A lot of problematic modems are showing "time not established" errors, despite numerous attempts to re-establish it.

So what I,m curious about, can the T3 actually cause an outage/loss of service if the modem doesn't know what time it is, going off what's written above in bold

Apologies if this is a dumb question
Igni doesn't think I know what I'm saying! He's good, eh?

ToD synchronisation isn't a show stopper AFAIK. The modem substitutes a default time (and its clock ticks are then good). Every 5 minutes it tries again to synchronise time, and so on. All other functions perform, including the 30 second ranging request.

Without inside knowledge, I can't say why the ToD errors occur - but it is a discardable request from the CM and it is possibly due to a large number of CMs simultaneously trying to get ToD after restart or some other event.
