Sangoma pioneers WANPIPE ADSL card to support FreeBSD
By Jeremy C. Reed
In July, Sangoma Technologies announced a new internal broadband ADSL modem for FreeBSD. Then at LinuxWorld, the WAN communication hardware and software manufacturer demonstrated the S518 ADSL for the first time in public. According to Sangoma, this will enable open source server manufacturers to be able to provide added value by integrating broadband ADSL support.
"FreeBSD is the system of choice for ISPs who want to use open source," said Sangoma Technologies sales engineer, James Scott. "It has a reputation of being somewhat faster, more secure and more robust than Linux. Many of our OEM customers providing Internet and security servers use FreeBSD or OpenBSD."
Currently, this PCI 2.2 card is not supported under NetBSD, OpenBSD, BSD/OS, or Darwin OS. Sangoma will support these as the market demands, Scott said. (In addition to FreeBSD, the S518 is supported by Linux and Windows operating systems, and will soon support Sun Solaris.)
The GUI monitoring software and utilities have been ported to Java, Scott said, so they all are available.
Under FreeBSD, the drivers support PPP over Ethernet and ATM, Ethernet over ATM, and IP over ATM.
"Some code, in particular, part of ADSL, does not belong to Sangoma, and therefore we cannot donate it to the community," Scott said. "However, we have written an open source operating system abstraction layer so that this block of object code can still be compiled into any kernel."
According to Sangoma, the S518 connects on a POTS line and provides the highest possible line speeds to any currently installed DSLAM installed in North America. It complies with the ITU G.992.1 (G.DMT), ITU G.992.2 (G.Lite), ITU G.992 Annex A, Annex C, and ANSI T1.413 Issue 2 ADSL standards. And data rates range from 1 Mb/s upstream to 10.5 Mb/s high speed downstream.
For the past few years, Sangoma has provided WAN hardware (such as high-speed serial cards with integrated CSU/DSU for T1/E1 circuits) for FreeBSD and OpenBSD. They also provide WANPIPE software and kernel device drivers which can be installed using the pkg_add command. (The kernel must be configured and rebuilt.)

I can do for solucionated?
For production, the S518 is great because it does not crash, properly recovers in case of line failure (what the routeurs did not), and can work with Linux SFQ (safe fair queing, I don't know how this translates to BSD) which is a must in order to run anything but a toy site with a limited bandwidth (enables to keep latency resonably low).
See http://pliant.cx/ which is running FullPliant
operating system, and is connected through an S518.
