Does anyone know where you get get a modern ISDN modem with at least 4 channels? I am 2 miles from Cable and .5 miles from dsl. ISDN is the only option cause I play games online. Would 256K or 128K Up and Down be enough for playing FPS games on xbox live? I cant find any ISDN modems that are new. Only used ones on ebay that I dont know would work on windows 7. Thanks in advance.
