Inter-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 install for backbone applications.
Backbone cable design shall follow all BICSI TDMM design recommendations and TIA568B standards. University at Albany must approve all final design in writing. A detailed T1 and Backbone logical drawings will be required for all Backbone cabling Plans, for more information on drawing detail see BICSI TDMM 9th Edition.
General The following will describe the minimum work area outlet requirements for area 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 must be approved in writing by University at Albany prior to design completion.
Any deviation from this shall require written approval from the University at Albany Project Manager.
Backbone cable design shall follow all BICSI TDMM design recommendations and TIA568B standards. University at Albany must approve all final design in writing. Detailed T2 drawings will be required for all Cabling Plans, for more information on drawing detail see BICSI TDMM 9th Edition.
In general, install one network 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 then 12'-0" from a network outlet. This rule is intended to keep the network station cord from exceeding the maximum length of 16'-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 area outlet. If more then 2 data cables are installed at a single work area outlet location, add duplex electrical outlets in the same proportion.
Standard 8'x10' office Each office shall have a minimum of two (2) work area outlets, one on each wall perpendicular to the door wall. The work area outlets should be three (3) feet from the back wall (furthest from the door).
Classroom Each classroom shall have a minimum of two (2) work area outlets and one wall phone outlet. One (1) of the work area outlets shall be a coax drop. The wall phone outlet shall be in the front of the room near the door. The remaining outlet will be located on the wall opposite of the front of the classroom.
Conference room Each conference room shall have a minimum of two (2) work area outlets. One (1) of the work area outlets shall be a coax drop. Location shall be determined on a case-by-case basis.
Special locations Computer rooms, labs, shared workspaces and other such areas must be reviewed on an individual basis for the quantity and types of work area outlets required.
Student Living Spaces
General
Living Area / Living Room Each living area or room shall have a minimum of one 1 (one) coax cable located perpendicular to and 3 feet from the front window.
Payphones and kitchen phones are not used in University at Albany residence halls.
Bedroom There shall be 1 (one) coax outlet for each bed. Location shall be determined on a case-by-case basis.
Open, Lounge, Common and other areas Locations and quantities will be designed on a case-by-case basis.
