Based on what others have said, I think it is all part of the "Precision Timing
Protocol", it is an IP-based way of distributing timing information. Look up
IEEE 1588-2008, or Precision Timing Protocol Version 2.
No more timing pulses.

be a better term to use. From: Daniel White Sent: Tuesday, November 15, 2016

completely new. Instead of interrupting power, they are sending a “pulse” of
power per sync pulse. I don’t recall the details on it at this point. CMM5

Subject: Re: [AFMUG] Packetflux & 450M Timing So.. is "Cambium Sync" still a
power interruption scheme or something completely new? I thought the thing they
were going to move to was 1588v2? On 11/15/2016 1:26 AM, Forrest Christian

I guess I need to be more clear on this. .. There are two types of sync over
power. The first is being called Canopy sync, which is compatible with the
450i and earlier radios. The second is being called Cambium sync and is
compatible with the 450M and I'm guessing later radios. Currently there are
devices that produce the cambium sync pulse... The CMM5 and I'm about 100%
certain that Last Mile Gear has one as well. I have the technical information
I need, just haven't had a chance to get the circuit designed (I only received
it shortly before wispapalooza), let alone tested. On Nov 14, 2016 7:52

No, Cambium elected to drop the traditional sync over power on the 450M. So,
you either need to use timing port sync (via the aux port) or use what they're
calling cambium sync. The 1U injector is very close. I need to finish
validation on the latest board revisions and then will be releasing it to
production assuming there isn't some showstopper I missed. On Nov 14,

Shouldn't the sync over power for the 450M be the same as PMP450i?
How is the 1u sync injector coming?
