The packets that arrive over your ATM PVC will be (probably) AAL5-framed, possibly with a SNAP header. You're unlikely to use this encapsulation over your HSSI interface (you're probably using cisco hdlc or ppp). So, unless you're planning some funky excursion into cells-in-frames, you're going to have to re-encapsulate -- which means you probably want to route. There is ATM support in FreeBSD, and I presume it handles PVCs if it does anything. Your questions really are, I think: + does anybody sell a DS3 ATM adapter which is supported by FreeBSD? + does anybody sell a HSSI adapter which is supported by FreeBSD? + will FreeBSD support (insert encaps here) over ATM encapsulation? + will FreeBSD support (insert encaps here) over HSSI encapsulation? > Any ideas? suggestions?

Just another good reason to avoid ATM, I suppose :) Joe To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
