This automatic telephone line switcher allows TWO separate incoming phone lines to share a single fax, modem, answering machine or other device. When an incoming call is detected the circuit automatically switches that line to the connected device after two rings. This can save you having to have duplicate machines in a small office.
When the line is cleared, the output always returns to its default connection state which is Line #2 so that outgoing calls can be made from that line. Any extensions upstream of the 1167 will operate as normal assuming the line is not already in use.
Suitable for use on PSTN (Public Switched Telephone Network) land lines only. Please refer to user manual below for info on adjusting circuit to suit individual installations.
Kit version includes solder for assembly.Specifications
