Have you considered getting a pair of Lion DataPumps ? See Julian Stacey's home page on freefall. These look just like internal modems, support PPP on-board and channel bonding too. AFAIK, Barry has an office in the US now. Of course, it would be really nice if you waited Teles out so you could test the ISDN stuff in the US :) > The ADTRAN TAs are also nice in that they do channel bonding > transparently.

They can handle 2 B-channels simultaneously w/o any problem. It's hacking it into the kernel. What do we use as the protocol ? MPP ? BACP (unbelievably ugly !) ?

Just enter the incoming/outgoing phone numbers into /etc/isdn and say "telnet the-other-guy" and, hey presto !, the connection gets made for you. Well, you need a route and have to configure the ii? interfaces, but it's no more difficult than setting up SL/IP or PPP. This is IP on top of HDLC, totally transparent. Most of the dirty work gets done in /etc/rc.isdn. --- Gary Jennejohn (work) gjennejohn@frt.dec.com (home) Gary.Jennejohn@munich.netsurf.de (play) gj@freebsd.org
