  • Central office interface techniques for digital subscriber lines
    Patent number: 6760433
    Abstract: Techniques for interfacing a telephone line and central office equipment of a network operator providing and digital subscriber line data services are disclosed. The interface is splitterless in that no conventional bulky splitter is required. A SLIC independent, impedance synthesis network provide compensation for impedance imbalance caused by capacitor coupled across two-wire interface of voice circuit.
    Type: Grant

  • Ring trip detector
    Patent number: 6094480
    Abstract: A ring trip detector has a voltage difference detector with first and second inputs, for supplying an off-hook signal upon detection of a voltage difference. The ring trip detector also has a switch extending between the first and second inputs of the voltage difference detector. The ring trip detector detects when a telephone current starts to flow through a sensing resistor having first and second ends and to a telephone set. The switch closes upon an initial current flow through the sensing resistor and then opens. The ring trip detector has a pulse generating mechanism having two inputs respectively connected to the first and second ends of the sensing resistor. The pulse generating mechanism has an output and generates a pulse at the output when current starts to flow through the sensing resistor. The switch has a trigger connected to the output of the pulse generating mechanism for closing the switch when the pulse is generated. A differentiator mechanism may be used as the pulse generating mechanism.
