The ‘Phone’ socket can be used to connect a normal telephone in parallel to the telephone line (for example to make
calls). Please note that this socket is NOT always active;
it depends on the status of the ‘Hook’ key of each Hybrid.
When the Hook key is
pressed the Phone socket is not active. The Phone socket has the same pinout as the “line”
socket.
