said by DrDrew:That's default operation for the Cisco DPC3008. It happens that way on every provider, unless the provider went out of their way and configured it differently. Cisco and Scientific Atlanta before them has been doing that for years. This isn't a Charter plot, I've seen the same behavior on Comcast, Adelphia, and TWC for the last 12+ years with Cisco and SA modems. Used to have a PDF file that described it exactly from SA.
This actually appears to be the factory default on the cisco 3008
