INTRODUCTION

Purpose

Voice terminals and adjuncts are voice and data devices that are connected to the system switch in a business communications system. This manual provides concise physical and functional descriptions of the voice terminals/telephones, adjuncts, and data modules that can be used with DEFINITY Generic 1, Generic 2, Generic 3, System 75, and System 85. The book is intended as an aid for both AT&T and customer personnel in selecting appropriate components for these systems and for the training of personnel and management of the system.

This issue replaces all previous issues of this document. The reason for reissue is to add more information on the items included in previous issues of this document and to include the following new items:

8101 Telephone

8403 (8403D01A) Voice Terminal

8410B (8410D02A) Voice Terminal (without a display)

8410D (8410D01A) Voice Terminal with display

8434 (8434D01A) Voice Terminal

CALLMASTER III Voice Terminal

MDC Cordless Telephone

MDW Wireless Telephone

In Issue 3, four new sections were added. The EXPOSED PORT PROTECTION section discusses the different protection required for lightning protection. The AVAILABILITY section lists the availability of the products covered in this manual. The ADJUNCT POWER section discusses the different types of adjunct power supplies available. The ADMINISTRATION section discusses how to administer some of the newer terminals when the software of the version switch being used does not contain the proper administration procedures for the new terminal.

The equipment covered in this manual includes the following specific groups:

Telephones/Voice Terminals

Adjuncts used with the voice terminals to enhance voice operations

Data Modules (adjuncts that support data operations)

PC Platforms (PC/PBX) and Application Software

Attendant consoles, applications processors (APs), printers, and data terminals used with APs are not described in this manual.

Figure 1 shows a typical arrangement of terminals and adjuncts connected to the system switch.

INTRODUCTION

Organization

The remainder of this manual is divided into nine main sections; tabs are provided for convenient access to each section. All equipment descriptions are supported by illustrations.

GENERAL INFORMATION—Gives background data that applies to the entire range of

equipment covered in this manual.

EXPOSED PORT PROTECTION—Contains information on the protection required by

exposed ports. This section also lists some of the AT&T protection devices and gives

parameters that non-AT&T devices must meet.

AVAILABILITY—Lists the ordering status of the equipment covered in this manual.

ADJUNCT POWER—Lists the different terminals and adjuncts that require adjunct

power supplies and the recommended adjunct power supply. Information has also been

added about the MSP-1 power supply.

ADMINISTRATION—When some of the newer terminals are used with some older ver-

sions of the switches, the administration of the switch does not allow for the use of the

new terminals. These new terminals must be administered using the administration pro-

cedures of a similar older terminal. This is called aliasing. This section contains the

aliasing information and the appropriate caveats.

VOICE TERMINALS—Provides detailed coverage of the main groups of voice terminals,

divided into eleven tabbed subsections. This section contains detailed information on

each voice terminal that can be ordered as a component of DEFINITY Generic 1, Gen-

eric 2, or Generic 3, or possibly all three. It also contains brief descriptions of voice ter-

minals that were previously installed in earlier business communications systems. Check

each description to see if these voice terminals are compatible with DEFINITY G1, G2, or

G3, System 75, and System 85.

GENERAL INFORMATION

This section provides general information on all of the equipment described in this manual. Information is provided on voice terminals, adjuncts, data modules, and data terminals. Detailed information on these types of equipment can be found behind the tab for each particular type of equipment.

Voice Terminals

The advanced, multi-appearance voice terminals combine the capabilities of both a telephone and a terminal and have a variety of controlling and monitoring functions. While providing basic telephone service (placing and answering calls), voice terminals can also be used to activate the advanced features of the system.

This part explains higher level topics that apply to voice terminals as a group and contains descriptions of facilities and characteristics that are common to all or most terminals. Table A presents a summary of all voice terminals used with DEFINITY G1, G2, G3, System 75, and System 85.

The complete line of voice terminals are two basic types,

appearance voice terminals.

they access features and the way they receive calls.

The operational differences between these types are in the way

and

multi-

Single-Line Voice Terminals

The term ‘‘single-line’’ means that only one incoming call can be ringing at an idle terminal. Once an incoming call has been answered, however, a single-line voice terminal can handle both the active call and another call on hold or waiting. When a single-line terminal user is busy on a call, an incoming call does not ring but alerts the user via a ‘‘call waiting tone’’ (in the handset or speakerphone) that a call is waiting to be answered. While a single-line terminal is occupied with two calls, any other calls placed to the terminal get a busy tone.

All single-line voice terminals are analog in operation; that is, transmission of all signals between the terminal and its port, at the system digital switch, is in analog form over a tip and ring pair of wires. The port circuit provides analog/digital signal conversion. Power for these terminals is supplied from the switch on the single voice pair. Single-line terminals have many applications but are more limited in their access to system features than multi-appearance terminals.

2-1

GENERAL INFORMATION

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Multi-Appearance Voice Terminals

A multi-appearance voice terminal gives its user much more flexibility in handling calls than a single-line voice terminal. A multi-appearance voice terminal, represented by a unique primary extension number, has multiple call appearances (buttons with lights) where incoming calls to the number can be answered and outgoing calls can be originated. Incoming calls can ring simultaneously at all appearances except for those translated as originate-only. As long as at least one appearance is idle, callers will not receive busy tone. When all call appearances, except call appearances translated as originate-only, are busy, callers will hear busy tone unless the incoming call is a priority call or the Restrict Last Appearance feature is deactivated. The terminal user must decide the order to answer multiple incoming calls.

The two sub-types of multi-appearance voice terminals are digital and hybrid. Digital terminals generate and receive voice and control signals in digital form. Connection between terminals and the system switch is over 2-pair digital links; no conversion is necessary at the digital line port. Hybrid terminals, as the name implies, combine analog and digital. They are connected to the system switch by three pairs of links; on MET-like hybrid sets, one pair is for analog voice, and the other two pairs are for digital control signals, and on ATL-like hybrid sets, one pair is for digital control signals, and the other two pairs are for analog voice. DC power for all multiappearance terminals (except for the 7404D and 7407D01B, which are AC powered) is conducted from the switch over the digital pairs.

Digital multi-appearance voice terminals have several important advantages over hybrids:

Digital voice terminals can support and control data terminals.

The Digital Communications Protocol (DCP) or ISDN-BRI interface between a digital voice terminal and the system switch supports simultaneous voice and data calls over the terminal’s standard mounting cord.

Digital terminals have a wider selection of adjuncts.

Call information displays are available with some digital voice terminals.

GENERAL INFORMATION

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Facilities Common to All Voice Terminals

Every DEFINITY G1, G2, G3, System 75, and System 85 voice terminal has the following equipment:

A pushbutton pad for touch-tone dialing (except for the Model 500, which has a rotary dial)

A handset with a coiled modular cord

A 7-foot modular mounting cord (except for the Model 2554 wall set).

Buttons

All multi-appearance voice terminals and most single-line terminals have buttons for handling calls and activating various functions that enhance basic calling.

Fixed Feature Buttons

Buttons that are factory labeled and require no administration are referred to as fixed feature buttons. The following buttons, in several combinations, are found on most voice terminals. They are dedicated to standard calling functions and are located adjacent to or above the pushbutton dial pad for calling convenience.

Note: Fixed feature buttons that are limited to a small number of terminals are explained in

the detailed descriptions of those terminals.

Recall Button (on older sets)—provides a timed flash that is more accurate than a manual switchhook flash and prevents accidental dropping of calls. The following list of uses for this button is only valid for single-line terminals:

Put an active call on hold and obtain recall dial tone for making another call. Disconnect from a second call and return to a call on hold, when pressed twice. Place an active call on hold and answer a waiting call using Dial Access Code,

then toggle between the two calls (using the Recall button and Dial Access Code).

Place an active call on hold; receive recall dial tone, and dial the Feature Access Code to answer a waiting call. Toggle between the two calls by performing the same action.

Add a party, previously put on hold, to a conference with a third party.

2-4

Drop the party previously added.

Disconnect Button (on older sets)—allows the terminal user, after completing one call, to permanently disconnect from the call and get dial tone for placing a new call without going on- and off-hook. On System 85 and DEFINITY G2, depending on the administration, this button can be used to reconnect to the call on hold on multiple appearance voice terminals.

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Hold Button—is used to temporarily disconnect from one call, without dropping it, so that another call can be answered or originated. The user can return to the call on hold.

Drop Button—is used to permanently disconnect the last party added to a conference call. On System 85 and DEFINITY G2, this button also gives dial tone on the same call appearance if dialing or on a 2-party call.

Note: On some voice terminals, this button is also used to perform a test of the

voice terminal‘s lights, ringer, and display (if the terminal has one).

Conference Button—enables the terminal user to set up a conference call by adding new calls to an existing 2-party connection. The user can add as many as five calls to a conference. (On System 85 and DEFINITY G2 the user can only build a 3-party conference call using this button; 6-party conference calls can be built by the attendant.)

Note: On some voice terminals, this button is also used to select a personalized

ring from 8 available ringing patterns.

GENERAL INFORMATION

Transfer Button—enables the terminal user to shift an active call to another voice termi nal.

Select Ring Button (on older sets)—enables the terminal user to select a personalized ringing pattern.

Speaker Button—turns on either a listen-only speaker or a 2-way speakerphone which allows the user to speak and listen to the far-end party.

Note: On some voice terminals, this button also allows the user to initiate an

acoustic test of the surrounding environment (the Reset Speakerphone feature) through a series of tones. When the tones stop, the speakerphone has finished adjusting itself for optimal performance.

Mute Button—turns off the microphone of the built-in speakerphone or the handset so the other person on the call cannot hear you.

Administrable Buttons

Buttons that are not fixed feature buttons are administered (or assigned) by the System Manager or the terminal user for many functions. Buttons that may be administered include call appearance/feature buttons and feature-only buttons.

Every multi-appearance voice terminal has a minimum of three buttons while others have as many as 34 buttons that can be administered as call appearances, that is, positions for answering incoming calls and originating outgoing calls (see Figure 1). In DEFINITY G1 and System 75, software defaults the first three of these buttons for appearances of the terminal’s primary (or home) extension number; the System Manager has the option of administering Button #3 differently. In DEFINITY G2 and System 85, no buttons are defaulted for the primary extension number; the System Manager

must

administer all the required positions. Buttons not used for the primary extension number can be assigned as appearances of other extensions or for activating optional features.

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

FIGURE 2-1. Call Appearance/Feature Buttons

Associated with each call appearance/feature button is a pair of lights that provide information on the availability and status of the appearance. These lights are described in the next part of this manual (titled ‘‘Lights’’).

Any button that can be administered and is not used for a call appearance can be assigned to an optional feature. Included in this category are buttons with two lights (call appearance/feature buttons) and buttons with one or no lights, intended specifically for features. Some features require light feedback to inform the terminal user when the feature is active; others are simple, one-time operations for which light feedback would be meaningless. Good feature administration matches features to appropriate buttons whenever possible.

2-6

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

GENERAL INFORMATION

Lights

Indicator lights provide silent visual reminders to the voice terminal user regarding lines, features, and messages taken at other locations. The lights on DEFINITY G1, G2, G3, and System 75 and 85 voice terminals are light-emitting diodes (LEDs) or neon lights.

On all multi-appearance voice terminals, each call appearance/feature button has two indicator lights: a red light and a green status light. When a call appearance/feature button is used for a feature, only the status light is operational; the red light remains off at all times. Feature-only buttons have either a single green status light or no light at all. The various arrangements of red and green lights are shown in Figure 2.

GENERAL INFORMATION

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Red Light

The red light normally has two states: lighted steadily or dark (off).* One red light is always on at a multi-appearance voice terminal when the handset is on hook. It identifies the call appearance the user will be automatically connected to if the handset is lifted. When the handset is lifted, the red light identifies the call appearance that is active.

The red light is off when the handset is lifted but not connected to a call appearance; for example, when one call has been put on hold but another call appearance button has not been pressed. When certain features such as Preselection, Idle Line Originating preference, or No Line Originating Preference are administered, the red light is also off while on hook.

Green Status Light

The green status light can indicate any one of the following six conditions:

Off—the call appearance is idle or the assigned feature is not activated.

Lighted steadily—the call appearance is busy or the assigned feature is active.

Flashing (slow on-off for equal periods, one cycle per second)—an unanswered incoming call on that call appearance.

Fluttering (fast on-off for equal periods, 10 cycles per second)—a call placed on hold on that call appearance by the voice terminal user.

Broken Fluttering (fast on-off modulated at the slow rate)—feature denial to the calling voice terminal or an unknown or invalid action.

Winking (long on-short off at about three cycles per second)—a call placed on hold from another voice terminal or an action pending.

Message Light

The Message light, when on, indicates that a message is waiting for the voice terminal’s user (for example, Leave Word Calling or voice mail messages). When the user retrieves the message, the light is automatically turned off.

aaaaaaaaaaaaaaaaaaa

* On the ISDN-BRI 7505, 7506, and 7507 sets, the red light flashes when the set is using phantom power.

2-8

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

GENERAL INFORMATION

Tones

The tones that a voice terminal user hears can be divided into two categories:

Ringing Tones—those that are generated in the base of the voice terminal and can be heard in the surrounding area; they indicate incoming calls.

Handset Tones—those that are transmitted through the handset and heard only by the user or through the speakerphone when it is turned on.

External Ringing Tones

Ringing tones are the only tones heard

outside the voice terminal

when it is receiving a call. This signal cycles in 1-, 2-, or 3-ring patterns. On System 75 and DEFINITY G1 and G3, only one cycle of ringing is heard if the multi-appearance voice terminal is busy with another call. On System 85 and DEFINITY G2, the cycling repeats (except on the ISDN 7500-series sets).

One ring—a call from another voice terminal in the system

Two rings—a call from the attendant or outside caller

Three rings—priority calls, for example, Automatic Callback, Priority Calling, or Ringback from a queued call

One short unmodulated tone—an intercom call

Ring-Ping (half ring)—a call redirected away from the voice terminal because Send All Calls or Call Forwarding is active; also called coverage tone.

On System 85 and DEFINITY G2, any of these external tones, plus a repeated unmodulated tone, may be administered to indicate an intercom call.

Handset Tones

The following tones are heard through the handset:

Answer Tone—a high-pitched continuous tone indicating that a data endpoint has answered.

Busy Tone—a low-pitched tone repeated 60 times a minute; indicates that the number dialed is in use.

Call Waiting Tone (Single-Line Voice Terminals)—one, two, or three beeps (short bursts of high-pitched tone), not repeated; indicates to the user at a busy single-line terminal that an incoming call is waiting to be answered. The number of beeps indicates the source of the waiting call:

One beep—a call from another voice terminal in the system Two fast beeps—a call from the attendant or an outside caller Three fast beeps—a priority call

2-9

GENERAL INFORMATION

Confirmation Tone—(three short bursts of tone) indicates that a feature activation or cancellation has been accepted, or that an outgoing call from a single-line voice terminal has been placed in a ringback queue.

Coverage Tone—(one long burst of tone) indicates to the calling party that a call to an extension number will be answered at another extension number by a covering user.

Dial Tone—(a continuous steady tone) indicates that dialing or feature activation can begin.

Intercept Tone—(an alternating high and low tone) indicates either a dialing error or a denial of the service requested.

Recall Dial Tone—(three short bursts of dial tone followed by steady dial tone) indicates that the feature requested has been accepted and dialing can start.

Recorded Telephone Dictation Ready Tone—(a high-pitched continuous tone) indicates that a dictation machine has been connected to the voice terminal.

Reorder Tone—(a fast-busy tone repeated 120 times a minute) indicates that all outgoing trunks are busy or feature resource is not available. Try again.

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Ringback Tone—(a low-pitched tone repeated 15 times a minute) indicates to the calling party that the number dialed has been reached successfully and is ringing.

Ringback Tone, Call Waiting—(a ringback tone with a short lower-pitched signal at the end) indicates to the calling party that the extension called is busy, but that the called party has been given the call waiting signal.

Time-Out Tone—[an alternating high and low tone (same as intercept tone)] indicates a failure to dial within a preset interval (usually 10 seconds) after lifting the handset or after dialing the previous digit.

Warning Tone (Bridging)—(a low-pitched tone heard by all parties in a Busy Verification attempt that bridges on to an active call) initially applied in a 2-second (System 75 and G1) or 4-second (System 85 and G2) burst, then in half-second bursts every 15 seconds.

Desk/Wall Mounting Arrangements

All the voice terminals covered in this manual, except the Model 2554, are intended for freestanding desktop use. However, wall-mounting is feasible for many terminals and appropriate kits are available. The detailed description of each voice terminal contains wall-mounting information and limitations.

2-10

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

GENERAL INFORMATION

Adjuncts

Adjuncts are optional devices that extend the existing capabilities of voice terminals or provide new services. Some adjuncts are physically attached to their voice terminals, and others are free-standing, connected by way of mounting cords. The adjuncts have styling and colors that are compatible with the associated voice terminals.

Table B provides a cross-reference between adjuncts and the voice terminals with which they are used. The following limitations apply to the use of multiple adjuncts:

A speakerphone and a headset adapter cannot be connected to the same voice terminal simultaneously because they plug into the same jack on the terminal.

A C401A Call Coverage Module and a D401A Digital Display Module cannot be mounted on the same 7405D or 7434D Voice Terminal simultaneously because they attach to the same part of the terminal.

None of the adjuncts have facilities for wall mounting, and wall-mounting kits are not available. However, the modules (call coverage, function key, and digital display) are attached to their voice terminals, which can then be mounted on a wall. Free-standing adjuncts (speakerphones and headset adapters) associated with wall-mounted terminals can be placed on a nearby shelf or table.

Data modules provide an interface between the system’s digital switch and Data Terminal Equipment (DTE) or Data Communications Equipment (DCE). DTE is defined as a data source or a data link or a combination of both; typical examples are data terminals and host computers. DCE is equipment that provides the functions for establishing, maintaining, and terminating a data call; a modem is an example of DCE.

An interface device between the switch and DTE or DCE is necessary because the set of data transmission rules and formats—the data protocol—at the switch is different from the protocol at the DTE or DCE. The digital ports of the switch present a Digital Communications Protocol (DCP) or ISDN-BRI interface to all devices connected to them. DCP supports simultaneous voice and data communications by multiplexing the two sets of signals into one digital stream. Digital voice terminals and some data terminals can be connected directly to the switch. But, if a data endpoint has a different protocol (EIA RS-232C or RS-232D is the most common) than the switch, a data module must be inserted to provide compatibility. The data module provides the two-way data signal conversion and processing required between different protocols. Figure 3 shows a simplified diagram of the components of a typical data link.

FIGURE 2-3. Data Link Components

The connection between a data module and a data endpoint must always have a DCE or DTE interface. If the endpoint is a DCE, the data module must present a DTE interface to it. If the endpoint is a DTE, then the data module must present a DCE interface. In general, modules are classified as DCE- or DTE-type according to the kind of data endpoint to which they are connected.

Data modules are available to match a wide variety of data needs:

Asynchronous operation at data rates from 0.3-19.2 kbps and even, odd, mark/space, zero/one or no parity options

Synchronous operation at data rates of 0.3, 1.2, 2.4, 4.8, 9.6, 19.2, 56, and 64 kbps

2-14

Half- or full-duplex operation and internal or external timing options at the appropriate data rates

GENERAL INFORMATION

The following data equipment is available with DEFINITY G1, G2, G3, System 75, and System 85:

7400A Data Module—In DTE mode, works with asynchronous DCE in the modem pool at data rates of 0.3-19.2 kbps, full-duplex. Supports both Hayes-compatible and D-lead modems. In DCE mode, the 7400A has Hayes, Keyboard Dial or Answer-Only interface. Also works with asynchronous DTE where rack mounting is needed. Takes the place of MTDM or MPDM in asynchronous applications.

7400B and 7400B Plus Data Modules—Works with asynchronous DTE at data rates of

0.3-19.2 kbps, full-duplex. Can be used with most 7400-series DCP voice terminals for simultaneous voice/data or standalone. Emulates a Hayes-compatible modem, therefore, can be used with standard PC communications packages. Takes the place of previous DCP asynchronous data stands.

Modular Processor Data Module (MPDM)—Works with synchronous DTE at data rates of 0.3-64 kbps. Also works at full- or half-duplex with internal or external timing at the appropriate data rates. Supports V.35, RS-232, and RS-449 interfaces and RS-366 Automatic Calling Unit interface at the previously mentioned rates. Video codes are an example of 56 or 64 kbps endpoints where calls are set up via the RS-366 interface. The MPDM also supports asynchronous applications, but the 7400B Plus supersedes it for applications requiring Hayes emulation and the 7400A supersedes it for remaining asynchronous applications.

Modular Trunk Data Module (MTDM)—Works with a synchronous DCE in modem pool applications at data rates of 0.3-19.2 kbps. Also works at full- or half-duplex with internal or external timing at the appropriate synchronous data rates. The 7400A supersedes it for asynchronous applications.

7500B Data Module—Works with asynchronous or synchronous DCE or DTE on BRI switch interface (DEFINITY G2 or 5ESS switch only). Supports RS-232 and V.35 interfaces and RS-366 Automatic Calling Unit interface (for the RS-232 interface only).

ISDN Asynchronous Data Module (ADM)—Works with asynchronous DTE as a data stand for 7500-series BRI phones (DEFINITY G2 and 5ESS switch only). Supports Hayes command set for compatibility with PC communications packages.

Definity High Speed Link—Works with synchronous V.35 DTE at data rates of 56 kbps half or full duplex or 64 Kbps full duplex. Supports Permanent (private line type) calls and switched calls. Switched calls can be set up using either the RS-366 or RS-232 (Hayes ATD command) interface; via DTR or Hotline dialing; or manually using the front panel call control feature. Replaces the ACCUNET MPDM for video, LAN, CC/FEP and other high speed applications.

Asynchronous Data Unit (ADU)—Works with asynchronous DTE at data rates of 0.3-

19.2 kbps. Used where the user has an analog voice phone and needs basic capabilities for asynchronous terminals as opposed to PCs. Connects to SN 238 (System 85 and DEFINITY G2 traditional modules) or TN726 (System 75 and DEFINITY G1 and G2 universal modules).

Multiple Asynchronous Data Unit (MADU)—Works with asynchronous DTE at data rates of 0.3-19.2 kbps in host applications. The MADU is rack-mounted and supports busy-out. It connects to the same switch ports as the ADU.

GENERAL INFORMATION

Data Terminals

A data terminal is a workstation at which data is entered and retrieved; it communicates through lines, trunks, switches, and data modules with data endpoints such as computers and other data terminals. Some data terminals contain built-in voice capabilities similar to digital voice terminals. For detailed information on buttons, lights, and tones, refer to the general information about voice terminals at beginning of this section.

The following data terminals are available with System 75, System 85, and DEFINITY G1 and G2:

AT&T Personal Terminal 510A (no longer manufactured)(DA)

AT&T Personal Terminal 510D (no longer manufactured)(DA)

Model 513 Business Communications Terminal (BCT) (no longer manufactured)(DA)

Model 515 BCT (no longer manufactured)(DA)

Model 610 BCT

Model 615 MT

The 513 BCT, 610 BCT, and 615 MT, in addition to being optional units of peripheral equipment, are used in DEFINITY G1 and System 75 as System Access Terminals (SATs). The SAT is dedicated to system administration and maintenance and is located in or nearby the equipment room with the DEFINITY G1 or System 75. This manual does not cover the 513, 610, or 615 as an SAT but only as peripheral data terminals used for sending and receiving data calls.

EXPOSED PORT PROTECTION

Requirements

All port packs and terminals require unique protection and grounding arrangements as defined in the checklists ( 555-200-120 and 555-103-120). These arrangements provide an adequate barrier to the potentially damaging voltages and currents inherent in lightning and power surges present in exposed applications. Moreover, the National Electrical Code requires that an approved protector be provided on all exposed circuits.

Exposed Ports And Terminals Defined

Ports and terminals that utilize facilities that are subject to disturbances from lightning, ground potential rises (GPR), or possible contact or induction from electrical power sources or circuits in excess of 300 volts (RMS) to ground are classified as exposed. Any ports or terminals served by such exposed facilities are classified as exposed and require protection at both the port and terminal ends. The checklists contain flowcharts that are beneficial in determining exposure status and tables to determine the type of protector required.

Out-of-Building Campus Stations

An out-of-building campus station is a telephone or voice terminal that is not physically located in the same building as the equipment room, but is located on the same property. Both analog telephones and digital voice terminals can be used as out-of-building stations

Carbon block, or equivalent, protection is required at both building entrances for analog out-ofbuilding stations. Sneak current protection is also required. Protection can be provided by a 4-type protector or a 3-type protector plus a separate sneak current protector. The 4-type protector is equipped with a heat coil for sneak current protection. The 4-type primary protector is the preferred device.

Protection is required at both entrances for digital out-of-building voice terminals. There are two different types of protectors that can be used to protect digital voice terminals and digital line circuit packs in an out-of-building environment: the 4C3S-75 Enhanced Protector and the ITW Linx Enhanced Protector.

Note: The 4C3S-75 Enhanced Protector may only be used on Vintage 14 or newer TN754

Circuit Packs. The 4C3S-75 can be used on all vintages of the TN754B Circuit Pack. The ITW Linx Enhanced Protector may be used on all Vintages of the TN754 and TN754B Circuit Packs.

The 4C3S-75 Enhanced Protector is equipped with a heat coil for sneak current protection and the ITW Linx Enhanced Protector is equipped with replaceable fuses for sneak current protection.

The maximum range for out-of-building voice terminals is 3,400 feet when using 24 AWG wire

and 2,200 feet when using 26 AWG wire. The range can be extended to 5,000 feet (24 AWG) or 4,000 feet (24 AWG) with the use of a Data Link Protector (DLP). The DLP is an isolating transformer used to remove phantom power on the switch side and reintroduce it on the terminal side. When a DLP is used, the voice terminal must be locally powered by an external power supply or through the AC power cord provided with some of the 7400 series voice terminals. The DLP is installed on the equipment side of the protection in both buildings. In high lightning areas, the DLP may also be installed to provide the maximum degree of protection and reliability.

Table A shows the recommended protectors for the DEFINITY G1, G2, G3, System 75, and System 85. Table B shows the in-range, out-of-building (IROB) protection for DEFINITY line circuits and terminals.

Caution: The following circuit pack and terminal arrangements are not allowed to be

installed in an exposed environment:

1. 7300 Series connected to the TN762B or ANN17 Circuit Pack

2. MET terminals connected to the TN735 Circuit Pack

3. Analog terminals connected to the TN746 Circuit Pack

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

2-30

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

ADJUNCT POWER

Power for several of the adjuncts must be provided locally at the voice terminal or from a satellite closet through the terminal wiring. The following power supplies are currently recommended:

The MSP-1 (WP92464L1) Power Supply—replaces the KS-22911 L1/2, 329A, and 353A DC power supplies and the 2012D AC transformer. The MSP-1 can be used to supply local power to ISDN-T 65xx, 75xx, and 85xx series voice terminals connected to an AT&T DEFINITY Communications System and to the DCP 7444 and 8434 voice terminals which need auxiliary power for their vacuum fluorescent displays. The MSP-1 can also supply auxiliary power to adjunct equipment such as the S201A and CS201A speakerphones or a 500A Headset Adapter attached to any currently manufactured analog, DCP, or ISDN-T voice terminal equipped with an Adjunct jack. For more information on the MSP-1 power supply, see the short section with connection diagrams later in this section.

The ISDN 1145B1 Bulk Power Unit, 1146B Power Distribution Unit, and the 2.5/5.0 A.H. back-up batteries provide an uninterruptible power source for ISDN telephones and terminals, NT1s, terminal adjuncts, and other customer premises equipment. During AC power interruptions, batteries are automatically switched on to provide continuous power to the load.

The distribution of power to the terminal equipment is provided by the 1146B distribution unit. The 1146B provides 32 standard 110 connections to the load with overcurrent protection and alarm lights. The 1145B1/1146B power arrangement is compact (measuring only 6.5 inches deep), lightweight, plastic enclosed, and designed for easy wall- or rackmounting.

During normal operation, the power supply/charger provides DC power to the load via the distribution unit while maintaining the battery in a fully charged condition. The power system continuously monitors systems conditions with the status displayed on the front panel of the power supply and distribution unit.

The following power supplies and transformers are NO LONGER recommended. They have been replaced by the MSP-1 power supply and the 1145B1 bulk power unit described above.

2012D AC transformer— can be used locally or in a satellite closet to power a single 18 volt headset adapter or speakerphone.

KS-22911, L2 DC power supply—can be used locally or in a satellite closet to power a headset adapter or speakerphone plus one additional adjunct. This unit has a 48 volt power output of 10 watts.

KS-21239, L4, L5 AC transformer—can be used locally or in a satellite closet to power a single 24 volt speakerphone-dialer.

PS3081096 AC transformer—can be used locally or in a satellite closet to power the 24 V S201A or S203A speakerphones.

329A DC power supply—can be used locally or in a satellite closet and is capable of supplying power to any number of adjuncts that may be added to a digital voice terminal. This unit has a power output of 25 watts.

2-31

ADJUNCT POWER

346A modular bulk DC power supply—can be used in a satellite closet only and is capable of supplying power to any number of adjuncts that may be added to a digital voice terminal. This unit provides switch-selectable options for four outputs at 10 watts or two outputs at 20 watts.

85B1-49 power unit—can be used locally or in a satellite closet to power the 4A speakerphone.

95B1 power unit—can be used locally or in a satellite closet to power a 2870A1 automatic dialer.

353 DC Power Supply—can be used locally only. It is designed to supply power to ISDN-BRI stations and their adjuncts. It has a power output of 12 watts.

945 Bulk DC Power Supply—can be used in a satellite closet only. It is designed to power ISDN-BRI stations and their adjuncts. It can optionally be equipped with a battery to provide terminal operation for a limited time in case of an AC power failure. Up to 26 ISDN-BRI terminals can be supported by the 945 power supply.

Information on the Older Power Supplies

The following diagram shows the connections with the older power supplies.

Note: The MSP-1 replaces the KS-22911 L1/2, 329A, and 353A DC power supplies and

the 2012D AC transformer.

FIGURE 2-4. Local and Satellite Power Sources for Voice Terminals Adjuncts

2-33

ADJUNCT POWER

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

One of these power supplies must be used for each voice terminal equipped with one or more adjuncts. Each of these power supplies (except the 95B1) has a maximum cable distance of 250 feet (76 m) between the power supply and the adjunct(s). The maximum cable distance for the 95B1 is 150 feet (45m). Voice terminal adjuncts and modules are not operational during interruptions of commercial AC power unless their power supplies are also powered through standby power of other essential AC power service.

The 329A and 346A power supplies clustered in a satellite closet are normally mounted on AC power strips. Power to these strips is provided from a dedicated 120 volt AC, 60-Hz, 20-ampere circuit breaker and feeder either directly or through a 543A telephone power unit. The 543A unit provides an inductive filter to limit inrush current on the feeder. It comes equipped with an AC power cord which plugs into the dedicated feeder and provides four receptacles for AC power strips.

The 945 bulk power system is usually rack mounted and is intended to be located in an equipment room or satellite closet. It is optionally made up of the following components:

945-1 bulk power supply unit

945-2 battery reserve unit

945-3 system enclosure, equipped with one or two 945-1 and/or a 945-2

945-4 single enclosure for 945-1 unit

Several power supplies and connection schemes are available for providing auxiliary adjunct power when it is required. Regardless of its source, auxiliary power is introduced into a pair of spare leads in the individual voice terminal’s line, at some wiring interface. The auxiliary power is fed into the terminal on the mounting line cord. From the terminal, power is distributed to the adjunct(s). An auxiliary power source is usually mounted in a satellite closet or adjacent to the voice terminal’s wall jack.

ADJUNCT POWER

The MSP-1 Power Supply

The MSP-1 (WP92464L1) Power Supply can be used to supply local power to ISDN-T 65xx, 75xx, and 85xx series voice terminals connected to an AT&T DEFINITY Communications System and to the DCP 7444 and 8434 voice terminals which need auxiliary power for their vacuum fluorescent displays. The MSP-1 can also supply auxiliary power to adjunct equipment such as the S201A and CS201A speakerphones or a 500A Headset Adapter attached to any currently manufactured analog, DCP, or ISDN-T voice terminal equipped with an Adjunct jack.

CAUTION: The MSP-1 Power Supply can be used

only

with telecommunications equipment,

indoors, in a controlled environment.

NOTES:

One power supply will support one telephone with or without an adjunct. The maximum loop range between the telephone and the power supply is

250 feet. This power supply replaces the KS-22911-L1/2, 329A, and

353A DC Power Supplies and the 2012D AC Transformer.

The MSP-1 power supply has a single output of -48 volt DC, 0.4 amperes, and can operate from either a 120 VAC 60 Hz power source (105 to 129 VAC) or a 220/230/240 50 Hz power source (198 to 264 VAC). Input voltage selection is automatic; that is, the power supply adjusts itself for the type of input voltage. The output capacity is 19.2 watts.

ADMINISTRATION

This section contains some of the information necessary to administer the different voice terminals on DEFINITY G1, G2, G3, System 75, or System 85. It also provides the caveats required when administering some of the newer voice terminals to the older systems. Other administration information for DEFINITY G1 and G3 or System 75 is provided in the DEFINITY G1 and G3 and System 75 Implementation and Administration manuals. The administration information for DEFINITY G2 and System 85 is provided in the System 85 and DEFINITY G2 Translation Service Manual.

Important: The sections of this manual which describe the newer voice terminals provide

detailed information on administering that voice terminal. In most cases, diagrams of the button numbering schemes are also provided. For example, if you want to administer a 7407 Plus voice terminal, see the section on the 7407 Voice Terminals under the tab labeled 7400 Series..

Aliasing

When some of the newer voice terminals are used with some older versions of the switches, the administration procedures of the switch does not allow for the use of the new terminals. These new terminals must be administered using the administration procedures of a similar older terminal. This is called ‘‘aliasing’’ a set.

When aliasing is used to administer a voice terminal, often the ‘‘old’’ screen used in administering buttons and features displays more buttons than can actually be assigned to the new terminal. These differences are provided in this section also.

The following tables list the aliases used in administering the terminals. If the terminal you are administering is not listed in the tables, then it is administered as itself in all versions of the switch.

* CAVEATS for administration of the 8434 voice terminal:

The 8434 may be aliased as a 7405+D+F to support all system features. However, in this case, while all the call appearance/feature buttons AND the softkey features will be functional, there can be a maximum of only 10 call appearances. On the 7405, the Display Module is a 1-line display, and thus the 1-line display option should be selected.

On some systems, the 8434 can be aliased as a 7434+D or a 7444 to support coverage. In this case, there can be up to 34 call appearances (including bridged call appearances), but the 15 softkey features will NOT be functional because the Feature Key Module is not allowed with the 7434 or 7444. On the 7434, the Display Module is a 1-line display, and thus the 1-line display option should be selected. If the set is administered as a 7444, it can be optioned for a 2-line display.

An 8434 connected to a DEFINITY G3V2 can be administered as a 7444; an 8434 connected to a DEFINITY G3V3 (or later) can be administered as itself.

**An 8510T voice terminal connected to a DEFINITY G1 or G3 can be administered as itself, but an 8510 data

PC/ISDN Platform (DEFINITY G2). To administer the PC/ISDN Platform, the Generalized Terminal Administration (GTA) capability of DEFINITY G2 must be used. Below is an overview of how to administer it. See the

PC/ISDN Installation and Reference Manual

for detailed instruc-

tions. PC/ISDN Administration on DEFINITY G2. Ordinary BRI terminals used with DEFINITY G2

require initialization. They also support Maintenance Information Messages (MIMs). Because PC/ISDN supports neither MIMs nor terminal initialization, the system administrator must have created a have an associated display, the display type must be changed to 6 for

terminal type

for each type of terminal being used with PC/ISDN. If the terminal is to

personal computer

. Each terminal thus created is simply a copy of the terminal type for the terminal at hand with the ISDN-MIM feature set to

None

and the display type set to 6. For example, if the terminal to be administered is an AT&T model 7507, the system administrator might copy the 7507 terminal (type 57) to a new terminal type (e.g., type 157) and modify it to exclude support of the ISDNMIM feature.
