PURPOSE:To allow an MAC control station to easily inpu power-on/off data by composing up control data of a power-on/off data transfer command and an individual subscriber station number and sending it to the MAC station through an up control channel. CONSTITUTION:When a power-on button 11a is pressed, an FF0 is set and an FF1 is set at the same time. A power switch 24 is closed by the setting of the FF1 and +B of a power source 25 is supplied to respective circuits through a terminal P. Consequently, a CPU6 starts a power source data program from a ROM8 to judges the state of the FF, and sets specific bits of the up control data to 10 when the power source is turned on or enters 01 when not and further reads and enters an individual subscriber number from the ROM8 to compose the up control data. The CPU8 starts a transmitter 4 and transmits the composed up control data to the MAC control station through the up control channel. |
