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, data, surveillance, access or control cabling. Minimum time frames are required to make sure that cables are disconnected before any conduit, cabling, fiber, equipment, mounting or physical structure changes are made. Contractors should contact the university project manager or coordinator for submission of electronic notifications to Information Technology.
All notifications by Service request at https://mystate.wvstateu.edu
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 Information Technology 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. Information Technology will only connect systems that meet these minimum guidelines and were previously approved by Information Technology.
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 University Information Technology 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 one modular CAT6 RJ45 receptacle in a double gang box using the Leviton QuickPort Snapin system of connectors and plates. There will be a minimum run of CAT6 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. No IDF will be located where access is through any other room. Direct access via corridor or exterior entrance.
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. No IDF will be located where access is through any other room. Direct access must be from a corridor or exterior entrance.
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. The MDF must be located on the main floor where conduit first enters the building. Direct access must be from a corridor or exterior entrance.
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. UPS must be able to run the full load of the network, telephone, door access, wireless, and surveillance systems for 1 hour if the building has an automatic generator with switchgear or 72 hours if the build does not have a generator. (Kanawha Putnam Emergency Planning)
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. The Shelter in Place Telephone must be placed in a quiet area in the Shelter area enclosed ina campus standard lockable enclosure.
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. The campus currently requires interface to Edwards Fireworks monitoring system.
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 complete floor plans, wire numbering, locations and specifications of a project as of the date of completion and acceptance.
WAP (Wireless Access Point) - A device either ceiling mounted or wall mounted containing radios and antennas to provide connectivity to wireless devices via the current campus wireless system.
