Figure 246: Enabling PTP in ECT
The PTP VLAN tag must have the same value in station clock and in the IED. The
default value is set to 0.
The PTP VLAN tag does not need to be the same on all access points in one IED. It
is possible to mix as long as they are the same for all devices on each subnet.

Figure 247: Example system
Figure 247 describes an example system. The REC and REL are both using the 9-2
stream from the SAM600, and gets its synch from the GPS. Moreover, the REL
and REC both acts as a boundary clock to provide synch to the SAM600. The REL
contains a GTM card, which has a PPS output that is used to synchronize merging
units that are not PTP compliant. As a side effect, the GTM contains a GPS
receiver and the REL acts as a backup of the GPS on the station bus.
On all access points, the PTP parameter is "ON".
