<p>A media adapter (110) for data communications over a twisted pair telephone network (150) has been invented. The media adapter has a first interface for receiving a first data signal and transmitting a second data signal. A second interface, which is coupled to the encoder and the decoder, transmits the first reduced band width signal to, and receives the second reduced bandwidth signal from a twisted pair telephone network at frequencies within the data band. The data band is at higher frequencies than a voice band used for voice transmission on the twisted pair network. A collision signal generator generates a collision signal when the the media adapter is transmitting the first reduced bandwidth signal to the twisted pair network. The collision signal is transmitted to the twisted pair network at frequencies within a collision band that is at higher frequencies than the voice band.</p> |
