Abstract
The method enables a set of services to be maintained within a private communications network even in the event of the network becoming split. It uses emergency means providing dynamic accesses that are previously defined by the user of the network. The dynamic accesses serve to carry signaling signals. Calls are routed using a method of routing that is both static and predetermined, imposing a path that is predetermined before a fault occurs, thereby making it possible for the network to react more quickly once it detects faulty operation.
