  • Patent number: 6717960
    Abstract: A method for reconstructing an aggregate stream of cells transmitted over communication links in an asynchronous transfer mode protocol includes determining a respective link delay for each of the communication links, including determining a fastest communication link. A common starting cell at which the cells from the communication links will correspond in time is determined based upon the fastest communication link. The method further includes filling a respective delay compensation buffer with corresponding cells for each of the communication links beginning with the common starting cell. The cells are read from the delay compensation buffers in a round-robin fashion to reconstruct the aggregate stream of cells.

  • Patent number: 6317494
    Abstract: A codec which normally provides impedance synthesis, filtering, suppression of receive signal echoes, and gain equalization for a plurality of line circuits under the control of a microprocessor includes an arrangement for ascertaining the actual impedance of each line that it serves and making a corresponding adjustment of the receive and transmit equalizers and other codec parameters. A series of short tones having precisely known amplitude frequencies throughout the voice band are applied to the line when the line is on-hook and during the off-hook interval before tone is returned to the subscriber. Impedance is measured by observing the echo and obtaining an estimate of the phase by performing a least squares fit during a time interval not exceeding the usual interdigital call signaling interval.

  • Patent number: 6263074
    Abstract: A user-programmable bass/treble control circuit is embedded within a conventional remotely located codec. A subscriber station set is capable of transmitting out-of-voiceband “control” tones to increase/decrease bass and treble. A tone detector within the codec recognizes and removes these control tones, forwarding them to a programmable equalization filter inserted in the transmit signal path in the codec. The equalization filter will adjust the bass and treble of the to-be-transmitted signal in accordance with these received control tones. Advantageously, the “listener” at the other end will not hear the tones if the tone detector is inserted before the receiver. The user may adjust the tones during the entire conversation and the filter may be “reset” at call completion.

  • Patent number: 5790072
    Abstract: A multi-channel integrated circuit, which includes N processing channels and a functional circuit which is time-shared between each of the N channels for processing data in accordance with a first clock strobe. Also included is a time-division multiplexed bus for providing synchronized data to and receiving synchronized data from said circuit in accordance with a second clock strobe. The data are thereby processed within said shared circuit in synchronization with said first and second clock strobes.
