Description

Phone Line Simulator (POTS Land Line)

Plug an old land line phone or other device into the RJ11 jack, pick up the phone and hear a dial tone.

Take a second duplicate pcb and phone/device, link them with a spare RJ11 cable between them, and dial from one phone to the other.

Hear call progress tones in the phones.

The phone being called will ring until answered.

When a call is answered, the two phones are connected together by the RJ11 cable running between boards and the phones can work as if they are on a live phone service.

Modems can also call each other.

Useful for testing devices, creating a local intercom, and other nostalgic purposes.
