Abstract

PURPOSE:To simplify transfer from a subordinate station to a master station via line wires, by providing the subordinate station with a means of controlling the holding means of the master station and by resetting a holding state by the answer of the master station. CONSTITUTION:The master station is provided with transmitter-receiver 1 and connected to the subordinate station by radio. The subordinate station, when responding to line wires L1 and L2 to the master station, closes its answer switch to send tone signal f2. The master station places itself in a transmission state by receiving tone signal f2 and relay RY-2 is excited to connect line wires L1 and L2 to the subordinate station. For the transfer from the subordinate station to the master station via the line wires, the transfer switch is closed to transmit tone signals f3 and f4, and with signal f3, calling circuit 31 of the master station is driven to close gate A1. Next, the master station, while stopping the call signal by operating call switch 14, opens gate A3 of holding control circuit 20 to hold line wires L1 and L2. Next, the master station operates transfer switch 26 to reset holding control circuit 20, making connections with the line wires.
