  • NID Troubleshooting Step 3 Testing your Connection at the Network Interface Device

    Connect a telephone that is in good working condition to the jack on the Network Interface Device. If your phone works properly when plugged in at the NID, then your problem is somewhere in the inside wiring or jacks. You can use the Verizon Troubleshooter to diagnose your telephone's problem and request a repair if an issue is detected.
