摘要： In order to reduce the consumption of power of an isolator interface and an ADC, it is proposed to operate a calling signal reception or Caller ID signal reception function only with power supplied from the system switch while maintaining the on-hook condition of a telephone. At the time of normal operation, the output of the analogue digital converter is input to an isolator through the isolator interface, and at the time of the calling signal reception or the caller identification information reception, the output of the analogue digital converter is input directly to the isolator.

摘要： The hardware of an over-sampling A/D and D/A converter is provided, which hardware is capable of being operated with either kind of software: one corresponding to a first method in which the over-sampling ratio is fixed and the other corresponding to a second method in which the over-sampling ratio is variable. The value N3 written on the pseudo-frequency-dividing-ratio-register 11 and the value N4 written on the pseudo-over-sampling-ratio-register 21 are converted through a user interface into the frequency dividing ratio N1 by the conversion circuit 12 and the converted result is written in the frequency-dividing-ratio-register 10.
