APPARATUS FOR CONTROLLING LINK TRANSCEIVER IN PAGING SYSTEM

摘要

PURPOSE: An apparatus for controlling a link transceiver in a paging system is provided to enable a half-duplex communication between the paging system and link transceiver when an interlocking operation between paging systems different from each other is desired without a separate path, by implementing a controller module for controlling an interface between the systems and a radio frequency device. CONSTITUTION: A delay part(310) receives an RTS signal and delays it by a set value. An analog modem(350) receives the delayed RTS signal and data via a transmission device. A power supply part(320) provides a power supply so that a board can be operated normally. A clock generator(305) generates a reference clock related to a delay timing at the delay of the RTS signal. An LED display part(315) shows an operation state of the board of a link transceiver controller module(TRCM)(300). A controller(325) controls a key signal for turning up and down a link transmitter(355). A signal generator(335) generates the key signal. An impedance matching part(340) generates a signal tone corresponding to the key signal. A relay(330) transmits the key signal which is matched at its transformer part.
