<p>Patch recording and recall for audio and video is accomplished by detectors (24) uniquely associated with each jack (12) detect the presence of a plug in the associated jack (12). The connection sensors provides a signal identifying that a connection has been made when a plug is inserted in the jack (12). A controller (26) receiving the connection signal stores each consecutive signal in memory (31). Since each connection signal is uniquely identified with a jack in the panel (10), the stored connection signals are subsequently retrieved by the controller and a patch signal corresponding to the retrieved connection signal indicating a unique jack for the patch to be constructed is provided by the controller (26). Interface with the operator/technician is accomplished through a standard VDU (32) or other appropriate means such as a synthesized voice system (34).</p> |
