I - GENERAL SPECIFICATIONS

The specifications contained in this document are meant to serve as minimum guidelines for new construction and all renovations. Special needs such as local data processing and energy management may require extensions to these minimums. All special needs should be considered in the actual designs of risers, conduits, cable trays and inter-building cabling.

Contractors are responsible for notifying before any renovation that may involve existing telephone and data cabling. Minimum time frames are required to make sure that cables are disconnected before any conduit or cabling changes are made. Contractors should contact the university project manager or coordinator for submission of electronic notifications to computer services.

This version of the technical standard provides for voice, data, video and other low voltage signaling functions (such as for energy management and security systems) through twisted pair and coaxial cable media with a pathway to each outlet designed for future installations of fiber optical cable. The objective of these wiring standards is to provide acceptable outlets for any telecommunication device which requires connection to other devices, networks or information services serving general university needs.

Each building is likely to require special telecommunication services not specifically addressed in this standards document. West Virginia State University Computer Services, and Educational Technology Center should be contacted prior to establishing an architect's plan for all building renovations and new building construction projects. Campus standards in effect at the time of architect submittals containing communication outlet locations, type of terminations and network equipment provided will be used.

All telecommunications work must comply with all Federal, State and local codes, regulations, and standards with variances adopted as standards by West Virginia State University and the State of West Virginia. Applicable state and national standards include: the latest National Electric Code; REA Standards for Engineering, Construction and Installation; FCC Rules and Regulations; National Electrical Safety Code; Joint Commission Accreditation of Hospitals Code; Life Safety Code; and other special codes that may apply.

All submittals and as built documentation will include at least floor plans, plot plans, conduit locations, cable vault locations, lengths, locations, finish room numbers and wire or fiber numbers. As Builts and all submittals will be made electronically.

Any questions, variances, contractor or vendor meetings, etc should be arranged through the campus liaison or project manager. The project manager should submit a computer service service request at https://mystate.wvstateu.edu

 

II - DEFINITIONS

Communications Outlet - The standard telecommunication outlet provides access to all available twisted pair communication media. It will always contain a minimum of two modular RJ45 receptacles in a double gang box using the Leviton QuickPort Snapin system of connectors and plates. There will be a minimum of 2 runs of CAT5 cable to the IDF-1, IDF-2 or MDF for a maximum of 200 feet.

Entrance Cable - The bulk outside plant cable that enters the building from the campus communication distribution network.

IDF-1 (Intermediate Distribution Frame-1) - The IDF-1 is designated as that point where the outside plant cables connect to the riser cables throughout the building. It is possible to have more than one IDF-1 per building.

IDF-2 (Intermediate Distribution Frame-2) - That point where the riser cables and the station wiring come together. In some situations an IDF-1 may also serve this function.

MDF (Main Distribution Frame) - The MDF is designated as the point where the outside plant twisted pair cable connects to the telephone lines from the local telephone company or the campus' telephone switch line cards to support telephones. The MDF usually serves as an IDF-1 for the building in which it is located.

UPS (Uninterruptable Power Supply) - The type that the load is run off the inverter so that complete power isolation is provided. Runtime on the UPS should be determined using battery life near end of life at full load.

Outside Plant - All transmission facilities used in the distribution of voice, data, or video from the point it leaves one building and enters another. This includes copper, coax, fiber optics, and microwave.

Risers (Building) - The voice, data and coax cable between the IDF-1 and each floor IDF-2 and satellite IDF-2 (rising between floors).

Feeders (Building) - The voice, data and coax cable between the IDF-2 and each satellite IDF-2 (running horizontally on the same floor).

Station Wire - Those wires and cables with terminations at the voice, data or video stations.

Shelter in place phone - Telephone and paging equipment at a location in a building designed for an emergency gathering place that may be used in case of chemical leak, drill or other emergency.

Elevator phone - An automatic calling device used to call for help in case of an elevator malfunction or other emergency. This device is usually in an elevator car. The phone places a call that is unique to that elevator car and includes location information in case the occupant can not speak or convey information.

Fire Alarm Interconnect - A network connection used to monitor and control a fire alarm in a building.

Emergency phone - An automatic calling device used to call for help in case of an emergency. The phone places a call that is unique to that location and includes information in case the caller can not speak or convey information.

As Built Documentation - the plans and documentation showing the comlete floor plans, wire numbering, locations and specifications of a project as of the date of completion and acceptance. This documentation needs to be compatible with the HEFIS, (Higher Education Facilities Information System) http://hefis.wvnet.edu/, and included in that database within 180 days of project completion. Example of As Built Documentation.

The installer of any new conduit or cable tray for audio-visual or communications wiring shall also provide a pull-line. This shall include cable trays and conduit in walls leading to communication outlets.

Horizontal Cable

CMP Type cable must be used in any air plenum installation where conduit is not available. The cable must meet the requirements of the fire marshal or fire authority having jurisdiction over that building.

Cable may be run exposed above ceilings, provided the cabling is supported independent of other utilities, such as conduits, pipes, ceiling support systems.

All wiring inside of rooms should be protected by conduit or other means such as wire mold. All remodel or new construction will provide conduit to all communications outlets as specified above.

Communication outlets should be installed at standard outlet heights depending on room use. No outlets may be placed behind furniture that does not allow for complete and easy access to the communications outlet. At least 1 outlet with 1 data, 1 telephone (VOIP) jack and 1 coaxial connection is installed every 10 foot of wall at standard outlet height. At least 1 data outlet installed high on the wall for wireless access points should be provided for 300 square foot of floor space or where appropriate as determined by RF site survey. The RF site survey is the responsibility of the contractor and an electronic copy will be provided to the appropriate computer services personnel for approval before the job is accepted by the University. Conduit and wiring will also be provided to locations needed for card entry, firealarm, building HVAC, messaging displays, emergency phone, elevator phone, shelter in place phone, video surveillance, and door lock systems. All station cable terminations and interface boxes will be mounted in secure locations at comfortable working height. Locations of interface boxes is preferred in network, HVAC or boiler rooms.

Floor Distribution System

Floor communication closets, IDF-2's, should be located centrally in an area such that the total distance from the closet to any communication outlets on the floor is no greater than 200 feet. One centrally located communication closet is desirable on each floor if the 200 foot distance limitation can be met. Communication closets should be stacked vertically one above the other with at least four (4) four inch sleeves between closets.

Floor communication closets, IDF-2's, must be at least 6 foot by 6 foot (36 square feet). When the minimum size space is provided it should have door opening to permit maximum work space.

Floor communication closets, IDF-2's, may need separate air conditioning with environmental controls to remove heat from electronic communications equipment. High lighting levels are needed. At least four duplex outlets served by one 120V, 20 amp circuit with isolated ground whose feed is from a UPS with 30 minutes run time for a 2KVa load supplied by an emergency generator isolated from any motors, air conditioning, or lighting circuits must be provided.

Twisted pair cable from the communication outlets shall be terminated in the IDF located as close to the outlet as possible, rather than at the single (or major) communications room for the building if the total cable length would be more than 200 feet. These terminations are in turn connected to the building's communications equipment room (IDF-1) by appropriately sized riser cable.

Data and telephone (VOIP) station jacks are to be terminated on Leviton Quickport RJ45 connections on rack mounted patch panels where the voice or VOIP top station jack will be terminated on the top jack in the patch panel and the data or bottom station jack terminated on the patch panel position immediately under the corrosponding voice jack.
