I am looking for clarification on this and there seems to be a lot of confusion about it. After reading about Uverse topology, I believe that it is technically a "dry loop". I'm not talking about the dry loop service (product) offered by ATT; I am referring to the technology itself. Can anyone verify my assumption, or otherwise explain it to me. I am curious, because I am thinking of dropping my Uverse VOIP service, and everyone seems convinced that I need to switch to a dry loop first. That just doesn't make sense to me. If I had a regular DSL line, I could see it, but not with Uverse.
Am I right?

U-verse has three services - TV, internet and voice - You can have any one or all three or any combination. Probably what you really should be concerned about is any promotional prices & how a change in service will affect your bill. Don't worry about how it is delivered.
You can have POTS instead of U-voice. But, again you can have one or both or none.
I guess the technical description of a line without POTS is a dry loop. But, it should not matter to you.

Thanks for the quick response czar.
That's pretty much what I am referring to. A traditional POTS carrying analog voltage versus a pure digital line like Uverse; Essentially fitting the characteristic of a "dry loop". As such, I should be able to port my phone number to another provider without worrying about losing my other Uverse services. Uverse voice (VOIP) is just another digital service on my VDSL circuit.
Would you agree with that/

THe only posts I have seen about porting problems involved BellSouth Ringmaster. THe second telno is "virtual" & needed to be converted to a real number first.
You cannot have another DSL provider because those providers will "own" the physical loop.

Thank you Aviewer!
That's what I thought. I don't need to call ATT to get a dry loop before porting to another provider, because I don't have a traditional DSL line with a POTS splitter. With Uverse, I'm already good to go.

A "dry loop" is a copper pair without 48V DC power on it from the central office (as you'd have with a conventional POTS loop to power the telephone). My U-verse loop appears to be dry. All power for the terminal equipment has to be provided locally by the customer.
Even without POTS a loop could still have 48V DC power. A wet loop with a resistor across the terminal equipment keeps a small "sealing" current flowing that helps keep connections from corroding and opening up, so they tend to be more reliable. The main drawback is the energy cost to the telco.
