摘要： A distributed telephone communication system (50) interconnects telephone units (52) via a single transmission line (56) providing full duplex communication between any pair of telephones (52). Each telephone (52) is coupled to the transmission line (56) by a control unit (54) which pages other control units (54) to initiate a telephonic communication. Each control unit (54) has an identification number and circuitry (60) for recognizing the identification number contained within a paging signal so as to initiate a response. In a separate spectral portion of the transmission line (56), there are provided sets of analog communication channels each of which has upper and lower spectral portions to provide two-way communication in opposite directions between a pair of tehephones (52) engaged in communication. A transmitter (22) and a receiver (23) in each of the control units (54) is provided for the communication of analog signals of both voice and date via the voice channel. Each control unit (54) includes circuitry (1A, 1B) for tuning the transmitter (22) and the receiver (23) to the selected channel in accordance with digital data transmitted via a transmission line (56) and specifying a selected one of the voice channels.

摘要： Systems and methods for ranging adjustments are provided. In one embodiment, a remote service unit comprises: a transceiver communicatively coupled with a host in a multi-point to point configuration, the transceiver configured to communicate with the host via an OFDM waveform; and a multi-carrier modem coupled to the transceiver and configured to demodulate downstream information data from the OFDM waveform, the multi-carrier modem further configured to modulate upstream information data onto the OFDM waveform. The multi-carrier modem modulates upstream information data onto distinct subcarriers of the OFDM waveform, the multi-carrier modem synchronized with the host so that upstream OFDM signals transmitted by the transceiver and other upstream OFDM signals received at the host unit combine to a unified OFDM waveform. The multi-carrier modem adjusts a round trip path delay between the remote service unit and the host based on a path delay correction received from the host unit.
