Abstract
An apparatus for use in a cable system comprises a first port for use in coupling to a portion of a cable network for receiving an upstream signal having a frequency spectrum including a first frequency band; and a reflector for reflecting the received upstream signal back downstream via the first port; wherein the first frequency band is different from those frequency bands used by a head-end of the cable network for Internet communications.
Claims22
Apparatus for use in a system, the apparatus comprising:
- a first port for use in coupling to a portion of a network for receiving an upstream signal;
- and
- a reflector for reflecting the received upstream signal back downstream via the first port.
A cable modem comprising:
- a port for use in coupling to a cable system;
- and
- at least one modem coupled to the port for (a) communicating to a two-way network over a first pair of frequency bands and (b) communicating to at least one other endpoint of the system over a frequency band different from the first pair.
A method for use in a device of a system, the method comprising:
- coupling to a portion of a network for receiving an upstream signal;
- and
- reflecting the received upstream signal back downstream via the first port.
A method for use in a cable modem, the method comprising:
- coupling to a cable system;
- communicating to a two-way network over a first pair of frequency bands;
- and
- communicating to at least one other endpoint of the cable system over another frequency band different from the first pair.
