A NID (Network Interface Device) is a enclosure that acts as a legal point of demarcation at the customer's premise. Basically, it is where Phone Company's phone/data wires end and the customer's home wiring starts. The phone company is completely responsible for all wiring up to the NID and the customer is responsible for any wiring after the NID. NIDs are usually located on the side of house close to other utility entrance points. Note: Not all homes have a NID and some may only have a Station Protector at the entrance point. Some common examples are shown below as well as an open NID showing the customer access side with a single Entrance Bridge Network(EBN) module installed.
Since a NID is where the phone company's network stops and the home owner's network begins, it's a great place to isolate problems. For detailed instructions about testing your modem or circuit please reference the NID Test FAQ.
