  • Patent number: 6678377
    Abstract: The invention relates to a monolithically integrated telephone circuit for driving wide-band telephone lines and transmitting digital data at a very high frequency. The telephone circuit is powered from a battery DC supply providing a pair of voltage references. The telephone circuit includes an output circuit portion including a pair of differential output stages, each having a pair of inputs and being connected with its output to a respective lead of a two-wire telephone line. The telephone circuit also includes a device for deriving a reference voltage from the supply voltage, and includes a low-voltage supply network which is input a DC signal and produces a voltage reference to be added to the reference voltage for delivery to one input of each output stage. The other input of each stage receives an AC signal in order to present at the circuit output a suitable AC+DC differential voltage for driving the telephone line.

  • Patent number: 5596637
    Abstract: A circuit for limiting power dissipation through telephone subscriber line power supply interface devices, by using a pair of final stages to which an external component effective to dissipate power is connected. By use of separate discrete reference circuits, the presence of excessive common mode current is detected; and when this occurs, current to the driver stages is controlled at a lower magnitude.

  • Patent number: 5519775
    Abstract: A protection device, for a telephone (or other load) 27 in series with an external protection transistor 2, includes a sensor 6 for detecting common-mode current into the load. The output of the sensor 6 is connected to affect a current source/sink combination, and imbalance in this source/sink combination produces a voltage shift which is indirectly connected to control the protection transistor.

  • Patent number: 4797917
    Abstract: A telephone circuit, which may be monolithically integrated, for supplying ringing signals to a subscriber's line and for detecting an off the hook condition during ringing includes a circuit for supplying ringing signals coupled to exchange control components for generating a constant frequency sinusoidal signal which gives rise to the ringing signals and an enabling circuit, controlled by the exchange components, for enabling the supplying of the ringing signals to the line and for activating a circuit for detecting a direct current on the line. The circuit for detecting a direct current on the line supplies a signal to a circuit for controlling the detection of an off the hook condition, and which supplies an inhibiting signal for the enabling circuit and check, only after a predetermined time, whether the circuit for detecting a direct current on the line is still supplying a signal and for generating a signal informing the exchange components that the set has been off the hook.

  • Patent number: 4720852
    Abstract: A telephone circuit which may be monolithically integrated for generating control signals for displaying the telephone charges to a subscriber is coupled to an AC voltage signal generator of having a predetermined amplitude and frequency which are constant over time. The circuit includes a voltage generator for generating signals which are spaced over time and have a trapezoidal pulse waveshape. A multiplier circuit calculates the product of the signals supplied from the two voltage generators and supplies a signal which is sent to the speech circuit of the subscriber's line and is added to the speech signals. The trapezoidal pulse generator has a capacitor which is charged and discharged by a voltage to current converter of a non-linear type which is driven by exchange control components. The voltage across this capacitor forms the trapezoidal signals supplied by the generator.
