Abstract: A remote PHY comprises circuitry operable to communicate with a converged cable access platform and a plurality of cable modems in accordance with Data Over Cable Service Interface Specification (DOCSIS®). The remote PHY comprises buffer circuitry operable to buffer signals to be transmitted to one or more of the plurality of cable modems. The remote PHY may comprise subcarrier insertion circuitry operable to manipulate the contents of the buffer circuitry such that the remote PHY is scheduled to transmit, during a determined time interval, subcarriers having determined characteristics. The subcarriers having determined characteristics may be zero-bit-loaded subcarriers.
