    摘要： A cable network system for bidirectionally communicating signals at an enhanced duplex frequency range, which may be between about 5 MHz and about 650 MHz. This system may include a first amplifier, which may be configured to condition an upstream signal proceeding from a subscriber premises to a headend, without necessarily conditioning a downstream signal proceeding from the headend to the subscriber premises, a second amplifier, which may be configured to condition the downstream signal without necessarily conditioning the upstream signal, and a shaping circuit, which may condition the upstream and downstream signals. This system also may simultaneously, or in an overlapping or offset manner, communicate signals at a full duplex frequency range without a diplex filter.

    摘要： Aspects of the subject disclosure may include, for example, a repeater device having a first coupler to extract downstream channel signals from first guided electromagnetic waves bound to a transmission medium of a guided wave communication system. An amplifier amplifies the downstream channel signals to generate amplified downstream channel signals. A channel selection filter selects one or more of the amplified downstream channel signals to wirelessly transmit to the at least one client device via an antenna. A second coupler guides the amplified downstream channel signals to the transmission medium of the guided wave communication system to propagate as second guided electromagnetic waves. Other embodiments are disclosed.

    摘要： A communication system has a plurality of stations which communicate data in a data frame having a plurality of slots, wherein the plurality of slots are new message minislots NMS, expansion minislots EMS, and data slots DS. A master station determines a range parameter R which is based upon a number of slave stations transmitting reservation requests in a data frame. The master station also determines a parameter MAP according to a number of reservation requests in a queue waiting to be processed by the master station. The parameter MAP defines the new message minislots, the expansion minislots, and the data slots in an upstream data frame. The master station transmits the range parameter R and the parameter MAP to a plurality of slave stations. Each slave station independently determines a random transmission parameter RN. Each slave station transmits to the master station (i) a new reservation request in a new message minislot if its random transmission parameter RN corresponds to the parameter MAP, (ii) an old reservation request in an expansion minislot if assigned an expansion minislot in the parameter MAP, and (iii) data in a data slot if assigned a data slot by the master station.

    摘要： A time-sharing subscriber communications system wherein a timedivision multiplexed signal having a series of frames and a predetermined number of time slots in each frame is transmitted in a given frequency band over a single wideband circuit to a plurality of subscriber terminals. Various time slots contain information from various input channels which are respectively related to various ones of the subscriber terminals. The transmitted signal is modulated by a zero axis crossing modulation scheme wherein each time slot is defined by the interval between successive zero axis crossings and the information contained in each time slot is defined by the duration of the time slot. At each subscriber terminal the information related to that channel is tapped off from the signal received from the transmitter terminal, a portion of the received signal is retransmitted over the wideband circuit and new information related to the subscriber terminal is newly transmitted in one or more time slots of each frame of the timedivision multiplexed signal. A receiver terminal, interfaced to the opposite end of the wideband circuit from the transmitter terminal, demodulates the newly transmitted information from the subscriber terminal and provides output signals to various output channels respectively related to various ones of the subscriber terminals.

    摘要： A two-way two-wire repeater is disclosed comprising two oppositely directed amplifiers coupled to a transmission line. The repeater is provided with a series capacitor and diode connected to feed a portion of the signal at the output of a stage of one amplifier to the input of a stage of the oppositely directed amplifier. This feed-across path eliminates the need for ''''hybrid coil'''' coupling by deforming amplifier oscillation into pulses and permitting the pulses to be amplitude or height modulated.
