So, it seems there are now *two* telecom profiles.
1. G.8265.1 Precision time protocol telecom profile for
frequency synchronization
2. G.8275.1 Precision time protocol telecom profile for
phase/time synchronization with full timing
support from the network
In #1 unicast is required and multicast is forbidden.
In #2 multicast is required and unicast is forbidden.
(Brilliant)
I skimmed through #2, and I think ptp4l will support most of what that
profile requires. They do have an alternate BMC with minor
differences. If those differences are really important to you, then
you will have to patch ptp4l.
Thanks,
Richard
