Remote Baseband Switching For Video Microwave Systems (1975)
By Mike Mckeown, United Cable Television Corporation
The capability to remotely insert both full field and inservice VITS video test signals at a microwave headend is a highly valuable maintenance tool to the microwave system and CATV operator. A video routing system also allows video program material to be switched to alternate microwave channels on the occasion of a microwave failure downstream from the switcher or during routine maintenance.
Design concepts of such a remotely controlled switching system, including "touchtone" remote control via wire or radio, are described here. Status monitoring and other refinements are included for the operator who desires a more versatile, more sophisticated switching system.
