Abstract
A method and system transmits telemetry control signals with IF payload data from a common cable between an indoor unit and an outdoor unit. The system modulates a carrier signal with telemetry control signals to represent serial data bytes by switching ON and OFF a carrier tone for ON_OFF keying and bandpass filtering such that when transmitted on a common cable, the signal will not interfere with payload data and DC signals.

A method of transmitting/receiving telemetry control signals with Intermediate Frequency (IF) payload data and DC signals on a common cable between an indoor unit (IDU) and outdoor unit (ODU) comprising the steps of:
- modulating a carrier signal with the telemetry control signals to represent serial data bytes by switching ON and OFF a carrier tone for ON_OFF keying and forming a modulated signal;
- and
- bandpass filtering the modulated signal such that when transmitted on a common cable, the signal will not interfere with payload data and DC signals.
A method of transmitting/receiving telemetry control signals with Intermediate Frequency (IF) payload data and DC signals on a common cable between an indoor unit (IDU) and outdoor unit (ODU) comprising the steps of:
- modulating a carrier signal with the telemetry control signals to represent serial data bytes by switching ON and OFF a carrier tone for ON_OFF keying and forming a modulated signal by combining the output of a universal asynchronous receiver/transmitter (UART) with a clock signal from a clock source at a desired carrier frequency;
- and
- bandpass filtering the modulated signal such that when transmitted on a common cable, the signal will not interfere with payload data and DC signals.
