I have had ADSL service throug Verizon for years. A little over a year ago, I lost both my ADSL and telephone service. I went out to the NIT and plugged a telephone into the jack to see if I had a dial tone. No dial tone so I called for service. The technician said my NIT, over 20 years old, needed to be replaced. He replaced it and put an ADSL splitter in the NIT. (yea, no more dongles throught the hose.)
Yesterday, we lost power and telephone at the same time so I took another trip to the NIT but could find no way to un-plug my side from Verizon's side like I did on the old NIT. After Dominion Virginia Power got the power back on I had telephone and ADSL service again. Verizon must have lost power to one of its repeaters or whatever somewhere along the line.
The question remains, however, how may I determine whether a service problem is on my side of the NIT or yours with no way that I can find to test it.
Thank you.
