In telecommunications networks, a node (Latin: nodus, ‘knot’) is either a redistribution point or a communication endpoint.
A physical network node is an electronic device that is attached to a network, and is capable of creating, receiving, or transmitting information over a communication channel.[1] In data communication, a physical network node may either be data communication equipment (such as a modem, hub, bridge or switch) or data terminal equipment (such as a digital telephone handset, a printer or a host computer).
A passive distribution point such as a distribution frame or patch panel is not a node.
