A management system for a partitioned multi-bandwidth communications network, i.e., a network in which end users are allocated virtual networks of limited bandwidth residing on lines of larger bandwidth. The management system includes a central management computer for use by network operators in communication with local terminals for use by end users. Tasks such as configurations for new circuits may be requested by the central operators as well as by the end users. Such requests are specified in terms of abstract logical objects, and the management system is programmed to correlate these logical objects to actual physical devices that comprise the circuit. The correlation programming is bi-directional so that in the case of a task such as failure detection, the management system may automatically correlate a failed physical object to a logical object for replacement.
