Traditionally, only clock frequency is required to ensure smooth transmission in a synchronous network. The PTP ordinary clock with timeReceiver capability on the router 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: timeReceiver clock shows a PTP ordinary timeReceiver clock network configuration.
The PTP timeReceiver capability is implemented on the CPM, version 3 or later. The IEEE 1588v2 messages can ingress and egress the router on any line interface. Figure: Ordinary timeReceiver clock operation shows the operation of an ordinary PTP clock in timeReceiver mode.
