Abstract: A signal distribution cable network system in which frequency division multiplexing is employed to provide a plurality of information channels. A channel allocation controller (CT) allocates free channels on request for the transport of signals from a local signal source (SS1, SS2, SS3) to a signal destination receiver (SR1, SR2, SR3) connected to the network. The local signal source includes a programmable modulator (CFS, VCO, MOD) which is set by the channel controller (CT) to operate at the carrier frequency of the selected channel. The signal level of the signals transmitted by the local signal source is measured in the controller and adjusted to compensate for signal attenuation by a command signal sent by the controlle to the programmable modulator in the local signal source.
