for example, at the receptionist’s phone), so the person at the covering extension can monitor calling activity at covered extensions by looking at the Intercom Calling buttons. Since Call Viewing requires buttons with lights for each extension covered, an MLS-34D, MLS-12,

or MLS-12D phone is recommended for this function.

Customizing Your System

4-11

Page 60

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.

Paging

Two equipment features enable you to page system extensions. For ease of use, you should store these features on the programmable buttons of MLS- or

MLC-model phones, so that a user can page a phone or group of phones simply by pressing the programmed button.

The following types of paging are available:

Paging over an optional loudspeaker paging system,

which may be

■

connected to the equipment controller. You access the loudspeaker by dialing an equipment feature code, which can be programmed onto a button on an MLS- or MLC-model phone.

Paging over MLS-model phones,

which have built-in speakers, provides

■

an inexpensive alternative to a loudspeaker paging system. By dialing the appropriate feature code, you can page an extension (Voice Paging) or a Calling Group (Group Paging). Paged extensions beep (at any extension

that has an MLS-model phone) to indicate that the speaker has been turned on; then your voice is heard over the speaker. When a caller picks up the page (by picking up the handset or pressing [

Mic

]), the page becomes an intercom call between the person who paged and the person who picked up. (Because it is an intercom call, the call does not tie up the user’s primary line.)

The feature code for Group Paging, or for paging a particular extension, can be stored on a telephone button for one-touch dialing. (Paging an extension requires that the extension jack number be stored on the telephone button.)

If you are busy on a call when someone tries to voice page your extension, your phone rings instead of turning on the speaker for the page. If you try to voice page an extension where a standard phone or MLC-6 is connected, the phone rings.

Example:

A car dealership puts all extensions for the sales staff into a Calling Group. To talk to salespeople, the sales manager simply presses a programmed button on an MLS- or MLC-model phone. A paging intercom call goes to the Calling Group. The phones’ primary lines remain free for incoming calls.

To set up loudspeaker paging:

Connect a loudspeaker paging system to the primary processor module

■

of the equipment controller, as described on page 2-13.

■

To let a user access loudspeaker paging with one touch, install an MLSor MLC-model phone at the user’s extension and program a button with the feature code for loudspeaker paging (see page 5-16).

To set up paging to MLS-model phones:

■

Install MLS-model phones in locations where you want employees to hear

voice-paging announcements.

To set up group paging, first use

Calling Group Extensions (#502)

to assign extensions to Calling Groups. Exclude extensions with fax machines, Hotline phones, doorphones, or other auxiliary equipment from Calling Groups. You can set up as many as four Calling Groups.

Program paging buttons on MLS- or MLC-model phones, so that people

can easily page groups or individuals. (Program these features onto

buttons so that users will not have to remember group numbers or extension jack numbers.) See page 5-16 for programming information.

Optional Features for Premises Equipment

In addition to the features you have available through Centrex, you can use

equipment features to support your company’s call handling. This section

discusses some of the most useful features; for a complete listing, see Table 4-6

on page 4-25. Programming instructions are in Chapter 5.

Night Service

The Night Service feature allows you to change the way a group of extensions operates after normal business hours. When Night Service is turned on, all

incoming calls will ring immediately the extensions in the

Night Service

Group (#504),

even if Line Ringing for those extensions is set for “delayed ring”

or “no ring” during normal daytime use. For Night Service to work properly, all

lines should be assigned to the extensions in the Night Service Group.

Example:

The security guard at Company X has a standard single-line phone with all of the lines for the company assigned to it. The secondary lines are set to “no ring,” so that the guard only receives calls on the primary line for the extension during the day. When Night Service is on, however, all lines ring immediately at the security desk, to provide backup call answering when there

is no one available in the office.

Table 4-4 shows the programming settings that must be entered to set up Night Service. The first column shows the name of the programming procedure or function. System Programming procedures include the procedure number in

parentheses—for example, “Line Assignment (#301).” The remaining columns

show the required and optional settings for Night Service.

If you wish to restrict calling from Night Service Group extensions, use

System

Password (#403)

to specify the system password. If a password is programmed, users in the Night Service Group must enter it before dialing outside telephone numbers or Centrex extension numbers (with some exceptions, described on page 5-13). Intercom calls can be made without using the password (see Appendix B). The password must be entered to turn Night Service on or off. A System Password cannot be entered from a standard phone

or from an MLC-6 cordless phone.

4-14

Customizing Your System

Page 63

■

The equipment controller can store a maximum of 80 System Speed Dial

numbers (dial codes 20-79).

System Speed Dial numbers must be programmed from an MLS-34D or MLS-12D display phone at extension jack 10 or 11.

If you must include a dial-out code before dialing an outside number,

include the dial-out code in the programmed Speed Dial number.

It is recommended that you do not store Centrex feature codes as System Speed Dial numbers. (If the equipment controller sees an asterisk in the Centrex feature code, it will interpret the number as a Marked System Speed Dial number and will not dial the asterisk.)

Appendix A provides a form on which to record Speed Dial numbers. You should record all System Speed Dial numbers on the top of that form and give a copy to each user with an MLS- or MLC-model phone.

You may decide to use Centrex speed dialing on all lines for the numbers that all users need often; Centrex speed dial numbers can be dialed from both standard phones and MLS- or MLC-model phones.

Frequently-dialed numbers can also be programmed onto Auto Dial buttons on MLS- or MLC-model phones for even faster one-touch dialing.

Personal Speed Dialing

Personal Speed Dial numbers are available only at the extension for which they are programmed (for users who have MLS- or MLC-model phones). The following notes apply to Personal Speed Dial numbers:

■

Personal Speed Dial numbers are stored in an extension’s memory and are for the private use of that extension.

Each extension can have a maximum of 20 Personal Speed Dial numbers (dial codes 80-99).

Personal Speed Dial numbers can be programmed from an MLS-34D or MLS-12D phone at extension jack 10 or 11, or from the user’s extension.

Personal Speed Dial numbers do not have to be used to store telephone numbers. Like programmable buttons, they can also be programmed to provide faster access to equipment and Centrex features.

If you must include a dial-out code before dialing an outside number,

■

include the dial-out code in the programmed Speed Dial number.

Users can record their Personal Speed Dial numbers on the Quick Reference cards for their phones or on the bottom of the Appendix A “Speed Dial Numbers” form.

Calling Restrictions

Once a caller has access to a Centrex line, Centrex can provide dialing restrictions for the line. Centrex restrictions apply to all appearances of a line—controlling calling on all phones that have that line assigned, whether the line is assigned as a secondary line or as a primary line.

The dialing restrictions that are available through your equipment controller can provide additional flexibility, letting you control a particular extension’s access to

Customizing Your System

4-15

Page 64

a Centrex line—for example, permitting all calls on a line at the extension where

it is assigned as a primary line while preventing outgoing calls on the line from an extension where it is assigned as a secondary line. In addition, equipment

dialing restrictions can provide some of the protection provided by Centrex

restrictions, restricting dialing on a specific Centrex line assigned to an extension, restricting dialing for all lines assigned to an extension, or overriding equipment dialing restrictions. (Users can always place and receive intercom calls, regardless of the equipment dialing restrictions placed on their extensions.)

Refer to Table 4-5 on page 4-20 for a summary of the dialing restrictions and permissions that are available through your equipment controller.

NOTE:

If you have Centrex dialing restrictions on a line and also program equipment dialing restrictions for the line or an extension where the line is assigned, both the Centrex and equipment restrictions will apply to the line or extension. However, equipment dialing permissions will not override Centrex restrictions.

Restricting Line Access

As noted previously, Centrex dialing restrictions apply to all appearances of the

line to which they are assigned. If you wish to customize the restrictions for a line that is assigned to more than one extension, use the System Programming

Line Access Restriction (#302)

procedure to limit a particular extension’s access to a Centrex line. For example, you may wish to set an extension’s secondary lines to “incoming only.” This prevents the person at a covering extension from making outgoing calls on another user’s primary line. The

following options are available for Line Access Restriction:

No restrictions.

■

Incoming only. The person at the extension can receive but not place

■

calls on the line. If you restrict a line on an extension to incoming calls only, the user cannot get a dial tone on that line.

■

Outgoing only. The person at the extension cannot receive calls on the

line, but can place calls.

No access. The person at the extension can see the status of the line (by

■

looking at the lights next to the line button), join a call, and pick up a held call. However, the user at the extension cannot place or receive calls on the line.

For programming instructions for Line Access Restriction (#302), see page 5-11.

Restricting Dialing for All Lines at an Extension

The Line Access Restriction procedure controls an extension’s access to a line. Once an extension has access to a line, what it can dial is controlled by Outgoing Call Restriction, Disallowed Phone Number Lists, and (if a System

Password is defined) Night Service. These last three restrictions are similar to

those provided by Centrex; but the Centrex restrictions are by line (for all extensions the line is assigned to) and the equipment restrictions are by

extension (for all lines assigned to the extension).

4-16

Customizing Your System

Page 65

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 Centrex line, you can use the following procedures to control calling for all lines to which the extension has access:

■

Outgoing Call Restriction (#401)

provides the following choices:

■

No restriction allows outside calls to long distance and local numbers, and inside calls.

Local only allows outside calls to local numbers, and inside calls

■

(make sure the Toll Call Prefix is set properly, using procedure #402).

■

Inside only allows inside calls only.

Disallowed Phone Number Lists (#404)

creates lists of numbers that

■

cannot be dialed. The numbers on a Disallowed List can be entire telephone numbers, or numbers of a certain type (such as all numbers in a particular area code). You can store as many as four different lists of up to 10 numbers each. For information on entering telephone numbers into lists, see “Entering Telephone Numbers into Lists” on page 4-18. (For

programming information, see page 5-12.) After you create the Disallowed Lists, use the

Disallowed List

Assignments (#405)

procedure to assign one or more of the lists to a

specific extension.

Night Service

(with a System Password defined) restricts calling on

■

Centrex lines by all extensions in the Night Service Group. Night Service (with or without a password) also causes after-hours calls to ring immediately at the extensions in the equipment Night Service Group,

regardless of Line Ringing during normal day operation. See page 4-13

for details on Night Service.

Overriding Dialing Restrictions

The following programming procedures provide ways to override all equipment dialing restrictions, except those imposed by Line Access Restriction (the

extension must have access to a Centrex line):

Emergency Phone Number List (#406)

defines a list of up to ten

■

numbers that can be dialed from any extension in the system. A typical Emergency number is 911. For information on entering telephone numbers into lists, see “Entering Telephone Numbers into Lists” on page 4-18. (For programming information, see page 5-12.)

NOTE:

A variety of factors influence the effectiveness of dialing restrictions. Avoid

putting 800 numbers in your Emergency List. If you need to allow restricted users to dial 800 numbers, put those numbers in an Allowed Phone Number List (see page 4-18).

Customizing Your System

■

Marked System Speed Dial Numbers

can be dialed from any extension. System Speed Dial numbers are telephone numbers that a user can dial automatically by pressing [

Feature

] (or [ # ] on a standard phone), followed

by a two-digit code. “Marking” a System Speed Dial number when the number is programmed lets any user in the system dial it, overriding any equipment dialing restrictions for the extension.

System Password (#403)

creates a password that, when entered at any

■

MLS-model phone, overrides equipment dialing restrictions for the duration of a call. This means that a person who knows the password can make a call from a restricted extension. If you define a System Password, turning on Night Service also restricts calling for the Night Service Group. See page 4-13 for details on Night Service.

You can use the following procedure to override all equipment dialing restrictions, except Line Access Restriction and Night Service with a System Password:

■

Allowed Phone Number Lists (#407)

allows you to create lists of

numbers that specific extensions are allowed to dial. Even if an

extension’s settings for Outgoing Call Restriction and Disallowed Phone Numbers would normally prevent the extension from dialing a number, defining the number as an Allowed Phone Number lets the extension dial it. (For example, if you put 900 numbers on a Disallowed List but want users to be able to call a specific 900 technical support hotline, put that number in an Allowed List.) For information on entering telephone numbers into lists, see “Entering Telephone Numbers into Lists” on page 4-18. (For programming information, see page 5-12.)

The equipment controller stores as many as four different Allowed

Lists of up to 10 numbers each. After creating Allowed Lists, use the

Allowed List Assignments (#408)

procedure to assign one or more of

the lists to a specific extension.

Entering Telephone Numbers into Lists

This section explains how to enter telephone numbers into Disallowed Phone

Number Lists, Allowed Phone Number Lists, and an Emergency Phone Number List.

To store a telephone number, dial the number as you would normally; but leave out the dial-out code if you must normally dial one to place outside calls.

However, for toll calls you should include a toll call prefix such as 1 or 0 (if you

must dial one to place toll calls) and the area code. For example, to prevent all calls to a specific area code, you need only enter the

toll call prefix and the area code in a Disallowed List. When a user at an extension to which the list is assigned tries to dial a number in that area code, the user hears a reorder tone (fast busy signal) as soon as they dial the area code, before they have a chance to dial the rest of the number.

When you store a telephone number in a list, you can also use the “wildcard” character to stand for any single digit in a phone number. To enter the wildcard character, press [

Hold

]; the wildcard appears as “!” on the telephone display. For example, if you want to prevent users from placing calls to any numbers beginning with 202, 212, 222, 232, 242, 252, 262, 272, 282, and 292, you can enter each number in a separate list entry, or you can combine them into one

Summary of Equipment Dialing Restrictions

Table 4-5 summarizes the equipment dialing restrictions and permissions, showing how they can be combined in a variety of ways to customize an extension’s dialing privileges. This table assumes that at least one Centrex line is assigned to the extension for which you are creating dialing restrictions.

Dialing Restrictions: An Example

The following example shows how the equipment controller checks dialing

restrictions and permissions when a user places a call. The controller checks

the number dialed against all the equipment dialing restrictions that apply to the

extension placing the call. When the number dialed passes a restriction, it goes to the next one, if necessary. When a number violates a restriction, the call is stopped and the user hears a reorder (fast busy signal) tone.

In this example, the user is dialing on a line that has Outgoing Call Restriction

set to “local only.” In addition, the extension has an Allowed Phone Number List that contains a “1800” entry. Notice that the equipment controller keeps checking the number until it finds a valid reason to complete the call or stop it.

Dial: 1 201 555-1212

Dial: 1 800 555-1212

Emergency Number?

No, keep checking

Marked System Speed Dial Number?

No, keep checking

System Password entered?

No, keep checking

Night Service on?

No, keep checking

Allowed Phone Number?

No, keep checking

Yes, complete the call (if there are no Centrex

restrictions)

Disallowed Phone Number?

No, keep checking

Outgoing Call Restriction violated?

Yes, call dropped and reorder tone given

NOTE:

If you have Centrex dialing restrictions on a line and also program equipment

dialing restrictions for the line or an extension where the line is assigned, both the Centrex and equipment restrictions will apply to the line or extension.

However, equipment dialing permissions will not override Centrex restrictions.

Auxiliary Equipment

You can use a variety of auxiliary devices with your phone system, either by connecting them directly to the equipment controller or by connecting them to extensions. This chapter includes information on auxiliary equipment that requires programming, including Hotline phones, loudspeaker paging systems, doorphones, call reporting devices (SMDR), fax machines, and music-on-hold sources. Chapter 7 includes further information about this equipment and

additional equipment that does not require programming (including answering

machines, modems, and credit card scanners). In addition, Chapter 2 includes information about connecting auxiliary equipment to your equipment controller. Programming procedures are explained in detail in Chapter 5.

Hotline Phones

The

Hotline (#603)

procedure allows you to identify Hotline extensions and alert extensions, so that when a person lifts the handset of a Hotline phone, the alert extension rings automatically. You can specify one alert extension for each Hotline phone, and you can designate as many Hotline phones as you wish. In addition, the loudspeaker paging system can be designated as the alert extension for a Hotline phone, so that a Hotline phone can be used to make announcements over the loudspeaker.

Example:

A market installs one Hotline phone at its meat counter. When a customer picks up the Hotline phone, the butcher’s phone rings. Another Hotline phone is installed at a cash register and the loudspeaker paging system is identified as the alert extension, so a sales clerk can pick up the Hotline phone to request a “price check” over the loudspeaker.

To set up a Hotline phone:

■

Doorphones

Connect the Hotline phone to the last available extension jack on the equipment controller. (A standard touch-tone or rotary phone is recommended at the Hotline extension.)

Use

Line Assignment (#301)

(see page 5-11) to remove the primary line assignment from the Hotline extension jack. If you do not remove the primary line assignment, the Hotline phone will not work.

Use the

Hotline (#603)

procedure (see page 5-13) to identify the extension where the Hotline phone is located; the same procedure identifies the alert extension (or loudspeaker paging system) that will be signalled when the Hotline phone is used.

Make sure the Hotline phone extension is not in the

Pickup Group

(#501), Calling Group (#502), Night Service Group (#504),

Hunt

Group (#505).

(See page 5-13.)

You can specify up to five extensions that are alerted when a visitor presses the button on a doorphone. If the alert extension is an MLS-model phone, the doorphone signal is a distinctive ding-dong to distinguish it from regular calls. The person who answers a doorphone call can then use his or her phone to speak to the visitor outside the office. You can install two doorphones if you need them. (If you install two doorphones, they each have a different signal at MLS-model phones.)

Example:

You can install a doorphone outside your building entrance (or in the

hallway outside your suite) to allow visitors to signal telephones inside the office

when the receptionist is not there and the front door is locked. To set up doorphones:

Connect the doorphone to the last available extension jack on the

■

equipment controller.

Use

Line Assignment (#301)

to remove the primary line assignment from

■

the doorphones’ extensions.

■

Use the

Doorphone Extensions (#604 and #605)

procedures to identify

the extensions on which doorphones are installed.

Customizing Your System

4-23

■

Use

Doorphone Alert Extensions (#606)

Make sure the doorphone extension is not in the

Pickup Group (#501),

■

Calling Group (#502), Night Service Group (#504),

Hunt Group

(See page 5-13.)

Call Reporting

Centrex may provide call reporting and accounting services. However, if you do

not subscribe to this service, you can install call accounting devices and

printers that allow you to print call reports. To get a better idea of the call reporting capabilities available with your premises equipment, see “Call Reporting Devices (SMDR)” on page 7-7.

To set up a call accounting device or printer for call reporting, install the equipment according to the directions on page 2-13. Then use

SMDR Record

Type (#608)

to specify the type of calls that you want to record for call reporting.

Fax Machines

Fax Machine Extensions (#601)

lets you identify an extension on which a fax machine is installed. If you also program the fax extension as an Intercom Calling button (by storing the extension jack number on a programmable button with a light), the button will show the status of the fax machine when it is in use or needs paper. Do not assign a fax machine’s primary line to any other extension. See “Fax Machines” on page 7-1 for more details on setting up and

using fax machines.

Music on Hold

Music on Hold (#602)

activates or deactivates an optional music-on-hold system, which can be connected to an RCA jack on the equipment controller (see page 2-13).

Overview

In Chapter 4, you prepared to customize the premises equipment and individual telephones to meet the needs of your business. This chapter explains how to use programming to accomplish that.

There are two types of programming that you can perform:

System Programming

lets you customize your premises equipment to

■

meet the needs of your business. You can program the premises equipment from the MLS-model display phone at either extension jack 10

or 11, allowing you to program from extension jack 11 (the backup

programming extension) while the receptionist at extension jack 10 (the primary programming extension) continues to handle calls. (An MLS-34D phone is required for programming if your premises equipment includes any MLS-34D phones; if not, you can use an MLS-12D phone.)

■

Preparation.

See page 5-4, “System Programming Procedures,” to

find out how you get ready for System Programming.

■

Instructions.

Detailed descriptions and step-by-step programming instructions, with defaults, are on pages 5-10 through 5-14. These tables are designed as a flowchart for initial System Programming; the features are listed in the correct order for programming the system after it is started up. (Troubleshooting features are indicated by a broken phone symbol. For more troubleshooting information, see page C-3.) System Speed Dial programming instructions are on page 5-14.

Telephone Programming

lets users customize their telephones to meet

■

their individual needs; for example, users can program available phone buttons for one-touch access to their most frequently used features and telephone numbers. Telephone Programming is performed from the phone at extension jack 10 or 11 using an MLS-34D or MLS-12D phone (called Centralized Telephone Programming), or from a user’s extension

using an MLS- or MLC-model phone (called Extension Programming).

Preparation.

See page 5-4, “Telephone Programming Procedures,”

to find out how you prepare for Telephone Programming.

Instructions.

To program a phone from extension jack 10 or 11, use

■

the instructions at the top of page 5-15. To program at the extension,

use the instructions at the bottom of page 5-16, then go to the appropriate box on page 5-16 for instructions on programming an individual feature.

Brief summaries of all programming procedures are also provided on the inside back cover of this book.

A system-wide setting that causes incoming calls on secondary lines to flash, but not ring. A user must press the line button down to pick up the call. This feature enables the equipment to imitate the way lines ring at extensions on key telephone systems, such as the 1A Key System.

A method of telephone programming that lets you program individual extensions in the system from an MLS-34D or MLS-12D phone at extension jack 10 or extension jack 11. Centralized Telephone Programming is an alternative to

On MLS- and MLC-model phones, programmable buttons can be used as Auto Dial buttons (for one-touch dialing of Centrex feature codes or telephone numbers) or equipment

feature buttons.

System

Designates the way the premises equipment works for your

Programming

business on a system-wide basis. System Programming requires an MLS-34D or MLS-12D phone and must be done

from extension jack 10 or extension jack 11.

Telephone

Customizes ringing or adds special dialing features for

Programming

extensions, to meet the needs of individual users. Telephone Programming can be done either centrally (see Centralized

Telephone Programming) or from the user’s own extension

(see Extension Programming).

System Programming Procedures

In general, you can program the premises equipment in one of two ways:

Direct Method.

With this method, you access a programming procedure

■

by dialing the code for that procedure.

■

Cycle Method.

With this method, you cycle through the procedures in

numerical order by pressing [

Next Procedure

] or [

Prev Procedure

] (see the programming overlays on pages 5-5 and 5-6). This method is best for programming the premises equipment for the first time or for changing a series of related settings.

NOTE:

You can be talking on the phone while you program. This is useful if you need to talk with someone at the AT&T Helpline about programming. However, you must call before you enter programming mode, and you must use the handset to talk, not the speaker and microphone.

Review the following two procedures before you start to program, as they may facilitate your programming task:

Button-Down Mode (#723)

adjusts ringing for all phones connected to

■

your equipment controller. Designed for people who are accustomed to 1A Key systems, this feature causes incoming calls on secondary lines to flash (but not ring). To pick up a call, a user must press the line button. This prevents users from accidentally answering incoming calls on secondary lines when they are trying to place calls on their primary lines.

Only the receptionist’s phone at extension jack 10 follows the premises equipment defaults (“immediate ring” for the primary line and “delayed ring” for secondary lines). The default for Button-Down Mode is “Not

Active.”

copies Automatic Extension Privacy and Abbreviated Ringing settings as well as Fax Machine extensions, equipment dialing restrictions, and group assignments from one extension to another; it does not copy line assignments, line ringing settings, or button programming—see page 5-11 for a list of the specific

programmed settings that are copied. To save time, you can program one extension for each type of phone connected to the equipment controller, and then use Copy Settings to program other phones of the same type. For example, you can program one MLS-12D phone and then copy its settings to other extensions that have MLS-12D phones.

Programming Overlays

System Programming requires a programming overlay placed over the phone’s dial pad.

During System Programming, the normal functions of several buttons on the display phone at extension jack 10 or 11 change. For example, the left [

Intercom

]

button becomes [

System Program

], the button used to enter System Programming mode. To identify these buttons while programming, place the appropriate programming overlay (provided with the premises equipment) on the dial pad of the phone at extension jack 10 or 11. Figures 5-1 and 5-2 show the programming overlays for the MLS-34D and MLS-12D phones, and explain what the special buttons do while programming.

Telephone Programming Procedures

Two methods can be used to program telephones:

■

Centralized Telephone Programming

from extension jack 10 or 11

Extension Programming

from an MLS- or MLC-model phone at the

■

extension being programmed.

During Centralized Telephone Programming, the display phone at extension

jack 10 or 11 takes on the characteristics of the telephone being programmed,

including any System Programming and the lines assigned to the phone. Make

sure the programming phone is as large as the largest phone connected to the equipment controller, because an MLS-12D phone cannot program an MLS-34D phone. When you enter Centralized Telephone Programming, green lights appear next to any line buttons that are already assigned so that you do not attempt to program over them.

Programming Telephone Buttons

Telephone buttons without lines assigned to them are programmable buttons. Programmable buttons that are used to store outside telephone numbers, Centrex extension numbers, or Centrex feature codes are called Auto Dial buttons, because pressing the button automatically dials the number stored on the button.

In addition, you can use programmable buttons to store equipment feature codes or extension jack numbers for one-touch Intercom Calling. These buttons are called equipment feature buttons. (The equipment features that you can

program onto buttons are described on page 5-16. Note that some equipment features require programming on a button with lights so that you can see whether a feature is turned on or off.)

NOTE:

If your business includes industry-standard feature phones with programmable

buttons, follow the directions for those phones in order to program any telephone numbers or Centrex feature codes that you want to make available for one-touch access. Feature phones may also support speed dialing for faster

access to Centrex services.

Figure 5-3 illustrates the MLS- and MLC-model phones: MLS-34D, MLS-12D,

MLS-12, MLS-6, and MLC-6. As you program buttons, mark their functions on the phone’s labeling sheet (see the examples in Figure 5-3).

Changing Settings after Installation

As your business grows or changes, you will probably need to change the way your premises equipment was originally programmed. The following sections describe some instances where such changes might be needed.

Changing the System Clock

You may need to change or reset the system clock for daylight saving time, after

a prolonged power failure, or after a complete equipment reset. To change the system clock, use the following procedures:

System Date (#101)

to set the month, day, and year

■

System Day (#102)

to set the day of the week

■

System Time (#103)

to set the hour and minute.

Adding Modules and Centrex Extensions

If you add new modules to your equipment controller after installation, you will need to identify new extensions and to change Hotline and doorphone extensions (if those devices are installed). Likewise, if you add a Centrex extension after installation, you must adjust programmed settings to accommodate the new extension. You may want to use Copy Settings (#399) to copy some settings—see page 5-11 for information on the programmed settings that can be copied with this feature. (If you are using new extensions for auxiliary equipment, see Chapter 7.)

Use the following procedures to adjust the programming for your premises

equipment when you add a module or an extension:

■

Line Assignment (#301)

lets you verify that the primary line is assigned to an extension that you added. If it is not, use this procedure to assign the line. (You can also use this procedure to assign a secondary line to the extension.)

Line Ringing

(Centralized Telephone Programming) specifies when a

primary or secondary line will start ringing at the extension.

Line Access Restriction (#302)

determines whether users on each of

the lines assigned to the extension can place or receive calls on the line.

Dial Mode (#201)

identifies a line as rotary or touch-tone.

■

Hotline Phone and Doorphone Extensions

Hotline phones and doorphones should be connected to the last available extension jacks on the last installed 206 module in the equipment controller. If you add modules to your existing configuration and you have Hotline phones or doorphones connected to it, you will need to move the equipment (see page 2-14) and change the following programming procedures:

Hotline (#603)

to identify the new Hotline extension.

■

Doorphone Extensions (#604 and #605)

to identify the new doorphone

extension(s).

Line Assignment (#301)

to remove the primary line from the new Hotline

■

phone and/or doorphone extensions.

NOTE:

Remember to reassign the primary lines to the extension jacks where Hotline phones and/or doorphones were previously installed.

System Programming Reference

System Programming changes settings for the system as a whole, or for individual lines or extensions. You can also use System Programming to set up dialing restrictions, define groups, and set up optional equipment. Button-Down Mode (#723) can be activated (if needed) before Line Ringing is set. Use Copy Settings (#399) to copy settings from one extension to another.

Using Telephones

Overview

This chapter explains how to use your telephones. It does not provide detailed

instructions about using your Centrex services. See the Centrex documentation provided by your local telephone company for information on Centrex services.

Terminology

The following terms are used in this chapter. In addition, you may wish to review the “Terminology” section of “About This Guide,” which defines basic terms

used throughout this guide, or the Glossary, which defines all terms.

Centrex

extension

number Combination

extension

Equipment feature

Equipment feature button

Inside call

A short code (or “Centrex extension ID”) that can be used to dial another extension within the Centrex system. Typically, this is the last digits of the Centrex telephone number.

An extension that has two devices connected to it using a special connector called a bridging adapter. Combination extensions can connect two industry-standard devices or an industry-standard device and an MLS- or MLC-model phone, but not two MLS- or MLC-model phones.

A feature provided by your equipment controller (as opposed to a service provided by Centrex).

A programmable telephone button on an MLS- or MLC-model telephone that enables you to access an equipment feature simply by pressing that button.

A call made from an extension inside the Centrex system to another extension inside the Centrex system, using the Centrex extension number.

Using Telephones

Intercom call

Outside call

Primary line

Secondary line

Standard

phone

A call that is made using the [

Intercom

] button on an MLS- or MLC-model telephone, to call another system extension without tying up primary Centrex lines.

A call made from outside the Centrex system to an extension

within the Centrex system, or from inside the Centrex system to a number outside the Centrex system. If your Centrex system uses a dial-out code (usually a “9”), you must dial it before you dial an outside telephone number.

The main Centrex line assigned to an extension, generally used to place and receive all calls for that extension. When a caller dials a phone number, the call rings immediately at the extension where the line is assigned as a primary line (unless line ringing is changed to let a user at another extension screen calls on the line). See also Secondary line.

A line assigned to an extension for call coverage purposes, generally with delayed or no ringing. When a call comes in

on the line, it rings first at the extension where it is assigned as the primary line; only if there is no answer does it ring at the extension where it is a secondary line. See also Primary line.

An industry-standard touch-tone or rotary phone such as you might have in your home. Some standard phones include special feature buttons for frequently-used calling functions.

MLS- and MLC-Model Telephones

MLS-and MLC-model telephones have some buttons and indicators in common. Refer to pages 6-4 and 6-5 for an explanation of where they are and how they

work. Call handling instructions for MLS- and MLC-model telephones and

industry-standard phones begin on page 6-12.

Ringing Patterns and Dial Tones

Your Centrex system determines the ringing pattern you will generally hear when calls ring at your phone. (For example, there may be different ringing patterns

for inside and outside calls.) If someone makes an intercom call to your phone,

you will hear a ring and a beep (ring BEEP . . . ring BEEP . . . ring BEEP . . .).

When making most calls, you will hear the Centrex dial tone, indicating that you

are connected with a Centrex line. (If you press [

Intercom

], you hear the intercom

dial tone. See Appendix B for information on using the intercom button.)

Lights

Each line button has a green light and a red light. The meaning of these lights

varies, depending on whether the button is used to access a line or is

programmed with an equipment feature or Intercom Calling number.

Switchhook and Recall

When you are on a call using an MLS- or MLC-model phone, pressing the switchhook disconnects you from the call. To access Centrex services when you are on a call, use the Recall feature to execute a timed switch hook flash (see page 6-12). You can program this feature onto a button on your telephone (see page 5-16). (Recall disconnects an intercom call.)

Using the Handset, Speaker, and Microphone

Every MLS-model telephone has a speaker, which you can turn on by pressing

[

Spkr

]. When the green light next to [

Spkr

] is on, the speaker is on.

MLS-34D, MLS-12D, and MLS-12 phones also have microphones. On these phones, pressing [

Spkr

] turns on both the speaker and the microphone. In

addition, you can turn just the microphone on and off by pressing [

Mic

]. When

the green light next to [

Mic

] is on, the microphone is on.

The call handling instructions in this chapter explain how to use the handset to

make and answer calls. However, if you prefer to dial and conduct calls without

lifting the handset, you can use the speaker and the microphone instead. Use the following techniques to make calls with the speaker and (if you have one) the microphone:

■

To make a call without lifting the handset, press [

Spkr

] to `get a dial tone; then dial the number, and you will hear the call ringing. If you have a microphone, it is turned on automatically when you press [

Spkr

] (if it is not on already); when the other party answers, you can talk without lifting the handset. On MLS-6 phones (which have no microphone), lift the handset to talk when the other party answers.

To turn off the microphone when you are using the speaker, press [

Mic

This will mute your voice so that the other party cannot hear you. If you are already on a call (on an MLS-34D, MLS-12D, or MLS-12 phone),

you can switch from the handset to the speaker and microphone by pressing [

Spkr

] and hanging up the handset. Conversely, if you are using the speaker and microphone and want to switch to the handset, lift the handset and the speaker and microphone will turn off.

Use the Hands-Free Answer on Intercom (HFAI) feature (on an MLS-34D, MLS-12D, or MLS-12 phone), to answer voice paging calls without lifting the handset (see Appendix B).
