Some important concepts and techniques related to dynamic operation and maintenance (O&M) systems for switching networks are demonstrated. Five types of node that comprise the dynamic network O&M system being developed by the authors are discussed. They are local exchanges, a centralized operation system, a database system, a diagnostics expert system, and maintenance workstations. The nodes are implemented on an efficient distributed system and use a standardized interface. This O&M system, which is geared toward improved maintenance, focuses on the switching network as a whole, rather than on individual exchanges. In the case of alarms and fault messages, O&M takes corrective action automatically.<>
