Carpet is legal as they play tournaments on Challenger level and that classifies. So they have the option of carpet if they want.
In the regulations 38 Surface and Conditions in Note 4 of the Davis Cup rules makes it clear. If carpet is to be laid they have to tell the opposition and ITF, what base it will be laid upon so it fits into the speed regulation.
Check the rules pages 24-25
. The requirement of the surface being used on pro tour is for World Group and Zonal Group I. And minimum of $350,000 of prize money for the pro tour event means it's an ATP World Tour event. So I'd say carpet is allowed only on lower levels of DC.
Anyway, I checked the surfaces of ATP indoor events:
Hard, Acrylic on Wood: Paris, Montpellier
Hard, Greenset on Boards: Basel, Kuala Lumpur
Hard, Greenset: Valencia, Metz
Hard, Decoturf: Rotterdam
Hard, Play-It: Bangkok, Stockholm, St. Petersburg
Hard, Gerflor: Marseille
Hard, Premier Court: San Jose
Hard, Plexipave: Memphis
Hard, Opticourt: Vienna
Hard, RuKort: Moscow
WTF is the only indoor event the surface of which I didn't found. On the other hand, I don't know if World Group must be played on a certain type of hard court, or if being a hard court is enough, maybe there are carpet-like courts that are officially hard courts.
