I'm not an expert, but at that speed, wouldn't it be better to use an ISDN-router that you can plug together with your network-interface ? That way, it would use less CPU-time. If you've got a leased line, the cost of an ISDN-router isn't that much in comparison. > Is this true? If so, how > hard. What do you actually have to do?

Better ask these questions on freebsd-isdn. Again, if you've got a leased line, there's no point (IMHO) in using a TA. It is intended for dial-up only, like a modem. cheers, Rainer -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |Rainer Duffner, E-Mail: duffner@fh-konstanz.de | | & Rainer.Duffner@konstanz.netsurf.de | |Fachhochschule Konstanz, Germany | |"What's a Network ?" - Bill Gates, early 1980s | | WWW:http://www-stud.fh-konstanz.de/~duffner | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-newbies" in the body of the message
