RSM - Remote Switching Matrix

Remote Switching Matrix

The RSM is a DTMF controlled remote switching matrix for switching from 1 to 256 input lines to a common bus to which may be connected any apparatus or circuit appropriate to the user’s objectives. The RSM consists of a card cage containing one controller and one to sixteen 16-Line Selectors.
