Abstract
PURPOSE:To prevent a mistake in dialing by selecting a line corresponding to a dial number inputted from a key telephone set, and reading out an origination code corresponding to this line from a memory, and sending it to the line. CONSTITUTION:When a key operation for dial origination is performed in the key telephone set 3, a central processing unit 7 receives that signal, and recognizes the key operation to be the dial origination, and reads out the origination code corresponding to the objective telephone line of the dial origination from the memory 8. It adds the read out origination code to the head of the dial-inputted number of other party, and sends it to a trunk circuit 2 through a data input output interface 6. On the other hand, the central processing unit 7 controls a sound switch circuit 5, and makes it connect between the key telephone set 3 having key-operated and the telephone line 1. The trunk circuit 2 converts information given a line origination code additionally into a dial signal, and sends it to the telephone line 1.
