In a fiber-to-the-curb telecommunications system a method of network synchronization is presented in which data is transmitted from a broadband network unit to devices in a residence on a downstream carrier frequency, where the downstream data rate and the downstream carrier frequency are integer multiples of a sub-harmonic of a master clock. In the upstream direction, where data is transmitted from the devices to the broadband network unit, upstream data is transmitted on an upstream carrier frequency and the upstream data rate and upstream carrier frequency are integer multiples of a sub-harmonic of a master clock. Digital downconversion is performed on the data received at the broadband network unit to produce baseband samples.
