Voice/Data Cabling Requirements

Information Transport System Infrastructure Standard

Backbone networks for voice and data (including CAT-5E, CAT-6 and fiber optics) will be designed and installed according to National Standards including TIA/EIA and BICSI, so building infrastructure will meet the needs of any State tenant that might move into the space.

Installation Requirements

  • All new voice communications cabling systems installations will utilize CAT-6 components. Terminations will be in CAT-6 Outlets and to a 24 or 48 port patch panel. Cable will be gray. NOTE: CAT-5E components on “110 blocks” may be used for expansion of existing installations based on the CAT-5E standard.
  • All new data communications cabling systems installations will utilize CAT-6 components. Terminations will be in 24 or 48 port patch panels depending on project requirements and the 4-pair CAT-6 data communications cable will be green. NOTE: CAT-5E components may be used for expansion of existing installations based on the CAT-5E standard.
  • All cabling systems installations and components shall conform to all Category-6 standards and specifications of TIA/EIA 568A Standard.
  • Multi-mode Fiber Optic cable shall be used where distances and bandwidth requirements dictate. This is normally any distance beyond 100 meters or any connection between buildings with different power sources. The state is transitioning from using 62.5 micron to 50 micron fiber optic cable. It is imperative that this be discussed on each order.
  • A minimum of six strand multimode fiber-optic cables terminated in locked metal distribution boxes shall be used in all installations. Strands shall be terminated with ST or LC connectors depending upon the environment in which the panel is installed. The choice of loose or tight tube buffered cable and the type of jacket shall be based on the environment in which the cable is to be installed.
  • All cable, UTP or fiber-optic cable shall meet building codes for Plenum environment, riser, or horizontal use.
  • All cable should be installed, fastened and/or wrapped with the minimum bend radius and minimum jacket removal for CAT-6 cabling as well as appear neat and orderly. Installation best practices should be followed in order to avoid bad test results or ambient noise. Best practices include but are not limited to, routing cables through available cable trays and raceways and never resting on ceiling tiles.
  • All cable runs shall be clearly labeled on each end of the cable and on the patch panel and on the outlet as required by EIA/TIA 568 Standard.

Standard Configuration

  • It is recommended that a minimum of two (2) data outlets be provided at every workstation. Modular outlet systems shall be used.

Testing and Documentation Requirements

Testing and As Built documentation will be provided on CD-ROM or diskette. The following test results will be delivered to the ADS Telecommunications Section within two weeks of work completion.

  • Provide certificate of accuracy and/or recalibration report from all equipment used to perform the cable tests.
  • Perform full electronic testing on all cables with cable scanner reporting the results for the following:
  • Signal to Noise Ratio
    • Ambient Noise
    • Cable Length
    • Wire Map
    • Date of Test
  • All CAT-5E installations will be tested to meet the 100Mbps standards.
  • All CAT-6 installations will be tested to meet the 1Gbps standards.
  • All multi-mode fiber installations (horizontal and backbone links) will test link attenuation and optical loss on each fiber bi-directionally at 850 nm and 1300 nm. ADS will confirm test results fall within the acceptance range based on current TIA/EIA requirements, distance metrics and other requirements.
  • As-built drawing package will be delivered to the ADS Telecommunications Section within two weeks of work completion and will include:
    • Copy of or original floor plan with actual location of all modular jacks (station) with identification or numbers clearly labeled.
    • Copy of all change orders or requests executed during the project which impacted the floorplan or cable routes original specifications.
    • Identification of cable routes, backboard design and the use/type of firestop used in horizontal and vertical pathways if included in the design.

Certification and Warranty Requirements

  • The manufacturer of the termination hardware utilized shall train installers. Contractors shall provide a letter of support and warrantee documentation from the manufacturer on the cabling termination hardware used.
  • Installers will provide ADS with primary and secondary manufacturer’s certificates and product warranties for all cable plant components utilized during projects. SOV current cable plant system utilizes Ortronics hardware.

Building Considerations

  • Telecommunications Closets should be provided on each floor of a building. Closets should be stacked one directly above the other in multi-floor buildings. A minimum of two 4-inch sleeves must be provided vertically between each closet. Additional sleeves may be required at the discretion of the ADSTelecommunications Manager.
  • Telecommunications Closets should be centrally located in the building to minimize distance of all horizontal cable runs.
  • Telecommunications Closets must be adequately ventilated for all equipment that might be located within. Depending on location and configuration these closets might contain Key Telephone System CPUs, ISDN Power Supplies, UPSs (Uninterrupted Power Sources), DSU/CSUs, Routers, Hubs, and Local Area Network Servers.
  • Adequate lighting, shelving, and individual A/C power outlets must be provided.
  • Adequate backboard and or floor space for racks must be provided for mounting telecommunications terminal blocks and Data Communications Patch Panels on the wall or in racks. Backboards will be ¾ inch plywood painted with gray or white fire-retardant paint.
  • The State Buildings and General Services department and ADS Telecommunications will meet with the architect to determine the size and requirements of the telecommunications closets. The local telephone company that provides dial tone in the area must be consulted on cable entrance and termination.
