Figure 347: Example system
Figure 347 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.
