CHAPTER 1 INTRODUCTION

1. About This Manual

a. This manual contains the policies and procedures for architects, contractors, and telecommunications design professionals who are involved in telecommunications projects on the UC Davis campus. The manual should be used as a guide for projects providing telecommunications cabling, to include Outside Plant Cable, Wireless Radio and Network Systems. Work may include new or renovated buildings and may consist of upgrading or adding cabling infrastructures, cable and network electronics equipment. b. This manual assumes that the user is familiar with telecommunications distribution systems, the cable and hardware used in them, the cabling pathways and support structures and the installation of cabling and wireless radio and network systems in buildings and campus environments. It is not intended to be a training manual in telecommunication distribution systems or to replace existing industry standards. c. Terminology used throughout this document to identify building termination locations is unique only to the UC Davis campus. Terms such as Area Distribution Frame (ADF), Building Distribution Frame (BDF) and Intermediate Distribution Frame (IDF) are used in lieu of Industry Standard terms, such as Horizontal Cross-Connect (HC) and Intermediate Cross-Connect (IC). The requirements for these locations still adhered to the American National Standards Institute (ANSI), Telecommunications Industry Association (TIA) and Electronic Industries Alliance (EIA) standards. d. Request for waivers or clarification of specific design issues must be forwarded to the Manager System Engineering & Design, UC Davis Communications Resources.

2. Communications Resources’ Responsibilities for Projects

a. Communications Resources is responsible for UC Davis’ inside and outside telecommunications system facilities, and network connectivity and the associated backbone equipment. Communications Resources’ responsibilities are outlined in the UC Davis Policy and Procedure Manual, Section 310-10 found in Appendix D of this document. b. These responsibilities include the review of all new telecommunications project plans, and require the following review items:

1) Communications Resources shall be provided copies of the Project Planning Guide (PPG), Capital Improvement Budget (CIB), Detailed Project Program (DPP), Design Guide or other such documents describing the University approved program. 1These documents shall be provided to Communications Resources upon approval of the governing agency, responsible for managing that project.

4) Communications Resources shall be provided Construction Documents (CD) for review at each stage of the Construction Document process, and provided a minimum of ten workdays from date documents are received by CR for review and return of comments.

c. When a new building or building renovation is planned, architectural drawings are typically released for review by Communications Resources in the following order:

1) Schematic – These are the initial planning documents and design drawings which assist departments in the early stage of the project. The Schematic Design documents shall consist of System Narrative, including Area Distribution Frame (ADF), Building Distribution Frame (BDF) and Intermediate Distribution Frame (IDF) information, and campus connection points. Drawings should include title Sheet, single line diagrams, site plan (may be part of electrical site plan). 2) Design Development—As the architectural design process progresses, overlays are developed to show the various structures and systems planned for the building. Design Development documents shall consist of outline specifications, in the CSI model. Drawings should include title Sheet, single line diagram site plan, enlarged floor plans of ADF, BDF, IDF and Details. 3) Construction Documents—These documents depict the final design before bid submittal is undertaken. The Construction Documents shall consist of a completed Cabling Specifications and Drawing set. 4) Working Copy—This is the Bid Copy. 5) “Record Document” Drawings – These drawings and documents represent the project as it is finally constructed and are deliverable prior to final inspection of the project.

Note: Communications Resources comments and requests must be incorporated into the reviewed documents in full for the next review of documents, or an explanation must be provided to Communications Resources, regarding the status of comments and requests. Communications Resources will postpone further reviews until all comments and requests have been addressed or incorporated into current documents and drawing.

d. Architects, contractors, and telecommunications design professionals must indicate, on the design drawings, and in the design specifications, the location and specification of the physical infrastructure required for a complete telecommunications cabling pathway and distribution system, as well as, the date and revision number of the CR Telecommunications Standards document used at the time of this design. This physical infrastructure shall include:

1) Network Access Module (NAM). Reference Chapter 2 for a complete description of a NAM.

2) Cabling and wiring for a complete telecommunications system.

3) The infrastructure necessary to support the horizontal, riser and campus cable plants. 4) The ADF, BDF and IDF locations.

3. The Telecommunications Distribution System Design Process

a. The UC Davis telecommunications distribution design system is divided into five segments:

1) The Horizontal Segment, Chapter 2, consists of the NAM’s, cabling to the IDF, and the associated pathways. 2) The Equipment and Telecommunications Room, Chapter 3, is the space that houses the ADF, BDF and IDF. 3) The ADF, BDF and IDF, Chapter 4, contain the hardware for terminating the horizontal cable from the NAM, along with riser and campus cables. The BDF and IDF is the room that can also house common equipment, such as switches and hubs. 4) The Riser Segment, Chapter 5, refers to the riser cable, and the sleeves, slots, and conduits that enable the cable to pass from floor to floor, BDF to IDF and IDF to IDF. 5) The Campus Segment, Chapter 6, refers to the cabling and infrastructure that interconnect buildings or systems on a campus.

b. The network electronic equipment, to include design, engineering and installation, is typically accomplished by Communications Resources.

4. Overview of this Manual

a. This manual is divided into nine chapters with each chapter divided into three or more paragraphs. Chapter 1 is an overview of this manual, and the responsibilities of the Communications Resources office. b. Chapters 2 through 9 describe in detail the seven segments of the telecommunications distribution system. These sections describe “The Design Process”, the main topics and components that must be considered when planning and designing a particular segment of the system. c. This manual also includes the following appendices:

1) Appendix A - Specifications contain detailed technical specifications. 2) Appendix B - References contain a list and brief description of the industry standards and guidelines for telecommunications systems and how to obtain a copy of them. 3) Appendix C - Glossary contains the definition of terms used in telecommunications design, engineering, construction, and provisioning. 4) Appendix D - UC Davis Policy and Procedure Manual, Section 310-10.



CHAPTER 2 THE HORIZONTAL SEGMENT

1. The Design Process

a. The horizontal segment consists of two elements:

1) The horizontal cable and connecting hardware that provide the means for transporting the telecommunications signals between the Network Access Module (NAM) in the work area and the Intermediate Distribution Frame (IDF).

2) The horizontal cabling pathways and spaces that distribute and support the horizontal cable and connecting hardware between the NAM and the IDF.

Note: Cables that interconnect in IDF’s on the same floor, while physically horizontal in orientation, are considered part of the riser segment.

b. This section describes the policies and procedures for the following design activities:

1) Determining the type and number of NAM’s in the work area.

2) Identifying the types and lengths of cable used in the horizontal segment.

3) Determining termination hardware requirements at the NAM.

4) Designing the structures needed to support the horizontal cabling.

5) Assigning the NAM numbers to the appropriate locations

. 6) Cable testing procedures.

2. The Type and Number of NAM’s

a. Network Access Modules (NAM) at UC Davis fall into three general configurations: Basic, Enhanced, and Integrated. b. The basic design supports voice or data applications. It consists of a single NAM module supported by one 4-pair UTP Category 5e cable. A basic outlet may be used for a wall phone, a courtesy phone, a card reader, or to augment an existing work area with additional voice or data capacity. c. The enhanced design supports voice and data applications. It consists of two NAM modules per outlet supported by two 4-pair UTP Category 5e cables. Each 4-pair UTP Category 5e cable supports one NAM module only. The enhanced outlet is the most commonly used configuration at UC Davis. d. The integrated design supports complex systems including voice, data, and video applications. In general, it consists of three or more 4-pair UTP Category 5e cables supporting three or more NAM modules per outlet. Each 4-pair UTP Category 5e cable supports one NAM module only. It may also consist of a combination of 4-pair UTP Category 5e cables with a 4-strand indoor fiber optic cable (Multimode and/or Singlemode). A fiber optic supported NAM will consist of a surface mounted interface box that will allow for proper fiber bend radius, with LC type connectors. Reference Specification 01 for additional information. e. The features of these three designs may be combined in the most cost-effective manner with Communications Resources’ approval.



f. A minimum of two enhanced NAM’s must be provided in each office and conference room. g. At least one basic NAM must be provided in each conference room for a wall-mounted telephone. Location of NAM shall be near an exit door, and meet ADA requirements for access.

h. Laboratories require additional NAM’s to support workstations and test equipment. Wall-mounted telephones shall not be installed over laboratory countertops.

i. Large classrooms shall use a wireless network for their data access. Contact Communications Resources for the latest design standard for this area.

j. A 4 × 4 × 2 1/8 inch electrical back box with a single gang plaster ring must be used at each work area for NAM installations. From each back box a minimum of ¾” EMT conduit for basic and enhanced NAM, minimum 1” for integrated NAM’s, will be installed to the cable pathway support system. Conduit is to be sized appropriately for the fill of cable it is to accommodate. Reference Specification 06 for additional information.

k. Height and location of NAM and electrical back box for ADA accessible wall-mounted telephones and voice/data outlets must take into consideration the height of the telephone set and faceplate to insure height and distance requirements are satisfied.

3. ADA Requirements

a. Installed wall, counter-top and weatherproof telephones, in addition to, emergency call boxes and NAM’s, shall meet the requirements of the Americans with Disabilities Act (ADA). This requirement is referenced in ANSI/TIA/EIA 568-B.1.

Note: Wall telephones shall not be installed above or over Laboratory countertops. A standard desktop telephone shall be installed in these unique locations, if required.

b. All campus ADA approved wall phones (with an ADA compliant handset), weatherproof telephones and emergency call boxes and towers shall be installed in accordance with ADA requirements. The following is a list of currently installed products: (Reference Figure 2-1).

Figure 2-1 ADA Compliant Telephone/Emergency Call Boxes

4. Cable Types and Lengths

a. UC Davis recognizes two types of cables for use in the horizontal segment: UTP (unshielded twisted pair) and Multimode/Singlemode fiber optic cable.

1) UTP cable will be 4-pair, 24 AWG, solid conductor cabling that meets ANSI/TIA/EIA 568-B.1 and B.2 cabling specifications for Category 5e cable, to include any/all Amendments and Bulletins, and must meet specified specifications and performance requirements. Reference Specification 03, Table 03-1 for cable specifications and performance. Performance testing shall be conducted at the component level by a UL certified testing laboratory, and include Active Live Channel Testing to insure manufacture and performance quality. LANmark-350 manufactured by Berk-Tek is the preferred and recommended manufacture. If substitutions are requested by the consultant/contractor, then demonstrated equivalency must be provided. Reference Berk-Tek’s web site for additional information. (http://www.berktek.com/) 2) Fiber optic cable will be a minimum of 4-strands, Multimode, 62.5/125mµ graded index, tight-buffered, indoor cable, or 4-strand, Singlemode, 8.3/125mµ, tight-buffered, indoor cable. Reference Specification 03, Table 03-2 for cable specifications. Corning Cable Systems MIC type cable is the preferred and recommended manufacture. If substitutions are requested by the consultant/contractor, then demonstrated equivalency must be provided. Reference Corning Cable Systems web site for additional information. (http://www.corning.com/cablesystems)

b. All conductive cabling and associated components must comply with Article 800 of the NEC (1999). Furthermore, all fiber optic cabling must comply with Article 770 of the NEC (1999), OFN-FT4 (Non-plenum) and OFN-FT6 (Plenum). c. All cabling will be UL Listed Type CMP, OFNR or OFNP if it is placed in air-handling plenums without conduit. The cable sheath will be marked with the UL listing. d. Horizontal UTP and fiber optic cables will not be spliced, nor with these cables contain manufacture splices.

http://www.corning.com/cablesystems



e. Horizontal cables will not be connected directly to telecommunications equipment. Suitable connecting hardware (i.e. patch panels and punch-down blocks) and factory-manufactured patch cords must be used to make the connection. Cross-connect jumper wire shall be used for voice and fire circuits only. f. Patch cords shall be manufactured by the same manufacture as the data patch panels and information modules, meet or exceed Category 5e requirements and specific performance requirements. Reference Specification 04, Table 04-1 for minimum performance specifications. Performance testing shall be conducted at the component level by a UL certified testing laboratory, and include Active Live Channel Testing to insure manufacture and performance quality. If substitutions are requested by the consultant/contractor, then demonstrated equivalency must be provided. Ortronics is the preferred and recommended manufacture. g. The maximum total length of horizontal cable IDF to NAM and patch cords (patch panel to equipment and NAM faceplate to workstation) shall not exceed 328 feet (100 meters). CR approved patch cord and jumper wire lengths are shown in Specification 04, Table 04-2. h. Cable slack must be provided at both ends of cable runs to accommodate future cabling system changes.

1) The minimum amount of slack shall be 1 foot for UTP cables and 3 feet for fiber optic cables at the outlet. In the IDF, UTP horizontal cables shall meet manufactures procedures for slack, patch panels, and 110 type blocks.

2) Service Loops placed during installation of 4-pair horizontal cable were tested and determined to cause Return Loss and NEXT problems on the order of 2-3dB. When creating service loops, they should be coiled in a Figure-Eight configuration to eliminate this effect. At UC Davis, service loops are not required for every installation, therefore, prior approval from CR must be obtained prior the installation of service loops.

3) The fiber optic cable must have a 10-foot service loop at the ADF/BDF/IDF location.

4) The slack must be included in all length calculations to ensure that the horizontal cable does not exceed 295 feet.

Note: These limits apply to all types of horizontal cables. In establishing these limits, a 33-foot allowance was made for the combined length of the manufactured patch cords used to connect equipment at the NAM and IDF locations.

9. Structures to Support the Horizontal Cabling

a. Special attention must be provided when selecting and designing the type and layout of structures to support the horizontal cabling. The design must accommodate cabling changes with a minimum of disruptions to building occupants.

Note: UC Davis requires that the space above the ceiling grid be used, whenever possible, to route the horizontal cabling.

b. Listed below are the steps needed to complete this phase of the design process:

1) Obtain an accurate set of floor plans.

2) Annotate, on the floor plan, the locations and types of NAM’s.

3) Annotate, on the floor plan, the locations of the equipment racks/cabinets located within the Equipment and Telecommunications Room for the ADF/BDF/IDF hardware. If these locations have not been identified, please reference Chapter 4 before proceeding with this section.

4) Verify that the distance from each NAM to the IDF does not exceed 295 feet. This distance must include the planned cable path as well as any vertical transitions.

Note: If there are horizontal cable lengths that exceed 295 feet, the IDF must be relocated to a more centralized location or another IDF must be added.

5) Sketch the route of the conduit and the cable tray on the floor plan.

Note: The preferred method of routing the horizontal cabling is to run conduit from the outlet to a cable tray placed along natural building corridors. The cable tray then channels the cabling to the IDF. See Specification 07 for conduit design considerations.

6) A ¾-inch EMT conduit must be used from basic and enhanced outlet boxes to the cable tray. A 1-inch, or larger, if appropriate, EMT conduit must also be used if the bulk of the cables to be supported exceed the recommended 40% fill ratio.

7) A 1-inch or larger EMT conduit must be used from an integrated design outlet to the cable tray. See Specifications 07 for details on horizontal conduit capacity. The following additional specifications also apply to the installation of conduit.

(a) Flexible EMT conduit is restricted to a 20-foot length, if required, in accordance with TIA/EIA 569-A. (b) All conduits will be shall be appropriately firestopped in accordance with TIA/EIA 569-A, Annex A, and any/all local fire codes.

(c) Conduit will be installed with a pull string with a minimum test rating of 200 pounds. (d) The ends of conduits will be reamed and bushed to eliminate sharp edges that can damage cables during installation or service.

8) Identify firewalls or fire rated barriers that will be breached during cable installation.


9) Conduit must extend through the fire rated barrier when a fire rated barrier exists between the outlet and cable tray.

Note: All horizontal pathways that penetrate fire rated barriers must be firestopped in accordance with TIA/EIA 569-A, Annex A and local fire codes. See Figure 2-2.

10) Identify hard ceiling or ceilings with restricted access that must be traversed during cable installation.

(a) Multiple metallic conduits will be used in these areas. (b) Conduits will be of a size that will ensure that a 40% fill ratio is not exceeded. (c) The ends of the conduit will be bonded and grounded. Conduit will be grounded to Main Terminal Grounding Busbar (MTGB). Refer to Figure 2-3. (d) Surface molding will be used to route cables from the work area outlet to the interstitial space in areas with limited ceiling access. Ortronics or Wiremold surface raceway is the preferred and recommended manufacture to insure compatibility with the Ortronics faceplates and modules. If substitutions are requested by the consultant/contractor, then demonstrated equivalency must be provided.

11) Identify NAM’s that will be located on walls that are not made of sheet rock construction such as plaster walls, concrete block walls, exterior walls, and insulated walls. Written approval must be obtained from the Manager, Systems Engineering & Design, Communications Resources to use surface mounted NAM’s if these walls cannot be fished. Ortronics or Wiremold surface raceway is the preferred and recommended manufacture to insure compatibility with the Ortronics faceplates and modules. If substitutions are requested by the consultant/contractor, then demonstrated equivalency must be provided.

Note: Exterior walls, while furred and covered with sheet rock, may not provide the necessary clearance between the sheet rock and the backing material (commonly concrete block) for standard NAM’s.

12) Identify the location of system furniture that will be cabled for communications. System furniture can be fed from furred columns, wire whips from abutting walls, or power poles or under-floor systems.

Note: The use of power poles will be minimized.

13) Minimum cable bend radii and conduit capacity must be considered when using a modular furniture system. 14) The minimum bend radius for 4-pair UTP cable, no load, is 4 times the outside diameter, or 1.0 inches. The minimum bend radius for horizontal fiber optic cable is 2.0 inches. 15) Refer to Specification 07 for details on conduit capacity. 16) The maximum pulling tension of 4-pair UTP cable shall be 25 lbs, and the maximum tensile load for horizontal fiber optic cable is 148 lbf . 17) Annotate on the floor plan the cable paths that will be supported with J-hooks or Adjustable Cable Supports (Hanger Bags). The type and size of J-hook or Hanger Bag will conform to the manufactures specification for size and number of cables, and the environment for which they are to be installed. This specification shall not be exceeded. 18) J-hooks and Hanger Bags will be spaced a maximum of every 4 feet to support the cable as referenced in TIA/EIA 569-A, and will be annotated on the construction drawings. 19) Velcro cable ties shall be used to secure cable bundles and patch cords, where required. Plastic Ty-Raps will only be used with prior CR approval, and then must meet installation requirements per TIA/EIA specifications.

10. Cable Testing Procedures

a. General

1) Test and report on each intermediate cabling segment separately, including Main Distribution Frame (MDF) to ADF/BDF/IDF, riser cabling, campus and horizontal distribution cabling (each segment, if multiple).

2) Test each end-to-end cable link.



b. Voice Cabling Plant. The Contractor shall perform tests on the voice telephone plant cable. The tests shall be performed end-to-end from each termination block on each pair. Provide computer-generated documentation of all test results on Contractor-provided, and University’s Representative-approved forms. This end-to-end test shall include the following:

1) DC Continuity 2) Reversals 3) Shorts 4) Opens 5) Overall loop resistance/cable length 6) Attenuation 7) Splits 8) Transpositions 9) Grounds

c. UTP Horizontal Cable Testing

1) UC Davis requires that all UTP cable pairs be Permanent Link tested with a Level IIE or Level III tester for full compliance with TIA/EIA 568-B.1 and B.2, Category 5e specifications regardless of intended use.

2) Test results must be provided for all conductor pairs of each cable, and meet Table 2-1 requirements.

3) The test results must be provided on a 3.5-inch MS-DOS formatted diskette in an MS Excel worksheet format.

4) Reference Table 2-1 for testing parameters.

d. Fiber Cable Testing (Horizontal and Campus/Riser/Backbone).

1) Field-testing instruments for multimode fiber optic cabling shall meet the requirements of ANSI/TIA/EIA-526-14-A. The light source shall meet the launch requirements of ANSI/TIA/EIA-455-50B, Method A. Reference TIA/EIA-568-B.3 for additional information. Per ANSI/TIA/EIA 526-14A, Annex B, Test Method B shall be accomplished.

2) Field-testing instruments for Singlemode fiber optic cabling shall meet the requirements of ANSI/TIA/EIA-526-7. Testing Method A and B shall be accomplished. Reference TIA/EIA-568-B.3 for additional information.

3) All fiber optic cables must be tested for link attenuation (i.e. power insertion loss, power meter test) as referenced in TIA/EIA-568-B.1, Section 11.3. See Table 2-2 for proper fiber testing measures. All strands will be tested in a bi-directional method with a Power Meter. Riser cables (installed and terminated within a building) shall be tested for link attenuation only. Outside plant cables shall be tested for link attenuation with both a power meter and an OTDR. Actual cable distance shall also be recorded and documented with the OTDR. . 4) All fiber optic cable, to include connectors, shall be tested in-line between two reference cables. One cable will be attached to the light source and the other to the power meter to measure the dB loss from both connectors, as well as any dB loss associated with the cable between the connectors.

5) The dB loss for a horizontal segment must not exceed 2.0dB. TIA/EIA 568-B.1 and 526-14A outlines the steps required to test multimode horizontal fiber optic cabling. TIA/EIA 526-7 outline the steps required to test Singlemode fiber optic cable. Horizontal multimode cable only needs to be tested at one wavelength (850 or 1300µm). Backbone cable (Campus, Riser, OSP) (multimode and Singlemode) shall be tested at both wavelengths (850 and 1300µm for multimode) and (1310µm and 1550µm for singlemode).

Note: Because of the relatively short cable lengths within the horizontal segment (less than 295 feet), the main loss will be connector loss.

6) Select two test jumpers. Ensure that the jumpers have a fiber core size of 62.5 µm (multimode) or 8.3µm (singlemode) and terminated with an LC style connector at the NAM and an LC- style connector at the IDF. 7) Ensure the optical source (light) meter is stabilized and has a center wavelength within ± 20 nm of the multi-mode nominal wavelength. The light source should be allowed to stabilize for approximately 5 minutes before testing begins. 8) Ensure the power meter and the light source are set to 850/1300 nm if testing multi-mode fiber or 1310/1550 nm if testing single mode fiber. 9) Ensure that all connectors are clean. 10) Establish a reference. A baseline must be established for the test jumper between the power meter and light source unit. 11) Verify the second test jumper by adding this second jumper between the power meter and the original jumper.



Note: If the loss is greater than 0.5 dB, clean all connectors (except the connector inserted at the source) and test again. If the loss is still unacceptable, replace the second test jumper.

12) Test the horizontal segment from one end of the fiber - from the distribution cabinet in the telecommunications room, horizontal or intermediate cross connect to the NAM. Place the light source at the distribution cabinet location and the power meter at the NAM location. The light source should not be disturbed once the testing begins.

13) The total signal loss for a fiber link will not be greater than 2.0 dB - this includes connector loss and fiber loss. 14) The installing contactor shall perform fiber optic testing on all installed fiber optic cabling. Test results and documentation, to include OTDR traces and Power Meter test results, shall be provided to the Communications Resources (CR) representative utilizing contractor-supplied and CR approved forms. Forms shall be submitted in a pre-agreed upon format (i.e. MS Excel spreadsheet, diskette, CD Rom, etc). The contractor shall submit these forms with all required information no later than five days after the cables are tested.

15) The contractor shall provide calibration certifications for testing equipment to be used. The contractor shall submit these certificates to CR, with all required information, prior to commencement of testing.

Note: Reversing the direction of test to see if the end connector is bad should isolate high loss, in a double-ended test.

Table 2-2 Basic Guideline for Loss Measurements

Basic Guideline for Loss Measurements for Installed Fiber Optic Cables Connector Loss: 0.75 dB per mated pair Splice Loss: (Fusion or Mechanical) 0.3 dB Fiber loss: Multimode 3.5 dB/km @ 850 nm

CHAPTER 4 THE ADF/BDF/IDF 1. The Design Process

a. The Area Distribution Frame (ADF), Building Distribution Frame (BDF) and Intermediate Distribution Frame (IDF) refer to the type of termination equipment located within an Equipment Room (ER) or Telecommunications Room (TR). Reference Chapter 3 for additional information on ER/TR requirements. b. The term ADF refers to a cross-connect point for fiber optic cable servicing a geographical area on the UC Davis campus, and outlaying areas. This cross connect hardware is physically located within an ER, TR or Controlled Environmental Facility (CEF), and can vary in size depending upon termination space requirements, (i.e. equipment cabinets and/or equipment racks). c. The term BDF refers to a cross-connect point for both copper and fiber optic cable serving a single or multiple buildings within an immediate area. This cross connect hardware is physically located within an ER or TR, and can vary in size depending upon termination space requirements, (i.e. equipment cabinets, equipment racks or backboard space). d. The term IDF refers to a termination point for horizontal copper and fiber optic cables within a single building and/or floor. This would apply to our horizontal cabling from the NAM to the 110 type cross-connect blocks for voice and RJ-45 patch panels for data, mounted within an equipment rack, cabinet or mounted onto a wall. This termination hardware is located within an ER or TR, and can vary in size depending upon termination space requirements. e. Although the ANSI/TIA/EIA 568-B.1 replaced the term IDF with the term Intermediate Cross-Connect (IC), on the UC Davis campus the terms ADF, BDF and IDF are used. f. It is important to note that an IDF can be collocated with an ADF/BDF. Additional space, racks, electrical and cable management are required to support these locations. g. The locations of the ADF/BDF/IDF’s must be submitted to the project manager for inclusion in the construction drawings, and they must be annotated on the floor plan.

6. Structures to Support Horizontally Offset IDF’s

a. IDF’s that are located in ER/TR’s that are not vertically aligned must be connected with cable trays, conduits and pull boxes. b. Cable trays that are used to support horizontal cabling may be used to support riser cables provided the following conditions are met:

1) The cable trays’ carrying capacity can accommodate the riser cables. 2) The route of the cable trays can be used or modified to accommodate the lateral run between the IDF and the NAM’s. 3) Refer to Specification 08 for cable tray specifications.

c. Conduit will be used to route the riser cables between the BDF/IDF located in the ER/TR if cable trays are not used to support the horizontal cabling. Conduit paths are tightly controlled pathways that must be coordinated with other trades during construction or remodeling.

1) The conduit will be rigid steel conduit (RSC), Electrical Metallic Tubing (EMT), or Intermediate Metallic Conduit (IMC), 4 inches in diameter.

2) The conduit will be grounded at each end.

3) The conduit will be installed with a pull string and the ends will be bushed to protect the cable.

4) Conduits that enter the ER/TR must be placed near the corner and as close as possible to the wall where the backboard is mounted to allow for proper cable racking and to minimize the cable route inside the ER/TR.

5) Conduit located in the ceiling must protrude into the ER/TR 1 to 2 inches and a minimum 7½ feet above the finished floor. Conduit will not turn down.

6) Reference Specification 07 for details on conduit fill for riser cables.

Note: A 1-inch conduit must be dedicated from the ER/TR to a sealed junction box on the roof of the building for use as an antenna access point. This conduit must be grounded using a path other than the telecommunications ground provided in the ER/TR.

7) Identify on the floor plans the BDF/IDF’s that will be supported using conduit. 8) Determine the number of conduits required. This number is the same as the number of sleeves required if the ER/TR’s had been vertically stacked. 9) Sketch the proposed route of the conduit on the floor plan.



d. Pull boxes

1) Determine if any pull boxes are needed along the conduit run. 2) Pull boxes are required in sections of conduit that are 100 feet or more in length or that contain more than two 90° bends.

Note any obstacles, existing cable facilities, or other underground utilities on the campus layout map. e. Note if right-of-way permits or easements are required. f. Review proposed cable route to determine if conditions exist that require environmental impact applications. Identify sources of future cable maintenance problems.



3. Cable Distribution Methods

a. Systems Engineering & Design, Communications Resources and appointed layout engineers must be contacted to determine the best cable distribution method along the proposed cable route. The method may be one or a combination of underground (in conduit), direct buried, directional boring, or aerial. b. An underground cable system consists of cables placed in buried conduits connected to maintenance holes (MH), hand holes (HH), and pull boxes (PB). Conduits are also installed from the building entrance location to poles, pedestals, MH’s and HH’s. Splices shall be located in maintenance holes only, when required. c. A direct buried cable system consists of cables and associated splices directly placed in the earth. The trench runs from the building entrance location to a pole, pedestal, MH or HH. This method is used only in cases where underground or aerial installations cannot be accomplished. d. An aerial cable system consists of cables installed on aerial supporting structures such as poles, sides of buildings, and other above ground structures.

Note: An underground cable system must be used if a conduit route is available between buildings.

4. Underground and Direct Buried Cable Requirements

a. The California Public Utilities Commission (CPUC) regulates underground and direct-buried cable placement specifications. All underground conduit and direct buried construction at UC Davis must conform to CPUC’s General Order Number 128, Section IV. b.

c. All cables entering a building must conform to the bonding and grounding requirements listed in the NEC, Articles 250, 770 and 800.

d. Warning tape containing metallic tracings must be placed a minimum of 12 inches above the underground conduit/duct structure and direct buried cable to minimize any chance of an accidental dig-up. The American Public Works Association has adopted the color orange for the telecommunications cables. Both ends of the metallic warning tape will be assessable from both ends after installation. Communications Resources must approve this assess ability prior to complete of conduit/duct and cable placement. e. Refer to Specification 13 for details on underground conduit requirements and conduit sizing. f. The minimum depth of a trench must allow 24 inches of cover from the top of the conduit/cable to final grade. Local underground utilities must be contacted, (48 hours prior to excavation or in accordance with statutes regulation utilities), a Underground Service Alert (USA) call number receipt (ticket) must be present and on site during any construction, and utilities located before digging to locate all subsurface facilities such as power, gas, water and outdoor lighting. g. Table 6-1 shows the vertical or horizontal separations that must be maintained between telecommunications facilities and other facilities sharing a common trench. h. See Figures 6-1 and 6-2 for typical trench cross-sections. i. Install a 12-14 AWG copper wire in any unused conduit structures not programmed for immediate fiber or copper cable installation, or where all dielectric fiber optic cable is installed singularly, for the purpose of tracing the conduit/cable route.

5. Cable Types

UC Davis recognizes two types of cable for outside use in the campus segment, copper telephone cable and fiber optic cable.

a. Outside Plant copper cable:

1) Filled core, (waterproofing compound) cable must be used for underground and direct buried cable installations. Filled cable preserves the integrity of the cable by providing physical protection against moisture penetration and seepage.

2) Direct buried cable requires an armored sheath to resist rodent and penetration type damage.

3) Plastic Insulated Cable (PIC) cables must be marked with cable length, cable code, date and manufacturer.

4) The following standard designations for copper exchange cable have been assigned by the Rural Utilities Services (RUS):

(a) PE-39 refers to filled cable with solid polyolefin insulation, and is suitable for both conduit and direct-buried applications. Cable must meet ANSI ICEA 7CFR-1755-039/390 specifications. (b) PE-89 refers to filled cable with formed polyolefin insulation for conduit and direct-buried applications. Cable must meet ANSI ICEA 7CFR-1755-089 and 890 specifications.

b. Outside Plant Fiber Optic cable:

1) Loose Tube, filled core, (waterproofing compound) cable must be used for underground and direct buried fiber optic cable installations. Filled cable preserves the integrity of the cable by providing physical protection against moisture penetration and seepage. Loose tube fiber optic cable is the preferred and recommended cable for Outside Plant applications at UC Davis.

2) Direct buried fiber optic cable requires an armored sheath to resist rodent and penetration type damage.

3) Reference Specification 05, Outside Plant Fiber Optic Cable Requirements, for cable specifications.

6. Maintenance Holes (MH) and Hand holes (HH).

a. MH’s or HH’s are required where maximum cable reel lengths are exceeded, at the intersection of main and branch conduit runs, and at other locations where access to the cable in a conduit system is required. Splices will not be located in HH’s or PB’s.

1) UC Davis has accepted the general sizing guidelines for MH’s and HH’s as used by PacBell. These guidelines or specifications are referred to as PTS, and are based on ultimate requirements.

2) MH’s and HH’s must meet the weight-bearing standards required under CPUC’s General Order Number 128.



3) MH’s, HH’s, and subsurface equipment enclosures in street areas, which are subject to vehicular traffic, must be constructed to withstand a minimum of H-20-44 highway loading as designated by the American Association of State Highway Officials. Floors of manholes must meet the requirements of Public Utilities Code, Section 8054.

4) Precast MH/HH’s must be used whenever possible. Site-cast MH/HH’s may be used when the size required exceeds precast sizes, obstructions prohibit placing precast MH/HH’s must be rebuilt, or a custom design is required.

5) MH’s must be sized to meet the maximum conduit requirements and be located to optimize the use of the associated conduit routes.

6) All conduits must be sealed in a MH/HH system to prevent water entry.

7) The strength of concrete used for MH’s must be at least 3,500 psi.

8) All hardware in maintenance holes will be galvanized. Maintenance holes must be equipped with:

(a) Bonding and grounding attachments and Uni-struts for racking. (b) Pulling eyes at least 7/8 inches in diameter, and at a minimum, be located opposite of each conduit entrance point. (c) A sump of at least 8 inches in diameter. (d) An entry ladder.

9) MH’s that are between 12 feet and 20 feet long must use two covers. MH’s over 20 feet long must use three covers. All MH covers must be marked for easy identification (T for telephone, S for signal, and TV for CCTV/CATV).

10) Conduit entry points:

(a) Located at opposite ends have the MH/HH, and preferably the main conduit formations should enter the end walls of the MH/HH at a point approximately halfway between the floor and roof. (b) For wall racking considerations, design splayed duct bank entrances at the end walls rather than center placement to ease in the racking of the cables and splices. (c) Conduit servicing buildings or other MH/HH’s will be installed using the subsidiary conduit method. (d) Lateral conduits entering MH/HH’s will be avoided. (e) If the total number of conduits being placed is significantly less than the capacity of the termination MH or cable entrance, conduit should enter at the lower level. The upper space should be reserved for future additions. (f) Conduits installed between MH/HH’s and Buildings, and between other MH/HH’s will be sloped per ANSI/TIA/EIA 758 to insure proper drainage of water.


(g) All conduits in buildings and MH/HH’s shall be plugged (firestopping material, duct seal) to prevent the entrance of water and gases.

11) Cores into existing MH’s can only be done via shop drawings clearly identify the methods and procedures to be used in the coring process. Shop drawings for coring into MH’s are to be submitted to Communications Resources for review and comment prior to commencement of work.

12) The maximum distance allowed between buildings and MH/HH’s and between MH/HH’s is 600 feet. The installation of plastic or fabric type innerduct within the conduit should be considered in locations that exceed this distance limitation.

13) No more than two 90º sweeps or bends will be allowed between buildings, MH/HH’s, and MH/HH to MH/HH’s. 45º conduit angles are preferred. Bends and sweeps will be concrete encased to prevent the pull rope from cutting through the conduit during the cable installation.

14) See Figure 6-3 for an example of a typical MH.

Figure 6-3 Maintenance Hole

CHAPTER 7 IN-BUILDING RADIO SYSTEMS

1. The Design Process.

a. This chapter establishes the policies and procedures regarding an in-building radio system required in new campus buildings.

b. This chapter also covers the needs assessment, specifications, type, cost evaluation, testing and acceptance of an in-building radio system.

2. General Radio Communications Coverage.

a. All buildings require the capability to support radio communications of the local public safety entities (Fire, Police etc.) b. This document provides guidance in support of the formal Radio System Coverage Evaluation / In-Building Radio Communication Systems that requires consideration of funding appropriations for specific radio system coverage of each newly constructed facility and/or consideration for existing facilities that may be impacted by the new construction. In many cases, a placeholder is to be used for in-building amplification costs, based on historical data, and a recommendation of $35,000 should be used for capital projects exceeding 5000 square feet or multi-level structures. Refine estimate during cost evaluation.

3. Definitions.

BTS – Base Transceiver Station also known as the donor site. DBm – dB, decibels, in milli-watts. A unit of measure for RF signal level. Distributive Antenna – A system of non-radiating cable connected to an array of passive antenna. Donor – Base Transceiver Station also known as the donor site. Donor channel – The frequency in which the donor site transmits digital control information Grade of Service – Typical service is stated as 95% coverage, 95% calls Received and Transmitted at Circuit Merit Level 3 (CM3). Reference Table 7-1, Circuit Merit Rating. Fiber Optic – Optical transport of radio signals over fiber optic cable. Off – Air Repeater – A repeater that receives frequencies from and antenna and amplifies and retransmits these frequencies. NPSPAC – National Public Safety planning and Advisory Committee FCC – Federal Communications Commission

4. General Policy

a. Except as otherwise provided, no person shall erect, construct, change the use of or provide an addition of more than 20% to, any building or structure or any part thereof, or cause the same to be done which fails to support adequate radio coverage for the clients of the University of California, Davis 800 MHz Trunked Communications System, (including, but not limited to, Firefighters, Police Officers or Emergency Response Personnel).

b. For purposed of this section, adequate radio coverage shall include all of the following:

1) A minimum signal strength of -95 dBm available in 95% of the area of each floor of the building or structure when transmitted from the campus Central Transceiver of the University of California, Davis 800 MHz Trunked Communications System. 6

6 When measuring the performance of a bi-directional amplifier, signal strength measurements are



2) A minimum signal strength of -95 dBm received at the campus Central Transceiver of the University of California, Davis 800 MHz Trunked Communications System when transmitted from 95% of the area of each floor of the building.

3) The frequency range which must be supported shall be 821-823 MHz and 866-868 MHz

4) A 100% reliability factor.

c. Amplification Systems Allowed. Buildings and structures which cannot support the required level of radio coverage shall be equipped with:

1) An internal multiple antenna system with or without FCC type accepted bi-directional 800 MHz amplifiers as needed.

2) Or radiating cable system (leaky coax).

3) If any part of the installed system or systems contains an electrically powered component, the system shall be capable of operating on an independent battery and/or generator system for a period of at least twelve (12) hours without external power input. The battery system shall automatically charge in the presence of an external power input. If used, bi-directional amplifiers shall include filters to reduce adjacent frequency interference at least 35 dB below the NPSPAC band. The filters shall be tuned to 825 MHz and to 870 MHz so that they will be 35 dB below the NPSPAC frequencies of 824 MHz and 869 MHz respectively. Other settings may be used if they don’t attenuate the NPSPAC frequencies and further if they are not more than one MHz from the NPSPAC frequencies.

d. Evaluation Process. The evaluation process for determining the need for in-building amplification is conducted in a minimum of three phases: Pre-construction, construction, and acceptance/implementation.

1) Pre-construction Phase. Before the construction of the new building, basic information can be gathered to begin the process of determining the need, type and actual implementation of augmentation to the radio system. In most cases, the following information must be known to properly design and cost estimate an in-building radio system.

(a) New Building Information.

(1) Type/Size of building – single story, multi-level, square foot (2) If multi-level, number of stories (3) Orientation of building – above/below ground, line of sight (4) Construction of the outer and inner walls. – Plaster, drywall, brick. (5) Proposed equipment locations – Equipment rooms, cableways, conduits. (6) Building location - Longitude and latitude coordinates.

based on one input signal adequate to obtain a maximum continuous operating output level.



(7) Local building code requirements and special requirements. (8) Building Blueprints or drawings.

(b) Existing System Information.

(1) BTS location – Longitude and latitude coordinates. (2) Donor channel frequency – Specific digital channel to enhance radio coverage. (3) Grade of Service required meeting objective. (4) Type of subscriber unit. (5) Number of channels and their frequencies. (6) Signal strength of donor site at the building location.

2) With the information above, the following steps can establish determining the potential need for an in-building radio system. 3) Needs Determination - Signal Strength Measurements. At the planned construction site, measure (or have measured) the signal strength of the donor control channel:

a) If the signal strength of the donor is –95 dBm or less on the outside of the building, the probability of additional in-building coverage is high. b) If the signal strength of the donor is greater than –95 dBm, determine the expected signal strength of the donor by subtracting the sum of the interior losses due to walls, doors and windows from the ambient signal outside the building. (See Table 7-2) c) If a signal strength of -95 dBm or greater is calculated at the inner most point of the building, an in building system may not be required. d) If the signal strength is calculated at –95 dBm or less, an in-building system is warranted. e) To determine signal strengths for specific areas on campus and evaluate the impact of the facility on existing structures, consult the latest UC Davis Outdoor RF Survey report. f) If determined that In-building amplification is required for either the proposed site or existing structures impacted by the proposed construction, provide a placeholder in the budget for cost of a communication system based on results of the above.

e. Construction Phase. As the construction progresses, refinements to the placeholder budget should be made to ensure adequate funds are available to cover the cost of providing in-building amplification to the new facility and to re-evaluate the impact on existing structures. Re-visiting the specifications from the initial evaluation will fine-tune the proposed cost line item. f. Acceptance / Implementation Phase. Using criteria from Section 7, the Project Manager will accept the In-Building amplification measurements, ensuring they are within design specification. The budget line item may be closed out upon final acceptance.



5. Cost Evaluation / RFSP

a. Once a determination has been made that in-building amplification is required for the proposed facility or as an augmentation to existing facilities impacted by the new facility, cost estimating an in building coverage system is mostly an academic process. The first step in this process is to determine if the system should be fiber based or an Off- air system. Each system has it own unique advantages and disadvantages. Table 2 identifies several cost considerations that may be quantified in the planning stage. b. Off – Air Repeater. If dark fiber is not present or too expensive to route to the building, in building coverage can be provided through the use of Bi-Directional Amplifiers and distributed antenna system or leaky feeder radiating cable. Off – Air Repeater systems are simple and reliable and typically cost less than fiber-based solutions. They are however, susceptible to interference caused by large level signals that are close to the pass band of the amplifier. Extra RF filtering can be engineered into the system design to reject the unwanted signals. Typical applications have a central head end amplifier, which drives the distributed antenna or leaky feeder cable and the remainder of the antenna system. Adding the cost of the amplifier installed plus the cost of the distributed cable system can determine a budgetary cost estimate of an Off-Air Repeater system. 3

6. Vendor Request a. Request for Survey and Proposal (RFSP) should be created to provide to multiple wireless system vendors. b. The format of the RFP can be mandated or left open to each vendor. However, the RFSP should at the minimum include the following sections:

1) Cover Letter stating overall system price 2) Company Capabilities 3) Statement of Work 4) System Description 5) System Block Diagram 6) General Schedule 7) Turnkey Pricing 4 8) Conditions of Quotation 9) Acceptance Test Plan (ATP) 10) Maintenance, Service and Warranty

3 NOTE: Radiating cable is typically used in narrow spaces such as tunnels and hallways. This is due the high coupling loss between the radiating cable and subscriber unit. As well, radiating cable has limited propagation and poor wall penetration characteristics. 4 Overall project management of the implementation of an in building coverage system should be offered and included in the turnkey proposal submitted.



11) The RFSP should clearly state the areas where coverage is needed, the grade of service expected (GOS), and construction schedule of the building in process. Additionally, the RFP should include the information gathered in the pre-construction assessment phase of this policy.

7. Testing and Acceptance

a. Once implemented, the RF coverage system should be tested via the pre-determined Acceptance Test Plan (ATP). b. The ATP should include personnel from Information and Educational Technology, Police, Fire, Safety and Vendor. A walk through test should be completed and any discrepancies noted and resolved by the vendor. c. When an in-building radio system is required, and upon completion of project installation, it will be the Project Manager’s responsibility to have the radio system tested to ensure that two-way coverage on each floor of the building are within General policy requirements as prescribed below: d. Each floor of the building shall be divided into a grid of approximately twenty (20) equal areas. e. The test shall be conducted using a Motorola MTS 2000, or equivalent, portable radio, talking through the campus Central Transceiver of the University of California, Davis 800 MHz Trunked Communications System. f. A spot located approximately in the center of a grid area will be selected for the test. g. The radio will be keyed to verify two-way communications to and from the outside of the building through the campus Central Transceiver. h. Once the spot has been selected, prospecting for a better spot within the grid area will not be permitted. i. Each grid area will be tested for transmission/reception, minimum signal strength of –95 dBm. If signal strength fails to meet the requirement, the grid area shall be marked as a fail. j. A maximum of two (2) nonadjacent areas will be allowed to fail the test. In the event that three (3) of the areas fail the test, in order to be more statistically accurate, the floor may be divided into forty (40) equal areas. k. In such event, a maximum of four (4) nonadjacent areas will be allowed to fail the test. l. After the forty (40) -area tests, if the system continues to fail, the project Manager shall have the system altered to meet the 95% coverage requirement.

m. The gain values of all amplifiers shall be measured and the test measurement results shall be kept on file with Communications Resources, a Division of Information and Educational Technology, so that the measurements can be verified each year during the annual tests. In the event that the measurement results became lost, the building owner will be required to rerun the acceptance test to reestablish, the gain values.



8. Additional System Testing

a. Communications Resources will periodically test in-building amplification systems. b. Results of the testing will be compared to designed specifications and corrective action taken if required maintaining the system within the desired design specification.

9. Qualifications of Testing Personnel a. Communications Resources shall be responsible for conducting or contracting system testing. All tests shall be conducted, documented and signed by a person in possession of a current FCC license, or a current technician certification issued by the Associated Public-Safety Communications Officials International (APCO) or the Personal Communications Industry Association (PCIA).

b. All test records shall be retained on the inspected premises and a copy submitted to Communications Resources and to the Police/Fire Department officials.

10. UC Davis Outdoor RF Survey Report a. At the discretion of Communications Resources, but no less than semi-annually, the campus shall conduct an Outdoor RF Survey mapping the campus footprint for RF energy. b. The report should specify specific frequencies, coverage with relative signal strength. Highlight those areas of signal strength below standards.

11. Annual Tests a. When an in-building radio system is installed, Communications Resources shall test all active components of the system, including but not limited to amplifiers, power supplies and backup batteries, a minimum of once every twelve (12) months. b. Amplifiers shall be tested to ensure that the gain is the same as it was upon initial installation and acceptance. Backup batteries and power supplies shall be tested under load for a period of one (1) hour to verify that, they will properly operate during an actual power outage. If within the one (1) hour test period, in the opinion of the testing technician, the battery exhibits symptoms of failure, the test shall be extended for additional one (1) hour periods until the /testing technician confirms the integrity of the battery. All other active components shall be checked to determine that they are operating within the manufacturer’s specifications for the intended purpose.

12. Five-Year Tests In addition to the annual test, Communications Resources shall perform a radio coverage test a minimum of once every five (5) years to ensure that the radio system continues to meet the requirements of the original acceptance test. The procedure set forth above shall apply to such tests.



13. Field Testing

a. Police and fire personnel, after providing reasonable notice to Communications Resources, shall have the right to enter property to conduct field-testing to be certain that the required level of radio coverage is present. b. Discrepancies from field-testing and recorded tests shall immediately be brought to the attention of Communications Resources. Communications Resources will provide corrective action in response to reported discrepancies.

Buffer tube colored stripes shall be inlaid in the tube by means of co-extrusion when required. The nominal stripe width shall be 1 mm.

h. For dual layer buffer tube construction cables, standard colors are used for tubes 1 through 12 and stripes are used to denote tubes 13 through 24. The color sequence applies to tubes containing fibers only, and shall begin with the first tube. If fillers are required, they shall be placed in the inner layer of the cable. The tube color sequence shall start from the inside layer and progress outward.

i. In buffer tubes containing multiple fibers, the colors shall be stable across the specified storage and operating temperature range and not subject to fading or smearing onto each other or into the gel filling material. Colors shall not cause fibers to stick together.

j. The buffer tubes shall be resistant to external forces and shall meet the buffer tube cold bend and shrink back requirements of 7 CFR 1755.900.

k. Fillers may be included in the cable core to lend symmetry to the cable cross-section where needed. Fillers shall be placed so that they do not interrupt the consecutive positioning of the buffer tubes. In dual layer cables, any fillers shall be placed in the inner layer. Fillers shall be nominally 3.0 mm in outer diameter.

l. The central anti-buckling member shall consist of a dielectric, glass reinforced plastic (GRP) rod. The purpose of the central member is to prevent buckling of the cable. The GRP rod shall be over coated with a black colored thermoplastic when required to achieve dimensional sizing to accommodate buffer tubes/fillers.

m. Each buffer tube shall be filled with a non-hygroscopic, non-nutritive to fungus, electrically non-conductive, homogenous gel. The gel shall be free from dirt and foreign matter. The gel shall be readily removable with conventional nontoxic solvents.


n. Buffer tubes shall be stranded around the dielectric central member using the reverse oscillation, or “S-Z”, stranding process. Water blocking yarn(s) shall be applied longitudinally along the central member during stranding. o. Two polyester yarn binders shall be applied contra helically with sufficient tension to secure each buffer tube layer to the dielectric central member without crushing the buffer tubes. The binders shall be non-hygroscopic, non-wicking and dielectric with low shrinkage.

p. For single layer cables, a water blocking tape shall be applied longitudinally around the outside of the stranded tubes/fillers. The tape shall be held in place by a single polyester binder yarn. The water blocking tape shall be non-nutritive to fungus, electrically non-conductive and homogenous. It shall also be free from dirt and foreign matter.

q. For dual layer cables, a second (outer) layer of buffer tubes shall be stranded over the original core to form a two-layer core. A water blocking tape shall be applied longitudinally over both the inner and outer layer with each being held in place with a single polyester binder yarn. The water blocking tape shall be non-nutritive to fungus, electrically non-conductive and homogenous. It shall also be free from dirt and foreign matter.

r. The cable shall contain at least one ripcord under the sheath for easy sheath removal of all-dielectric cable. The cable shall contain at least one ripcord under the inner sheath and under the steel armor for armored cable. The ripcord color shall be orange for non-armored sheaths and yellow for armored sheaths.

s. Dielectric yarns shall provide tensile strength.

t. The high tensile strength dielectric yarns shall be helically stranded evenly around the cable core.

u. All-dielectric cables (non-armored) shall be sheathed with medium density polyethylene (MDPE). The minimum nominal jacket thickness shall be 1.4 mm. Jacketing material shall be applied directly over the tensile strength members and water blocking tape.

All installed conduits shall be cleaned and verified with a flexible mandrel and a stiff brush. Mandrels shall be 12 inches in length, and sized to within ¼ inch of the inside diameter of the conduit. c. All conduits must be provided with a ¼ inch polypropylene pull rope or pull tape with a minimum of 200 pound pulling tension, in addition to, a 12-14 AWG copper wire in any unused conduit structures not programmed for immediate fiber or copper installations, or where all-dielectric fiber optic cable is installed singularly, for the purpose of locating and tracing the cable route. d. All unused entrance conduits must be capped/plugged and installed with pull strings. e. Conduit stubs entering the building must extend beyond the foundation landscaping. All conduit ends adjacent to the building must be flagged for easy identification. f. Conduit entering from a below grade point must extend 4 inches above the finished floor in the ER/TR. Conduit entering from ceiling height must terminate 4 inches below the finished ceiling. g. Conduit must be securely fastened to the building to withstand a typical placing operation performed by the service provider. The area around the conduit entrance must be free of any construction, storage, or mechanical apparatus. h. All metallic conduit and sleeves must be reamed, bushed, and capped when placed. i. Metal sleeves through foundation walls must extend to undisturbed earth to prevent shearing. j. The top of the conduit must be buried at least 24 inches below the ground surface. Warning tape equipped with a metallic tracer shall be placed 12-inches above top of conduit bank. l. Underground conduit must be terminated at the designated property line with a minimum cover of 24 inches. m. Conduit must be encased in concrete when the following conditions exist: minimum conduit depth cannot be attained, conduits must pass under roads, driveways, or railroad tracks, or bend points might be subject to movement. Reinforcing bars within the concrete must be used at any location subject to potentially extreme stress. CR shall inspect and approve all conduits prior to encasement. n. The inside-the-building end of the conduit must be sealed to prevent rodents, water, or gases from entering the building.

o. There shall be no more than two 90° bends between pulling points on all conduits. All bends must be long, sweeping bends with a radius not less than 6 times the internal diameter of conduits 2 inches or smaller, or 10 times the internal diameter of conduits larger than 2 inches.



p. All conduit bends shall be concrete encased to prevent a “burn-through” by the pull rope during large cable installations. q. Conduit must be positioned on the field side of the poles (the side that is protected from the normal flow of traffic). On joint use electrical poles, the telecommunications conduit shall be located 180 degrees any electrical conduit, when possible, but no less than 90 degrees.

2. Sizing Underground Conduit. The quantity and size of underground entrance conduits are based on the anticipated number and type of telecommunications circuits that will be brought into the building. UC Davis requires two entrance pairs per 100 square feet of usable office space. The following table shows the data for the quantity and size of underground entrance conduits. Reference Table 13-1.

Table 13-1 Conduit Size Requirements

Copper Entrance Pairs Conduits Required 1 - 1000 1each 4-inch conduit + 2 spare 4-inch conduits 1001 - 2000 2 each 4-inch conduits + 2 spare 4-inch conduits 2001 - 3000 3 each 4-inch conduits + 2 spare 4-inch conduits 3001 - 5000 4 each 4-inch conduit + 2 spare 4-inch conduits 5001 - 7000 5 each 4-inch conduits + 2 spare 4-inch conduits 7001 - 9000 6 each 4-inch conduits + 2 spare 4-inch conduits

Note: Two spare 4-inch conduits must be brought into every building in addition to the quantities specified above.



Specification 14 Electrical Protections, Bonding and Grounding


1. Electrical protection must be provided for cables that are subject to lightning, power contact, ground potential rise, or induction. The minimum protection is a tri-element gas module device.

2. Cables exposed to power sources must be provided with sneak current protectors that will protect cables against voltage and power surges by interrupting the current or by grounding the conductors.

3. Ground systems must conform to the NEC and NESC specifications. Approved ground systems are:

a. Building entrance power ground from transformer – single point b. Building steel (the metal frame of the building itself) c. Building footing (a concrete-encased electrode near the bottom of the building’s foundation). d. Ground ring (20 feet or more of bare copper wire in direct contact with the earth-it encircles the building). e. Metallic power service conduit, enclosure, or grounding electrode f. Ground rod or pipe

4. Equipment single point grounds must be grounded to the building grounding systems as defined in ANSI/TIA/EIA-607 (1994) Commercial Building Grounding and Bonding Requirements for Telecommunications.

5. Riser cables must be grounded at the point of origination and at any floor in which pairs leave the cable sheath. Riser cable sheaths must be bonded to approve grounds in the ER/TR (ADF/BDF/IDF)’s. Reference Figure 14-1

6. Lateral cables must be bonded to approve grounds in the ER/TR (ADF/BDF/IDF)’s.

7. Cable sheaths of cables entering a building must be bonded to an approved ground at the building entrance location.

8. Protector panels will be wired to an approved ground by the straightest and shortest means.

9. The NEC requires a listed primary protector (such as an Entrance Building Protector with 4B1E-W Protector Modules) at both ends whenever an aerial communications cable is routed across a street and whenever aerial or underground campus circuits may be exposed to accidental contact with power conductors operating at over 300 volts.

10. Exposed refers to an outdoor communications cable’s susceptibility to electrical power system faults or to lightning or other transients. A cable is also considered electrically exposed if any of its branches or individual circuits is exposed.



11. A lightning exposure guideline is included in the NEC Section 800-30(a). It states that inter-building circuits are considered to have exposure to lightening unless cable runs are 140 feet or less, buried with a properly grounded shield. The NEC also states that the shield must be bonded to the building’s ground electrode system at each end.

12. NEC Article 100 and Section 250-70 define bonding as the permanent joining of metallic parts to form an electrically conductive path that will assure electrical continuity and the capacity to conduct safely any current that is likely to be imposed.

13. Bonding conductors are not intended to carry electrical load currents under normal conditions, but must carry fault currents so that electrical protection (circuit breakers) will properly operate.

14. A #6 AWG copper conductor will be used to bond the communications components to the ground. A larger conductor will be used if the ground source exceeds 5 ohms.

15. The electrical contractor must provide access to a bonding connection at the electrical service ground during new construction (NEC 250-71(b)). A telecommunications main grounding busbar (TMGB) must be specified in the ER/TR with an approved ground connector back to the electrical service ground point.

16. A telecommunications grounding busbar (TGB) must be specified for each ER/TR in the building. Each TGB will have a #6 AWG conductor back to the TMGB.

17. In a renovation or remodeling project where a suitable ground to the electrical service ground is not available, a grounding electrode will be installed in accordance with the NEC Section 250-83. Note: a metallic water pipe connected to a utility water distribution system is no longer the first choice for a grounding electrode. The NEC recommends the ½ inch diameter, 5 foot ground rod be used.

18. Communications bonding relies on short direct paths that have minimum resistive and inductive impedance:

a. Bonding conductors must be routed with minimum bends or changes in direction. b. Bonding connections must be made directly to the points being bonded, avoiding unnecessary connections or splices.

19. All ground attachments shall be properly tagged and labeled in accordance with TIA/EIA-606.

POLICY

A. General

1. UCD respects the privacy of electronic communications while seeking to ensure that UCD administrative records are accessible for the conduct of the University's business. Section 310-16 provides policies and procedures for accessing an individual's records, with or without the individual's consent. 2. In compliance with Federal law, audio or video telephone conversations shall not be recorded or monitored without advising the participants unless a court has explicitly approved such monitoring or recording.

b. Participants shall be informed when a call is being monitored or recorded for the purpose of evaluating customer service, assessing workload, or other business purpose permitted by law. UCD units that monitor or record telephone calls shall provide an alternative method of doing business with the University to clients who do not wish to be part of a monitored telephone call.

B. Equipment used on the campus phone system

a. UCD Emergency Services shall record 911-type emergency calls in accordance with Federal and State laws and regulations.

3. To avoid damage to the system or disruption of services to customers and to prevent potential security violations, only personnel authorized by CR may have access to distribution closets. Customers may not reroute any internal wiring. The Director of Communications Resources, the Vice Provost--Information & Educational Technology, or their designees must approve exceptions to this policy. Exceptions are normally granted only for the placement of life safety equipment and without departmental key access to the closet.

Multi-line telephone sets used on the campus system must be those approved and provided by CR. Departments may select their own single-line sets or choose to purchase single-line sets available through CR. All telephones used on the system, including those in residence halls, must be FCC approved.

C. Incidental personal use of telecommunications resources

University users may use telecommunications resources for incidental personal purposes provided that it does not (1) directly or indirectly interfere with the University's operation of these resources; (2) interfere with the user's employment or other obligations to the University; or (3) burden the University with noticeable incremental costs. Students, staff, faculty, and University affiliates should use their personal calling cards or other personal resources when making toll calls. Departments shall seek reimbursement for toll charges due to incidental personal use by employees.
