Cool. So what about the ePTP vs PTP mode? What's the difference? ePTP is
auto-ranging and PTP is not? Does one give lower or more stable latency?
I have some ePMP PTP links now that are in flexible mode. Latency is
decent, less than 10ms average RTT on most of them. But all of them give
me brief spikes of 40, 100, and even >300ms here and there. If either of
the PTP modes gets rid of that, I would like to know, and I don't care
if a little bit of throughput is lost as a result.

Just a quick note on the enhanced PTP mode of operation -
You will see lower latency in most deployments as compared to the TDD
& Flex mode of operation. However, in high interference coupled with
long distance environments the flexible mode will do better in terms
of tput.
At this time, this is per design but we will be addressing and
incorporating some of the good stuff from our TDD/Flex mode of
operation into the enhanced PTP to bring back the tput in the above
conditions.
Please note that we are also working on a 2.5ms frame to reduce
latency in the PMP mode of operation.
Thanks
