Tactical Switches


The MTX-MR Secure Voice Switch is a scaled down version of the MTX-R RCS conferencing switch ruggedized for military installations and applications. It provides the reliability and space efficiency that is critical to tactical operations. Its primary function is to connect up to 16 ISDN (BRI) telephone lines to up to 32 crypto devices or encrypted radios. By automating the military’s unique conferencing and tactical communication requirements, the MTX-MR reduces operator errors and permits switching among any telephone line and crypto devices. The switch can handle 32 simultaneous conferences.
