PURPOSE:To realize an economical converting system of incoming number, by transferring the control information of the converted incoming number, etc. to a incoming number converting circuit provided to a signal repeater of a common signal network. CONSTITUTION:A subscriber 5 is usually stored in a switchboard 14 and can be stored also in another substitute switchboard 13 via a switch 70 in case the switchboard 14 has a fault. Thus the subscriber 5 is stored in a substitute subscriber terminal 7 of the switchboard 13 when the switchboard 14 has a trouble. When the switching of the subscriber 5 is over with the switch 70, the incoming number A to be converted and the converted incoming number B are supplied through a keyboard 27. A control center device 26 transmits the control information of the incoming number to be converted fed through a keyboard 27, the converted terminating number, etc. to a signal repeater 23 via a common signal circuit 41. The corresponding information is relayed from the repeater 23 to the signal repeaters 21 and 22 and received by the signal repeaters 21 and 22 to be registered to the incoming number converting circuits 24 and 25. |
