271300 – COMMUNICATIONS BACKBONE CABLING                                                                                                        

Backbone cabling is the media over which Voice, Video, Data, Audio, Community antenna television (CATV) signals will be transmitted to the TR's. The media used for the transmission of the signals will be copper, fiber and coax.

Backbone cables are broken into two types, inter-building and intra-building.  Intra-building cabling has very strict requirements when entering a building. Cable insulation type, lightning protection and termination methods are important considerations when designing outside plant (OSP) cabling. 

Sizing of backbone cabling for support of a building is directly related to the building's functions both during initial occupancy and future use. There is no generic backbone installation that will fit all applications. Design of the building's backbone cabling will be on a case-by-case basis. Generally, Optical Fiber, High Pair Count Copper and Coaxial cable will be installed for backbone applications.

Backbone cable design shall follow all BICSI TDMM design recommendations and TIA568C standards. Wright State University shall approve all backbone infrastructure designs in writing prior to design completion.

A transition point will be required when outside cable plant enters a building. This location will need to be accessible to future access and construction activities. Refer to TIA568C and confirm the location and needs of this access point with the University.

271500 – COMMUNICATIONS HORIZONTAL CABLING                                                                                                    

The following will describe the minimum work area outlet requirements for areas such as, a standard 8’x10’ office, classroom and conference room, special locations and residents halls. The exact placement and quantities of outlets and pathways shall be approved in writing by Wright State University prior to design completion. Any deviation from this shall require written approval from the University.

Horizontal cable design shall follow all BICSI TDMM design recommendations, TIA568C and TIA569C standards. Wright State University shall approve all final designs in writing.

In general, install one work station drop on each wall measuring 12'-0" in linear length. Provide additional work area outlets as required so that no "point" along the liner wall space is more than 12'-0" from a network outlet. This rule is intended to keep the network station cord from exceeding the maximum length of 10'-0" from the wall outlet to the network device.

A minimum of one duplex electrical outlet shall be installed within 16", but not closer than 8", of every work station location.

Standard office
Each office shall have a minimum of two (2) work station locations, one on each wall perpendicular to the wall that has the door in it. The work station locations should be three (3) feet from the back wall (the wall opposite from the wall with the door in it).

Classroom
Each classroom designed will vary on a case by case basis.

As a typical installation requirement. Refer to the audio visual requirements and add these notes; 

• Conduits for data cabling to be 1-1/4”.
• Wall phone location 48” AFF with 4” square box 2 1/8” deep with a single-gang mud ring and 1-1/4” conduit to cable tray.
• Preferred floor box is FSR FL-2000 series. Contractor shall coordinate divider & conduit layout into floor box with WSU prior to installation.

Conference room
Each conference room shall have a minimum of two (2) work area outlets. Location shall be determined on a case-by-case basis. Confer with the university for conferencing, or overhead projector applications.

Special locations
Computer rooms, labs, auditoriums, shared workspaces, and other such areas must be reviewed on an individual basis for the quantity and types of work area outlets required.

Wireless Access Point (WAP)
All wireless access point (WAP) locations shall be determined by Wright State University CaTS department and shall be done so on a case by case basis for every project. At a minimum a 1-1/4” conduit shall be installed from the cable tray to the prescribed WAP location where a 5” X 5” box shall be installed with a 2 gang mud ring flush with the ceiling.

All equipment that requires WSU network or telephone connectivity such as Siemens automation panels, Square

D power meters, Elevator control panels, Generator ATS’s, etc. shall have a 1” conduit run from the device to the nearest cable tray.

Conduits can be terminated at or in the device if there is no exposure to electrical hazards otherwise a 4” square 2 1/8’ deep box will be installed inline within 4’ of the devices where cabling can be terminated & accessed safely for maintenance & testing purposes.
