So interesting story here...we have three 450m's in the air and they are getting sync over power from a packetflux gigabit sync injector & timing over timing port via a packetflux sync injector 12.
Old style sync seems to work just fine on the 450m. -Sean On Tue, Nov 15, 2016 at 4:06 PM Bill Prince <[email protected]> wrote: > 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. > > > On Tuesday, November 15, 2016 3:03 PM, Chuck McCown <[email protected]> > wrote: > > > Well, sending a pulse sounds like AM to me.
