This is a pulse signal to audio signal converter designed for dial-type old telephones. Your old phone can convert the original pulse signal into a dual tone multi-frequency (DTMF) signal through this converter. The number dialed by your telephone can be recognized by the modern switch for dialing purposes. In this way, your love machine is not only used as a display, but old telephones decades ago can be used in daily life.
For cities or regions that do not support the old dial telephone pulse dialing signal, it is especially suitable for users who are connected to the network or fiber.
The enhanced version can be used on standard local line and fiber or network adapter lines as well as on personal switch lines. You can dial the # * number. Easy automatic voice communication. There is a “Redial” feature.
Easy to install and use, no need to change the phone. Simply connect the 2 wires of the telephone to the designated terminal block and plug in the crystal head of the telephone line to use it; please refer to the picture wiring provided above;
When installing, after the line is connected, the indicator light of the converter is on after the phone handle is lifted. (If the indicator is not lit, please adjust the connection between L1 and L2), you can make a call; each dial will be heard in the headset. The same two-tone signal sound as a modern push-button phone.
