PART 3 - EXECUTION

3.1 Structured Cabling Systems Definition

A. "Structured Wiring" is a philosophy of pre-installing necessary cabling to device locations to be available to be used as these devices come on line. Moves and changes are affected at structured patch fields with the permanently installed links being relatively unchanging. In most basic form, a structured wiring system consists of horizontal wiring and appropriate connecting hardware, with backbone cabling connecting the horizontal sub-system to the main and intermediate distribution areas.

B. The following terms for various sub-systems are defined within the ANSI/TIA 568-C series of standards and shall be referred to throughout this document. 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 room (TR) (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 Telecom Rooms within a building or between buildings.

4. The horizontal cabling consists of the physical media used to connect each outlet or device to a TR. Various types of cable can be used for horizontal distribution. Each type has its own performance limitations, size, and ease-of-use.

3.2 REGULATORY REFERENCES - CONCLUSION

A. 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


270500 - 4

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 technologies involved.

B. 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.

C. 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.

3.3 GENERAL INSTALLATION GUIDELINES

A. This section emphasizes some important details and installation processes for the structured cabling system. For complete guidelines see "Regulatory References" above.

B. Each individual 4 pair cable will be used for one service unless the data link application is designed to do so (as in VoIP voice over Internet Protocol). Splitting of pairs from a 4 pair cable across more than one jack is forbidden.

C. When installing Unshielded Twisted Pair (UTP) it must be compliant with industry standards. When routing cables through walls and ceilings the Contractor must maintain all distance limitations from power cable and devices as outlined in TIA 569-B.

D. 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 installation process to prevent any undue stress on the cable. Contractor shall adhere to all manufacturer's guidelines on cable handling, as well as the recommendations in TIA 568-C.0

E. 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.

F. 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.


270500 - 5

G. 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.

H. All Contractor installed raceways shall be installed within the building so as not to interfere with or block any existing fixture, painting, mural, or artwork presently existing in the building.

I. All Contractor installed raceways shall be level and plumb when run vertically or horizontally along walls or ceilings. On raceway runs under a height of 8 feet from the floor, Contractor shall glue all fittings to the raceway using PVC cement.

J. All service loops on cabling links shall be according to TIA guidelines with a minimum 12" copper UTP slack in the work area that should be partially pushed back into conduit and stored in the ceiling space leaving approximately 7" left in the wall box. Contractors shall under no circumstances use "accordion" folds or in any way violate cable bend radius to store service loops in the work area.

K. Service loops in the telecommunications rooms shall also meet TIA requirements of 3 feet for copper and a minimum 3 meters slack for fiber backbones. TR slack shall be appropriately and neatly stored in managers, on pathways or on walls as necessary for that environment using storage appliances built to that purpose.

L. All penetrations shall be fire stopped according to national and local codes.

M. All Category 6 cables will be terminated on Panduit angled standard density Patch Panels and performance verified according to test procedures located in the testing and acceptance section of this document. For actual part numbers of copper cable and termination appliances, see the parts list (Attachment 1) at the end of this document.

N. Coax cables shall be installed only in maintaining legacy systems. Additions to such systems shall be terminated on eight port splitters with a minimum of 6” between rows to connect all coax within a TR. The Contractor will use T&B snap and seal connectors. The Contractor shall place a 75-Ohm terminator cap on any unused splitter output ports.

O. The device end of legacy coax cables will be terminated in self-terminating inserts placed in an appropriate faceplate to match the installed systems. Any conduits supplied by the electrical sub-contractor for support of installed video locations are to be 1” in size.

P. The Contractor shall test any additions to legacy coax cables and provide documentation of these tests as outlined in this document.

Q. The wiring Contractor will make the head end connection to the cable TV Vendor’s entrance termination when making additions to any legacy broadband systems.

R. The Contractor placed drops for Wireless Data Access Points (WAP’s) shall be terminated at the serving TR 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.

S. The device end of access point drops will be terminated with a Panduit RJ45 Category 6 ivory Mini-com jack in 2-port surface mount box. No service loops are needed on WAP locations.


270500 - 6

T. 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 TG-style jack and installed in a two port flush mount or surface mount box.

U. The Contractor will be responsible for mounting the Wireless Access Points and covers in hard deck applications. For specific parts, see parts list (Attachment 1) at the end of this document.

V. All Wireless Access Points that are placed above drop ceiling will have a 1” wide label placed on the grid below the WAP location. This label will be 1” wide and have black text on an orange label.

W. Any conduits provided for the communication outlets are to be 1” in diameter with no daisy chaining allowed between work areas or speakers in audio systems.

X. In locations using Wiremold raceway, the Contractor may match the raceway previously installed. The legacy Wiremold is type 2400 or 4000. A 1” conduit will be supplied for each 10’ of Wiremold placed. All new installations shall use raceway types as described in the project documentation. For Panduit non-metallic raceway, see attachment 1 at the end of this document.
