PURPOSE:To shorten the dialing time of all telephone networks, by switching the kind of dialing by an optional digit. CONSTITUTION:A control command and data inputted from a dial data input circuit 1 are supplied to a control circuit 2. The control circuit 2 discriminates the control command and data from the input of the input circuit 1 and writes or reads data to or a from a storage circuit 3 and outputs dial data to a pulse generating circuit 4, which generates a pulse corresponding to the dial number, and a 2-frequency tone generating circuit 5, which generates a tone signal of a frequency corresponding to the dial number, to drive these circuits 4 and 5, and-these circuits 4 and 5 perform requested dialing. The pulse generating circuit 4 and the 2-frequency tone generating circuit 5 transmit designated output to a telephone line through a telephone line interface circuit 6. |
