In residential telecom installation, what is the central distribution equipment called?

• A. Main distribution frame
• B. Central office
• C. Service terminal
• D. Head end

Answer: (D)

In telecom networks, the central distribution point that originates and routes signals to the internal wiring is called the head end. It serves as the hub where signals from the service provider are prepared for distribution to every outlet in the home, often through splitters and amplifiers that ensure coverage to all rooms. The other terms refer to different parts of the system: a main distribution frame is a cross-connect panel used in larger facilities to tie together outside lines with inside wiring; a central office is the service provider’s main switching facility; a service terminal is typically the demarcation point or termination for customer equipment. Within a residential installation, the head end best describes the central distribution equipment that distributes signals throughout the home.
