Crosspoint analog data selector

A crosspoint analog data selector for coupling data received on a predetermined number of input channel lines onto a predetermined lesser number of output channel lines in response to commands received from a command source, the crosspoint analog data selector comprising:

• a selector section comprising two or more crosspoint switch sections, each crosspoint switch section including a predetermined number of input terminals and a predetermined number of output terminals, each output terminal being individually energizable, each input terminal being connected to a different input channel line, such that none of the input channel lines are connected to input terminals of multiple crosspoint switch sections, each output terminal being connected to one of the output channel lines such that each output channel line is connected to an output terminal of one said crosspoint switch section;
• and
• a control section responsive to said commands received from said command source to enable the selector section to couple data from a selected input channel line to a selected output channel line, wherein the control section effects a connection from said selected input channel line to said selected output channel line (i) initially enabling the crosspoint switch sections to de-energize their output terminals connected to the selected output channel line, (ii) enabling the crosspoint switch section connected to the selected input channel line to connect its input terminal connected thereto to its output terminal connected to the selected output channel line, and (iii) enabling the crosspoint switch section connected to the selected input channel line to energize its output terminal connected to the selected output line.
