Abstract

PURPOSE:To enable representative of extension connection, by storing the designation address of the extension representative group and the extension number in response to the state of station to the first and second memory circuits. CONSTITUTION:After the binary decimal number dial signal from the outgoing register is received and stored in the dial number information storage circuit 1, the address designation to the first memory circuit 3 is made via the decimal to hexadecimal conversion circuit 2 and AND gate group 10, and delivered to the number group via the gate groups 13 and 14. The memory content in correspondence to the address is read out from the first memory circuit 3 and connection control to the extension of the pilot number is made. When the extension is busy at this connection control, the strobe pulse is produced to invert the output of the extension representative connection start FF5 via the gate 11, and the readout output of the second memory circuit 7, i.e., the second extension number of the extension representative group is delivered to NG via the gate groups 13 and 14.
