CHAPTER 1. INTRODUCTION

Overview

This manual provides the procedures and associated forms for collecting system and voice terminal features. This information is used with AT&T System 75—Administration, 555-200500, to initialize the AT&T System 75 and System 75 XE using the System Access Terminal.

In the planning process, system requirements were identified by the AT&T Account Team and the customer. Those requirements were converted into orderable system hardware when

the Account Team configured the system.

This manual is solely concerned with AT&T System 75 implementation; that is, the

completion of paper records and forms that are used to initialize and administer the System 75 Release 1 Version 3 or the System 75 XE.

This manual explains the forms required to implement the various system and voice terminal features. Instructions on how to complete each paper record and form are also provided.

AT&T System 75—Administration, 555-200-500, explains how to use the paper records to

initialize and administer the system. The chart in Figure 1-1 depicts work activities and relative time frames. This manual provides the forms and instructions required to implement a System 75 Release

1 Version 3 (RlV3) or a System 75 XE. All forms and features described in this manual apply to a Release 1 Version 3 System 75 and a System 75 XE unless otherwise noted as V3 or

System 75 XE. This manual is being reissued to include the following information.

• Add V3 enhancements Ž Add information for the Hospitality Parameter Reduction feature

• Add 7309H voice terminal

• Provide detailed information on how to implement AUDIX in a DCS or non-DCS environment.

To complete this manual, you must:

• Have hardware and feature knowledge (consult AT&T System 75—System Description, 555-200-200, and AT&T System 75—Feature Description, 555-200-201 )

• Know what system and terminal hardware has been ordered [refer to the Delivery Operations Support System (DOSS) order]

CHAPTER 2. ARS AND TRUNKS—INSTRUCTIONS

AND FORMS

Overview

This chapter contains the forms and instructions required to assign Automatic Route Selection (ARS) and System 75 trunks.

The first part of this chapter covers ARS. The second part covers the System 75 trunks. The blank forms for ARS and trunks are in Chapter 7. Reproduce a blank form for the ARS and trunk forms being used.

Automatic Route Selection

ARS routes calls over the public network based on the preferred (normally the least

expensive) route available at the time the call is placed. ARS provides a choice of up to six routes from any given public network call. The following types of trunk groups can be accessed by ARS:

• Local central office—Used for local calls and to provide access to long-distance carrier. Access to the long-distance carrier can be provided automatically by the

central office or by a carrier access code.

• Foreign exchange—Used to emulate local calling in an area served by the local central office.

• Wide Area Telecommunications Service (WATS)—Used to provide calling to

predefine geographic areas at a rate based on expected usage.

• Tie trunks—Used to provide access to an Electronic Tandem Network (ETN), or to

an Enhanced Private Switched Communications Service (EPSCS) or Common Control Switching Arrangement (CCSA) office.

The following forms are used to assign ARS features:

Ž ARS Foreign Numbering Plan Area (FNPA)

• ARS Home Numbering Plan Area (HNPA)

Ž ARS Remote Home Numbering Plan Area (RHNPA)

• ARS Toll Table

• Code Restriction FNPA

ARS—Foreign Numbering Plan Area (FNPA)

Automatic Route Selection—Foreign Numbering Plan Area (FNPA)

Purpose

This form is used to assign the routing pattern associated with each FNPA. The ARS FNPA table points to the appropriate Routing Pattern for each nonlocal NPA or points to a 6-digit translator so the call will be routed on both the NPA and the office code.

Although they are not FNPAs, the codes 00x, 01x, 10x, and 11x (where x is a number 0 through 9) can be assigned for routing calls beginning with these digits.

The system recognizes certain types of dialing patterns on outgoing calls and routes these

calls via special entries in the FNPA or HNPA table. Table 2-A lists the special dialing patterns along with the associated FNPA or HNPA table entry through which that type of call is routed.

CHAPTER 2. ARS AND TRUNKS—INSTRUCTIONS AND FORMS

Typical assignments for the FNPA Table are as follows:

—

"H"—pattern/table assignment for the HNPA

—

"R"(1-32)—office code translation of a given NPA and Pattern Numbers

Patterns should be created to accommodate individual customer needs. Careful application of this table permits Automatic Route Selection for all types of calling including IDDD (International Direct Distance Dialing) and carriers other than AT&T.

Instructions

Make assignments as required for the following fields:

• Partitioned Group Number—Enter a group number from 1 through 4. Ž Pattern Choice Assignments—

For the x00 through x19 fields in each FNPA block (000-019 through 900-919), enter a number from 1 through 254 for the desired pattern number or a number from 1 through 32 preceded by “r” (for example, r1, r15, r32) for the desired RHNPA Table Number. Enter “h” or “H” as the pattern number for the Iocal(home) NPA to indicate that this NPA is the HNPA rather than an FNPA.

ARS—Home Numbering Plan Area (HNPA)

Automatic Route Selection—Home Numbering Plan Area (HNPA)

Purpose

This form is used to assign the routing pattern associated with each of the 800 office codes in the local area code. The ARS HNPA Table points to the appropriate routing pattern for each office code within the home NPA.

The default value for all 800 office codes is pattern 1. Normally, pattern 1 should be used as the HNPA toll pattern because in most NPAs there are more toll offices than local office codes. This will minimize the number of changes required to complete the form.

Instructions

Make assignments, as required, for the following fields:

• OFFICE CODE—Enter a hundreds block; that is, 200-299 through 900-999.

● Partitioned Group Number—Enter a group number from 1 through 4.

• Pattern Choice Assignments—

Enter a pattern number from 1 through 254.

ARS—Remote Home Numbering Plan Area (RHNPA)

Automatic Route Selection—Remote Home Numbering Plan Area (RHNPA)

Purpose

This form is used to assign office codes and the associated routing pattern number for 32

selected RHNPAs. One form is required for each block of 100 central office codes. RHNPAs are referenced from the FNPA Table and are commonly referred to as “6-digit

translators.” The RHNPA Table provides a choice of up to 12 routing patterns for each block of 100

central office codes, whereas the HNPA Table provides a choice of 254 routing patterns for each office code.

Instructions Make assignments as required for the following fields:

• ARS RHNPA TABLE—Enter the applicable table number from 1 through 32. Up to eight forms may be required for each table, one for each hundreds block, 2 through

• OFFICE CODE—Enter the desired hundreds block; that is, 200-299 through 900-999. A separate form is required for each hundreds block.

• Pattern Choices—Enter a pattern number from 1 through 254 representing the Routing Patterns that can be accessed by the RHNPAs identified on this screen form only. Each screen form on each RHNPA table may have 12 different Pattern Choices. Patterns listed on one screen form do not automatically default to the other forms of the same table. If one pattern will be used most often (that is, accessed by the greatest number of office codes in this block), assign that pattern as choice 1. Otherwise, the correlation between Pattern Choice numbers and Patterns is completely arbitrary.

• Office Code—Pattern Choice Assignments (from 1-12 above)—Enter a Pattern Choice number from the list above in the field associated with each Office Code. The Office Code fields represent the last two digits of the codes within the hundreds block. The Pattern Choice Assignment points to the Pattern Choice, above, that contains the Routing Pattern to be used.

Dial Plan

Purpose

The Dial Plan is the system’s guide to digit translation.

Instructions

Make assignments as required for the following fields:

Ž Area Code—Enter the Home Numbering Plan Area of the PBX,

Ž ARS Prefix 1 Required—Enter “y” if the user is required to dial 1 to indicate a 10-

digit toll call. This is required when the PBX is located within an area code that contains a Central Office Code resembling an area code. These are the following:

— 201 in New Jersey — 212 in New York

Dial Plan

— 213 in Los Angeles — 312 in Chicago — 706 in Northwest Mexico — 905 in Mexico City

The following paragraphs show how dialed numbers are interpreted by the system if

"y" is assigned to the ARS Prefix 1 Required, field. The number 9 represents the

ARS Access Code.

— 9+1+(212)-201-1234 infers a 10-digit toll call.

— 9+(212)-201-1234 infers that 212 is a Central Office Code. The system

accepts only the first seven digits following the ARS Access Code. The

number 212-2011 is sent to the Central Office. — 9+201-1234 infers a 7-digit call within the HNPA. — 9+1+201-1234 infers the first seven digits of a 10-digit toil call and waits for

the remaining three digits. The number being outpulsed is (201)-123-4xxx.

If the number being dialed is a toll call within the HNPA and the Central Office

Code resembles an area code as in the example above, then the HNPA must

also be included in the number dialed (refer to the first example). — 9+922-1234 or 9+1+922-1234 infers a 7-digit call (or toll call) within the

HNPA. This example differs from the preceding example in that the Central

office Code (922) does not resemble an area code.

2-15

CHAPTER 2. ARS AND TRUNKS—INSTRUCTIONS AND FORMS

• Uniform Dialing Plan—

feature can only be assigned if UDP or DCS is provided. If this feature is activated, the Dial Plan becomes 6 pages. Enter “y” if DCS is used.

• Plan Length—Enter the number of digits in the UDP (valid entries are “4” or “5”).

These numbers are used to signify the user of a 4- or 5-digit Dial Plan.

• FIRST DIGIT TABLE—Assign “fac” as the Identification for the Digit 9.

Trunk Characteristics

A trunk is named for its transmission characteristics and can be analog or digital depending on the type of signals it carries.

the transmission of supervision, address, alerting, or other switching information between

switches.

One transmission characteristic is signaling. Signaling is

A trunk is further classified as one of the following:

• 1-way incoming trunk—A local trunk that can be selected (seized) by the far-end connected switch.

General

• 1-way outgoing trunk— end switch.

• 2-way trunk

—A trunk that can be seized at either end of the connected switches.

A trunk that can be seized by the local switch to call the far-

Transmission of Supervision

One of four types of supervision signaling is used in trunks. These four types are:

• E & M (Ear & Mouth) supervision— network trunks in which dc voltage levels are sent over E and M leads. The E and M leads are separate from the transmission path (T & R leads). E & M signals indicate on-/off-hook states of each end of the connection path. E & M signaling is further divided into types (Type I through V). DIMENSION® PBX systems use only Type I and System 75 and System 85 can use Type I or V. Type I is signaling from the trunk interface to the far-end over the M lead using nominal -48 volts for off-hook and local ground for on-hook. Signaling from the far-end is over the E lead using far-end ground for off-hook and open for on-hook. Type V is signaling in both directions by means of open for on-hook and ground for off-hook.

• GS (Ground Start) supervision— network trunks in which ground is applied on the Tip (T) lead by the CO, and on the Ring (R) lead by the PBX. For example, the calling PBX on a call to a central office using an outgoing trunk interface seizes the outgoing trunk by placing a ground on the trunk interface R lead. The CO recognizes the trunk seizure as a request for service and grounds the trunk T lead to indicate to the calling PBX that the CO is ready to receive digits.

A symmetric signaling scheme used on private

A supervisory signaling scheme used on public

• LS (Loop Start) supervision—A supervisory signaling scheme used between a voice terminal and a PBX in which the voice terminal completes the loop current path. The loop current path is completed with the addition of battery polarity reversal used for answer supervision and a positive/negative 130-V dc signal applied from ground to both tip and ring conductors.

• RB (Reverse Battery) supervision—A supervisory technique on 1-way trunks that uses open and closure signals from the originating end and reversals of battery and ground from the terminating end (normally used on direct inward dialing trunks).

Transmission of Address

With signaling there are three types of transmission of address. Transmission of address is

the method of signaling used to represent digits and/or characters for called numbers, calling

numbers, etc. The methods of addressing are dial pulse (DP), dual tone multifrequency (DTMF), and multifrequency (MF) addressing.

2-27

CHAPTER 2. ARS AND TRUNKS—INSTRUCTIONS AND FORMS

• DP addressing interruptions of a direct or alternating current at the sending end in which the number

of interruptions corresponds to the value of a digit or character (alternating current is not used by PBXs). The interruptions are usually produced by a rotary telephone dial, or may be produced by a sender in a switching system.

Ž DTMF addressing—

of dialing signals of two simultaneous tones. One tone from a low group of four frequencies and the other from a high group of four frequencies correspond to digits, letters, or characters (0 through 9, A through Y, or * and #). One of the tones (1633 Hz) from the high group is a spare.

• MF addressing—

two, out of six to represent ten decimal digits (0 through 9) and five auxiliary signals. MF signals are used for called number addressing, calling number identification, ringback, and coin control.

Transmission of Alerting

Network trunks operate as automatic, immediate start, dial tone, wink start, or delay dial according to the type of start dial signal (alerting) the switch sends out or expects to receive.

The different transmissions of alerting are as follows:

• Automatic—The originating switch sends no digits or start dial signal, expecting the

terminating switch to complete the call. The call is usually completed by the attendant or other service such as Centralized Attendant Service (CAS).

—A means of signaling that consists of regular momentary

Signaling arrangements (commonly known as touch-tone) consist

Signaling arrangements that make use of two frequencies, and only

• Immediate start-The originating switch sends digits immediately, without waiting for

a start dial signal from the terminating switch.

• Dial tone—The terminating switch sends precise dial tone to the originating switch, indicating that the terminating switch is ready to receive digits.

Ž Wink start-The terminating switch sends a wink start (momentary off-hook) signal to

the originating switch, indicating that the terminating switch is ready to receive digits.

• Delay dial—The terminating switch sends a delay dial signal (an off-hook signal followed by an on-hook signal) to the originating switch, indicating that the terminating switch is ready to receive digits.

With digital trunks, signaling schemes are basically the same as for analog trunks when establishing a call. digital trunks. These schemes are handled in a variety of ways to indicate particular calling states, such as on-hook, off-hook, ringing, not ringing, etc., by using “A” and “B” bit timed signaling. channel unit type, far-end channel type, trunk condition (open loop, loop closure, reverse battery, etc.), and whether it is transmit or receive signaling.

“A” and “B” bits carry a 0 or 1 depending on the type of trunk, the near-end

2-28

General

In addition to the preceding, refer to the DS1 Circuit Pack coverage (Chapter 5) for trunkrelated terms associated with DS1 trunk interfaces.

Private Network Trunks

Priate network trunks are referred to as tie trunks. The tie trunks that interconnect the switches of a private network are “universal”

administered with a variety of translation encodes. The originating switch can recognize any

start dial signal (precise dial tone, wink start, or delay dial) that the terminating switch sends. If the originating switch does not receive one of these start dial signals, it can be administered to send digits after an administered time-out interval. The time-out interval is

the amount of time the originating switch waits before sending digits. Tie trunks are further classified according to the type of signal (analog or digital) they carry.

Analog Tie Trunks Analog tie trunks are communications paths that carry voice and voiceband data

communication. The term voice implies that sound is transferred into electrical form and transmitted within an approximate voiceband of 300 Hz to 3400 Hz. Voiceband data implies that data is transmitted within the voiceband and requires a conversion resource (modem) at both ends of the connection. The data transmission rate for analog tie trunks depends on the data-handling capability of the modems in the connection. Other factors that affect the data rate are the number of tie trunks in the connection and the technology of any multiplex

systems used in the facilities. Generally, for data rates up to 300 bps, a connection can have five tie trunks in tandem. For data rates greater than 300 bps up to 2400 bps, a connection can have up to three tie trunks in tandem. For data rates greater than 2400 bps up to 4800 bps, a connection can have up to two tie trunks in tandem.

which means that the trunks can be

Analog tie trunks used in unstitched connections can support up to 9600 bps. A special type of private network tie trunk is a Release Link Trunk. The Release Link Trunk

(RLT) is used between a central or main location and a branch location to provide Centralized Attendant Service (CAS). It functions as a 1-way outgoing circuit from the branch locations and a 1-way incoming to the main location. RLTs participate in the redirection of incoming calls originally directed to the branch location to attendants at the main location and handle call completion back to the branch location.

Another special type of trunk is the Advanced Private Line Termination (APLT) trunk. APLT

provides access to and termination from central office based private networks, namely, Common Control Switching Arrangements (CCSA) and Enhanced Private Switched Communications Service (EPSCS). APLT trunks are physically the same as those used for analog tie trunks where the trunk signaling is compatible with EPSCS and CCSA network switches. The outgoing APLT trunk repeats any number of digits to the private network as dialed. APLT trunks can tandem through the PBX from EPSCS network only, whereas CCSA networks require an attendant to complete the call.

2-29

CHAPTER 2. ARS AND TRUNKS—INSTRUCTIONS AND FORMS

Digital Tie Trunk (DS1 ) The digital tie trunk is a high-speed and a high-volume trunk interface to T1 carrier. It uses

digital signal (DS1 ) on the T1 carrier. By multiplexing twenty-four 64-kbps digital channels onto a single 1.544-Mbps T1 carrier, DS1 offers an economical alternative to the analog tie trunk as well as a high-speed fully digital (without modems) connection between the switches.

The maximum per-channel data rate for DS1 is 64 kbps, and it can carry voice, voiceband data, or high-speed data communications.

The DS1 tie trunk is also used for Digital Multiplexed Interface (DMI). DMI provides highspeed communications over digital transmission facilities between a host computer and System 75 or System 85. The DMI trunk uses the “A” bit for signaling to provide wink-start dial-repeating into the switch and automatic out or 2-way wink start.

Public Network Trunks

Public network trunks are classified according to the type of signal (analog or digital) they carry. Public network trunks are used to connect a private network switch to a public network switch (central office). In reference to a central office, the term “local” applies to a

switch within the local exchange area. An exchange area has a single uniform set of charges for telephone service and may be served by more than one central office (CO). Within an exchange area, a call between any two points is a local call.

Public network trunks also function as “special access” to AT&T Communications (AT&T-C) toll network. AT&T-C provides such services as MEGACOM@ service, MEGACOM 800 service, and ACCUNET® digital service.

Analog Trunks Analog public network trunks are as follows:

• Central Office (CO) Trunk—A 1-way outgoing, 1-way incoming, or 2-way trunk

connecting the switch to a CO within the local exchange area.

• Foreign Exchange (FX) Trunk—A 1-way outgoing, 1-way incoming, or 2-way trunk

connecting the switch to a CO that is outside the local exchange area. These trunks give a caller direct access to a CO outside the local exchange area without having to use the public network.

• Wide Area Telecommunications Service (WATS) Trunk—A 1 -way outgoing or 1 -way incoming trunk connecting the switch to a CO equipped to handle WATS calls. The outgoing trunks allow a customer, for a monthly charge, to place outgoing station-tostation calls to telephones in a defined service area. The service area has one or more geographic areas known as WATS bands. Incoming trunk calls are completed by the attendant or other service.

2-30

• 800 Service Trunk—A 1-way incoming trunk connecting the switch to a CO equipped to handle 800 Service calls (also known as Inward WATS). These trunks allow a customer, for a monthly charge, to receive incoming station-to-station calls from telephones in a defined service area without charge to the caller.

• Direct Inward Dialing (DID) Trunk —A 1-way incoming trunk connecting the switch to a local CO. These trunks allow calls from the public network to complete to terminals (stations) assigned to a private network switch without attendant assistance.

• Direct Outward Dialing (DOD) Trunk—A 1-way outgoing trunk for outgoing calls connecting the switch to a CO. These trunks allow voice terminal (station) users to place calls to a public network CO directly (without attendant assistance).

Digital Trunks The digital public network trunk provides a DS1 interface to the CO over T1 carrier. The DS1

public network trunk provides an interface to CO, FX, WATS, and DID. These trunks provide loop-start and ground start switch CO, FX, and WATS incoming/outgoing type trunks, and reverse battery DID trunks. types with varying characteristics to the same trunk interface. Therefore, it may also connect the switch to a toll office directly using wink start tie trunks for 2-way access to the toll network.

The DS1 interface also allows the assignment of several trunk
