DARK TERRITORY POWER SWITCH SYSTEM
TCS has designed a DTMF tone-controlled power switch system for mainline application. The system uses a vital processor, mainline-style switch machine, radio transceiver with vital message-check circuits, and a digital audio recorder for logging time-stamped radio messages. The system will work with or without wayside switch position indicator signals.
