Abstract
A scalable fault tolerant cable headend switching system using modular switching or multiplexing devices. A radio frequency switch connects a series of adjacent cable headend element to a series of output cables. At least one spare cable headend element is connected along with the series. Each cable headend element is configured to be readily swapped with adjacent elements. Output cables are cascaded away from a faulty element toward a spare element when a fault is detected.
