BICSI Certification BICSI Telecommunications Rooms and Spaces 2 — Questions and Answers
Question 1: In BICSI cabling hierarchy, what differentiates an 'Intermediate Cross-Connect' (ICC) from a 'Horizontal Cross-Connect' (HCC)?
- The ICC connects campus backbone cables between buildings; the HCC connects backbone and horizontal cabling within a building floor (Correct answer)
- The ICC handles fiber only; the HCC handles copper only
- The ICC is located outdoors; the HCC is located indoors
- The ICC supports higher bandwidth; the HCC supports lower bandwidth
Correct answer: The ICC connects campus backbone cables between buildings; the HCC connects backbone and horizontal cabling within a building floor
The ICC connects campus backbone cables between buildings or between building MCC and floor-level HCCs, while the HCC serves as the connection point for horizontal cabling on a given floor.
Question 2: What is the maximum allowable backbone cable length between an Intermediate Cross-Connect (ICC) and a Main Cross-Connect (MCC) for multimode fiber?
- 300 meters
- 500 meters
- 2,000 meters (Correct answer)
- 3,000 meters
Correct answer: 2,000 meters
ANSI/TIA-568 allows a maximum backbone cable length of 2,000 meters between the ICC and MCC for multimode fiber in campus environments.
Question 3: Which BICSI/TIA standard governs the design of telecommunications spaces specifically for commercial buildings?
- ANSI/TIA-568
- ANSI/TIA-569 (Correct answer)
- ANSI/TIA-606
- ANSI/TIA-607
Correct answer: ANSI/TIA-569
ANSI/TIA-569 (Commercial Building Standard for Telecommunications Pathways and Spaces) governs the design and construction of telecommunications spaces including rooms, conduits, and cable trays.
Question 4: What is the recommended loading capacity of a telecommunications room floor, per BICSI/TIA-569?
- 2.4 kPa (50 lb/ft²)
- 4.8 kPa (100 lb/ft²) (Correct answer)
- 7.2 kPa (150 lb/ft²)
- 12.0 kPa (250 lb/ft²)
Correct answer: 4.8 kPa (100 lb/ft²)
ANSI/TIA-569 recommends a minimum live floor loading capacity of 4.8 kPa (100 lb/ft²) for telecommunications rooms to support heavy equipment racks.
Question 5: Per BICSI guidelines, what is the recommended power outlet configuration for a telecommunications room with equipment racks?
- One 15A duplex outlet on a shared circuit
- Dedicated 20A circuits with multiple outlets at rack locations, plus a convenience outlet near the door (Correct answer)
- Power strips running from a single 30A circuit
- Only UPS-provided power outlets
Correct answer: Dedicated 20A circuits with multiple outlets at rack locations, plus a convenience outlet near the door
BICSI recommends dedicated 20A branch circuits with multiple outlets at each rack location plus a standard convenience outlet near the door for tools and test equipment.
Question 6: What is the purpose of an 'Entrance Facility' (EF) in a BICSI-compliant building cabling system?
- It provides the main power distribution for all telecommunications equipment
- It is the point where outside plant cabling enters the building and transitions to inside plant cabling (Correct answer)
- It serves as the central wiring closet for the entire building
- It is the demarcation point between two tenants' networks
Correct answer: It is the point where outside plant cabling enters the building and transitions to inside plant cabling
The Entrance Facility (EF) is the point where outside plant cabling enters the building and transitions to inside plant cabling, housing the network demarcation and protection equipment.
