What Is a Telephone Plug?
Telephone plugs are connectors for linking communication devices.
Used in telephones and modems, they facilitate signal transmission and power supply. Common standards include RJ11 and RJ12, with RJ11 featuring six pins for standard telephone lines and RJ12 also with six pins, but for some digital devices.
Connection to a communication line allows for voice and data transmission. Additionally, some plugs provide power to devices.
