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.

22.13.2.3 Process bus IEC/UCA 61850-9-2LE synchronization
When process bus communication (IEC/UCA 61850-9-2LE protocol) is used, it is essential that the
merging units are synchronized with the hardware time of the IED (see Technical manual, section
Design of the time system (clock synchronization ) ). To achieve this, PTP, PPS or IRIG-B can be
used depending of the facilities of the merging unit.
If the merging unit supports PTP, use PTP. If PTP is used in the IED and the merging unit is not PTP
capable, then synchronize the merging unit from the IED via a PPS out from the GTM. If PTP is used
in the IED and the merging unit cannot be synchronized from the IED, then use GPS-based clocks
to provide PTP synch as well as sync to the merging unit.
