Tdd ptp or eptp?

dish which I would have tossed off the tower when I was installing it if I had 
an alternative.

  +1 about.


  So I assume we'll see about half the current latency with 2.5 msec? I can 
live with that for most links.

      2.5 msec frame allows for sync and improves PTP latency as compared to 5

      ePTP cannot be synced as communication is driven based on dynamic data 
from each link.

      Yep, I'm pretty sure it doesn't use fixed frames in ePTP mode... trying 
to sync that sounds like it'd end up like airmax sync.

      2.5ms frames make sync a lot more useful for ptp though.

      But that depends on frame timing which would leave you at the current tdd 
ptp (5ms today, 2.5ms after 2.5).  I'd love to see the 2ms latency be synced 
but I don't see how that would be doable.

      No, I mean exactly what I said ePTP sync.

      There's no reason that I'm aware of that the ePTP up\down cycles couldn't 
be synced. The regular sync has to deal with potentially dozens of clients. The 
ePTP just has to deal with one.

      Eptp sync doesn't sound possible.  That's what the tdd ptp is for.  Do 
you mean the 2.5ms timing?

      Is it, thought?  ;-)


      FWIW, I have some ePTP up (eagerly awaiting ePTP sync!) and no issues 
that I'm aware of.

      How long has it been up?  According to Cambium I'm the only one that's 
been experiencing a bug and it's all over the place.  They've got a fix for it 
but it's just so weird that I'm the only one with the problem =/
