New 2Gbps service ONLY with Cox modem/router?

In my thread I linked there is a post by _Luke who is a Cox employee. Pretty sure he is a DOCSIS engineer so I think he knows what he is talking about. If I had to guess the ICOMS(customer service database) service code is blocked unless you have the right equipment on your account. If so, a rep. wouldn't be able to override it IMO. Maybe that would change soon as other equipment is tested and approved.

"It’s out there. But need a PW8 for now (and 2 OFDMs plus 1 MS OFDMA)"

The supported modem's list for retail devices does look to be out of date.  Modems like the Netgear CM2000 should be perfectly fine with multi-gig services.  Pretty sure most of the other modems that feature 2.5G+ Ethernet would be fine.

Technically any D3.1 modem or gateway should be able to handle 2Gbps but the problem is a procedure limitation as I mentioned. Pretty sure all D3.1 modems have either a 2.5G port or LAG. Granted, the ones with 2.5G are easier to implement. 

Do you have personal experience overriding someone's account to add 2G service on a non Panoramic gateway/modem? Or are you speculating like me?

I can't speak specifically to the 2G service tier as no such creature exists in my area.  My experience was the result of being offered Gig at a promotional discount.  I don't really need gigabit but the promotional rate was better than my Preferred so I took the bait.  The online ordering process will ask you to choose your preferred option for modem/router.  The options include Pano..... and nothing else.  So I decided to call and see what could be done and somebody was able to process the order using the existing retail device I had.

My existing router has 9 interfaces running currently, I doubt any canned solution designed for the lowest common denominator customer is going to be able to provide comparable functionality.

I think the reason you had to call was a problem with the online ordering system not having a option for retail programed into it. The rep was able to over ride it and manually provision the modem onto the account. I think the issue with 2G service is a restriction built into the database software used to set up that Cox account. It's kind of like how you can't provision a DVR box onto a account unless it has the DVR service. I think it's called a prerequisite. There might be a work around but it doubt it's anything Tier 1 can handle.
