About 3,500 of the STB supported by QT/QT+ (the DSR-470) will not be supported on NAS or NAS RAC platforms, so even with a migration to NAS or NAS RAC, operators will need to replace DSR-470 equipment in those customer homes by the end of 2019.
It is important to note that this announcement does not have any impact on the HITS transport services provided by Comcast Technology Solutions.
Comcast and Arris both have programs in place to answer your questions about the process, equipment and related costs of transitioning your QT/QT+ STB to their solutions.
