SyncE in Boundary Clock Mode for G8275.2 Telecom Profile
G8275.2 profile is specified for L3 unicast network and is based on partial timing support from the
network. This means that not all network nodes may participate in PTP protocol. In this mode, SyncE
input frequency reference can be used as a frequency-assist for PTP. The physical layer (i.e. frequency)
output is controlled by both, the input (from SyncE) and PTP engine. Unlike in G8275.1, here the
physical layer output is NOT directly from input reference and hence not traceable and cannot be used
for SyncE output distribution. SyncE output is disabled in this case.
The figures below show the flexibility of specifying the ports for operation in this mode.
