8 Section 1 STRUCTURED CABLING SYSTEM OVERVIEW 1.1 INTRODUCTION Denver Public Schools (DPS) Department of Technology Services (DoTS) has issued the following document of structured cabling standards. The standards group that is the driving force behind international wiring standards is the Electronic Industries Alliance/Telecommunications Industries Association (EIA/TIA). This group developed the standards that have been adopted by cabling Contractor s of structured cabling products. This standard has been designated EIA/TIA 568-B. All DPS personnel and outside Contractor s who are responsible for the task of installing and/or repairing any communications cabling in all DPS sponsored facilities must adhere to the specifications outlined in this document as well as the following standards; EIA/TIA 568-B.1, 568- B.2, 568-B.3, 606, 607, and 569. The purpose of this document is to provide additional instructions for the planning, design and installation of an end-to-end Category 6 cabling system. This document will encompass the structured wiring, the system components, proper installation practices, cable testing, and most importantly the documentation. For specific installation, testing, grounding, bonding, and documentation guidelines please refer to the specific sections in this document. 1.2 STRUCTURED COMMUNICATIONS CABLE SYSTEM GENERAL SPECIFICATIONS A structured wiring solution is only as robust as its weakest component, therefore all wires and connections should be terminated and tested to the 568-B Annex B specification to comply with the minimum required performance. When planning and installing a structured cabling system for DPS the Contractor must pay particular attention to all components used, ensuring they conform to the above-mentioned specification. Since the ANSI/EIA/TIA-568-B Category 6 cabling system is the DPS required standard, all cable and components used must adhere to this standard. All installations should be planned with as few connections possible between the wall plate and patch panel. The DPS network design will be a star topology. By pre-wiring all possible locations in a new or existing building in a star topology, all moves, changes and additions can be made quickly and easily by moving patch cables in a centralized telecommunications closet (TC) STRUCTURED SYSTEMS DEFINITIONS The ANSI/EIA/TIA 568-B standard is a detailed document that specifies a generic telecommunications wiring system for commercial buildings that will support a multi-product, multi-contractor environment and establishes performance and technical criteria for various wiring system configurations for interfacing and connecting their respective elements, (ANSI/EIA/TIA-568-B-1, 2002, page 1 section 1.1). Topics covered by the 568-B standard 8

9 include horizontal cabling, backbone cabling, telecommunications rooms, workstation outlets, cable and connecting hardware plus much more. The ANSI/EIA/TIA 568-B standard specifies minimum requirements for telecommunications cabling with a commercial building, up to and including the telecommunications outlet/connector, and between buildings. According to the standard the cabling systems consists of four functional subsystems: 1. The entrance facility (EF) is the point where the outside plant cables and associated hardware is brought into the building. The entrance facility may be used for public network services, private network customer services or both. The demarcation points between carrier and customer and over-voltage protection devices are located here. 2. The telecommunications closet (TC) (often referred to in the industry as MDF/IDF) is a centralized space for telecommunications equipment (e.g. PBX, computing equipment, video switch, etc.) that serves users in the building. This room is also, where the horizontal distribution cables are terminated. All recognized types of horizontal cabling are terminated on compatible connecting hardware. Similarly, recognized backbone cables are also terminated in the closet. Device activation is done with jumpers or patch cables to provide flexible connectivity for extending various services to users at the telecommunications outlets. 3. The backbone cabling provides interconnections between telecommunications closets, equipment rooms and entrance facilities. It consists of the backbone cables, main and intermediate cross-connects, mechanical terminations and patch cords or jumpers used for cross-connection. The backbone may connect closets within a building or between buildings. 4. The horizontal cabling consists of the physical media used to connect each outlet or device to a TC. Various types of cable can be used for horizontal distribution. Each type has its own performance limitations, size, and ease-of-use CABLE SPECIFICATIONS A structured wiring system is one in which the main components of the system, once installed, seldom changes. In its most basic form, a structured wiring system consists of horizontal wiring and appropriate connecting hardware. The following are the main components of this system: Horizontal Cabling: This wiring runs from the TC to the workstation outlet. For each workstation outlet, there will be a specific number of Category 6 and/or video cables depending on room location and user application. DPS standards are to install two teacher stations and one student station in each classroom. Teacher stations consist of three Category 6 cables and one RG6 coax cable. Student stations consist of three Category 6 cables. DPS also utilizes fixed video and projector stations. Fixed video consists of one Category 6 cable and one RG6 coax cable. The fixed video application is predominantly installed in new construction and remodeled schools; however, this application can be implemented in existing schools. Projector location consist of one Category 6 cable to the closest TC and one Category 6 cable to the adjacent Teacher location that will terminate on both ends with a 15 pin DB connector, Panduit part number CMD15HDEI. Horizontal cables shall be installed without splices and continuously supported. Horizontal cabling requirements for the DoTS facility will be provided at the pre-bid conference. 9

10 The cable used for horizontal wiring is Category 6 four pair unshielded twisted cable under one jacket and comes in two forms, PVC and plenum. Building codes require plenum rated cable when cable is run above certain types of dropped ceilings. DPS has standardized on plenum cable for all Category 6 installations. When planning any installation, it is imperative that each workstation will be identified and located in relation to the TC. All horizontal wiring must not exceed (295 ft.). This is actual tested cable length, not the physical distance between the TC and the workstation outlet. If any horizontal cabling run is more than the 295 feet, it must be submitted to the DoTS Project Manager for written exemption approval prior to being installed. Backbone Cabling: This is the cabling that provides the interconnection between various TC s and the EF whether in the same or different buildings. The backbone cabling may include copper, fiber and coax cabling, cross-connects mechanical terminations and patch cables used to provide backbone-to-backbone cable connection. Connecting Hardware: Connecting hardware is used to terminate the horizontal wiring in the TC or at the workstation outlet. Typically, patch panels used in the TC and wall plates used at the desktop, fall into this category. The 568-B standard calls for 8P8C (8-position, 8 conductor RJ-45 type) jacks to be used in these types of installations. Patch panels provide multiple 8P8C jacks, often in multiples of twelve, and are designed to fit into racks or cabinets with 19-inch mounting rails. Wall plates should be a multi-media surface mounted sloped vertical or horizontal version and be able to accommodate other types of connectors, such as RG-6 and VGA, or for use or non-eia/tia applications. Patch Cables: Patch cables are used to make the physical connection between the structured cabling and the network and telecommunications equipment. At the TC, patch cables are used to facilitate fast and easy moves, changes or additions to the network. At the desktop, patch cables enable connectivity from the communications outlet to the end user s network device. See section 1.5 for patch cable quantities and specifications. All patch cables should be Category 5E INSTALLATION GUIDELINES Never run more than one type of service (e.g., Token Ring and 10 Base-T) data and telephone in the same cable. The rule of thumb is if the pairs are under the same jacket; use them for only one system. 1. When installing Unshielded Twisted Pair (UTP) it must be compliant with industry standards. When routing cables through walls and ceilings the Contractor must keep the cable a minimum of six inches away from sources of electromagnetic interference (EMI) and radio frequency interference (RFI). Likely sources of EMI/RFI include fluorescent lights, electric panels, and light dimmers. Phase transformers and electric motors, such as those found in air handlers and elevator rooms can also generate high levels of interference. In addition, never run data cables in the same conduit as electrical wiring. 2. Pulling a cable with too much force or bending it too sharply can change the electrical characteristics of the cable and degrade its performance, so care must be taken during the 10

11 installation process to prevent any undue stress on the cable. The cable should move freely at all times and be protected from sharp edges while it is being pulled. When pulling around tight or multiple corners, two or more people should be used to guide the cable and prevent damage to it. In addition, care should be taken when using any type of cable tie. Cables should be lightly tightened to avoid any visible stress, which can change the characteristics of the UTP cable. 3. All Contractor installed raceways shall be installed in practical alignment with either the building or structures within the building and securely attached to the building by use of plastic anchors, toggle bolts, expansion anchors or other method appropriate for the application and approved by the DoTS Project Manager. See approved anchoring document. All Contractor installed raceways shall be installed within the building and should not interfere with or block any existing fixture, painting, mural, or artwork presently existing in the building. All Contractor installed raceways shall be level and plumb when run vertically or horizontally along walls or ceilings. All transition and coupling fittings for installed LD10, TG 45 and TG 70 raceways will be super glued. 4. DPS does not want service loops left on the cabling. When terminating the device end of the cabling, pull 12 of wire out of the outlet box, trim and terminate the cabling. After termination, push the cabling back up the conduit, leaving approximately 7 of wire in the box. Allow the remainder to remain slack as it exits the upper end of the conduit and caulk the conduit with National Fire Protection rated fire caulking. 5. All Category 6 cables will be terminated on Panduit angled standard density Patch Panels. All Category 6 cables will be tested to Panduit and EIA/TIA 568B Category 6 specifications by the Contractor and documentation of these tests supplied as outlined in this document. Category 6 cables will be plenum (blue in color). 6. All coax cables shall be terminated on eight port splitters with a minimum of 6 between rows to connect all coax within a TC. The Contractor will use the approved T&B snap and seal connector for all coax. The Contractor shall place a 75-Ohm terminator cap on any unused output of the splitters. The device end of the coax cable will be terminated in self-terminating inserts placed in a variety of faceplates depending on the application. Any conduits supplied by the electrical sub-contractor for video location are to be 1 in size. The Contractor shall test all coax cables and documentation of these tests supplied as outlined in this document. The wiring Contractor will make the head end connection to the cable TV Vendor s entrance termination. 7. The Contractor placed drops for Wireless Data Access Points (WAP s) shall be terminated at the serving TC end in the Panduit patch panels, using black jacks, with the other Category 6 terminations and labeled in the same fashion as all other cables. The device end of the cable will be terminated with a Panduit RJ45 Category 6 ivory Minicom jack and 20 of cable coiled and left supported above the drop ceiling. In all other applications (i.e. hard deck ceiling or wall penetration), the device end of the cable will be terminated with a Panduit RJ45 Category 6 ivory Minicom jack and installed in a two port flush mount or surface mount box. The Contractor will be responsible for mounting the Wireless Access Points and covers in hard deck applications. 8. Any conduits provided for the communication outlets are to be 1 in diameter with no looping between outlets. The conduits for speakers shall be ½ and may be looped between multiple speakers. There are some locations utilizing Wiremold raceway. The Wiremold is type 11

12 4000. A 1 conduit will be supplied for each 10 of Wiremold placed. The correct Wiremold faceplate to be used will be G4048R. The Panduit faceplate used in conjunction with the Wiremold is CFPHS2IG which is a two port sloped faceplate. The Contractor will provide color-matching faceplates with color matching inserts. 9. Labor and material components will include TC build-out. The Wiring Contractor may be responsible for purchasing and installing additional 4x8x3/4 fire rated plywood backboards. These backboards shall be installed with firebrand showing. The standard number of plywood sheets for the Main TC is three in a PBX application and two in a Key System application. One sheet of ¾ plywood will be installed for each TC. The Contractor shall be responsible for placing and mounting of all equipment racks, wire management, terminating hardware (copper and fiber), ladder racks (including waterfalls), grounding of the ladder racks and Panduit frames, and all labeling. 1.3 BACKBONE CABLING The 295-foot limitation on horizontal cabling runs often necessitates the use of multiple TC s to serve locations spread over large facilities. A means for interconnecting TC s backbone cabling should use a hierarchical star topology, with each horizontal termination point in a TC cabled back to one main termination point in the central TC. This labor and material component will include all copper and fiber optic building backbone or risers. Between the main TC and each intermediate TC the Contractor will place one 100 pair 24 Ga. PVC or plenum tie cable, one 12 strand multi-mode 50/125µm plenum armored fiber optic cable for every 288 Category 6 cables installed, one RG11 and one RG6 PVC or plenum video coax tie, two 18 Ga. 2 pair shielded PVC or plenum ties, two 4 pair Category 6 PVC or plenum data backup ties terminated on yellow jacks in consecutive order and a new pull string. All riser components will originate in the main TC and terminate in their respective intermediate TC locations. In addition, the Contractor will be responsible for providing one 25 pair PVC or plenum cable and two Category 6 PVC or Plenum cables from the IT feed to the main TC. If an existing MDF is to be abandoned, the Contractor will be responsible for installing two four pair Category 6 PVC or Plenum cables between the old MDF and the new MDF. The Contractor will be responsible for all placements, testing, terminating, and labeling of all riser and horizontal cabling and providing the DoTS Project Manager with all electronic test results. 1.4 CONNECTING HARDWARE Angled standard density patch panels will be installed in all MDF and IDF locations. Standard 19 frames with vertical wire management will be utilized in all MDF and IDF locations. However, if there is concern for space or security, a locking cabinet will be provided by DoTS. If the number of Category 6 cables installed in this specific TC exceeds 192, a locking cabinet cannot be utilized. In this instance frame technology will be utilized. Smaller installations or ones with limited floor space can benefit from using wall mount distribution racks. These types of racks provide easy access for cabling to the back of the patch panels and take up no floor space. The DoTS PM will make this determination. See attachment one for specific connecting hardware requirements for the DoTS facility project. 12

13 1.5 PATCH CABLES The quality and performance of the patch cables used for connecting patch panels and wall plates should not be minimized. They are as important as any other component in our structured cabling system. The number of patch cables provided should equal two times the number of station jacks installed. One third of the patch cables will be white and two thirds will be blue. The following table will determine the lengths of each color. All patch cables will be Panduit and will be color-coded to help differentiate between various systems running on the same cabling system. DoTS requires patch cables be color-coded in the following manner: Ethernet data systems Blue Voice White The percentages of patch cables are as follows: Per station jack (1) White & (2) Blue % 5' 48% 7' 34% 10' 15% 14' 2% 20 1% When planning the installation, you must take into account the length of the patch cables. The maximum horizontal cable run cannot exceed 295 feet. In addition, the 568-B.1 standard allows for a maximum patch cable length of 33 feet between the TC and the workstation outlet. If this length is exceeded, the main horizontal cable run must be reduced by the excess amount, so as not to exceed an overall length of 328 feet, including both horizontal cabling and patch cables. DPS/DoTS requires all Category 5E patch cables to be factory assembled. 1.6 APPLICATION TESTING AND CERTIFICATION Once the installation is completed, each cable run must be tested to ensure that they meet or exceed the electrical performance specifications for the intended application. The EIA/TIA provides guidelines for field-testing of installed UTP link for Category 6 compliance. For field testing purposes, a UTP permanent link is defined as one entire cable run, including the workstation outlet, patch panel and the horizontal cable run. 1.7 DOCUMENTATION DPS requires the complete structured cabling system to be documented from TC to work station termination. Each wall plate jack should be marked with a unique identifier that corresponds to a jack on the patch panel in the TC. In addition, the cable test of every permanent link should be a part of the documentation package upon completion of the system. Once this is done, it s a simple matter to make moves, changes or additions, since finding various locations throughout the building is as easy as comparing the identifiers on the wall plate and patch panel. The ANSI/EIA/TIA 606 standard is based on the need to have a unique identifier for all components of the structured cabling systems. 13

14 This standard will apply to all elements of a structured cabling system including the faceplates, cables, patch panels, racks and TC s. The adherence to this standard will allow DoTS to effectively manage the communications infrastructure for Denver Public Schools. The labeling of all infrastructure elements should be consistent across all DPS installations, no matter who performs the installation services. The adherence to the guidelines stated in Section 8 of this document will ensure that all DPS Structured Cabling installations are labeled consistently. The labeling requirements for each element of a structured cabling system are discussed in Section 8 of this document. 1.8 CONCLUSION Denver Public Schools is investing in the latest technology to increase the speed and capacity of our communications systems in order to create a network infrastructure that will support DPS into the future. New applications will allow people to share vast amounts of information in the form of voice, data and video at efficient speeds. However, investing in the latest electronics to support these applications will be an exercise in futility if the installed cable plant cannot support the frequencies and technologies involved. Structured cabling will allow us to build an infrastructure for our communication needs to last well into the future. However, the ability to run any application, to any work area, at any time comes only with the proper planning and installation of a high-performance structured cabling system. Proper planning includes examining all applications, network technologies and telecommunications outlet locations that are currently used or might be used in the future. Accounting for foreseeable scenarios allows the physical infrastructure to be installed once, yet serve our requirements not yet on the horizon. Moves, adds and changes no longer require pulling new cables except when our physical space expands. Choosing the proper media for a new cable installation depends on the applications and services that the network is expected to provide. However, regardless of the other UTP classifications Category 6 will be used for all data and telephony applications. Electrically noisy areas such as HVAC equipment rooms or near motors may lend themselves more to shielded or optical fiber cable. Budgetary concerns should influence the decisions to this point. However, keep in mind that standards-based systems are designed to last a minimum of 25 years from the time of installation. Therefore, cutting corners on the foundation of the network will have ramifications for many years to come and will not be tolerated. A properly planned and installed system will allow Denver Public Schools to spend their time, attention, and limited capital resources in other areas. 1.9 PROJECT COORDINATION If there are any questions or if any additional information is required pertaining to the DPS Project Coordination, please contact: Mike Hall at
