Standards

Wiring Standards

Major advances in telecommunications technologies have taken place in the past two decades and those advances have resulted in unprecedented acceptance of networking by the client community.  That acceptance has meant:

  • More demand for network services and the associated network connection equipment.
  • Upward pressure on network speeds.
  • Demand for better and friendlier user station connections.
  • Changing requirements for connection mediums.

The most basic of networking elements, wiring, has had to keep pace with the networking advances and changes.  The days of the old twisted copper pairs with their attendant technologies, installation procedures and physical layouts have given way to advanced wiring techniques, facilities, planning, processes and indeed, more specialized types of cable.  Modern networking success or failure rests on access to the right type of wiring.

The State of South Dakota has, in most locations, been able to stay current with wiring technologies. At some point there will be a need for some expensive and time consuming wiring upgrades, wiring fixes, testing and other major wiring revisions.

Introduction 

The term “state”, for purposes of these Standards, will include the State of South Dakota, South Dakota Higher Education, State institutions, and state personnel and facilities.

In addition to any standards set forth by the state, the national ANSI/TIA/EIA standards will be used as rules and guidelines in any state facility.  Contractors are expected to be familiar with all applicable national standards.  In terms of this document the most important of such standards, although others may apply, are:

  • ANSI/TIA/EIA-606 – the Administration Standard for the Telecommunications infrastructure of Commercial Buildings.  This standard specifies a generic voice and data cabling system that supports multi-product, multi-vendor environments.  Also addressed are planning and installation of a structured cabling system and performance and technical criteria for cable and connecting hardware.

  • ISO/IEC 11801 – Information Technology-generic cabling for customer premises.  This standard addresses specifications for telecommunications installations, requirements for a structured cabling system, performance, topology, cabling distances, installation practices and channel performances.  Category 5, 6, and 7 are covered in 11801.

  • ANSI/TIA/EIA-568-A – which covers UTP cabling categories.  There are a number of addenda to this standard, including the ones with cross reference charts for cabling specifications.

  • TIA/EIA TSB75 – Open Office Cabling.  This standard provides additional specifications for horizontal cabling in areas with movable furniture and partitions.

  • ANSI/TIA/EIA-569-A – This standard has applications pertaining to telecommunications closets.

  • TIA/EIA TSB67 – Transmission Performance Specifications of Field Testing of UTP Cabling Systems.

  • TIA/EIA TSB72 – Centralized Optical Fiber Cabling Guidelines – which contains information and guidelines for single tenant and centralized optical fiber cabling.

The state will utilize multimode and single mode fiber, fiber apparatus solutions, high speed cable, Gigabit Ethernet, channel solutions, test equipment, fiber-duplex data networks, fiber-to-the-desk, unshielded twisted pair, and copper cabling, voice grade and T1 ABAM.

All standards will be based on an approach called Structured Building Wiring System, often referred to as BWS.  This type of system develops building wiring plans, for low voltage telecommunications systems and networks that create flexible and modular wiring systems capable of adapting to new requirements and technologies.  A Structured Building Wiring System will support changing technology requirements and will be capable of being easily modified to support additional workloads or requirements.

Within the Structured Building Wiring System is a standard of a Redundant Riser Backbone, which is a basic cabling infrastructure plan for a building consisting of multimode and single mode strands of fiber, voice grade copper pairs, pairs of T1 ABAM cable and a P3-500JCAR video riser coaxial cable.  Cable sizes are determined by the size of building, technology needs and number of occupants.

Fundamental concepts of a Structured Building Wiring System are as follows:

  • Over the life of any state owned or rented building major or minor remodeling occurs at least every five years.  Our Standards recognize changes will occur and future enhancements or expansions will be a consideration at remodeling or construction time.

  • Over the life of any state owned or rented building telecommunications equipment and functionality will change dramatically.  These standards will recognize that fact and stay independent from specific vendor equipment or media.
  • Telecommunications now either provides facilities for or is directly involved with other building systems such as environmental controls, security devices, audio, visual, alarms and sensory equipment and all standards must recognize that fact during and after the planning and installation phases. 

  • Policies within different telephone company areas may vary, in terms of delivery of service.  This may require some standards modification.

  • Standards, to be effective, must apply to all entities who are involved in planning, engineering, construction, remodeling or maintenance of State owned or rented buildings.

Design and Standard Considerations

There are seven subsystems to consider in a Structured Building Wiring System. 

 1.1.     Building Entrance:

1.1.1.  Building entrance facilities provide the point at which outside cabling interfaces with the intrabuilding backbone cabling.  The physical requirements of the network interface are defined in the EIA/TIA-569 Standard.

1.2.     Equipment Room:

1.2.1.  The design aspects of the equipment room are specified in the EIA/TIA 569 Standard.  Equipment rooms usually house equipment of higher complexity than telecommunications closets.  Any or all of the functions of a telecommunications closet may be provided by the equipment room.

1.3.     Backbone Cabling:

1.3.1.  The backbone cabling provides interconnection between telecommunication closets, equipment rooms and entrance facilities.  It consists of the backbone cables, intermediate and main cross connects, mechanical terminations and patch cords or jumpers used for backbone-to-backbone cross-connection.  This includes:

    1.3.1.1.  Vertical connection between floors (risers).
    1.3.1.2.  Cables between an equipment room and building cable entrance facilities.
    1.3.1.3.  Cables between buildings (interbuilding).

1.3.2.  Cabling types recognized and maximum backbone distances are specified in the TIA/EIA-568A Design Considerations and those specifications will be the standards.  However, backbone distances are always dependent on the application and 568A distances, as shown, are maximum.  Note also the 90 meter distance for STP applies to applications with a spectral bandwidth of 20 MHz to 300 MHz. A 90 meter distance also applies to UTP at spectral bandwidths of 5 MHz - 16 MHz for CAT 3, 10 MHz­20 MHz for CAT 4, 20 MHz­100 MHz for CAT 5 and 5e, 200 MHz for CAT 6

    1.3.2.1.  In summary the actual distances depend on the type of system, data speed and the manufacturer's specifications for the system electronics and the associated components used (i.e., baluns, adapters, line drivers, etc.).  Current state-of-the-art distribution facilities usually include a combination of both copper and fiber optic cables in the backbone.

 1.4.     Other Design Requirements:

1.4.1.  Star topology
1.4.2.  No more than two hierarchical levels of cross-connects
1.4.3.  Bridge taps are not allowed
1.4.4.  Main and intermediate cross-connect jumper or patch cord lengths should not exceed 20 meters (66 feet)
1.4.5.  Avoid installing in areas where sources of high levels of EMI/RFI may exist
1.4.6.  Grounding should meet the requirements as defined in EIA/TIA 607
1.4.6.1.  Note: The Contractor must consult with equipment manufacturers, application standards and system providers for additional information when planning shared sheath applications on UTP backbone cables.

1.5.     Telecommunications Closet:

1.5.1.  Telecommunications closets are basic service requirements.  Each closet will be approximately 150 square feet and shall be located within 90 cable meters of all telecommunications outlets.  If there are limitations on the 90 cable meters standard then more than one closet will be required.

1.5.2.  The closet(s) will contain termination equipment for service entrance wiring and horizontal telephone, data and video wiring, per OTC standards.  Voice terminations shall be Category 5e 110 type or if existing is 66 block, duplicate existing. All will be wall mounted the same as with all service electronics.  Standard 7’ by 19” equipment racks will be provided for Category 5e data patch panels, fiber patch panels, network electronics and backbone connection equipment.  Grounding and service entrance protection shall be provided per NEC requirements and OTC standards.

1.5.2.1.  Horizontal wiring from the Telecommunications closet(s) to each telecommunications outlet shall be provided.  Wiring for voice and data wiring shall be an individual enhanced Category 5e cable for each jack per OTC standards.  Wiring for video services shall be RG-6.  Wiring from the outlet to the ceiling space will be concealed in the wall whenever possible and if concealment is not possible wiring will be provided in surface mounted plastic raceway.  Wiring extended above accessible ceilings may be run in conduit, cable tray or “J” hooks.  Wiring extended above drywall ceilings must be in conduit, with all junction boxes accessible.

1.5.3.  Outlets for telecommunications services shall be provided throughout the facility.  Each outlet shall contain voice, data and video jacks as required, mounted within a common faceplate.  Voice and data jacks shall be Category 5e.  Video jacks shall be “F” or BNC connectors depending on application. Exact locations for each outlet shall be determined during the design process.

1.5.4.  All design, installation and materials shall be in accordance with applicable BICSI, EIA, and TIA standards.

1.6.     Horizontal Cabling:

1.6.1.  The specified topology will be Star.  The horizontal cabling system extends from the work area telecommunications outlet to the telecommunications closet and consists of the following:
1.6.1.1.  Horizontal Cabling
1.6.1.2.  Telecommunications Outlet

 1.7.     Cable Terminations:

1.7.1.  Cross-connections
1.7.1.1.  Three options are recognized as options for horizontal cabling:
1.7.1.1.1.  4 pair 100 ohm UTP cable (24 AWG solid conductors) - maximum distance of 90 meters.
1.7.1.1.2.  62.5/125  optical multi mode fiber cable
1.7.1.1.3.  Single mode fiber
