Abstract
In case of a disaster at one of a plurality of customer's locations, it is desirable to provide for a massive rerouting of telephone calls to that customer. A SafetyNet Service Reconfiguration (SSR) tool enables a network service provider to provide a recovery service for the event where a customer's business location becomes 'non-functional'. By using the SSR tool, the telephone network service provider can preplan how to reroute a customer's incoming calls to alternate business locations, or to the employees' homes. The preplanning includes storing the local central office recent change (RC) messages necessary to implement an SSR plan, in RC text files and in executable data files. The RC text files can be easily maintained, and new RC executable files generated, as the customer's recovery needs change. To invoke an SSR plan, the network service provider starts execution of the designated RC executable file, via a single SSR tool command. When the SSR plan is invoked, the data from the RC executable file is activated, thereby rerouting the traffic.
