Filed:

Oct 24, 1986

Appl. No.:

6/922685

Inventors:

Steven B. Perry - Highlands NJ

Assignee:

Keptel, Inc. - Ocean NJ

International Classification:

H04M 1300
H04M 322

US Classification:

379183

Abstract:

A circuit for connection into a telephone line for detecting when a telephone instrument has gone off-hook and which is unaffected by the presence of a ringing signal on the telephone line. The circuit comprises a transistor switch, a first plurality of series connected diodes connected in series with the telephone line for developing a first voltage thereacross when the telephone instrument has gone off-hook, an RC circuit coupled to the first plurality of diodes for charging to the first voltage when the telephone instrument has gone off-hook after a time delay and for activating the switch, a second plurality of series connected diodes, the second plurality being greater than the first plurality, the second plurality of diodes being connected to the switch and to the first plurality of diodes for developing a second voltage thereacross during one half cycle of a ringing signal on the telephone line. The first plurality of diodes develops the first voltage during a second half cycle of the ringing signal on the telephone line. The first and second voltages are of opposite polarity, such that the charging circuit alternately charges toward the first and second voltages during a ringing signal.

Keptel, Inc. - Ocean NJ

International Classification:

H04B 346

US Classification:

179 81R

Abstract:

Apparatus is disclosed for disconnecting and reconnecting equipment to a telephone line in response to at least one signal sent over the telephone line. The apparatus includes a voltage threshold circuit, a voltage regulator circuit, a current chargeable element such as a capacitor, a discharge circuit, a switch and a switch control. The switch is coupled to the telephone line and to the equipment and disconnects the equipment from the line in response to the signal sent over the line. The threshold circuit is coupled to the line and receives the signal. It provides an output signal to the regulator circuit only when the signal on the line exceeds a threshold voltage level. The voltage regulator circuit regulates the voltage at the output of the threshold circuit and provides a substantially constant voltage to the chargeable element. Since the voltage applied to the chargeable element is known, the time required to charge the chargeable element can be precisely determined. The chargeable element is coupled to the discharge circuit which causes the chargeable element to discharge when the signal to the threshold circuit falls below the threshold value, for example, when the signal is removed.

International Classification:

H04M 1300

US Classification:

379181

Abstract:

An apparatus and method for decoding ringing signals on a party telephone line coupled to the telephone line and a telephone instrument, according to the polarity of a d. c. voltage level present across the telephone line upon which ringing signals are superimposed and according to the grounded state of the telephone line. The apparatus comprises a discrimination circuit which supplies a selected one of the ringing signals to the telephone instrument via a ringing signal path to actuate the ringer of the telephone instrument. The apparatus further comprises a ringing signal rectification circuit connected to the telephone instrument via a voice signal path for preventing the ringing signal present on the telephone line from activating a ringer of the telephone instrument via the voice signal path. A switching circuit selectively connects the telephone instrument to the ringing signal path and the voice signal path. The apparatus further preferably comprises a circuit for eliminating bell taps and a balancing circuit for balancing the impedance across telephone line when the d. c.

International Classification:

H04M 1534

US Classification:

379102

Abstract:

Apparatus for disconnecting and reconnecting equipment to a telephone line in response to a signal sent over the telephone line. The apparatus includes a voltage threshold circuit, a voltage regulator circuit and a switching and timing circuit. The switching and timing circuit includes a first energy storage capacitor and a first discharge circuit. The switching and timing circuit further includes a second energy storage capacitor and a second discharge circuit and further includes a third energy storage capacitor and timing resistor. The first discharge circuit includes a first semiconductor switching device and a relay coil of a latching relay. The second discharge circuit includes a second semiconductor switching device and a second relay coil of the latching relay. When a signal is sent over the telephone line which exceeds the threshold level, it is regulated by the voltage regulator and charges up the first, second and third storage capacitors in an order such that the third capacitor charges first, the second capacitor next and the first capacitor last. Once the signal disappears from the telephone line, the first storage capacitor discharges into the first discharge circuit, thereby placing the switch into a first switching state and disconnecting the customer equipment.
