PROJECT BASIC ELEMENTS

Installation

Install or utilize existing adequately sized and routed cable support pathway “systems”

throughout the ceiling areas wherever necessary to support new cabling.

Install and terminate the new cabling onto the appropriate jacks at the end location and on

the appropriate patch panels in the appropriate IDF/Data Center.

Wiring termination scheme for all CAT6 is 568-B.

Labeling

Utilize the labeling system that complies with TIA 606-A standards and the City’s needs. The

City using a specific labeling method (see page 5).

Testing

Test and certify each cable drop per the TIA 568 B-2 testing standards for Category 6 cabling.

Provide the City with hardcopy test results in a 3-ring binder and thumb drive.

Certification

Coordinate manufacturer certification and provide the City of Torrance CIT Dept. with

manufacturer certification/warranty documentation (if required by contract).

Warranty

Provide minimum one year labor and workmanship warranty.

Materials Used

The City requests CommScope brand cable and CommScope brand connectors, faceplates,

and patch panels, on this project. Any substitutions not mentioned in this document must be

approved by City of Torrance Telecom.

Cables must be continuous in length, contain no splices, kinks or damage and cannot exceed

90 meters in length between workstation jacks and patch panel. No ty-wraps. Velcro only.

All interior cables will be Plenum-rated (CMP) Cables that run into a Data Center must be

100% Plenum even if in conduit.

Station Data Cable, WIFI devices, and TV/Monitor/Projector network connections for this

project will be CAT6 green jacket color.

Station RJ-45 Data locations will be terminated on rack mounted patch panels at IDF/Data

Room. Contact City of Torrance CIT Dept. for rack location approval.

Station Voice Cable for this project will be white jacket color.

All Voice Cables will be terminated on a Siemon 66 punch down block mounted on an IDF

backboard using standoff mounting blocks. Contact City of Torrance CIT Dept. for backboard

location approval.

Security Camera CAT6 Cables will be yellow jacket color. These will be terminated on a

separate patch panel below station cabling. Contact City of Torrance CIT Dept. for rack

location approval.

PA System CAT6 cabling will be grey jacket color. These will be terminated on a separate

patch panel below station cabling. Contact City of Torrance CIT Dept. for rack location

approval

Patch panels will be either 24 or 48-port.

All Data jacks terminated in 6 port faceplates will be green. Voice Jacks will be white.

One cable is to be split for 2 RJ11 jacks per faceplate. W/BL only would be first jack. W/GR

only would be second jack. Wrap the remaining two pairs around the sheath.

Faceplates, surface boxes, furniture outlets, etc. will be white in color.

5 | P a g e

Any and all penetrations in walls or ceilings must be sleeved. Sleeves must meet minimum

fire standards where they are installed in fire walls or barriers.

Terminated CAT6 cabling must be terminated in numerical sequence on the patch panels

starting at 001 continuing on to end of patch panel. Each type of device/cable color will be

terminated on its own patch panels with its own numbering. Example: Station and Wi-Fi :

Green 1- 144, Security Cameras : Yellow 1-48, Etc. It is not necessary to have the cable

numbers in the work areas in sequential order unless the contractor wishes to do so.

The labeling scheme will be the Transit Center (TC), the Floor (1), the floor telephone room (1)

and the cable number 001 through 144. Therefore at the faceplate you would put the closet

number at the top, (example: TC 1.1) then the top two voice cables would share a number

taken from the 66 block location (example: V-1) and the data jacks at bottom of the faceplate

would show their positions on the patch panel and be marked below each jack. (Example: D-

1 and D-2).

Voice cabling will be used at all locations with a phone only or combined phone/data

faceplates. The numbering will be sequential 1, 2, 3 etc. on each 66 block. (Example the first

4 pair cable would be 1, the second four pair cable would be 2, etc.)

All Cables must be labeled appropriately in four (4) places:

1) At the Work station jack visible to technicians and other staff looking at the jack. This

label should be a machine-generated label such as a P-Touch label or Rhino label and be

affixed to the jack below the RJ-45 port.

2) At the Work station jack, on the cable sheath 2 inches before where the cable sheath

is stripped away. This label may either be a machine-generated label such as a P-Touch label

or be made with a Sharpie Fine-Point permanent marker. This label will only be visible when

the jack is disassembled.

3) At the front of the patch panel, on the patch-panel port covering the originally

stenciled numbers (whether above or below), where it is easily visible to personnel. This label

should be a machine-generated label such as a P-Touch label or Rhino label.

4) At the rear of the patch panel on the cable sheath approx. 6 inches or so before the

cable sheath is stripped away and the cable is terminated. This label may either be a

machine-generated label or be made with a Sharpie Fine-Point permanent marker.

Applicable Standards

The following industry standards are the basis for the structured cabling system

described in this document. The list is incorporated by this reference to them.

TIA/EIA-568-C (Commercial Building Telecommunications Cabling Standard)

TIA/EIA-569-A (Commercial Building Standard for Telecom, Pathways and Spaces)

TIA/EIA-606 (Administration Standard for the Telecommunications, Infrastructure of

Commercial Buildings)

TIA/EIA-607 (Commercial Building Grounding/Bonding Requirements)

1.2.2. NFPA

NFPA-70 (National Electric Code (NEC) -1999)

ISO/IEC 11801 (Generic Cabling for Customer Premises)

1.2.4 IEEE 802.3an (Physical Layer and Management Parameters for 10 Gb/s Operation, Type

10GBASE-T)

The most recent versions of all documents apply to this project.

If there is a conflict between applicable documents, the order above shall dictate the

order of precedence in resolving the issue unless an enforceable local or national

code is in effect.

PATHWAYS

ANSI/TIA reference 569-B

As part of this project, the Contractor is required to plan out and establish a TIA-569-B

compliant pathway and support “system” to properly accommodate new cabling. The

Contractor shall work closely with the General Contractor’s representative to establish this

pathway system to make sure it meets the needs of the City both now and in the future.

These new pathways must be properly routed through the ceiling areas and fastened to the

building structure in ways that do not violate the TIA building standards, the NFPA 70 NEC

and any other industry “standard” or practice.

ON-SITE SUPERVISOR/PROJECT COORDINATOR

The City requires that a Project Coordinator or Lead-person be assigned to this project and be

present the entire time work is going on. This person must have experience in the installation

and maintenance of a commercial high performance cabling system. They must also be

familiar with the TIA cabling standards, the NFPA 70 National Electrical code, BICSI standards

and practices and general building and construction knowledge and standards.

BICSI RCDD STAFF REQUIREMENT

The Contractor must have at least one full-time permanent employee on staff that is BICSI

RCDD certified and is available to the On-Site Supervisor/Lead Person running this project.

This person must be available for consultation should any issue arise.

EXTRA CABLING IN ACCESIBLE CEILING AREAS

The Contractor is to provide 4- Cat6 Data and 2- Voice cables, labeled, with approx. 20’ of

slack (neatly coiled in the ceiling and secured with Velcro) on each floor of both buildings.

These are to be pulled from the nearest IDF/Data Center to the farthest “accessible” ceiling

location near occupied spaces. These cables are to be numbered and properly terminated on

the Patch Panel (Cat6) or 66 block. They do not need to be jacked or certified.
