    摘要: Described herein are a number of steps, methods and/or solutions that can be applied to greatly improve attenuation control of RF signals in cable plant. The present disclosure is directed to a cable modem auto-attenuation system or any other signal transferring system. The system may be capable of taking a high-power signal from the cable plant's service line, dropping the power value down to a usable level and transmitting the signal to a cable modem while eliminating the need for rigorous manual adjustments that a normal cable modem often requires. In certain embodiments, the system may be integrated into a separate device connected between the modem and the cable company service line and configured to handle upstream and downstream attenuation separately or jointly.

    摘要: A data receiver interface circuit is provided with a circuit for accepting correctly framed data. The plurality of data bits sandwiched between a pair of frame pulses is temporarily stored while the number of clock cycles occurring between the frame pulses is determined to be a valid number. The data is accepted by the receiver if the number of clock cycles occurring between the pair of successive frame pulses is a valid number.
