You'd also need to support PPPoE, which on most ADSL systems appears as PPP on Ethernet as RFC-1490 bridged encapsulation of the ethernet frames in AAL5 ATM cells. It's unclear that this is worth doing at the ATM level since the CPE devices with an Ethernet are fairly inexpensive; the existing Ethernet interface might be the most cost effective. There's also limited standardization on management interfaces for ADSL CPE equipment. It's been a couple of years since I've been involved with the ADSL forum, but there were proposes to have some management channel to the CPE device (perhaps using ILMI? I don't recall). = Louis Mamakos To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
