A functional block that communicates with a telecommunications management network (TMN) for the purpose of being monitored, or controlled, or both. [T1.210-1993]

A building (such as a central office) or nonbuilding location housing NEs. Communication within an NE location may be accomplished with minimal attention to such factors as noise, lightning protection, or the cost of bandwidth; communication outside an NE location uses suitable modems and uses conventional communications services or an EOC (embedded operations channel). [T1.204-1992]

1. In telephony, the discipline concerned with (a) determining internetworking service requirements for switched networks, and (b) developing and implementing hardware and software to meet them.
2. In computer science, the discipline of hardware and software engineering to accomplish the design goals of a computer network.
3. In radio communications, the discipline concerned with developing network topologies.
