I would be interested in hearing a detailed > explanation for that. Its simple: a TA or router allows you to do only that things, the TA or router was designed to let you do. A passive ISDN card allows you to do everything ISDN allows you to do. Sidenote: there is an exception to what i just said. I know of one manu- facturer of ISDN routers who built a thing called "remote CAPI" into their routers, which allows you to access the ISDN by issuing CAPI messages over IP. If you want to know what CAPI is, look at www.capi.org. In case i were in the situation i was, when i started ISDN driver writing under FreeBSD, today, i would just buy such a device and done. > > Hopefully - and the code is already there - i4b will run with the existing > > PPP code, although i don't see the need: bonding two B-channels together > > does not make much sense here. > > Why not?

And the strange thing happening here is, that ISDN (voice) communication is cheaper than analog voice communication since the beginning of this year :-) The conditions under which it pays to use ISDN and/or to use features ISDN is able to provide are just _totally_ different in Europe and the US. hellmuth -- Hellmuth Michaelis Tel +49 40 559747-70 HCS Hanseatischer Computerservice GmbH Fax +49 40 559747-77 Oldesloer Strasse 97-99 Mail hm [at] hcs.de 22457 Hamburg WWW http://www.hcs.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
