Paper Abstract

The telecommunications industry has been in place in the US for over a century. The network needed to sustain the industry has evolved through several paths to be a good workable network. A new Synchronous Optical Network SONET is being defined to bring the best parts of the network together into one consistent set. Several features are provided which make maintenance part of the network rather than a separate entity. The maintenance features of SONET, taken together, provide new possibilities in unified maintenance philosophy. The set of these features will be referred to in the following discussion as a Continuous In-Service Virtual Loopback (CIVL). The key to this philosophy is the built-in non-blocking use of overhead to administer and maintain a network. The following discussion has been limited to the first level SONET signal. It has also been limited to a relatively narrow set of simple network examples. The principles can and should be expanded as work proceeds toward the implementation of the network.
