PURPOSE: A multi-connection apparatus in the local paging system is provided to achieve multiple connection between a paging control unit and a plurality of paging transmitters using a communication protocol, such as RS-422, RS-485, etc. CONSTITUTION: A paging control unit(200) generates an RF signal according to a paging signal inputted by a user(100), converts the generated signal into data suitable for an associated communication protocol and outputs it to a paging transmitter(400) through a communication line(300). The communication line(300) carries out multiple connection between the paging control unit(200), capable of transmitting and receiving data according to a communication protocol, such as RS-422, RS-485, etc., and a plurality of paging transmitters(400). The paging transmitters(400) converts the paging signal outputted from the paging control unit(200) into the RF signal and transmits it to an associated terminal(500).
