The process of interconnecting two or more individual networks to facilitate communications among their respective nodes.
Note: The interconnected networks may be different types. Each network is distinct, with its own addresses, internal protocols, access methods, and administration.

Synonym isolated ground plane.

A signaling and media interconnection point between callers in legacy wireline/wireless originating networks and an NG9-1-1 Emergency Services Network. This Functional Element provides MF/SS7-to-SIP signaling interworking, as well as emergency services-specific processing.

The customer side of any digital subscriber line (DSL) that does not terminate on the customer installation (CI). [T1.216-1998]

See network topology.

A data communications system that (a) lies within a limited spatial area, (b) has a specific user group, (c) has a specific topology, and (d) is not a public switched telecommunications network, but may be connected to one.
Note 1: LANs are usually restricted to relatively small areas, such as rooms, buildings, ships, and aircraft.

A communication network within a TMN (telecommunications management network) that supports data communication functions (DCFs) normally at [specified] reference points q1 and q
2. LCNs range from the simple to the complex. LCN examples include point-to-point connections and networks based on star and bus topologies. [After T1.210-1993]

See network topology.

A data communications network that (a) covers an area larger than a campus area network and smaller than a wide area network (WAN), (b) interconnects two or more LANs, and (c) usually covers an entire metropolitan area, such as a large city and its suburbs.
