My courier I-modem works fine and connects with both channels using standard at commands. However, I am connecting to an ISP not acting like one. I could think of several alternatives that would probably be better suited to multiple ISDN lines including the Ascend products. An Ascend router (Max 1800, pipeline 85, etc) will do all the reconnecting for you if the line fails and give you diagnostic screens as well. With courier (and probably most others) ISDN modems the software will have to do the checking and reconnecting. We use the Ascend ISDN products for a local network with remote sites and they work quite well. >2. Does FreeBSD support ISDN natively or do I have my work cut out for me? AS I said it's done through AT commands. This has been discussed in the questions mailing lists extensively. >3. The Courier's do channel bonding via software... is this going to be a >problem (versus some modems that run dual-b channels via hardware control >eliminating need for software intervention)? Once you send the command string, the modem connects the second channel. If the channel goes down (pick up a phone using a b channel the channel will come back after hang up.
