  • Call traffic based exception generating system
    Patent number: 5809491
    Abstract: A system for generating an exception report for a particular problem based on call traffic. The system maintains a count of occurrences for that problem, happening within a sliding window of call traffic volume. When the count exceeds a threshold value, the system generates the exception report whereby appropriate action may be initiated to correct the problem.

  • Pulse rejection and duration correction circuit
    Patent number: 4266099
    Abstract: A circuit which is particularly adapted for reconstructing fixed time duration dialing pulses in a telephone communications system while rejecting spurious pulses of less than a selected pulse duration. The circuit utilizes two coupling networks having integrated outputs of opposite polarity which are summed after passing through two separate switching amplifiers. The summed outputs are fed through a third switching amplifier having a hysteresis characteristic so that it switches only when both outputs have switched to the same polarity.
