Abstract
A method and device for use with a communication system having a single cable line containing externally transmitted data within a fixed frequency band for providing interaction between a transmitting terminal device and a receiving terminal device without disrupting the externally transmitted data. A modulator is provided for shifting a signal generated by the transmitting device to a frequency not receivable by the receiving device. A low pass filter passes the shifted signal to a block converter which converts the signal to a frequency outside of the fixed frequency band but which is receivable by the receiving device. An amplifier is provided for amplifying the converted signal and the externally transmitted data for receipt of the amplified signal by the receiving device.
