RCDD · Question #263

Buildings larger than ________ must contain a dedicated room for the termination of entrance facilities.

The correct answer is C. 9300 square m (100,000 square ft). Per BICSI TDMM and TIA-569, buildings larger than 9300 sq m (100,000 sq ft) must have a dedicated entrance room (ER) for terminating entrance facilities rather than sharing space with other functions.

Why each option

Per BICSI TDMM and TIA-569, buildings larger than 9300 sq m (100,000 sq ft) must have a dedicated entrance room (ER) for terminating entrance facilities rather than sharing space with other functions.

A5529 square m (60,000 square ft)

5529 sq m (60,000 sq ft) is below the recognized threshold and does not trigger the dedicated entrance room requirement under BICSI standards.

B7389 square m (80,000 square ft)

7389 sq m (80,000 sq ft) is also below the 100,000 sq ft threshold specified in BICSI TDMM.

C9300 square m (100,000 square ft)Correct

The 9300 sq m (100,000 sq ft) threshold is the BICSI-defined building size above which a dedicated entrance room is mandated for entrance facility terminations. Below this threshold, an entrance facility can be co-located within another telecommunications space, but larger buildings generate enough incoming cabling and pathway density to require a separate, secured room.

D11,160 square m (120,000 square ft)

11,160 sq m (120,000 sq ft) sets the bar too high and would exempt buildings that actually do require a dedicated entrance room.

E13,300 square m (140,000 square ft)

13,300 sq m (140,000 sq ft) is well above the correct threshold and is not referenced as a design breakpoint in BICSI or TIA-569.
