An access network is the part of a telecommunications network which connects subscribers to their immediate service provider. It is contrasted with the core network, (for example the Network Switching Subsystem in GSM) which connects local providers to each other. The access network may be further divided between feeder plant or distribution network, and drop plant or edge network.
