6.5.8.6 PTP Ordinary Slave Clock for Frequency
Traditionally, only clock frequency is required to ensure smooth transmission in a
synchronous network. The PTP ordinary clock with slave capability on the 7210 SAS
provides another option to reference a Stratum-1 traceable clock across a packet
switched network. The recovered clock can be referenced by the internal SSU and
distributed to all slots and ports.
Figure 30 shows a PTP ordinary slave clock network configuration.
