Re: [Business] Buying a DOCSIS 3 Compliant Cable Modem

I was just in the Fry's San Marcos (north San Diego County) store, and they have the SB6120 on the shelf for $120. It is truly amazing that the price is so cheap when DOCSIS 3.0 service is just starting to be rolled out in most places.

I can't speak for Time Warner, but word from Cox HSI is that they can't presently provision this model, meaning that there might be more than a few frustrated customers who purchase one of these and find out that they can't use it.

In order to to encourage sales of this new model, Motorola should have allowed it to be provisioned as a SB5120 (or some other DOCSIS 2.0 model) now, so that it could operate in DOCSIS 2.0 mode until the customer's ISP upgrades to 3.0 service.

I'm sure it can work in 1ch mode but cox might not have a "tested" config yet for it

From what I read in the specs, the SB6120 is backward compatible with DOCSIS 1.0, 1.1, 2.0 and supports IPv4 as well as IPv6.

I think the problem is having a config file ready, ie Motorola provides a generic config file to the cable company, then the cable company decides what settings need to be adjusted for their system, and builds (or pays Motorola in this case to do it) a config file for each tier they plan to offer, tests it, tweaks it if nessesary, retests, etc.
Moto would probably provide a D2 version if requested/payed for, but Cox maynot be willing to release it, or may still be testing.

What I was envisioning would be the SB6120 telling the provisioning system "Hello, I am an SB5120", so that whatever provisioning was used for that model would set up the 6120 for DOCSIS 2.0 service, without the need to develop/test any additional configuration files. Then, in the future, the proper file could be sent out to enable the DOCSIS 3.0 capabilities of the SB6120.

Obviously, I do not know the internal details of the SB6120, but it seems like Motorola could have programmed in a default condition such that this model would accept and respond to the 5120 configuration files that the ISP is already using.

I'm not sure I see the value in that.
Rather then expending time/money/energy on making the 6120 act like a 5120 (sort of like buying a truck with a big V-8 and then cutting 7 of the sparkplug wires)
when with less effort/time/money you could write a generic "I'm a 6120, but I only run in D2 mode"
or what's really needed, "I'm a 6120,running in D3 backward compatible mode, limited to XXX/xxx speeds"
But any given cable provider stiil needs to be sure that mode will work on their system before they go with a system wide release.

I guess there are several options as to what Motorola could have done.
