    摘要： An architecture for providing high-speed access over frequency-division multiplexed (FDM) channels allows transmission of ethernet frames and/or other data across a cable transmission network or other form of FDM transport. The architecture involves downstream and upstream FDM multiplexing techniques to allow contemporaneous, parallel communications across a plurality of frequency channels. Furthermore, the architecture allows a central concentrator to support a plurality of remote devices that each have guaranteed bandwidth through connection-oriented allocations of bi-directional data flows. The upstream and downstream bandwidth allocation can support symmetrical bandwidth as well as asymmetrical bandwidth in either direction. The architecture generally can be used to support connection-oriented physical layer connectivity between a remote device and the central concentrator. Furthermore, the architecture may be integrated into other higher level devices such as, but not limited to, bridges, switches, routers, and/or gateways. In addition, the architecture may be used as a local network such as the networks commonly called local area networks (LANs). As a local network, the architecture supports guaranteed bandwidth for delivery of data flows to a plurality of host devices. Each host device might have a network interface card (NIC) that conforms to the architecture of the preferred embodiments of the present invention. Moreover, because the architecture may peacefully coexist with other services commonly-found in cable distribution networks, these other services may also be delivered to a host device. Thus, as a non-limiting example a host device may utilize the preferred embodiments of the present invention for local area network (LAN) data communication, and may also utilize cable television video channels in the same communication medium to carry various multimedia information.

    摘要： An architecture for providing high-speed access over frequency-division multiplexed (FDM) channels allows transmission of ethernet frames and/or other data across a cable transmission network or other form of FDM transport. The architecture involves downstream and upstream FDM multiplexing techniques to allow contemporaneous, parallel communications across a plurality of frequency channels. Moreover, an automatic frequency control resolves some issues of a free-running clock in an upstream tuner of the central concentrator by performing adjustments based on the average frequency error of a number of active upstream tones. In the preferred embodiments of the present invention, the automatic frequency control (AFC) utilizes a feedback loop for at least each active upstream tone. Also, the average of the active upstream tones is determined and is utilized in providing feedback to adjust the automatic frequency control (AFC).

    摘要： Voltage-induced hum modulation in an amplifier can be caused when shunt capacitors begin to saturate and enter their non-linear region of operation. Bypass coils within the amplifier are magnetically coupled to the shunt capacitors and exacerbate hum modulation by coupling additional energy to the shunt capacitors. By introducing a resistance (R) in series with the shunt capacitors (C), energy that would normally be stored in the shunt capacitors (C) is dissipated. As a result, the shunt capacitors (C) remain in their linear region of operation more often and present a more stable impedance. The resistor (R) is especially beneficial at reducing hum modulation at the resonant frequency of the shunt capacitors (C), when the transfer of energy from the bypass coils (L) is at a maximum.
