For U-verse Internet 25 o 50 - Which cable they would use?

We were told around 3 months ago that we're eligible to U-verse Internet 25 & 50 plus U-verse TV. My question is: How is going to be installed the service? Are they going to use CAT5, CAT5e or Coax wires? I'm also hesitant because I'm not sure if they will run U-verse Internet & U-verse TV over the same wiring and that can affect my internet speeds.

Beforehand thank you very much!
