ABSTRACT:
A switcher for selectively routing a plurality of input signals to a plurality of output signal ports. The switcher includes a motherboard disposed in a housing, and a switch card for routing ones of the input signals to an output card, wherein the output card functions to amplify signals received from the switch card. The output card and the switch card are also disposed in the housing, and are electronically coupled to each other and to the motherboard by a signal bus on the motherboard. A controller card is provided for controlling the routing of the input signals to the output signal ports. The controller card, the output card, and the switch card are electronically coupled to each other and to the motherboard by a control bus on the motherboard. A first input frame adapter card is provided for receiving the input signals and providing the input signals to the switch card and the motherboard, and a first output frame adapter card having the output signal ports is provided for receiving amplified signals from the output card and outputting the amplified signals from the switcher. The input frame adapter card and the output frame adapter card are detachably coupled to the housing and to the signal bus on the motherboard.
