3.05 INSTALLATION OF CABLING

A. Comply with NECA 1.

B. General Requirements for Cabling:

1. Comply with TIA-568 (SET).

2. Comply with BICSI ITSIM, Ch. 6, "Cable Termination Practices."

3. Install 110-style IDC termination hardware unless otherwise indicated.

4. Terminate conductors; no cable shall contain unterminated elements. Make terminations only at indicated outlets, terminals, cross-connects, and patch panels.

5. Cables may not be spliced. Secure and support cables not more than 6 inches from cabinets, boxes, fittings, outlets, racks, frames, and terminals. Do not over-cinch or crush cables.

6. Install lacing bars to restrain cables, to prevent straining connections, and to prevent bending cables to smaller radii than minimums recommended by manufacturer.

7. Bundle, lace, and train conductors to terminal points without exceeding manufacturer's limitations on bending radii, but not less than 4X cable diameter. Install lacing bars and distribution spools.

8. Hook and loop (Velcro)-style cable ties shall be used to bundle and secure exposed cables in the concentrator enclosures and MDF/IDF rooms. Use of plastic cable ties is not permitted.

9. Do not install bruised, kinked, scored, deformed, or abraded cable. Do not splice cable between termination, tap, or junction points. Remove and discard cable if damaged during installation and replace it with new cable.

10. Cold-Weather Installation: Bring cable to room temperature before de-reeling. Heat lamps shall not be used for heating.

11. Pulling Cable: Comply with BICSI ITSIM, Ch. 4, "Pulling Cable." Monitor cable pull tensions, and do not exceed manufacturer’s recommended cable pull tension.

a. When installing in conduit, use only lubricant approved by cable manufacturer and do not chafe or damage outer jacket.

12. Service Loops: Provide the following minimum extra length of cable, dressed and routed neatly:

a. At MDF/IDF frames: 60 inches, neatly installed in vertical wire manager or accommodated by additional routing around overhead ladder rack runway.

b. At Concentrator Enclosures - Terminated Cables: 24 inches, neatly looped inside housing

c. At Concentrator Enclosures - Pass-through Cabling: 24 inches, neatly installed inside housing for horizontal UTP cables that pass through enclosure.

d. At Surface Raceway Outlets - Copper: 12 inches, neatly installed in surface raceway channel.

C. UTP Cable Installation:

1. Comply with TIA-568-C.2.

2. Maintain pair twists as close as possible to point of termination, but do not untwist UTP cables more than 1/8 (.125) inch from the point of termination to maintain cable geometry.

3. Concentrator Enclosures: No cabling is to be routed down through the center area of the enclosure so as to inhibit the installation of network electronics.

4. MDF/IDF: Install and route cabling on overhead ladder rack runway and within horizontal and vertical cable guides to terminating hardware.

D. Group connecting hardware for cables into separate logical fields.

E. Separation from EMI Sources: Comply with requirements of Section 27 05 03 -

Communications General Requirements.

A. Comply with requirements in Section 07 84 00 - Firestopping.

B. Comply with TIA-569-D, Annex A, "Firestopping."

C. Comply with BICSI TDMM, "Firestopping Systems" Article.

3.07 GROUNDING

A. Install grounding according to BICSI TDMM, "Grounding, Bonding, and Electrical Protection"

Chapter.

B. Comply with TIA-607-C.

3.08 IDENTIFICATION

A. Comply with requirements in Section 27 05 53 - Identification for Communication Systems.

3.09 CLEANING

A. Comply with requirements of Division 27 05 03 - Communications General Requirements for cleaning.
