PURPOSE:To make quickly the translation of dial number and to lighten the burden on software by stopping a regular counter by a coincidence signal outputted from a comparator circuit, and outputting the counted value at that time as a translation code. CONSTITUTION:When a dial translation request unit 101 receives a destination dial signal, and stores the destination number in a register 203, and sets an FF 106, an AND gate 113 is opened and clock signals 107 are inputted successively in a counter 105. If, for instance, the destination dial number stored in the register 103 is C, a comparator circuit 108 compares the content of the register 103 and a memory read signal 109 and detects coincidence, and outputs a coincidence detection signal 111. Thus, the FF106 is reset and the counter 105 is stopped and the notice is given to a dial translation accepting unit 112 by interruption. At this time, the counter output 110 is translation code of the subscriber number C, and the unit 112 is informed of the translation code by this, and transfers it to a succeeding device. |
