Abstract:
1. A system for controlling a duplex communication session between a first transceiver and a second transceiver interconnected via a communication connection, the transceivers capable of communicating in an echo-cancelled mode and in a split-band mode, and the duplex communication session having a data phase that occurs subsequent to a training phase, the system comprising: logic configured to determine an echo-cancelled transmission capacity and a split-band transmission capacity of the first transceiver during the training phase, the logic configured to cause the transceivers to communicate in the split-band mode during the data phase if the split-band transmission capacity is less than a specified transmission capacity for the first transceiver, the logic configured to cause the transceivers to communicate in the echo-cancelled mode if the split-band transmission capacity is greater than the specified transmission capacity, the logic further configured to disable one of the transceivers from transmitting at least one overlapping carrier during the data phase based on a comparison of the echo-cancelled transmission capacity to the specified transmission capacity if the split-band transmission capacity is greater than the specified transmission capacity.
