You may avoid a possible service charge by completing the following steps before scheduling a repair trip.
Check each phone/device to determine if the problem is with your equipment.
Connect a working phone to your test jack.
If copper: Your test jack will be outside in a grey box labeled Telephone Network Interface. You will need a flat head screwdriver to open this box.
If fiber: Your test jack will be on the back of your ONT (Optical Network Terminal) labeled PHONE 1 or PHONE 2 (if you have a second line). If you still do not have a dial tone after testing with the test jack, please unplug the power from the ONT for 2 minutes by removing the power plug from the back of the ONT (not from the wall outlet), then test again.
