Alstoms Reason and DS Agile Ethernet switches combine interoperable redundancy protocols and fibre-optic communications for ultimate reliability of the substation communication networks. They support the flexibility to architect standard Ethernet networks, for refurbishment and greenfield digital applications alike. High capacity Gigabit communication is available, for IEC 62439 fault tolerant networks built as PRP redundant star, or HSR redundant ring.

Substation GPS clocks are the precision time references across a power grid, used to synchronise the devices which protect, and control the stability of the system. Grandmaster clocks are designed for full digital architectures, accurate to within microseconds, capable to distribute the vital IEEE 1588 PTP reference around the substation Ethernet network to subscribing intelligent devices.
