Abstract
Abstract A paging station remote control system decoder is described. The paging system decoder is responsive to signals generated in accordance to a signalling scheme comprising a series of tones and timed pauses generated by a paging system encoder. The paging system decoder then causes a paging transmitter station to key in an analog or binary modulation mode or to switch from one mode to another without first dekeying the paging transmitter.
