Tell me about it..
said by Jmartz0:I would love for ShockTech to explain the process behind sending out software updates. You mention an acronym in the other topic (now locked). What does it mean? I always assumed there was some kind of device at each head-end that the boxes would attach to. Now that everything is digital, does that even necessitate the need for multiple head-ends anymore?
Ok so...there are multiple systems throughout the CV footprint (LI is split, CT, Westchester, NJ North, NJ South etc...there are more within this but you get the idea) Without going into too much detail...CV loads the appropriate UI files onto the DNCS (digital network control system) and carousel that each area reports/connects to.
A whitelist is present which specifies only certain boxes that get the update during this period. This is in case theres an issue and no customers are affected obviously. They then reboot a few head end boxes that are on this system and the boxes now see new files on the DNCS which loads onto the boxes. If all is good they exit a config file in the DNCS to switch over to the new UI data. Run a mass reboot script that reboots all the boxes on that DNCS and they see the new config file and download the new UI.
Hope this is what you were looking for...
