Use of Guide

This guide provides information for planning, designing, and installing a cost-effective wiring installation that allows moves, changes, and additions to be made quickly and easily. To make the best use of this guide, take the time to read it thoroughly and become familiar with its contents and organization. For quick access to information needed to answer most questions, refer to the table of contents and locate the specific item in question.

To answer questions requiring more information than this guide contains, consult the documents listed previously in this introduction section. If you need additional help, contact the Premises Services Consultant (PSC).

For further technical assistance, the recommended channel for AT&T

System Technicians is as follows:

Contact your Field Assistance and Support Team (FAST).

If a satisfactory answer is not obtained from the FAST center,

2. contact your supervisor.

Your supervisor should contact the regional staff, if necessary.

Equipment

Most of the items specified in this guide are available through the local

AT&T Marketing Branch Office (MBO). However, some common use

hardware items may have to be obtained from other sources.

System Wiring

System wiring plays a significant role in customers’ information systems. Technological innovations enable both voice and data transmission to be provided through the system wiring. Also, the system wiring has been simplified by reducing the number of cable pairs required by voice terminals equipped with enhanced feature options.

This guide provides planning, ordering, and installation guidelines for a

system Uniform Wiring Plan (Figures 1-2 and 1-3) using 110-type or

66-type hardware.

1-5

Page 15

CHAPTER 1. INTRODUCTION

The system switch ports for data and voice terminals require three pairs of wire per circuit. Voice terminal adjuncts require an additional pair for remote powering. To provide maximum flexibility for voice terminal changes, rearrangements, and powering, all data and voice terminal information outlets are wired with 4-pair cable. With proper administration, this will allow any voice terminal to be located at any information outlet.

Cross-Connect Hardware Selection

For new wiring installations, the following cross-connect hardware is available for use in the system. Each item lists certain considerations

that should help to select the appropriate hardware.

1. 110P Hardware

●

Patch cord design allows customer to administer cross-connections

●

Requires some technical skill to administer cross-connections

2. 110A Hardware

●

Design does not permit customer participation in cross-connect administration—requires technically skilled personnel to administer cross-connections

●

Hardware is less expensive than the patch cord systems, but installation and administrative costs are greater

3. 66-type Hardware

●

Design does not permit customer participation in cross-connect administration—requires technically skilled personnel to administer cross-connections

●

Hardware is less expensive than the patch cord systems, but installation and administrative costs are greater

Obviously, the customer’s interest and preference for administering cross-connections (because of likely lower total annual costs, as well as the capability to administer the cross-connections at the most convenient time) should be given primary consideration in recommending cross-connect hardware.

Figure 1-4 shows a block diagram of the equipment required to install a System 75 or 75 XE switch. The sites shown in Figure 1-4 are physical locations (closets) for pass-through connections where adjunct power may be applied. The satellite is a physical location (closet) where cross-connect administration can take place and adjunct power may be applied.

Wiring Hardware Changes

All jobs engineered by PSCs based on customer requirements and

preferences should not be redesigned by the Field Services Organization (FSO) without approval by the PSC/MBO. If changes are required, a change order must be issued to ensure correct billing.

1-10

Page 20

Planning

The following information will help you design a uniform wiring plan with

growth potential. The plan is simple, flexible, easy to administer, and reasonable in cost.

Job Aids

Blueprints (floor plans) are important when planning, designing, and

installing station wiring. The floor plans (Figure 1-5) provide a complete view of all conduit and other cabling facilities in the building. These facilities should be considered when planning site or satellite locations

and cabling.

Voice Terminals

The number of information outlets to be installed per voice terminal location is determined by customer requirements. It may be advantageous to install any additional information outlets required for future growth or voice terminal rearrangements during the initial installation.

To begin designing the station wiring, show the following information on the floor plan(s):

●

Location of each information outlet and associated voice terminal

type if known (analog, hybrid, or digital)

●

Any associated voice terminal adjuncts or modules and the

required powering arrangements.

Planning

Site or Satellite Closets

When determining the location of site or satellite closets, use the following information as a guide. Show the locations on the floor plan.

Keep the number of locations to a minimum.

Centrally locate the site or satellite closets among the information

outlets to minimize station wiring distances. Site or satellite closets must be easily accessible and contain

enough ac power receptacles to serve the equipment that will be located there. Voice terminals equipped with adjuncts that require power can be remotely powered from:

●

a site or satellite location

●

from the main equipment room

●

information outlets.

The distance between the power supply and the voice terminal

cannot exceed 250 feet of 24-gauge wire.

Locks should be provided for the site or satellite closet doors to

prevent tampering with the equipment.

Cabling Facilities

The method of riser cable distribution between the main equipment

room and site or satellite closets is usually determined by the type of

cabling facilities (riser closets, conduit size, cabling shafts, etc.) in the

building (Figure 1-6).

The preferred arrangement is to have individual cables supply each

site or satellite closet.

A second method is to have one or two large cables supply all the

site or satellite closets. This requires that smaller cables be installed between the main riser cable and the site or satellite closet. These smaller cables are then spliced into the main cable.

Determine the type of cabling required and mark the type and routing on

the floor plan. Also, show any additional cabling facilities required for

riser and terminal cabling.

Figure 2-3. 110-Type Index Strip With Connecting Blocks

The connecting blocks (Figure 2-3) are equipped with clips that slice the insulation of the wires when the connecting block is pushed onto the index strip. The top of the connecting blocks are used for cross-connections. When a wire is punched onto the top of the connecting block, it makes a connection, through the connecting block, to the wire in the index strip.

The connecting blocks come in 3-, 4-, and 5-pair blocks. When 3- or 4-pair connecting blocks are used, the last connecting block on each index strip must be one pair larger to complete the 25-pairs. The ordering codes determine the type of connecting blocks received with a terminal block. The 110-type wiring blocks allow for individual 3- and 4-pair connecting blocks to be disconnected for testing without disturbing adjacent circuits.

110P-type hardware uses patch cords to make cross-connections. This allows the customer to make cross-connections. The 110A-type hardware uses individual jumper wires for cross-connections. For this reason, the 110A-type hardware is not intended for customer usage because it requires technically skilled personnel to make cross-connections. The 110A- and 110P-type hardware should not be mixed together in the same room.

110A-Type Hardware

The 110A-type hardware consists of a 100- or 300-pair wiring block and the associated connecting blocks. The 100-pair wiring blocks (Figure 2-4) are arranged for field termination. The 300-pair wiring blocks

(Figure 2-5) come in both field-terminated and connectorized (with 6-foot cable stubs) types.

The 110P-type hardware consists of 100-pair wiring blocks, separated by horizontal patch cord troughs, mounted on a panel. The P-type comes in both 300- and 900- pair configurations which can either be connectorized or field terminated. The 110P-type terminal blocks are made up of alternate rows of 110-type wiring blocks and horizontal

jumper troughs arranged in a vertical column with the troughs located

above the wiring blocks. At the bottom of the terminal block is a partially closed duct. The field-terminated hardware must be assembled (troughs and wiring blocks must be fastened to the back panel); the connectorized terminals come fully assembled and ready for mounting. A 300-pair connectorized terminal block is shown in Figure 2-6.

There are two types of 900-pair connectorized terminal blocks: one has a connector field at the top; the other is connectorized with a 40-inch length of cable terminated with a female 25-pair cable at the bottom (Figures 2-7 and 2-8).

66-Type Hardware Description

The 66-type hardware consists of non-connectorized or connectorized connecting blocks. The connecting blocks can be mounted individually or in multiple arrangements. All 66-type hardware uses the same basic connecting block, a 66M1-50.

66M1-50 Connecting Block

The 66M1-50 (Figure 2-12) connecting block is a plastic connecting

block containing quick connect terminals sized to terminate 20 to 24 gauge wire. It has 50 rows of terminals with four terminals in each row. The first two and last two terminals of each row are connected together and each row is split between the second and third terminals (Figure 2-12). These terminals provide space to terminate one 25-pair cable and the associated jumpers. The terminals slice the insulation of the wires when the wires are punched onto the terminals. The standard termination for a 25-pair cable on a 66M1-50 connecting block is shown in Table 2-A. The 66M1-50 connecting block can be mounted directly on

2-23

Cable Slack Managers

General

The cable slack managers (Figure 2-17) are raised floor units that are used for cable distribution and cable slack storage between the switch cabinets and the cross-connect field. They can also accommodate a limited amount of slack in station cables. Power cables from the switch cabinets are also run through/from the cable slack managers.

Note: Cable slack managers are not required when the switch cabinet is installed on a raised computer floor. The station cables and the cables from the switch cabinets are routed under the computer flooring to the cross-connect field.

The cable slack managers have tabs and interlocks that allow adjacent cable slack managers to interlock together. Retainers mounted on columns inside the cable slack managers keep the cables from

protruding above the top of the base. The cable slack managers are

coded as housings and two types are available.

A 5-foot line cord provides ac power to the 346A1 power panel. Service

to the ac receptacle must be provided by a dedicated (nonswitched)

20-ampere circuit. A maximum of four power panels can be connected to a 20-ampere circuit.

Note: Electrical codes of Chicago and Cook County, Illinois

require the use of a metallic 346B1 power panel equipped with a

fused ac power cord (POP-6/217 by JDS Product).

Each 346A power unit contains four power jacks. A slide switch is located between the top and bottom jacks. When the slide switch is in the down position, 10 watts of power is available at both jacks. When the slide switch is in the up position, 20 watts of power is available at the jack above the switch. The jack below the switch has no power.

Note: If two consoles are connected to a power supply, and an

addition is made that requires a 20 watt source, remove the second console and move the power supply switch to the 20 watt position. Connect the second console to another power supply.

CHAPTER 3. EQUIPMENT ROOM DESIGN

General

The System 75—System Description (555-200-200) or System 75

XE—System Description (555-201-200) provides equipment room

specifications for temperature, humidity, air purity, lighting levels, and grounding. They also provide information on the floor and wall space required for the switch and the associated peripheral equipment that is to be installed in the equipment room. For completeness, some of the

information contained in these documents is repeated in this guide.

Hardware Equipment Room Applications

In the equipment room, the 66-type/110-type hardware is used for the cross-connect field which consists of a trunk/auxiliary field and a distribution field (port, auxiliary, and station).

Trunk/Auxiliary Field

The trunk/auxiliary field contains three distinct cross-connect areas:

●

The green field terminates the network interface leads (from the

CO) and provides the terminals to cross-connect the CO leads to the purple or yellow fields as required. A single row of the 66-type connecting block/110-type terminal block can terminate twenty-four 1-pair, eight 3-pair, or twelve 2-pair trunks.

●

The purple field terminates the trunk circuits from the switch with WP-90929, List 1 or 3 (110-type terminal block) or WP-90929, List

2 or 4 (66-type connecting block) concentrator cables. Also, 25-pair cables can be used to terminate trunk circuits from the

switch with each trunk circuit pack connecting to one 25-pair row of the 66-type connecting bIock/110-type terminal block. Each 66-type connecting block/110-type terminal block row can terminate twenty-four 1-pair, eight 3-pair, or twelve 2-pair trunks.

●

The yellow field provides cross-connection terminals for all

miscellaneous leads from the switch, such as alarm monitors, emergency transfer relay power, attendant console power, and

Initialization and Administration System (INADS) trunk. This field is also used for emergency transfer wiring, applications processor (AP) alarms, paging equipment, music sources, etc.

Trunk/Auxiliary Field (110-Type Hardware Only)

Figure 3-1 shows two typical 300-pair terminal block configurations of

110-type hardware arranged for use in the trunk/auxiliary field. One 300-pair terminal block will terminate 96 three-pair circuits and two 300-pair terminal blocks will terminate 192 three-pair circuits.

●

110PC1-900CT which is equipped with 36 female 50-pin connectors. The connectors are mounted at the top of the terminal block. This can be used if cable routing from the top is desirable.

Distribution Field

The distribution field contains four distinct cross-connect areas:

●

The purple field (port field) terminates 25-pair cables from the switch. Each line circuit pack connects to one 66-type connecting block or to one 25-pair row of the 110-type terminal block. One 25-pair cable is required for each line circuit pack.

Note: This is the case except for the 16 port analog line

circuit pack and the MET line circuit pack. The 16-port analog line circuit pack requires an adapter cable to connect from one connector on the switch to two 25-pair connectors on a 66-type connecting block/110-type terminal block. Two

MET line circuit packs require a concentrator cable to connect from two connectors on the switch to one 25-pair connector on a 66-type connecting block/110-type terminal block.

3-4

●

The yellow field (auxiliary field) terminates all 25-pair cables from the auxiliary cabinet and the AP. The yellow field is located in the lower right-hand corner of the distribution field.

●

The white field (station field) terminates the station wiring. The white field indicates 3-pair station circuits (eight circuits per 25-pair cable) that are routed through a satellite closet.

●

The blue field (station field) also terminates station wiring. The blue field indicates 3- and/or 4-pair station circuits (eight or six circuits, respectively, per 25-pair cable). The fourth pair, of the 4-pair station circuit provides adjunct power from the cross-connect field on an as-needed basis to terminals within 250 feet (wire length) of the cross-connect field.

Distribution Field (66-Type Hardware Only)

Figure 3-7 shows a typical cross-connect field using 66-type hardware. It is possible that only a few 66-type connecting blocks will be required in the trunk/auxiliary field for the green and yellow fields. For this reason, if 157B connecting blocks mounted on a purple 183-type or 166-type backboard is used as the trunk/auxiliary field, then some of

the extra connecting blocks in the purple field can be used as the green

and yellow fields to save ordering extra backboards and connecting blocks. When this is done, the green and yellow fields should be clearly identified to avoid confusion. When white backboards are required for cross-connections with a satellite closet, they must be ordered from an outside vendor. If a blue backboard is used for these cross-connections, then the part of the blue field that is functionally used as the white field, should be clearly identified.
