Cable backbone distances have traditionally been associated with application specific distance limitations e.g., 10Base5 (500m). The survey is intended to characterize cable distances based on the physical plant, the number and area of floors in a building, and the distance between buildings in a campus. Cable Reference Model key TO = Telecommunication outlet ER = Equipment Room TC = Telecommunication Closet WA = Work Area TP = Transition Point 2 Definitions The survey cable definitions are in reference to the illustration [1] in Figure 1. The definitions are consistent with TIA/EIA-568A- Commercial Building Telecommunications cable Standard and TIA/EIA-569-Commercial Building Standard for Telecommunications Pathways and Spaces. Campus- the buildings and grounds of a complex; e.g., a University, industrial park, military base. Commercial Building- a building or portion thereof, that is intended for office use. Telecommunications Equipment Room- a centralized space for telecom- munication equipment that serves the occupants of the building. An equipment room is distinguished from the telecommunications closet by the nature of the complexity of the equipment. Telecommunications Closet - an enclosed space for housing telecommu- nications equipment, cable terminations, and cross-connect cable. Thecloset is the recognized location of the cross-connect between the backbone and the horizontal facilities. Horizontal cable - the cable between the telecommunication outlet and the telecommunications closet Backbone cable - cable between the telecommunications closets and the equipment rooms within or between buildings. Interbuilding Backbone cable - Backbone cable between buildings. Intrabuilding Backbone cable - Backbone cable within buildings. ________________________________________________________________ [1] TIA/EIA-569 recommends Telecommunication closets placement be close as practicable to the center of the area served 3 Survey Questionnaire 3.1 Building Profile ___________________________________________________________________ Table 2: Building Plan ___________________________________________________________________ Typical number of floor(s) [____] to [____], exam- ple [1] to [3] Typical number of telecommunications out- [____] to [____], exam- lets per floor ple [25] to [200] Typical number of telecommunications Clos- [____] to [____], exam- ets per floor ple [1] to [4] ___________________________________________________________________ Floor Area ___________________________________________________________________ less than 10,000 square feet [_______%] between 10,000 square feet and 40,000 square feet [_______%] greater than 40,000 square feet [_______%] ___________________________________________________________________ Table 3: Building Occupancy ___________________________________________________________________ Building Occupancy : Percentage of Installations ___________________________________________________________________ Business [_______%] Manufacturing [_______%] Hospital [_______%] Educational [_______%] Rental Property [_______%] Military [_______%] Multi-tenant Buildings [_______%] Other_________________ [_______%] 3.2 Intrabuilding Backbone and Horizontal cable Distances Horizontal cable (Table 4) distance is the cable between the telecom- munication outlet and the telecommunications closet as illustrated in Figure 1.
