4.2. Functional description
The SEM2000C01 operates as a three-port Ethernet switch without management
capability. No adjustments are necessary to use synchronous Ethernet functionality. The
SEM2000C01 periodically sends a Synchronization Status Message (SSM) to all the
devices connected to it as per the ITU-T G.8264 standard. The SEM2000C01
automatically chooses which clock to use as a reference, giving priority to the 10MHz
signal coming from a GNSS receiver module installed in the same mounting frame, such
as the GPS2001C01. If this signal is not available, an internal oscillator is used with a
frequency stability of ±1ppm.
