Abstract:
A telephone system comprising an analog telephone and a full-duplex speakerphone adapter is disclosed. The analog telephone comprises an ordinary analog telephone subscriber circuit for transmitting and receiving analog signals and a handset for users. The full-duplex speakerphone adapter is coupled between the analog telephone and a central office, uses a subscriber loop interface circuit through the first telephone line to couple to the ordinary analog telephone subscriber circuit of the analog telephone and uses a telephone hybrid interface circuit through the second telephone line to couple to a wall jack to communicate with the central office.
In a digital communications system with a time-division multiplexed medium having a transmit r. f. channel and a receive r. f. channel on an internal network having a head end multiplexer and interface for external connection of calls, timeslots are allocated to maximize time slot usage between internal calls and external calls by dynamically differentiating between internal call types and external call types, or calls between nodes within the internal network between an internal node on the internal network and an external node connected through a trunk, and, based on differentiation for the external call types, claiming a free timeslot for the internal node on the transmit r. f. channel and using the corresponding timeslot on the receive r. f. channel to establish communication between the internal node and the external node.

Abstract:
A baseband signal is spectrally efficiently transmitted on a broadband transmission medium by inserting gaps in packets of digital data transmitted in a modulated first radio frequency carrier. The transmitted packets of data are received by demodulating the modulated first radio frequency carrier, and the gap is monitored for the presence of digital data thus indicating a collision of simultaneously transmitted packets of digital data. A seed of arbitrary digital bits are used in scrambling each packet of digital data and is transmitted with the packet of data for use in descrambling the data. In retransmitting the packet of data the seed is included. The originally transmitting node receives the retransmitted packet and compares the retransmitted seed with the originally transmitted seed for detecting an error in retransmission.
