Abstract
Techniques are disclosed for using Ethernet Layer 1 as a means for transporting audio, control, and status signals between telephones and an aggregator device in a telephone system. Techniques are also disclosed for using the aggregator to determine whether a telephone supports only Ethernet Layer 1, and for using the aggregator to communicate with the telephone using an appropriate protocol based on the results of the determination.
