Main highlights

This module converts pulse signals into multi-frequency two-tone signals, allowing the operation of old dial phones on modern telephone lines. It integrates practical features such as redial and dial function that improve usability. It fixes the incompatibility between traditional pulse dialing systems and modern telephone networks and restores the everyday functionality of old devices.
The module works with 32V or 48V DC current and a current of 20-40mA, ensuring stable performance. It is made of durable ABS plastic and a PCB board for durability. The standard design fits most dial phones, making it a versatile solution for various vintage phone models without the need for modifications.
The module retains the traditional dialing functions while offering modern dialing options. This balance allows the user to maintain familiar features while enjoying the convenience of modern phone features.
It is designed to revive collectibles and vintage dial phones for everyday use and is particularly suitable for areas where telephone lines no longer support pulse dial system. By bridging the technology gap, users can keep and use their classic dial phones instead of replacing them with modern alternatives.
Installation requires no complicated steps: simply connect the two cables of your dial phone to the designated connectors of the module. It is also compatible with standard telephone jacks, allowing for quick setup without any specialist knowledge or additional tools. Thanks to this straightforward process, users can use the module shortly after unpacking.
