PURPOSE:To improve the processing efficiency of an attachment, by eliminating the need to hold a circuit exchange between the 1st starting and the generation of the 2nd start signal. CONSTITUTION:A terminal 101 connect a clocking device 305 for holding the starting of a main power source 302 to a controller 303 for a specific time even when no signal to the attachment 103 is detected. Then, the main power source is turned on to hold the terminal in readiness for receiving a re-call signal from a network 102. If the re-call signal is detected during this period, the terminal 101 starts terminating operation. On the other hand, when the attachment 103 actuates the terminal 101 once to send a call signal and if there is no answer in this case, it is restarted a specific time later to send the re-call signal. |
