System 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.
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.
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.
Features and Capabilities Your equipment controller supports the following features to complement your Centrex services: ■ ■ ■ Multiple line assignments, permitting more flexible call coverage.
Premises Equipment Figure 1-3 shows an equipment controller and MLS- and MLC-model telephones connected to it. A brief description of each component follows the figure.
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.
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.
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 yo.
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.
■ ■ ■ ■ 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.

Using the Equipment with Centrex Services 3 Overview This chapter explains how your premises equipment works in conjunction with your Centrex services. The following topics are discussed: ■ Line assignments and ringing ■ Line and extension numbering ■ Popular Centrex services ■ One-touch access to Centrex services.
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 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.
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).
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.
Name Description Direct Connect Lets the user at a designated extension dial another extension automatically by lifting the handset on a phone. Directed Call Lets a user dial a code to pick up a ringing call that was made to a specific Pickup Centrex extension.
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.

Decisions for Customizing Your System 4 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.
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.
Programmable A telephone button that can be set up to access a feature. button 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.

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

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.
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.
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 set up loudspeaker paging: Connect a loudspeaker paging system to the primary processor module ■ of the equipment controller, as described on page 2-13.
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).
■ ■ ■ ■ 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.
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.
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.
■ 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.

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.
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.
■ Use Doorphone Alert Extensions (#606) to identify up to five extensions that will be signalled by a doorphone when the doorphone button is pressed. Make sure the doorphone extension is not in the Pickup Group (#501), ■ Calling Group (#502), Night Service Group (#504), or Hunt Group (#505).

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).
Speakerphone Performance Tips The speaker and microphone on your MLS-34D, MLS-12D, or MLS-12 telephone is controlled by a sensitive sound-activated switch.
■ Switchhook Ringing Patterns. 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.
Here are some points to remember in using your feature phone with the equipment controller: ■ ■ ■ You will not be able to use System Speed Dial Numbers, although you may be able to program outside phone numbers onto your phone’s feature buttons.
■ ■ Calls ring at both phones. You can handle a call on the standard phone by pressing buttons on the MLS- or MLC-model telephone. For example, you can use the MLS or MLC-model phone to select a specific Centrex line, and conduct the call on the standard phone.
Equipment Feature To Use Manually To Use Programmed on a Button Last Number Redial Redials the last telephone number dialed (maximum 20 digits per phone number). Useful for redialing a busy number. Privacy Prevents people at other extensions from joining a call on your phone.
