    Abstract: A satellite transponder switch (STS) maintains a table that maps set-top boxes (STBs) to carrier frequencies. The STS receives a first request from a first STB for a first transponder band and a second request from a second STB for a second transponder band. The STS accesses a first satellite feed and polarity based on the first request, and a second satellite feed and polarity based on the second request. The STS band-pass filters the first and second transponder bands from the first and second satellite feed and polarity, respectively. The STS frequency shifts the first transponder band to a first carrier frequency assigned to the first STB and the second transponder band to a second carrier frequency assigned to the second STB. The STS outputs a signal that comprises the frequency-shifted first and second transponder bands to the first STB and the second STB.

    Abstract: The present invention relates to a method and apparatus for selectively enabling and disabling transmit and receive functions of a radio (figure 1A), and more particularly to a system and method utilizing an out-of-band signal over a time division duplex channel to control transmit (11) and receive (12) functions of a radio so as to synchronize with the functions of a remote modem (figure 2, 40). The invention relates to a system and method for synchronizing the transmit and receive modes of a radio via an out of band signal. The out of band signal is preferably a control tone at a predetermined frequency and is substantially coextensive with the communication signal to be transmitted. The radio filters a multiplexed signal and detects if the control tone is present. If the control tone is not detected, the radio preferably remains in the default receive mode. If the control tone is detected, the radio operates in the transmit mode for the duration of the control signal.

    Abstract: A system and method of compensating for path losses for data transmissions from various remote modems (408) to a central modem (332) for use in a system that provides data communications over a passive multipoint network such as coaxial tree and branch cable television distribution network (320). The central modem (332) communicates to remote modems (408). The remote modems can be placed in communication with a downstream device (such as a personal computer) (420) to allow the downstream device (420) to communicate with the central modem and ultimately with a wide area network such as the Internet (504).
