The TTC-1 provides an interface between a tone remote control and a base station or repeater using the F1-F16 standard EIA function tones over a dedicated phone line, microwave path or telemetry link. The TTC-1 can also provide optional remote control of a base station using a regular phone line (POTS) with DTMF phones from anywhere on Earth. Activation of Monitor and PTT is controlled by VOX or * #. The TTC-1 is flash-upgradeable and includes automatic level control to compensate for line loss caused by remote controllers at greater distances or different manufacturers. It also includes programmable voice confirmation of functions and alarms, voice and Morse ID, and over-the-air voice and tone warnings.
