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 Information Technology.

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 hoour 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.

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 comlete 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 cieling mounted or wall mounted containing radios and antennas to provide connectivity to wireless devices via the current campus wireless system.

All cables that are to be connected to or disconnected from the campus communication network must be recorded with the West Virginia State University Information Technology. Cable number, number of bundles, number of pairs, gauge, type, and termination points must be submitted electronically or in writing to be recorded by Information Technology.

Communications Equipment Room (IDF-1)

Space for connection of building circuits to the outside plant shall be provided as a separate room and not shared with other utility services, particularly the electrical service. When possible, it should not be adjacent to the electrical distribution room. Access to the room will be controlled with an access system to be determined by the campus lock smith commonly used by Information Technology. Environmental and security monitoring is required on all MDF's, IDF's and any room designed to house more than 1 router, switch, server, or processor. Currently monitoring is done with network connected Netbotz 355 with door switches and included camera, temperature, and humidity sensors.

Minimum room size is 6 foot by 8 foot (48 square feet). Up to 400 square feet may be required for locations that house remote switching equipment or servers. The room needs to be large enough to accomodate the wall mounted racks or relay frames including required equipment. These rooms require separate air conditioning with environmental controls to remove heat from electronic communications equipment. High lighting levels are needed. A minimum of four duplex outlets on two 120V, 20 amp circuits and 1 30 amp twist lock on a separate 30 amp circuit is required for UPS connection. Outlets should be placed where a 6 foot power cord from the UPS will reach without an extension cord. The feeds must be isolated from any motors, air conditioning, or lighting circuits. Additional circuits will be required if remote switching or servers are installed in the IDF. A separate small electrical sub-panel could provide the proper isolation. The electrical supply must be from an emergency generator backed up circuit. Additional 30 minutes of separate battery backup (UPS) will be provided for each circuit. The UPS must be sized to provide 60 minutes run time at 2KVa when powered from an emergency generator. The room must have a low humidity level and not be subject to a heat source such as steam lines. The room must have a vent for backup heat dissipation. The environmental conditions must be maintained within the specifications of all equipment.

A building earth ground bonded to the electric power ground must be provided by the building contractor. All communications equipment rooms must be connected to this ground by an independent #6 solid copper wire.

Special ventilation may be required for a battery backup system in some buildings. "Maintenance Free" batteries are recommended to avoid this problem.

All 24 port patch panels are to be space at least 2 rack units apart to accomodate network switches while allowing access to repair individual keystones.

All station cable patch panels should be the 24 port type with mounting space immediately above for a POE Layer 2 type network switch. Only 1 ' patch cables are to be used between network switches and station cable jacks as to not require any horizontal cable management and status lights on the network switches to remain visable. ENough space between station cable jack fields shall be provided to allow easy replacement of jacks.

Building Distribution Systems

Horizontal Distribution System

Cable trays are to be used to facilitate present and future communication wiring distribution. A tray on each floor will feed directly back to the communication closet or closets.

The cable trays are to have a cross section of at least 4" by 8". The cable trays are to be installed as low as possible above the ceiling and secured to the side wall with an "L" shaped bracket. It is important for future use that at least 18" clearance be maintained on the free side of the trays and that at least 10" clearance is maintained above the trays. All 90 degree turns should be made by two 45 degree turns where possible. Cable trays are to be accessible with a standard 6 foot ladder.

Each communication outlet will be stubbed out into the cable tray using 3/4 inch conduit for single outlet and 1 inch conduit where two outlets are served by a single conduit. No conduit shall have more than one 90 degree bend or any bend greater than 90 degrees. No bend shall have less than a 12 inch radius.

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 connection is installed every 10 foot of wall at standard outlet height. At least 1 data outlet installed high on the wall, 10" below finished ceiling, 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 architect and an electronic copy will be provided to the appropriate Information Technology personnel for approval before the job is accepted by the University. Conduit and wiring will also be provided to locations needed for card entry, fire alarm, 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 required to be in network 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 two (2) four inch sleeves between closets. Station cables are not to be run between floors.

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 6 fiber multimode.

Data station jacks are to be terminated on Leviton Quickport RJ45 connections on rack mounted patch panels.

Data circuits run in the risers must be clearly labeled to assure they will not be disturbed.

Data Riser

Data riser cable shall be made by six (6) multimode 50 micron fibers.

Standards for Communication Outlet Installation

All station wiring from the IDF to a communication outlet shall meet the AT&T (568B) wiring standard for category 6e cable specification.

All station wiring will be connected or punched down in numerical order in each MDF, IDF-1 or IDF-2.

Pair No. Color Combination
1 Blue/White & White/Blue
2 Orange/White & White/Orange
3 Green/White & White/Green
4 Brown/White & White/Brown

The four unshielded pairs (1 through 4) will be terminated on a Leviton Quickport RJ45 in a faceplate or leviton surface mount receptacle at the station and on a Leviton Quickport RJ45 in a leviton rack monut patch panel using AT&T (568B) wiring standard.

RJ45 terminations must be made to campus standard patch panels. Wire jack connections shall be permanently marked on both ends of the wire, room jack, and RJ45 patch panel with the same non-duplicated number.

All station wire must be home run from the station to the nearest serving IDF on the same floor. All station wire and cables must be permanently marked on the cable and the face plate, jack or jack field with the same number on both ends.

The standard telecommunication outlet provides access to all available communication media. It will always contain at least two modular RJ45 receptacles.

Each communication outlet (equipped or wired for) shall require one duplex outlet in addition to present design requirements just to accommodate the need to "plug in" electronic equipment. Communications outlets will be spaced no further than 10 foot apart around the perimeter of each room where possible. All outlets will have conduit from a single gang box to an accessible ceiling or wire tray.

Communication outlets for campus wireless access points will be provided for a minimum of one in each classroom, conference room or room designed for meeting with more than 2 people. Communications outlets for campus wireless access will also be provided at a minimum of one every 1000 square foot of floor space. Communications outlets for access points will be provided at a standard height on walls normally used for emergency lighting. 

Any new or room renovations will include all infrastructure needed to add the new CAT 6e station cables, access points, switch and fiber infrastructure to existing campus managed systems. This additional equipment and infrastructure will be part of any renovation or construction project.

In any renovation and new construction projects where the IDFs are not stacked, the contract for electrical work shall include requirements for installation of two (2) riser conduits (4" minimum diameter) from the IDF-1 to each IDF-2. Junction or "pull" boxes shall be provided in each conduit run having more then two (2) 90 degree turns.
