said by KennesawMtn:But what about U-verse customer self installs like for internet only? I'm having that done, going from traditional DSL (with a external splitter and home run) to U-verse VDSL. In that case does the tech doing the line's swapover at the neighborhood box ever even come to the house and look at the NID? I'd be surprised if they do. In my case, my NID is 1989 vintage and is not compatible with DSL splitter modules that fit inside the NID. My current splitter is a seperate one in its own external housing that I mounted next to the NID in 2005.
At least in my area, techs are dispatched to make the connections @ the crossbox/VRAD, and also go to the house to verify the VDSL2 signal at the house, inspect the drop/NID & update/replace as necessary.
While at the house, techs are supposed to knock on the door, and if the customer is home/available, go inside and verify the VDSL2 signal makes it to the modem jack. If good, then good. If the signal is not stable/good to the modem jack, any inside wiring work is potentially billable to resplice existing wiring or run new wiring. If the customer is not home, the NID is tagged/labeled, any existing inside wiring that was connected before is connected again. If the existing wiring will hold the signal, all is good. If a technician revisit is required for a failed self installation & the signal is good to the NID, the revisit is billable
