PURPOSE:To set simply the transmission speed without selecting a setting value in response to the transmission speed by frequency-dividing a control clock signal of a main multiplexer to a prescribed value so as to use the result sequentially for the control of a control clock of a multiplexer of the next stage. CONSTITUTION:Remote controllers 3a, 3b are connected to a control section 2 comprising a computer 1 processing data and a system supervisory panel or the like. The remote controllers 3a, 3b are provided duplicatedly and one of them is used selectively by a switching section 4. Time division transmitters 5a, 5b are connected to the remote controllers 3a, 3b and carrier terminal station devices 6a, 6b via the switching section 4. Carrier terminal station devices 7a, 7b are connected to time division multiplex transmitters 8a, 8b. The transmitters 8a, 8b are connected to a repeater 10 via a switching section 9. The repeater 10 is connected to a switching section 13 switching an auxiliary remote controller 11 and plural remote control slave stations 12a...12n. |
