According to one configuration, a repeater device includes a first port, a second port, and amplifier circuitry. The first port receives a first set of multiple signal bands transmitted in a downstream direction on a communication link. The second port receives a second set of multiple signal bands transmitted in an upstream direction on the communication link; the second set of multiple signal bands include a first signal band and a second signal band. The amplifier circuitry amplifies the first set of multiple signal bands and the second set of multiple signal bands. A given signal band in the first set resides in a frequency spectrum between the first signal band and the second signal band of the second set. Communications in the given signal band control at least one set-top box coupled to the communication link in the downstream direction.
