I am not too keen on the idea of having the Cisco DPC3010 dumped on us - this modem has been obsoleted by Cisco. https://www.cisco.com/c/en/us/obsolete/video/cable-modem-model-dpc3010-epc3010.html

I understand this modem was specified because it has the voice gateway and battery system and is free BUT it is still obsolete!!!

If I were to use the Arris SVG2482AC, isn't this the same as the Arris TG2472.  I believe the TG2472 is used by the Cox Contour Panoramic system but I think Arris SVG2482AC is commercial version? The SVG2482AC has a battery backup voice gateway as well
