Infineon is one of the companies making transceiver chips for SHDSL, and apparently it's more popular in Europe. Their SHDSL chip family is called SOCRATES, which stands for SHDSL One Chip Rate-Adaptive Transceiver with Embedded Startup. I have considered these chips as a possible alternative SHDSL solution to the morally reprehensible Mindspeed, but unfortunately Infineon doesn't seem any better in terms of openness. The SOCRATES pages on Infineon's website contain nothing but marketing crap, and one datasheet found on the net has confirmed my suspicions: the booty is marked Confidential, Distribution with NDA only.

The only Infineon S(H)DSL datasheet we have is for their 4-channel SDFE-4 (PEF 24624), and its usefulness is quite limited:

• The 4-channel chip is fine for DSLAMs, but for a hacking platform or CPE we want just one channel. We don't have datasheets for any of Infineon's single-channel chips.
• Reading the datasheet has confirmed my suspicions: the datasheet is not sufficient, one also needs the firmware image and the programming manual, which are missing.

For what it's worth, we have put Infineon's marketing briefs and the lone SDFE-4 datasheet on our FTP site.
