Organization
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:
1.
Contact your Field Assistance and Support Team (FAST).
2.
If a satisfactory answer is not obtained from the FAST center, contact your supervisor.
3.
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
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
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.

Planning
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.
a.
Keep the number of locations to a minimum.
b.
Centrally locate the site or satellite closets among the information outlets to minimize station wiring distances.
c.
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.
d.
The distance between the power supply and the voice terminal cannot exceed 250 feet of 24-gauge wire.
e.
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
a.
The preferred arrangement is to have individual cables supply each site or satellite closet.
b.
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.

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.

The 110-type hardware consists of 110A- and 110P-type hardware. The
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.

110P-Type Hardware
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

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.

CHAPTER 3. EQUIPMENT ROOM DESIGN
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

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.
●
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.

Wall Space Requirements
Approximately 8 inches of horizontal wall space is required for each column of sneak fuse panels. Horizontal wall space must also be provided for emergency transfer units.
3-20
Typical System Equipment Room Floor Plans
Wall Space Requirements for 110-Type Hardware
The trunk/auxiliary field and the distribution field are mounted on the same wall. Each 110P-type terminal block is 8-1/2 inches wide. Vertical patch cord troughs are 5-5/16 inches wide and horizontal patch cord troughs are 23 inches wide.
Each 110A-type terminal block is 10-13/16 inches wide; however, no horizontal patch cord troughs are used and the blocks are shorter than
110P-type terminal blocks. This allows the 110A-type terminal blocks to be stacked. Therefore, the 110A-type hardware requires less space than the 110P-type hardware on a per-station basis.
Wall Space Requirements for 66-Type Hardware
The trunk/auxiliary field and the distribution field are mounted on the same wall.
If the 66-type connecting blocks are being mounted directly on a wall, the space requirements of a 183-type backboard should be used to figure the amount of wall space required for the connecting blocks. This method allows enough space between the connecting blocks for jumper wires and cable connections. The 183A-type backboard mounts four
66-type connecting blocks and is 8-1/2 inches wide and 20 inches tall.
The 183B-type backboard mounts eight 66-type connecting blocks, and is 17 inches wide and 20 inches tall.
When multiple mountings are required, each 166-type mounting is 17 inches wide and 20 inches tall, and each 154A-type mounting is 8-1/2 inches wide and 20 inches tall.
The 187B1 backboard, equipped with pegs, is 17 inches wide and 6-1/2 inches tall.
Equipment Requirements
Cable Slack Manager Requirements
A cable slack manager is 32 inches wide. The quantity of cable slack managers required is determined by dividing the total length of the cross-connect field (in inches) by 32. A partial number of .4 or less should be rounded down, and a partial number of .5 or more should be
3-21
CHAPTER 3. EQUIPMENT ROOM DESIGN rounded up (for example: 2.4 = 2 cable slack managers and 2.5 = 3 cable slack managers required).
110-Type Hardware and Patch Cord Requirements
Table 3-D lists the amount of 110-type hardware required to provide 1-,
2-, 3-, or 4-pair distribution for the station wiring. The 110-type terminal blocks are available in various sizes and the number of stations connected to each block depends on the number of pairs that are run per station.

Frame Mounting 110P-Type Terminal Blocks
The 900-pair 110P-type terminal blocks and the associated patch cord troughs can also be mounted on a free-standing, floor-mounted 1110A2
apparatus mounting frame (Figure 3-16). Each 1110A2 apparatus
mounting frame provides the space to mount five terminal blocks/patch cord troughs on each side of the frame. A cable support structure, apparatus mounting 1110C1, mounts directly on top of the 1110A2 apparatus mounting frame and provides support for all cables routed to and from the frame.

Wall Mounting 66-Type Connecting Blocks
The first column of 66-type connecting blocks should be aligned with
the left side of the switch cabinet (Figure 3-7). This arrangement allows
for orderly growth toward the right side of the cross-connect field.
The connectorized 66-type connecting blocks are factory wired for cable routing from the top so that the cable connector will align with the connector on the connecting block. If cable routing from the bottom is desired, then the connector on the connecting block must be removed and rotated 180 degrees. Then, the connector must be relocated in the previously unoccupied hole because the connecting block leads are not long enough to reach the hole where the connector was previously mounted. The VELCRO® cable retainer must also be relocated.
To install the cross-connect field, proceed as follows:
1. Draw a level horizontal line on the wall 12 inches above the floor

Repeat Steps 2, 3 and 4 until each backboard or connecting block
has been installed.
Note: The 66-type connecting blocks should not be installed more than 78-1/2 inches above the floor.
Installing Cable Slack Managers
To install the cable slack managers (Figure 2-17), proceed as follows:
1.
Place the Z113A cable slack manager against the wall under the
cross-connect field (Figure 3-9), aligning the left side of the cable
slack manager with the first terminal block of the trunk/auxiliary field.
2.
Place the next cable slack manager beside the previously installed cable slack manager. Align the tabs and interlocks, and snap the cable slack managers together.
3.
Repeat Step 2 until all cable slack managers are installed.
Note: Nine holes (¼-inch) are provided in a cable slack manager base in the event earthquake mounting is required. Also, if a cable slack manager base is mounted on an uneven floor, shims may be required to level it and insure proper fit of the covers. Holes are provided in the sides of the base for bolting cable slack managers together. Bolts and shims must be obtained locally.

Routing Cables From Cabinet to Cross-Connect Field
The following guidelines should be followed when routing cables from the cabinet to the cross-connect field.
● When cable routing is to the top/bottom of the cross-connect field, each port cable is connected at the cabinet and then routed along the front trough of the cable slack manager to the connecting/terminal block where the cable is to be terminated.
● Enough slack must be left at the cabinet end of the cable to allow
for proper dressing of the cables (Figure 3-50).
● Route the cable from the cabinet to the wall. Place the cable beside one of the rows of columns in the cable slack manager
(see Note).
Note: Retainers mounted on the columns keep the cable from protruding above the top of the base of the cable slack manager.
● Determine the length of the cable required to reach from the cable slack manager to the assigned connecting/terminal block.
● The cable must be supported on the wall using D rings.
● Cable slack is stored by coiling the cable around the columns in the cable slack manager. The first run should always go across the full length of the five columns in the cable slack manager.
● Connect the cable to the assigned connecting/terminal block.

CHAPTER 3. EQUIPMENT ROOM DESIGN
Installing Coupled Bonding Conductor (CBC) Grounding
A CBC must be tie-wrapped to all trunk cables. The CBC connects the cabinet single-point ground block to the approved ground located nearest the telephone company owned protector block at the building
entrance facility (Figure 3-59).
Note: The CBC is a conductor that is connected to ground and run adjacent to the pairs in an inside wiring cable. The mutual coupling between the bonding conductor and the cable pairs reduces potential differences in terminating equipment. The conductor consists of a No. 10 AWG wire that is tie-wrapped to the inside wiring cable.
APPROVED GROUNDS
An approved ground is an acceptable medium for grounding the building entrance protector, entrance cable shield, or single-point ground of electronic PBX equipment. If more than one type of approved ground is available on the premises, the grounds must be bonded together as required in Section 250-81 of the National Electrical Code.
Metal Frame of the Building — the metal frame of the building where it is effectively grounded by one of the following grounds: acceptable metallic water pipe, concrete encased ground, or a ground ring.
Acceptable Water Pipe — a metal underground water pipe, at least 1/2 inch in diameter, in direct contact with the earth for at least 10 feet. The pipe must be electrically continuous (or made electrically continuous by bonding around insulated joints, plastic pipe, or plastic water meters) to the point where the protector ground wire is connected. A metallic underground water pipe must be supplemented by the metal frame of the building, a concrete encased ground, or a ground ring. If these grounds are not available, the water pipe ground can be supplemented by one of the following types of grounds:
●
Metal underground gas piping system—an electrically continuous metal underground gas piping system that is uninterrupted with insulating sections or joints and without an outer nonconductive coating
●
Other local metal underground systems or structures—local underground structures such as tanks and piping systems
3-86
Equipment Room Hardware And Cabling Installation
●
Rod and pipe electrodes—a 5/8 inch (solid rod) or 3/4 inch
(conduit or pipe) electrode driven to a minimum depth of 8 feet
● Plate electrodes—expose a minimum of 2 square feet of metallic surface to the exterior soil.
Concrete Encased Ground — an electrode encased by at least 2 inches of concrete and located within and near the bottom of a concrete foundation or footing in direct contact with the earth. The electrode must be at least 20 feet of one or more steel reinforcing bars or rods 1/2 inch in diameter, or at least 20 feet of bare, solid copper, No. 4 AWG wire.
Ground Ring — a buried ground that encircles a building or structure at a depth of at least 2-1/2 feet below the earth’s surface. The ground ring must be at least 20 feet of No. 2 AWG, bare, copper wire.
APPROVED FLOOR GROUNDS
Approved floor grounds are those grounds on the floor of a high-rise building suitable for connection to the ground terminal in the riser closet and to the PBX equipment single-point ground terminal. Such grounds may be one of the following:
● Building steel
● The grounding conductor for the secondary side of the power transformer feeding the floor
● Metallic water pipes
● Power feed metallic conduit supplying panel boards on the floor
● A grounding point specifically provided in the building for the purpose.

Station Wiring Design
A brief description of each of the above listed items follows. The station
wiring labels and their use are described in Chapter 4. Ordering
information is not provided for station cables and information outlets.
The ordering information for this equipment is available in the Premises
Distribution System Equipment and Supplies Catalog.
Information Outlets
Information Outlets are 8-pin modular wall jacks. Most of the outlets are wired with push-on connections. Information outlets are also available that connect to a double modular plug-ended 4-pair station cable run from the cross-connect field, a site/satellite location, or an adapter.
Station Cables
For clarity in describing the wiring in this guide, station cable is either
25-pair cable, multiple 25-pair cable, or 4-pair D-inside wire (DIW) run from the equipment room, a site/satellite location, or an adapter to the information outlets. The following types of station cable are available.
●
Connectorized 25-pair station cable—This cable is used between the equipment room and the site/satellite locations or adapters.
For 110-type hardware, use an A25D cable (male to male) between the equipment room and a satellite closet, and use a
B25A cable (male to female) between the equipment room and a site closet or adapter. For 66-type hardware, use an A25B cable
(female to female) between the equipment room and a satellite/site closet or adapter. The A25B cable is available with connectors on each end (double-ended), and also with a connector on only one end (single-ended). Use the single-ended cable when the leads are punched down on the connecting blocks.
● Connectorized multiple 25-pair station cable—This cable can be used between the equipment room and the site/satellite locations or adapters. This cable consists of individually sheathed 25-pair cables with a factory-installed 25-pair connector on each end. For
110-type hardware, use a male to female cable to connect between the equipment room and a site location or adapter, and use a male to male cable to connect between the equipment room and a satellite location. For 66-type hardware, use a female to female cable to connect between the equipment room and a
3-91
CHAPTER 3. EQUIPMENT ROOM DESIGN site/satellite location or adapter. Staggered-finger cables are recommended for all multiple 25-pair station cables.
Staggered-finger cables are available in both double-ended and single-ended types.
●
Bulk Cable—This cable is the same as the connectorized 25-pair cable or multiple 25-pair cable; however, the bulk cable is not equipped with connectors. Use this cable between the equipment room and satellite closets when both are equipped with punch-down type terminal/connecting blocks.
●
Nonconnectorized 4-pair station cable—Use this cable when
4-pair station cables are to be field-terminated on the 110-type terminal blocks/66-type connecting blocks in the equipment room or satellite closet and the information outlets require push-on connections.
●
Single modular plug-ended 4-pair station cable(Figure 3-60)—Use
this cable between adapters and information outlets that require push-on connections. It can also be used when 4-pair station cables are field-terminated on the 110-type terminal blocks/66-type connecting blocks in the equipment room or satellite closet and modularly connected to information outlets.

Station Wiring Design
Satellite Locations
Satellite locations are closets that provide an administration point (using cross-connect equipment) for station cables and where adjunct power may be applied. The station cable circuits from the equipment room cross-connect field are 3-pair. The hardware at the equipment room has been described previously. At the satellite location, 4-pair circuits run to the information outlets. The hardware used at the satellite location is
110-type terminal blocks/66-type connecting blocks.
Satellite Locations Using 110-Type Hardware
Each terminal block has a 3-pair (white field) and a 4-pair (blue field) located on the same terminal block.
The 110A-type terminal block that can be used in the satellite closet is the 110AE1-75FT. It must be field-terminated to both the white and blue fields.
The 300-pair 110P-type terminal blocks that can be used in the satellite closet are the:
LI 110PE1-300CT—connectorized on both the white and blue fields
●
110PE1-300CT/FT—connectorized on the white field and field-terminated on the blue field
● 110PE1-300FT—field-terminated on both the white and blue fields.
The 900-pair 110P-type terminal blocks that can be used in the satellite closet are the:
●
110PE1-900CT/FT—connectorized on the white field and field-terminated on the blue field
●
110PE1-900FT—field-terminated on both the white and blue fields.
3-97
CHAPTER 3. EQUIPMENT ROOM DESIGN
Satellite Locations Using 66-Type Hardware
The 3-pair station circuits from the equipment room are terminated on a 66-type connecting block in the satellite closet white field, and then cross-connected to a 66-type connecting block in the blue field. The
4-pair station circuits from the information outlets are terminated on the satellite closet blue field. The following 66-type connecting blocks can be used in a satellite closet;
● 66M1-50 connecting block
●
157B connecting block
●
154A-type backboard
● 166A-type bakcboard
Station Circuit Distribution From Equipment Room
The following information explains the station circuit distribution from the equipment room to the information outlets for new wiring installations. Connection diagrams are provided to show the options for running and connecting the station cables.
If most of the telephones/voice terminals that require remote powering are within 250 feet of the equipment room, 4-pair station circuits are run from the equipment room to the information outlets. If this is not the case, or if the customer requires 2-point administration, 3-pair station circuits are run from the equipment room to satellite locations. Then, the
4-pair station circuits are run from the satellite locations to the information outlets.
4-Pair Station Circuits
Four-pair circuits can be run directly from an equipment room
cross-connect field to a 258A or BR2580A adapter as shown in Figure
3-64. The 4-pair station cables connect the adapter to the information
outlets.

CHAPTER 3. EQUIPMENT ROOM DESIGN
The 4-pair station cables can be run, directly from the equipment room to the information outlets if 4-pair terminal blocks are used in the distribution field (Figure 3-65). The station cables must be field-terminated on the 110-type terminal blocks/66-type connecting blocks. If 110-type terminal blocks are used with a modular plug-ended station cable, an adapter can be connected directly to the 110-type
terminal block connectors (Figure 3-66).

Station Wiring Design
Layout
Locating Information Outlets
The customer or marketing representative must provide floor plans showing the information outlet locations and types (flush- or surface-mounted) required. The floor plans must also show a complete overview of all conduit and cabling facilities in the building.
Locating Satellites and Sites
Use the following information when determining site, satellite, or adapter locations.
a. Keep the number of locations to a minimum.
b . To minimize the station wiring distances, centrally locate the sites/satellites, or adapters among the information outlets.
c . Site/satellite locations must be easily accessible and contain ac power receptacles.
Adapter Requirements
One 258A/BR2580A adapter is required for each 25-pair station cable containing 4-pair station circuits. One 356A adapter is required for each
25-pair station cable containing 3-pair station circuits.
Hardware Requirements
Hardware requirements are the same as for the equipment room.
Sizing 4-Pair Station Cables
Use the scale of the floor plan to determine the approximate length of the station cables required per the standard Premises Distribution
Systems wiring concepts.
3-107
CHAPTER 3. EQUIPMENT ROOM DESIGN
Sizing 25-Pair and Multiple 25-Pair Station Cables
Use the scale of the floor plan to determine the approximate length of each 25-pair station cable. The 25-pair station cables must be selected and properly sized to make maximum use of the hardware at the equipment room or satellite location.
When using 110-type hardware, use 25-pair B25A cables to connect adapters directly to the equipment room cross-connect field or satellite location. Staggered-finger cables, equipped with factory-installed 25-pair connectors at both ends (male to female), are recommended for use when multiple 25-pair cables are to be used between the equipment room or satellite location and the adapters. B25A cables are required at the equipment room or satellite location to connect the staggered-finger cables to the 110-type terminal blocks.
When using 66-type hardware, use 25-pair A25B cables to connect adapters directly to the equipment room cross-connect field or satellite location. Staggered-finger 25-pair cables (double- or single-ended), are recommended for use when multiple 25-pair cables are to be used between the equipment room or satellite location and the adapters.
B25A cables are required at the equipment room or satellite location to connect the double-ended (female to female) staggered-finger cables to the 66-type connecting blocks.
Use the following information to determine the cable size (cable pairs) required for either 3-pair or 4-pair circuits. Note the length and size on the floor plan to aid in the ordering and installation of the station cables.
3-Pair Station Cable Circuits
To determine the size of station cables containing 3-pair circuits, multiply the number of 3-pair circuits required at the satellite location by
3.5. Then, using the minimum size cable requirement, round up the cable size requirement to the next highest available cable bundle size.
This will provide additional pairs for growth and compensate for the fact that every twenty-fifth pair in a cable is not used.
3-108
Station Wiring Design
4-Pair Station Cable Circuits
To determine the size of station cables containing 4-pair circuits, find out how many information outlets are served by the equipment room cross-connect field or satellite location cross-connect field. Multiply the number of information outlets by 4 (see Note). Then, using the minimum size cable requirement, round up the cable size requirement to the next highest available cable bundle size.
Note: This formula may not compensate for the unused twenty-fifth pair in all cases. If not, you must allow for it.

Digital Out-of-Building Voice Terminals
Protection is required at both building entrances for digital out-of-building voice terminals. There are 6 different primary protectors that can be used with the required secondary (data link) protector to protect digital voice terminals in an out-of-building environment.
Primary protectors have a surge breakdown voltage range of 200 to 800 volts at 100 volts per microsecond depending on the type of device. Sneak current protection is also required. It can be provided by a 4-type protector or a 3type protector plus a separate sneak current protector. The 4-type primary protector is equipped with a heat coil for sneak current protection. The 4type primary protector is the preferred device because it eliminates the need to evaluate the interbuilding cable runs and its vulnerability to power cross faults. When the 3-type primary protector is used, a separate sneak current protector is required.
The secondary (data link) protector is required in addition to the primary protector and is installed on the equipment side of the primary protector.

Installing Emergency Transfer Units and Associated
Telephones
Requirements
Emergency transfer capability is provided by a transfer unit mounted on the wall next to the trunk/auxiliary cross-connect field.
Only 500- or 2500-type telephones can be used for emergency transfer.
For R1V2/V3 switches, 500-and 2500-type telephones can also be used as normal extensions. For R1V1 systems, 500-type telephones are used when the CO has only rotary dialing service and they cannot be used as normal extensions. Emergency transfer capability may be provided on CO and Wide Area Telecommunications Service (WATS) trunks.
The following transfer units are available:
●
574-5 power transfer unit—Each unit serves up to five power failure transfer telephones. The unit provides automatic ground start.
● Z1A emergency transfer unit—Each unit serves up to six power failure transfer telephones. A ground-start switch is required at each preselected telephone when ground start trunks are used.
At the cross-connect field, the transfer units are connected to a yellow terminal row/connecting block in the trunk/auxiliary field. The units are powered (-48 V dc) from the EM TRANS RELAY PWR terminals. There are seven EM TRANS RELAY PWR terminal pairs which allows powering of up to seven transfer units.
Installing the 574-5 Power Transfer Unit
The 574-5 power transfer unit has connection for five emergency transfer telephones and is compatible with both loop start and ground
start trunks. Ten slide switches in the center of the unit (Figure 4-25) are
set for the trunk type (two per trunk). The switches are set at the factory for ground start trunks.

CHAPTER 5. AUXILIARY EQUIPMENT INSTALLATION
Installing Loudspeaker Paging Access—278A Paging
Adapter
Requirements
Access to loudspeaker paging is provided by an information outlet. The switch side of the cross-connect field is connected to a 278A adapter.
The 27A adapter is designed to operate on -24V dc. If it is to be operated on -48V dc, it must be modified with a D-181321 kit of parts.
The adapter is mounted in the auxiliary cabinet, if one is available. If an auxiliary cabinet is not available, a connectorized wiring block must be locally engineered to replace the auxiliary cabinet ED-1E443-10 intra-connection panel. Six leads (T, R, SZ, SZ1, S, and S1) connect the adapter to a TN763 auxiliary trunk circuit pack located in a port carrier.
A TN763 circuit pack contains four ports.
Figure 5-2 shows the connections for the Loudspeaker Paging feature.
The connections are for one zone. Repeat the connections for each paging zone.
The connections shown in Figure 5-2 are used when the loudspeaker
interface equipment is not located in the equipment room. If the loudspeaker amplifier is located in the equipment room, the connections do not have to be routed through the cross-connect field.
