No Dial-Tone or Noisy Line:

If there is no dial-tone on your phone line, there are several things you may try in order to diagnose the issue:

1. Try a different phone in the same jack.

2. Try a different jack in the house, if there is one.

3. Do a NID test, if possible. The NID is the telephone box that acts as a junction point between the outside service line and the inside wiring. If you live in a house, it is most likely outside on the side of the house. If you live in an apartment unit, it is likely going to be in a shared telco room, so a NID test may not be possible. See below for instructions.

Performing a NID test:

1. Open the customer side of the box with a screwdriver.


                    Typical residential outdoor NID.

2. Find the correct NID module, if there is more than one. Not all modules will be active – look for the one with inside wiring connected to it. If needed, open the tab that covers the test jack. Plug in your phone to the test jack, listen for a dial-tone, and make a test call.

3. If you do not have dial-tone, or the line is still noisy at the correct test jack, please call Quantum's tech support at 410-239-6920, ext. 4, and advise the technician of what you found and set up a dispatch*. If the service is active and noise-free at the test jack, you may have an inside wiring issue.

Technical support hours are: Mon-Fri: 9 AM – 9 PM, Sat: 10 AM – 5 PM, Sun: 12 PM – 5 PM.

*Dispatches are usually the same or next-day depending on current workload and time of day. Dispatches may be delayed due to inclement weather, or if the issue goes away.
