Most residential houses have a test jack located within a NID that allows a customer to isolate their home wiring from the Telco wiring to aid in troubleshooting DSL (or phone) issues. The NID (Network Interface Device) is a legal point of demarcation at the customer's premise where the 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 EBN (Entrance Bridge Network) module installed.





The EBN (there may be more than one EBN depending on how many phone lines your house has) inside the NID will have a test jack where you can directly connect a phone or modem to the TelCo network and eliminate your inside wiring.



For more detailed instructions about checking your modem, phone, or circuit please reference the NID Test FAQ.

Most customers that live in apartments won't have a NID and may have an INI (Indoor Network Interface). Please reference the NID Test FAQ for more details.
