Abstract
A communication terminal apparatus connected to an analog communication network includes a line interface circuit, a digital signal processing circuit provided with a network control signal processing section and a modulation and demodulation processing section, and a power-saving control device to carry on the operation of the line interface circuit and the network control signal processing section and suspend the operation of the modulation and demodulation processing section so as to be into a power-saving state when a predetermined power-saving state change factor has occurred in a normal operating state, and resume the suspended operation of the modulation and demodulation processing section when an incoming call signal is received during the power-saving state.
