  • Management method for maintaining communications options within a private communications network
    Patent number: 7079484
    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.

  • Method of managing call collision in a D channel
    Publication number: 20010007566
    Abstract: In a method of managing call collisions, in the event of a bit rate collision or a logical channel collision occurring at the time of a request to set up a call between a first terminal and a second terminal, one terminal is designated the master terminal and the other terminal is designated the slave terminal. Depending on the source of the call request packets, the two calls are automatically transmitted via the signaling channel or a data channel.
