What is the term for a cable that connects the telecommunications room to the building entrance facility?

• A. Backbone Cable
• B. Riser Cable
• C. Premises Wiring
• D. Conduit Piston

Answer: (A)

Backbone cabling is the main high-capacity link that ties the key distribution points together, including the telecommunications room and the building entrance facility. This path carries data across longer distances and often between floors or separate parts of the building, forming the primary conduit for the internal network to reach the point where external service enters. Because the cable runs from the telecom room to the building entrance facility and serves as the central connective path, it fits the backbone category. Riser cable describes vertical runs between floors inside the building but not specifically the link to the entrance facility. Premises wiring is a broad term for all inside-building cabling, which doesn’t designate this particular high-capacity, long-distance connection. Conduit piston isn’t a recognized term in this context.
