Testing From a Network Interface Device (NID)

  • Remove the modular plug from the test jack.
  • Plug in a working single line corded phone.
  • Lift the receiver. If you have dial tone at the NID, the trouble is with either a phone set, accessory, jack or inside wiring. Inside wiring can be repaired by Triangle Communications or by another company, as long as the work meets safety requirements.
  • If there is no dial tone at the NID, the trouble may be outside of the home. Call Triangle at 1-800-332-1201 to report no dial tone at the NID 24 hours a day, seven days a week.
  • Make sure to place the modular plug back in the test jack.

We're here to help. 24/7.
