point-to-multipoint circuit - Computer Definition
A dedicated circuit that connects a single device (i.e., point) to multiple devices. A simple bridge connects the link from the primary device to the links that connect to each secondary device. Such a circuit is also known as a multi-drop circuit and a fantail circuit, as the circuit fans out like a tail from the headend. Point-to-multipoint circuits generally are phrased in the context of a wide area network (WAN), and generally are provided as a carrier service. As an example, Digital Data Service (DDS) circuits are configured as either point-to-point or point-to-multipoint. See Figure P-5. See also bridge, circuit, DDS, link, and point-to-point.
