Abstract: PURPOSE:To accurately measure a line connecting time independent of the operation state of a communication equipment by storing an information regarding a line-releasing time in a memory means at the time of releasing the line. CONSTITUTION:If a telephone set is hooked on at the time of ending a transmission, the line is released at the time of changing a connecting point cml to a telephone TL-side. If the telephone TL is hooked off at the time of ending the transmission, a subcontrol part 6 receives an instruction to wait, and turns a main power source 7 off, thereafter, stores the time of releasing in a releasing time memory, then turns the main power source 7 on, and further, displays a capturing time (caturing time of facsimile+a time which is kept in off-hooked state by a user) and its charge, then returns to a stand-by state. This means that, even if the telephone is in hooked off state at the end of transmission, an accurate line capturing time and its charge can be obtained at the time of hooking on the telephone.
