Claim:
1. A method, comprising: transmitting data signals at a first frequency band over a first wire in a data cable in a data network; scanning the data network for noise to identify an appropriate spectrum to which to upband the POTS voice signals; upbanding plain old telephone service (“POTS”) voice signals at a second frequency band over a specified frequency threshold, based on the identified appropriate spectrum, wherein identifying an appropriate spectrum comprises monitoring frequencies above the specified frequency threshold to identify a center frequency at which a minimal amount of signal is detected, and wherein upbanding the POTS voice signals comprises upbanding the POTS voice signals such that the second frequency band is centered on the center frequency; and transmitting the upbanded POTS voice signals at the second frequency band, which is different from the first frequency band, over the first wire in the data cable in the data network, concurrent with transmission of the data signals over the first wire.
