Which term refers to the end point in the network where customer lines terminate for interconnection to trunks?

• A. Local Loop
• B. TSP
• C. End Office
• D. Facility

Answer: (C)

This describes the endpoint in the network where customer lines terminate to interconnect with trunk circuits. In traditional telephone networks, the end office (often called the central office) is the local switching center where the subscriber’s local loop ends and from which trunk lines to other offices begin. It houses the switching equipment that routes calls to destinations beyond the local area and provides the interface to long-distance and interoffice networks. Understanding the local loop helps: the local loop is the physical copper or fiber link from the customer premises to the network, but it ends at the end office. The term TSP refers to a transit or switching point in some contexts, not the endpoint where customer lines terminate for trunk interconnection. A facility is too generic and could refer to many different network components, not specifically the endpoint for subscriber interconnection to trunks.
