J:COM starting to install Motorola DOCSIS 3.0 Modems in Homes


J:COM in Japan has completed trials and is starting to install Motorola’s channel-bonding modems in subscriber homes TODAY. The latest status reports from the lab have found no issues with the SB6120 modems, and J:COM is apparently eager to fulfill subscriber orders coming in. Word is that thousands of users have already signed up for the DOCSIS 3.0 service.
The SB6120 modems are the same ones awaiting certification from CableLabs, but interestingly, they are meeting far more difficult requirements in J:COM’s deployment than they’re likely to see in the Cert Wave process. Cable operators almost always need enhancements to CableLabs-certified devices to make them work with their unique networks.
