the rack (e.g. 0102.02.23) and the connection point on the device.

7.5. Cable Installation (See Cabling Standard or associated engineering standard for more detail on cable installation)

This section covers the general requirements for installing switchboard, DS1, coaxial, LAN, and

power cable, misc wire, and the routing of cable and cable segregation.

The Contractor shall provide all reel jacks, connector installation tools and other equipment

necessary to complete the cable installation. All cable installation material and tools shall be kept

away from existing equipment during pulling operations.

When new runs are being installed, the cables shall be protected from abrasion damage by use of

sheet protection or by use of pulling horns. Where the new cables may contact existing cables,

hanger rods and other points of contact, sheet protection shall be installed.

Wire with rubber or neoprene outer jackets must be protected with fiber before securing with

lacing cord at each point the cable is secured on the cable ladder and vertical supports.



Cable that is run unsecured, can only be Signal or Alarming cables installed, on cable tray must

lie reasonably flat at in the center of the tray. The cable tray must be equipped with

nonconductive panning sized to fit properly in the cable ladder. Side horns or supports must be

installed to the cable ladder and cable may NOT lie above the height of the side horn. The side

horn may not be any longer than half the width of the cable ladder. Cables shall occupy the same

relative position on the tray at turns or bends. Power cables can never run unsecured in a

Windstream office

Additional lacing shall be installed, with Windstream approval, at locations where it appears that

the cable may curl, droop, spread, or where the wire will not stay parallel.

Use temporary blanketing material to protect all existing equipment from falling dirt during the

cable pulling process or drilling into the ceiling.

Where cables turn corners, the cables shall be temporarily secured with enough slack to permit

cable grooming during final securing.

During pulling operations, the ends of every cable shall be taped to protect the installer from cuts

and abrasions and to prevent electrical contact with energized equipment. There shall be enough

personal to safely handle and control large cable during installation.

All cables shall be installed with adequate temporary restraints to prevent injuries or equipment

damage from falling cable.

Cables that are to remain un-terminated shall be neatly coiled in the cable tray above the

destination equipment rack. Apply a temporary label identifying the source and final destination

of the un-terminated cable. Power cables fuse must not be installed, the circuit breakers must be

in the OFF positions, and tagged “DO NOT TURN ON”

At no time should cables or wire be supported by, threaded rod or conduit, two-bar or any support

material. All threaded rod must have cable protection tubing on the threads above the cable ladder

the width of the cable ladder at a minimum to prevent damage to the cable insulation.

Cable trays and other unapproved elevated work surfaces shall not be used to support installation

personnel or pulling equipment.

Unless otherwise stated by the Windstream Project Engineer a service loop of at least 12 inches,

which must be neatly dressed in, be maintained in all cables after connecting operations are

completed so that they may be removed and reconnected if necessary.

Wire shall be dressed in such a manner as to avoid excessive strain and congestion, to ensure

accessibility for maintenance and future applications, and to maintain clearance between

terminals.

Cables should not be twisted or bent in such a way that might cause damage to the cable. No

cable is to be installed with sharp 90 degree bends, installation of cables shall have shallow

bending radius and the bend radius chart in section 7.5.5 shall be the standard.

All cable in a relay rack must run vertically up to the ladder rack or fiber tray and over to the next

relay rack. Under no circumstances can cable be run directly between relay racks. When going

up to the ladder rack cable must come up over the side and never between ladder rack rungs.

7.5.1. Blocked Cable Runs

If a blocked cable run is encountered, contact Windstream for instructions.



7.5.2. Cable Protection

Cables shall be protected from damage due to abrasion or compression at points of contact with

cable trays, hanger rods, cable falls to equipment, within equipment and all other locations where

the cable may become damaged.

Use sheet or formed fiberboard (sometimes-called fish paper) at all points where cable damage

may occur. The tube shall be at least as long as the cable may be stacked.

Use two sheets of 1/64" or one sheet of 1/32" thick fiber at all pressure points along the cable.

Secure the fiber to the contacting surface with twine.

7.5.3. Securing Cables with Twine

All temporary labels shall be removed prior to final sewing, and all temporary supports shall be

removed as cables are secured in.. Cables that are installed in trays with retaining brackets need

not be stitched except where cables exit the tray.

Use 9 or 12-ply waxed nylon cord for all sewing and banding operations.. The installer is to use

the correct number of strands of 9 or 12-twine to properly secure the cable being installed. Cables

will be laced using the Kansas City stitch and/or Chicago stitch.

Twine shall be tensioned just tight enough to hold cables in-place but not so tight that the outer

insulation of the cables is deformed. Cables damaged by improper lacing will be replaced at the

contractor’s expense.

Secure cables and wire run on horizontal tray type cable trays at the first, last, and alternate rung

so that the cable is lay uniform the length of the run, also additional laces may need to be added

to achieve proper installation. Secure cables and wire run on vertical trays and inverted horizontal

cable trays at every rung.

The unsupported wire or cable shall not sag greater than 0.5"between supports.

7.5.4. Nylon Cable Ties

Nylon cable ties may be used for securing of cables in the Windstream network but their use must

meet Windstream standards. The use of Nylon cable ties in any Windstream facility must have

the Windstream Project Engineer’s approval and may require higher Windstream management

approval BEFORE installing them. Application of nylon ties shall not cause deformation of the

cable insulation or jacket. Nylon cable ties may never be used to permanently secure any DC

Power cables to the cable ladder or nylon cable ties are not to be used for banding or securing

fiber optic jumpers or cables.

Note: Fiber optic jumpers that need to be secured outside of the fiber protection will be

secured with Velcro ties.

Cable Ties shall be tensioned just tight enough to hold cables in-place but not so tight that the

outer insulation of the cables is deformed. Cables damaged by improper uses of cable ties will be

replaced at the contractor’s expense.

Cable Ties used for banding and securing of cable, fiber protection, PVC protection etc., shall be

of adequate size, type, strength, etc., for the particular application. Cable ties shall not exceed the

manufacture’s specification for minimum or maximum inside diameters and/or tension

requirements. Tensioning and cutting of cable ties shall be accomplished using an approved

tensioning and cutting tool (example: Greenlee Cable Tie Installation Gun). The tool shall be a

continuous variable tension type to accommodate variable size ties.



CAUTION: Diagonal wire cutters or cutting devices, other than the approved

tool, shall not be used for cutting the end of cable ties since this may result in exposing

hazardously sharp ends

The cut end of a cable tie shall not protrude past the locking head. Under no circumstances shall a

cable ties have a sharp or jagged cut ends protruding from the locking head. A cable tie is

considered to have sharp or jagged ends when it is sharp to the touch

Secure cables and wire run on horizontal tray type cable trays at the first, last, and alternate rung.

Secure cables and wire run on vertical trays and inverted horizontal cable trays at every rung.

The unsupported wire or cable shall not sag greater than 0.5"between supports.

7.5.5. ISP Cable Bending Radius

7.6. Cable Routing and Segregation on Cable Tray

The sequence of cable installation should be planned to minimize crossovers and undesired

stacking of cables. Placement of cables on the cable tray should produce an evenly stacked and

evenly dispersed cable run along the cable tray.

Cables shall be uniformly placed when making turns in the cable tray. Short cuts will not be

allowed.

At sites where the cable tray is located over the equipment, the front side will be used for express

cables since most cables terminate on the rear. Waterfall the cable over the edge of the tray for

units in the lower rack spaces.

At sites where cable tray is located over the wiring aisle, the center of the tray will be used for

express cables. Cables to equipment on either side of the aisle will be routed down the

appropriate side of the tray. Waterfall the cables over the edges of the tray and not through the

tray.

Cables shall exit the cable tray over the side of the stringer. Cables shall not exit the tray through

the cable tray rungs.

All cable shall be protected at break-off points, cable tray stringers, etc., with formed fiber paper

or two layers of sheet fiber, tied into place with lacing cord.

Cables shall be laced to each tie bar on the vertical run in the equipment bay. Nylon cable ties

will not be used to secure cables. Nylon cable ties may be used to assist in the placement of

cables as long as all cable ties are removed upon completion.

Wire shall be carefully formed to avoid excessive strain and congestion, to insure accessibility for

maintenance, and to maintain clearance between terminals.

Spares and unused pairs will be left long enough to reach any circuit served by that cable, folded

back, and laced into the existing form.

7.6.1. Mixing Cable On Cable Tray

Switchboard, DS1, coaxial, and LAN cable along with misc wire can be run and mixed on a

common cable tray. Power cable including misc wire for small amperage fusing shall be run on a

separate cable tray dedicated to power. No un-fused/battery power cable is to be run with

fused/protect cables, no exceptions. All power cables pairs -48 VDC and Return shall be run

together.



7.6.2. Cable Pile-up on Cable Tray

Based upon 5-foot intervals between supports, the permissible pile-up for cabling on horizontal

cable tray is as follows:

Table 2 - Signal Cable Pile-up

13" – 24" 12" 15"

25" – 36" 12" 15"

7.7. Cable Routing and Segregation within Equipment Racks

7.7.1. Switchboard Cable

Switchboard cable, also referred to as Unshielded Twisted Pair – (UTP) cable and tightly twisted

LAN cable shall be evenly distributed in the right and left equipment rack cable ducts or on cable

tie bars based on the equipment termination location and/or supplier documentation to minimize

cable congestion.

7.7.2. DS1 Cable

DS1 cable, also referred to as Shielded Twisted Pair – (STP) cable shall be evenly distributed and

separated into transmit and receive groups wherever possible. Transmit cables should be routed

up one side of the equipment rack and receive cables routed up the other side of the rack based on

the equipment termination location and/or supplier documentation to minimize Near End

Crosstalk – (NEXT).

7.7.3. Coaxial Cable

Although Near End Crosstalk – (NEXT) is not a concern for DS3 circuits due to individual

conductor shielding, separate coax cables including separate multi-conductor coax cables for

transmit and receive shall be maintained wherever possible for ease of installation and

maintenance.

Combining transmit and receive within the same multi-conductor coax cable shall be limited to

applications where the appropriate cable is not available through CR inventory.

Example applications:

Three (3) DS3’s Six (6) conductor 73406 or 73506 is acceptable

Six (6) DS3’s Twelve (12) conductor 73512 is acceptable

Twelve (12) DS3’s Twenty-four (24) conductor 73524 is acceptable

7.8. Power and Grounding Cable

Power cable shall be run in dedicated cable trays. All Grounding cables shall be run on separate

cable ladder sidebar supports and NEVER run intermingled with other office cables.



It is preferred that each Equipment Rack or Frame have a dedicated Fuse Panel/Circuit Breaker

Panel for powering equipment loads. With Managers approval equipment installed in relay racks

immediately adjoining the relay rack that has the fuse panel may be powered from that fuse panel.

7.8.1. Cabling Requirements

8. BONDING AND GROUNDING (SEE GROUNDING STANDARDS THAT APPLY TO THE JOB)

This section covers installation requirements for Contractor-installed bonding and grounding

elements in Windstream facilities.

The Contractor is responsible for maintaining the integrity of the grounding systems and for

providing the necessary tools and miscellaneous supplies to complete the grounding system per

the construction documents.

8.1. Inside Plant Grounding Systems

Grounding systems are described in WSP-3263 (Inside Plant Grounding and Bonding Standard)

and additional information is listed below.

The Grounding elements in a Windstream facility are identified as follows:

• Master System Ground Bar (MSGB) located in the central office near the primary

grounding electrode.

• Cable Entrance Ground Bars (CEGB) usually located inside the building near the cable

entry point.

• Floor Ground Bars (FGB), located at a central point in the office to be convenient to

connect to central office equipment bays.

• Isolated Ground Bars (IGB), located near switches and other equipment that require

electrical and mechanical isolation from other equipment.

• Non-isolated Ground Bars (NGB), located centrally to equipment not required to be

isolated.

The wire size used to interconnect these ground bars will be determined by Windstream in accord

with the Inside Plant Ground Bond standard currently under development. All grounding cables

must be labeled as defined by Windstream labeling standards (see WSP-3039; Equipment and

Cable Labeling Standards) and shall be clearly marked “Grounding Cable. Do Not Remove”.

Ground wires shall not be run in cable troughs; they must be installed on cable support brackets

hanging below the cable tray. Vertical runs shall be supported to the side of the cable tray with

waxed lacing cord at 8 to 12 inch intervals. AC conduits or raceways shall not be used to support

grounding conductors.

Ground conductor mounting hardware shall not completely encircle the conductor.

Nylon tie wraps shall not be used to secure ground conductors.

8.2. Grounding Bays, Frames and Line-ups

Each lineup requires an aisle ground feeder. The rear aisle feeder shall connect to the main aisle

feeder or to the central office ground bar. The main aisle feeder shall connect to the Central

Office Master Ground Bar or the Floor Ground Bar.

Each frame or equipment bay requires a #6 AWG to the aisle feeder. A two hole-#6 compression

connector shall be used for the frame ground connection. Paint must be removed from the contact

surface area that can be verified after the connector is in place. A thin coat of No-Ox-Id or

Penetrox E grease must be applied to the contact surface.

allow access for maintenance.

11.4. Installation

When possible, slack in OSP cables shall be stored in the cable vault so that cable may be pulled

back and re-terminated or spliced.

When slack in fiber optic cable is required, slack shall be stored in a fire retardant box of

sufficient size to prevent damage from excessive bending radii.

11.5. Jumpers

• Fiber optic jumpers shall have a minimum-bending radius of 2 inches. Fiber jumpers

shall not make any sharp bends, cross over metal edges.

• Fiber optic jumpers shall be placed in the Fiber Guide without restraint. Jumpers shall not

be laced or tie-wrapped at any point in its run.

• Fiber optic jumpers that need to be secured outside of the fiber protection will be secured

with Velcro ties.

• Fiber optic warning labels, usually provided by equipment manufacturers, shall be placed

on fiber trough runs.

• When running fiber in a Windstream site, it is important to maintain good fiber

management in order to increase system reliability and reduce human error. While

working with fiber can at times be tedious, extreme care should always be taken when

fiber is involved.

• Never look into the end of a fiber. Typical wavelengths are not in the visible light

spectrum. The intensity of the beam from many of the amplifiers and transmitters is

Inside Plant Installation and Construction Standards WSP-3262 Version 1.3 - 02/01/2013 Fiber Cables


enough to damage the retina of the eye. Since it is often difficult to be sure whether a

fiber is connected to a transmitter or not, it is best to be safe and use a meter to determine

if light is present.

• Fiber cable should not be exposed. Fiber should be run in yellow or orange fiber guide

duct management system. Spit duct may be used at downspout drop locations to optical

equipment bays. Where fiber MUST be exposed (i.e. where the fiber terminates on the

equipment), it should be done in a manner that protects the fiber as much as possible.

• All fiber should be cleaned per WSP 6009 (Fiber Cleaning Standard).

• All Fiber storage should be done at the FDP slack storage. Slack storage should NEVER

be done on the equipment end. If the fiber lengths exceed the amount of storage available

in the slack storage at the FDP, new jumpers should be ordered.

• A minimum bend radius of 4" should be maintained at all times in order to avoid

attenuation of the fiber. Conduit and fiber duct sweeps should be engineered to meet the

4" bend radius at all times.

• Attenuators should be fixed in-line attenuators and applied at the FDP or network

equipment only. Variable attenuators (VOA) are acceptable in the Windstream network

in existing networks that currently have VOA deployed. All new network deployments

must have managers or higher approval before deployment of VOA and the VOA

manufactory and type must be approved by the Windstream engineer.

The requirements for splicing and handling Fiber Optic Cable can be found in WSP-3018 (Fiber

Splicing Standards).

The fiber optic jumper standards can be found in WSP-3204

Inside Plant Installation and Construction Standards WSP-3262 Version 1.3 - 02/01/2013 Equipment Removal


12. EQUIPMENT REMOVAL

This section covers the procedures to be followed when mining cable or when equipped circuits,

apparatus, frames, bays, units or batteries are removed or made spare.

When removing shelves or equipment bays, cable, etc., it is the responsibility of the Contractor to

maintain the integrity of the central office grounding system.

The Contractor shall ensure that all equipment added, rearranged, modified or removed is in

conformance with the installation agreement and Windstream standards.

A MOP may be required prior to the start of a removal project.

12.1. Removing DC Power Connections

When removals include disconnecting power from a MPD or BDCBB or BDFB (Main Power

Distribution, Battery Distribution Circuit Breaker Bay, or Battery Distribution Fuse Bay), fuse

panel or circuit breaker panel, the Contractor shall:

• Coordinate removal activities with Windstream. Power work on a live system will require

a maintenance window in addition to the MOP. No work on a live system should be done

outside the maintenance window.

• Before powering down any equipment, verify that all traffic has been groomed from the

system. When removing power from a bay, it is imperative to verify the breaker or fuse

positions to be turned off. Once every effort has been made to verify the fuse/breaker

locations, turn off the “B” side first and verify that the correct circuit has been turned off.

Repeat the procedure for the “A” side. Remove fuse designation information from the

panel.

• Verify that no voltage is present on the battery or battery return conductor. If the cable is

to be mined out later, insulate the exposed ends and ensure that the cables are labeled

with its termination point. Remove any breaker associated with the cable.

• Change drawings and documentation as necessary.

12.2. Removing Equipment from Bays

Before removing any bays or equipment, the contractor should verify that the equipment or rack

has been powered down. Additionally, the contractor must ensure that the equipment is not longer

service effecting and that its removal will not cause customer circuit interruption. Any cables that

are to be mined out at a later date should be labeled with termination points and the ends

sufficiently insulated.

• A MOP must be created and followed for all equipment removals in a Windstream site.

Always double check removal assignments to ensure that the correct piece of equipment

is being removed.

• The Contractor shall tag all equipment removed from the bay by equipment name,

number of the bay equipment was removed from and disposition of equipment as directed

by Windstream.

• Equipment shelves to be reused shall be prepared by removing wire connections and

labels denoting its previous use. Far end termination and identification labels shall also be

removed.

• When removing frames and bays from under auxiliary framing, pipe stanchions must

support the framing approximately at 5-foot intervals

Inside Plant Installation and Construction Standards WSP-3262 Version 1.3 - 02/01/2013 Equipment Removal


12.3. Cable Mining

When it is determined that power cable and other cable types as outlined in section 7.6.1 are not

to be reused, the abandoned cables shall be removed per the approved statement of work.

• Cable mining requires a MOP prior to cable removal activities.

• A cable is considered dead when both ends have been disconnected and cut at the top of

the removed bay.

• Cable mining operations shall be conducted from ladders or platforms so the removal

area is visible.

• Cable shall be removed in short runs of no more than 4 feet lengths to prevent rubbing or

abrasive damage to the insulating jackets of other cables by pulling long sections of cable

from the stack.

• No cable shall be cut unless one end of the cable is clearly visible and verification is

assured. Preferred method of verification is to hold an open end of the cable in one hand

while the cut is made. No cable shall be cut in the middle. Only cable cutters equipped

with a Ring guard are to be used.

• After cable mining is complete, the cable run must be restored. The remaining cable shall

be inspected for damage. Any tears or abrasions to any cable must be repaired and re-

laced.
