Hi Folks, I'm using ISDN-Connections extensively because ADSL is not available. So far it works fine "out of the box" (CentOS 5 PAE). Two questions: 1. for which the fcpci-kernel-modules from atrpm-Repo are useful? 2. Whats about channel bundling? Does CentOS bundling automaticly on every established connection (if it is selected in Network-Configuration) or is it only set/unset with the isdnctrl addlink/removelink ippp0 command? Thats very important because there is no flat-rate on this ISDN-Connection. I intend the use of channel bundling only for remote-access The "simple" user on the connected window-workstations shall not use channel-bundling for surfing. (ISDN is on the server with samba / squid). It's difficult for me to test it because I have only remote-access to this server (start/restart of the ISDN-Connection) Thanks for any hints Timothy
