Abstract
Exemplary embodiments are related to a dual-mode controller. A device may include a controller configured to convey a signal to a low-noise block (LNB) via a transmission line and circuitry configured to sense at least one parameter of the transmission line. The device may further include logic coupled to the circuitry and configured to determine whether the transmission line is available for transmission based on the at least one sensed parameter.
