Enhanced Version overview Compatibility across modern and legacy networks The Enhanced Version can be used on standard local telephone lines, fiber optic lines, network adapter lines, and switch lines. It supports dialing numbers and facilitates automated voice communications. A redial function is included for convenience. Pulse to DTMF conversion for old dial phones This pulse signal to audio signal converter is designed specifically for old dialtype telephones. It converts the pulse signals produced by such phones into Dual Tone MultiFrequency (DTMF) tones, enabling the numbers you dial to be recognized by modern switches and dialed successfully. Practical viability on modern systems For cities or areas that no longer support the pulse dialing signal of oldfashioned dial telephones, this device is especially suitable for users of the internet or optical fiber to the home. It allows you to use your favorite vintage phone in today's networks rather than leaving it as a decoration.
