Description: PTP Master/Slave [1204-12]

Precision Time Protocol (PTP) is a protocol that can be used to synchronize computers on an Ethernet network. The 10/100 PTP Master/Slave option card supports PTP Version2, as specified in the IEEE 1588-2008 standard (PTP Version 1 is not supported), via one (1) Ethernet port.

The PTP option card implements a PTP Ordinary Clock that can be configured to run as:

• A Master Clock, in which case it transmits PTP packets via the Ethernet port, with information about the current time and synchronization reference selected by SecureSync.
• A Slave Clock, in which case it provides to the SecureSync device a time and synchronization reference retrieved from information carried by the PTP packets received via the Ethernet port.
• A Master/Slave Clock, in which case the PTP option card can change mode according to priority and quality criteria compared with the other PTP Clocks on the network.
