Abstract: A unified and automated system for providing, restoring and optimizing special services is continually aware of the state of all the equipment and facilities in the network. The unified system responds automatically to a request for a special service by 1) designing a circuit required to support the requested special service, 2) identifying network facilities and configurations for implementing the designed circuit, 3) assigning those facilities to the circuit, 4) causing the various equipment providing the facilities to be interconnected to implement the service, 5) verifying the integrity of the special service, and 6) delivering the service to the customer.
