You have a Network Interface Device (NID) and an Optical Network Terminal (ONT) housing on the outside of your home. In the event of no dial tone inside the location, check for dial tone at the NID (see above instructions for Testing from A Network Interface Device). If you get dial tone at the NID, the problem is inside wiring, or equipment plugged into a phone jack. If you get no dial tone at the NID, open the ONT housing to test further.
Testing at the outdoor ONT
Call Triangle at 1-800-332-1201 to report no dial tone at the ONT or NID 24 hours a day, seven days a week.
In some of the Fiber to the Home Exchanges, we have moved the fiber electronics indoors from the Optical Network Terminal (ONT) housing. While the location may have changed, the functionality of the ONT remains the same.
Testing at the indoor ONT
Call Triangle at 1-800-332-1201 to report no dial tone at the ONT 24 hours a day, seven days a week
