15.2 DISTRIBUTED PTP VS. INDIVIDUAL GRANDMASTERS WITH GNSS

In this example, DXD-8's are installed in several studios. In order to keep them in sync, 2 different options are available:
-
Distributed PTP
-
Individual Grandmasters with GNSS reference
The first illustration shows distributed PTP where all the DXD-8's are PTP slaves to an external Grandmaster; in the second
illustration, the DXD-8's are all Grandmaster for their networks and each is locked to GNSS. This second solution is
particularly useful when distances between studios are long and certainly for remote trucks.
