Re: superhub2 - did customer service rip me off?
 

TOD synch between modem and CMTS is necessary AFAIK - read it in the DOCSIS specs.

Re: superhub2 - did customer service rip me off?
 

Not sure if we're debating whether time is required for those services in general or for the superhub.

I do know that the superhub must establish TOD for the network authorisation to complete properly, this is something at the DOCSIS/Network level rather than at the service level. I don't know how much leeway you have with this as I don't know much about the DOCSIS authentication, just that TOD is necessary for it. I imagine it must use something similar to SSL/TLS in that there are signed certificates at work, which will be timestamped and will break if the date is off by a significant amount.

That all being said, this is probably why a TOD failure is a critical event. It might not knock the hub offline or anything right away, but it could cause major issues later if the time goes too far out of sync.

Thanks - re reason TOD is important, have had problems in past with connecting laptops to a domain network which wasn't properly time synched. Time is important to Kerberos protocol.

But doubt superhub2 any different from 1 in this respect.

Re: superhub2 - did customer service rip me off?
 

No difference - both models correctly follow the DOCSIS requirements otherwise they wouldn't be able to register when powered on. The Synch is part of the initialisation.

Indeed, this is what I was saying earlier - time is important for a lot of things.
