Circuit operates push-to-talk of mobile station automatically when any button on Touch-Tone pad is pushed for dialing telephone number after making auto patch, eliminating need for engaging microphone before dialing. Circuit remains active for about 2 s after Touch-Tone button is released.-Circuits, 73 Magazine, May 1977. p 19.
