Open the CIPO recordAbstract From the Canadian patent
In customer access networks wherein information is exchanged according to a transmission method xDSL, a problem arises in that the maximum available transmission capacity is highly dependent on physical conditions of compatibility. If these conditions are modified the modems must adapt , themselves again. If the initial transmission capacity is not reached any longer, the xDSL line is taken out of service. The present invention solves this problem by establishing a communication channel between the modem and a central control logic.
