<P>PROBLEM TO BE SOLVED: To provide a communication terminal device capable of reducing power consumption. <P>SOLUTION: The communication terminal device includes a light IF (InterFace) 34, a PON-LSI 32, a PHY 30, a timer 18, a power supply control section 20, power supply switches 24, 26 and 28, and a power supply 22. The timer outputs, to the power supply control section, an operation time information signal 19 giving an instruction of a power supply time zone and a power non-supply time zone for the light IF, the PON-LSI and the PHY. The power supply control section sends the operation time information signal to the PON-LSI, and makes the power supply switches achieve a normal communication mode in the power supply time zone and achieve a sleep mode in the power non-supply time zone, according to the operation time information signal. <P>COPYRIGHT: (C)2011,JPO&INPIT |
