  • Traffic monitor for detecting trunk traffic congestion in a telephone switching network
    Patent number: 6567510
    Abstract: A traffic monitor listens passively on the data link used to communicate among switching systems for setting up telephone calls for call setup messages and checks the call setup messages for destination telephone number. If it determines that the destination telephone number is for an Internet service provider (ISP), the system reports the point code of the originating office. By analyzing the output of the traffic monitor according to this invention, local exchange carrier (LEC) may reconfigure its network to remove feature rich switches from the ISP call delivery network and replace them with a small tandem-like switch.
