  • Patent number: 5974459
    Abstract: A telecommunication network without a network management layer meets operational objectives by providing at least one hot standby system which replaces a malfunctioning element of a service-providing node in the event of any disruption in services. Each service-providing node includes n primary processors and k spare processors. The telecommunications network implements all layers of the Telecommunication Management Network (TMN) standard except for the network management layer. The system therefore implements the business managemen, service management, and element management layers. An operation administration and maintenance server monitors the network to detect a malfunctioning element of a service-providing network node. Upon detecting a fault, the operation administration and maintenance server sends an out of service message to a central network planning and operations center and/or notifies an on site work force of the probable trouble.
