Question

Quizplus · Accepted Answer

A DSLAM (Digital Subscriber Line Access Multiplexer) is a device that aggregates multiple DSL subscriber lines and connects them to the carrier's central office (CO). DSLAMs are typically installed in telephone exchanges or remote terminals, and they allow carriers to offer high-speed broadband Internet and other services to their customers over existing copper telephone lines. Terminal adapters are used to connect analog devices to digital networks, smart jacks are used to provide diagnostic information and testing capabilities for T1 and other digital circuits, and terminators are used to terminate the end of a cable or wire. None of these devices perform the function of aggregating multiple DSL subscriber lines and connecting them to the carrier's CO, which is why the best choice is B) DSLAM.
