Yes that is what my gut is saying. I spoke with Cisco. They were no
sure? But seems that is the issue.

Seems their use is increasing? Or Dslams that are not Cisco compliant.

On phone with provider now. We will see :)

Sore subject. I have used SDSL lines for like 4 years till recently
getting my own T1. I can't believe Cisco does not make a SDSL router
that works with the SDSL providers in the US. :)

I thought there stuff was standards compliant and would work with
anything?

Now that's a level of desperation I do not want. For that matter they
have a Cisco pix they would use and send back the $3k 1841 with all the
bitchen security software and etc. ;)

Yes and I get motion sick, so I puked a few times already. Seems I might
be making some progress on the telco side of things.

These things are always fun, and always new problems to run into. ;)
