Abstract
A communication apparatus (e.g., a facsimile apparatus) has a monitor circuit to monitor line release after a line has been captured, a memory for storing information on a line release time when the line release is detected, and a control unit for controlling the apparatus. The control unit receives the time information from the memory at an end of a predetermined operation and can compute the appropriate time charge. A stand-by power source powers various components of the apparatus at certain times when full power is not needed, saving power use.
