Abstract
Home phone line network devices, conforming to different versions of the standards, are interconnected and interoperable on a UTP transmission medium. Higher order devices support an overlaid dual logical network structure which allows two pairs of higher order devices to communicate simultaneously using two separate frequency bands. A higher order node contains a high speed PHY, a low speed PHY, and either a high and low order MAC or an enhanced MAC capable of supporting dual frequency band transmission, thereby enhancing total system throughput to the sum of the throughputs of each logical network.
