Communications network class-of-service routing
 The routing of calls of different classes of services as well as the administration thereof is enhanced by associating each such class of service with a number of parameters common to such services, such that each class of service, as well as a new class of service, may be readily identified by its respective parameter values. Accordingly, the routing and administration of calls of different classes of services may be handled in a systematic, straight forward manner so that basic network capabilities may be made available to various services using an administratively defined menu like structure. In addition, such class of service advantageously partitions network bandwidth allocation, call routing priority, voice/data transport, and traffic data registers into respective classes of services.
