Abstract

PURPOSE:To ensure the simple interboard transfer by installing the MF signal transmitter to the transfer attendant board at a remote place. CONSTITUTION:In case attendant board 11 transfers the call to attendant board 12 in the state under which the incoming call is connected to board 11 of the remote place via exchange 1, board 11 transmits the order signal to position equipment 8. Thus equipment 8 is connected to position equipment 9 via connector 13. Equipment 9 transmits the closure signal to position trunk 5 and also performs the order display for board 12. Thus the order becomes possible between boards 11 and 12. And when the transfer signal is transmitted from board 11, equipement 9 catches MF signal transmitter 10 to transmit the number information on of board 11. Transmitter 10 transmits the number information of board 11 to MF signal receiver 6 via trunk line 15. As a result, the incoming call of incoming trunk 2 is transferred to board 12 via exchange 1 and trunk 5 each.
