Abstract
PURPOSE:To automate the establishment of a communication channel to an optional terminal equipment by reading a frequency data of a carrier from a control data to set a channel. CONSTITUTION:When a data processing unit 19 outputs a control data to set a channel to an interface 1, the command is decoded by a decoder 7 and a timing signal is outputted from a terminal (n) to a register 5 and timers 8, 9. A register 6 latches a data from a register 5, a frequency data is supplied to a PLL circuit 13 and an offset command data is supplied to a reception circuit 14. The reception circuit 14 receives the carrier offset by a prescribed frequency only for the demodulation based on an offset command data from the carrier outputted from the PLL circuit 13.
