The device is an IEEE 1588-2008 (PTP v2) and SyncE compliant 8-port Gigabit switch capable of acting as a Transparent Clock and, with aid of the Synchronous Ethernet protocol, to achieve synchronization in the nanosecond range.
It is equipped with the latest technology and may be operated via a comfortable web interface. It may be used as an industrial Ethernet switch for rough environments requiring carrier grade switching. The job of a Transparent Clock (TC from now) switch is very simple to understand. It just modifies PTP messages as they pass through the device. Timestamps in the messages are corrected for time spent traversing the network equipment.
This approach improves distribution accuracy by compensating for delivery variability across the network (called Packet Delay Variation - PDV). SWITCH-EVO does not alter any other message other than Sync and Delay_Req packets and is completely transparent both to the PTP Master and to the PTP slaves. This approach is particularly needed because the time it takes for a network switch to process a packet greatly varies depending on network load.
