SONET-New technology with new management requirements
R. Holter · 2003
Synchronous optical network (SONET) and synchronous digital hierarchy (SDH), two standards activities that are providing the infrastructure for new telephony interfaces, are discussed. In addition, the telecommunications management network (TMN), which provides an architecture to support standard interfaces, functions, and messages to network management of telecommunication networks, is described. It is argued that the interpretation of these technologies and architectures requires an understanding of new requirements in managing telephone networks.>
