I guess my terminology in my initial email has proven to be incorrect. I have Sportster ISDN card (an ISA card which apparently is a passive ISDN device) inside a FreeBSD 2.2.8 device. For purposes of testing, I could probably arrange a week or two where I could have another, perhaps even 2 more, of these cards installed into hardware on my premesis. As far as what kind of connection I have, I'm clueless. All I know is that I connect the ISDN card into the wall via a standard category 5 cable with RJ45 connectors. The connection is at my house and is targetted for residential use. It's been asked why I would want to use isdn cards and i4b when ISDN routers or serial devices have proven to work reliably in the US. It's primarly that of out of pocket cost and FreeBSD advocacy here. My employer has bought a large number of Sportster ISDN cards for use in connecting to our corporate network. There is a core group of FreeBSD users who have bought their own ISDN router/serial-ta (or simply used standard modem lines); however, FreeBSD would be much more well received here if it supported this one piece of equipment. It's particularly agravating to have hardware which is only usable by Windows. >The ideal setup would be two machines at an S0 bus, three already supported >cards and the special cabling to run isdntrace in analyzer mode on one >of the machines. I don't know if such cabling could be done for an U ref >point Apparently from followup emails, it looks like I most likely have a U ref point. Does this mean we are hosed, or can we accomplish the necessary debugging with just the U interface?

Archie Cobb apparently has found some of the specs. Additionally, if there are technical standards which can only be found by paying for, please let me know. Buying these references for the betterment of the project would defintly fall under the catch-all phrase, "Let me know if there is something I can do to help" that I sent in my original mail. -- William To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
