Abstract
A dual channel transceiver which operates at two different frequencies and which may be used in a network using older transceivers operating at a single frequency is disclosed. A pilot tone is transmitted by the transceiver when it is using the second channel to cause the older transfers to remain synchronized and thereby prevent them from transmitting data which would otherwise interfere with the data on the second channel. The relative magnitude of the signals on both channels is compared to prevent the detection of cross-talk on the second channel as data.
