Abstract
A method of distributed loop control is described. The method includes receiving at a service unit downstream control and telephony information modulated on orthogonal carriers in a first frequency bandwidth over a distribution network. The method further includes transmitting from the service unit upstream telephony information and control data modulated on orthogonal carriers in a second frequency bandwidth over the distribution network. In addition, the method includes adjusting at least one local transmission characteristic when an adjustment command from a head end terminal is received in the downstream control data. The downstream control data is based on prior upstream transmissions from the service unit.
