PURPOSE:To interrupt a new signal without intermitting a series of patterns by generating an interruption frame to a frame counter in a signal transmission circuit for the controller of a car telephone base station or the like. CONSTITUTION:A frame (F1), frame (F2) and a frame (F3) are transmitted circulatingly by an output of a ring counter 2 being a frame counter normally. In transmitting a new signal by a frame C (FC); an interruption signal OR is brought into ''H''. The ringcounter 2 is not reset even if the number of countings goes to 2 and the counter counts until the number of countings goes to 3. A gate 12 is opened by a count 3, and the frame C (FC) is transmitted. |
