  • Patent number: 5276678
    Abstract: A communication system having full call processing capabilities in the user ports, each port being connected to a TDM collection bus and a TDM distribution bus. A bus controller terminates the collection bus on which voice words are deposited in time slots by the respective user ports, the voice words being realigned and transmitted by the bus controller on the TDM distribution bus. Each user port is assigned a time slot and can thus communicated simultaneously with one or more other user ports, such as during a two-way telephone conversation or a multiple party conference call. A memory in each user port combines plural voice words obtained from respective TDM time slots of conference participants, and combines such voice words into a composite signal representative of all the other conferees. The conference circuit of each user port combines the voice words of all the other participating ports over a frame period, except its own voice word, and thus the composite voice word of each user port is different.

  • Patent number: 4490582
    Abstract: There is disclosed a speakerphone circuit employing precision peak detectors in which the processing of talk down signals and switch guard signals is partitioned in order to accurately control complementary switched gain in the transmit and receive channels to achieve improved sensitivity to talk down switching action by setting a low switching threshold.

  • Patent number: 4385207
    Abstract: A line powered loudspeaking telephone is implemented entirely from electronic components, eliminating inductors and transformers. A three stage (521, 523, 525, 532) output amplifier is used with the loudspeaker impedance forming the output stage impedance. A feedback network (527, 528, 529, 530) is used between the amplifier input and output stages to provide the desired gain at audio frequencies while forcing the DC gain to unity. The circuit then functions to provide proper gain for audio frequency signals received from the communication line while reflecting onto the communication line the resistive component of the output stage impedance scaled by biasing circuit elements (518, 519) of the amplifier input stage, thereby maintaining the proper voltage-current characteristic of the communication line.
