POWER MONITERING SYSTEN FOR TELEPHONG TERMINAL

摘要

The device comprises a signal detect section (10) for detecting a power control signal, a power operating section (20) for controlling a terminal power according to the output of the signal detect section (10). The signal detect section (10) comprises a ring signal detector (11) for detecting a ring signal from a telephone line to output a control signal to turn on a terminal power, and an end signal detector (12) for checking operation state of the terminal with software to output a signal to turn off power automatically if it was not used for some time.
