摘要：
An example involves assigning a first logical circuit identifier to a logical failover circuit prior to a failure of a dedicated logical circuit. The dedicated logical circuit includes first variable communication paths to route data through a first local access and transport area (LATA), second variable communication paths to route the data through a second LATA, and fixed communication paths to route the data between the first LATA, the second LATA, and an inter-exchange carrier. The failure of the dedicated logical circuit is identified based on status information pertinent to the dedicated logical circuit. The logical failover circuit includes an alternate communication path for communicating the data. When the first logical circuit identifier does not match the second logical circuit identifier, the second logical circuit identifier is renamed to match the first logical circuit identifier. The data is rerouted to the logical failover circuit without manual intervention.
