Title: Wire terminal equipment
Inventor: OKA TSUNEAKI
IPC: H04M1/2745
Filed: 1988-03-16
Abstract: PURPOSE:To securely and speedily open a wire line with simple constitution after data communication terminates by switching and resetting a switching means from the side of a wire terminal equipment mainbody to the side of a telephone set part when line open is detected. CONSTITUTION:A line open detection means A outputting a line open detection signal when the side of the wire line is in an open state, and a switching control means B are provided. When the transmission of a dial signal by an on-hook origination function terminates, the line open detection signal is outputted from the line open detection means A and the switching control means B switches and resets the switching means from the side of the wire terminal equipment mainbody to the side of the telephone set part. Thus, the switching means for on-hook origination is automatically switched and reset to the side of the telephone set part when an on-hook originating action terminates, and inconvenience that the wire line is still in a trapped state although it is reset to a standby state after data communication terminates is cancelled, whereby efficiency for using the line can be improved.
