I've already got an ISDN line that I use for my IP connection at home. I'd like to try out * with ISDN, so I'm shopping for a card. I'm in the US, so I need a U interface, not S/T. Can anybody make any suggestions? An awful lot of the cards supported by isdn4linux are hard or impossible to find with a U interface. Can anyone tell me for certain if this card is compatible? http://store.yahoo.com/cuphone/tig12pciismo1.html Thanx, Rob -- Rob Fugina, Systems Guy robf@geekthing.com -- http://www.geekthing.com My firewall filters MS Office attachments.
