Claim Text:
1. A system comprising: a first port, the first port receiving a first set of multiple signal bands transmitted in a downstream direction on a communication link; a second port, the second port receiving a second set of multiple signal bands transmitted in an upstream direction on the communication link, the second set of multiple signal bands including a first signal band and a second signal band; and amplifier circuitry to amplify the first set of multiple signal bands and the second set of multiple signal bands, a given signal band in the first set residing in a frequency spectrum between the first signal band and the second signal band of the second set, the given signal band controlling at least one device coupled to the communication link in the downstream direction; the amplifier circuitry including a first portion and a second portion, the first portion of the amplifier circuitry amplifying the first set of multiple signal bands and outputting the amplified first set of multiple signal bands through the second port in the downstream direction on the communication link, the second portion of the amplifier circuitry amplifying the second set of multiple signal bands and outputting the amplified second set of multiple signal bands through the first port in the upstream direction on the communication link; wherein the first portion of the amplifier circuitry resides in a first communication path between the first port and the second port, the first portion of the amplifier circuitry amplifying the given signal band and outputting the amplified given signal band out the second port; wherein the second portion of the amplifier circuitry resides in a second communication path between the second port and the first port, the second portion of the amplifier circuitry amplifying the second set of signal bands and outputting the amplified second set of signal bands out the second port; and the system further comprising: a first block filter and a second block filter, the first block filter disposed in the first communication path to block a first frequency range of signals in which the first signal band of the second set resides, the second block filter disposed in the second communication path to block a second frequency range of signals in which the given signal band resides; the system further comprising:
