ICT Today

60 I ICT TODAY provided when the floor area to be served exceeds 1000 m (10,000 ft); or the horizontal distribution distance to the work area exceeds 90 m (295 ft)." Both the com- mercial building and healthcare facility TR designs shall comply with TIA-569-D. The additional size for a health- care facility TR accommodates the additional systems and provides room for growth (see Figures 2, 3 and 4). Use the following guidelines when designing and planning TRs in healthcare facilities: • At least one TR must be included on each floor. • The TR must serve a maximum area of 20,000 sq. ft. (approx. 1,858 sq. m). • The TR dimensions must meet the requirements of the authority having jurisdiction (AHJ); if an AHJ is not present, then the minimum floor dimensions should be 12 ft. x 14 ft. (approx. 3.65 m x 4.27 m). • The TR must be planned to support a 50 percent growth factor of systems and services. • Consider limitations where certain medical and building systems cannot be located in the TR. In this case, the room must be dedicated for the use of ICT and related systems and not shared space with storage, maintenance, janitorial and other applications. • Working space in front and back of racks and cabinets should be at least 3 feet (1 meter). FIGURE 2: In a typical TR layout, the minimum floor space is 10 ft. x 10 ft. (approx. 3.04 m x 3.04 m) for every 10,000 sq. ft. (approx. 929.03 sq. m) of area. (Source: ANSI/BICSI 004-2018). FIGURE 3: Healthcare TRs must include sufficient space for specialty systems, such as nurse calls, biomedical devices, and patient monitoring. The minimum floor recommendation is 12 ft. x 14 ft. (approx. 3.65 m x 4.27 m) for every 20,000 sq. ft. (approx. 1,858 sq. m). (Source: ANSI/BICSI 004-2018). FIGURE 4: As an added challenge, certain hospitals will not allow medical or building systems to be included inside the TR. In this instance, a slip room design is required.

If used, PDSs should be located in common areas where they can be inspected on a regular basis for unauthorized access. Refer to ANSI/TIA-5017 for other measures that can be taken to improve the physical network security of telecommunications cabling infrastructure.
