Temperature, and the signal of telecommunication corresponding for temperature is exported to gateway by serial clock pin and serial-data pin
In governor circuit 1100.Meanwhile, in this temperature sensing circuit 1200, pre-set above-mentioned Second Threshold, if
When the temperature of current home gateway apparatus 1000 is less than this Second Threshold, the output of warning output pin
T_ALERT signal is high level, at this moment without controlling controlled switch unit 1310 power-off；If home gateway
