Abstract

PURPOSE:To deliver repetitive dial pulse when the opposing party is busy, by providing memories, in the dial unit of a telephone set. CONSTITUTION:When the telephone number is inputted to the push button dial 1, dial pulse is delivered via the dial pulse generator 2, hybrid circuit 4, bridge circuit 5, and hook switch SW, and dial signal is stored in the memory 3. When the opposing party is busy, the content of the memory 3 is read out with a given time distance by the timer 9 by depressing the dial button 10, and the dial pulse is repetitively delivered through the dial pulse generator 2, hybrid circuit 4, bridge circuit 5 and relay switch RY.
