Cisco 877W with Cincinnati Bell

VPI/VCI is fine. Encapsulation should be RFC1483 Bridged. Multiplexing should be LLC/SNAP or similar.

If all else fails I'd make sure the line is DMT and not CAP (there's still people on CAP with the old Cisco 675's.. I was one of them until recently when they switched me over to DMT). The 877 is DMT only. Have you had DSL at this remote office for a while? Did you just switch to the 877?

We got the 877W as part of an overall equipment upgrade, so it hasn't been in production yet.

I think I got most of the settings you mentioned there right but I haven't checked DMT vs CAP, I'll give that a whirl!

This thing has got me kicked and it's driving me nuts.

I have configured it and it seems to connect but I can't ping anything outside including the gateway given to us with our static IP or the Cincy bell DNS servers.

DSL: Training log buffer capability is not enabled

So the modem seems to be connecting at the correct speed.

Here is my running config

Any help is appreciated!
