Should be for COAM and leased. If you are having issues – you can email me 1:1 at this work address. Please include your modem make/model and account # so I can investigate. :-)

Subject: [EXTERNAL] Re: [Bloat] Of interest: Comcast AQM Paper
If we see that AQM appears to be not functioning as expected for upstream connections on DOCSIS3.1, what's the right avenue for getting that resolved? (and does that only apply to the Comcast-owned, vs. customer-owned, modems?)

Awesome to hear that you are turning this on both upstream and downstream. Do you know if the wifi stacks in your home routers also have AQM?
