Network interface device. Not to be confused with Network interface controller. In telecommunications, a network interface device (NID; also known by several other names) is a device that serves as the demarcation point between the carrier's local loop and the customer's premises wiring.
Several types of NIDs provide more than just a terminal for the connection of wiring. Such NIDs are colloquially called smartjacks or Intelligent Network Interface Devices (INIDs) as an indication of their built-in intelligence, as opposed to a simple NID, which is just a wiring device. Smartjacks are typically used for more complicated types of telecommunications service, such as T1 lines.
