I found a 100 ohm STP shielded cable is ok for isdn?

If I use a normal UTP unshielded cable how can I shield it for about
3 meters because is 5cm near the eletric line?

The distance between TA is a critical factor?
Because in my home some socket are very near ( few cm) and some are very far
(few meters).
Is a problem?

Sorry for my bad english and thanks to all.

Should not be a problem.

'Very far' in terms of ISDN is hundreds of meters.
