Abstract
A switching controller controls two switches, which connect a first communication terminal such as a telephone set and a second communication terminal such as a facsimile machine to the same communication line. Under certain conditions, such as when the second communication terminal originates or answers a call for the first communication terminal, the switching controller monitors the status of the first communication terminal and automatically disconnects the second communication terminal from the communication line responsive to that status. For a telephone set, the monitored status is the on-hook/off-hook status.
