PURPOSE: A high-speed paging transmitter controller for a single channel is provided to simplify the structure of the paging transmitter controller, and to integrate every function in one device. CONSTITUTION: A leased line interface unit(210) is interfaced with a paging terminal through a leased line. A CPU(250) converts paging data received from the paging terminal through the leased line interface unit(210), according to a predetermined paging protocol. A GPS(Global Positioning System) receiver interface unit(230) receives absolute time information and a reference clock from a GPS receiver, for outputting. A transmitter interface unit(220) is synchronized with the absolute time information and the reference clock from the GPS receiver interface unit(230), to transmit the converted paging data from the CPU(250) to a paging transmitter. And a software storage unit(240) stores programs for the operation of the CPU(250).
