Linux WAN interfaces (2.6.25):
  • LanMedia family: most/all SSI/V.35, T1/E1, HSSI, T3 boards.
  • Generic HDLC: raw HDLC, Cisco HDLC, Frame Relay, sync-PPP, X.25.
  • Frame Relay: full protocol support.
  • Granch SBNI12 Leased-Line adapters: ISA SBNI12-xx cards.
  • ISDN support: pretty much anything works.
Those are the ones that are "in tree" in the released 2.6.25 kernel. But there are more "vendor drivers" available for stuff not "in tree".

Lots of the Big Boys of telephony are now basing most/all products on Linux platforms, so drivers should continue to become available in the future.

Cheers
