My home box never disconnect although I have no real IP connection (like > telnet, ftp, http and so on). The tcpdump have the following entries: > > 11:57:30.891509 ID-066 LCP: Echo-Request, Magic-Number=273789161 > 0942 000c 1051 b0e9 ff01 1b4d I had the same exact problem. i4b measuers "idleness" using an interrupt on the ISDN card. The LCP Requests come from your provider, and so i4b thinks the line is never idle, because the card isn't. This is of course very bad, because then the whole concept of being idle gets thrown out the window. I wrote a kernel patch for this, and should be in the contrib/ directory of your i4b distribution, but I wrote it for 0.70 and don't know if it works for any later versions. My patch basicaly adds an idle timer to sppp(4) just like ppp(4) has had all these years. This is a bug, that needs to be fixed. Good luck with patching, and let me know if need help along the way.
