REDUNDANT ETHERNET BOARD

V01009

Figure 24: Redundant Ethernet board

This board provides dual redundant Ethernet (supported by two fibre pairs) together with an IRIG-B interface for
timing.
Different board variants are available, depending on the redundancy protocol and the type of IRIG-B signal
(unmodulated or modulated). The available redundancy protocols are:
● SHP (Self healing Protocol)
RSTP (Rapid Spanning Tree Protocol)
●
DHP (Dual Homing Protocol)
●
PRP (Parallel Redundancy Protocol)
●
● HSR (High-availability Seamless Redundancy)
There are several variants for this board as follows:
100 Mbps redundant Ethernet running RSTP, with on-board modulated IRIG-B
●
100 Mbps redundant Ethernet running RSTP, with on-board unmodulated IRIG-B
●
100 Mbps redundant Ethernet running SHP, with on-board modulated IRIG-B
●
● 100 Mbps redundant Ethernet running SHP, with on-board unmodulated IRIG-B
100 Mbps redundant Ethernet running DHP, with on-board modulated IRIG-B
●
100 Mbps redundant Ethernet running DHP, with on-board unmodulated IRIG-B
●
100 Mbps redundant Ethernet running PRP, with on-board modulated IRIG-B
●
100 Mbps redundant Ethernet running PRP, with on-board demodulated IRIG-B
●
● 100 Mbps redundant Ethernet running HSR, with on-board modulated IRIG-B
100 Mbps redundant Ethernet running HSR, with on-board demodulated IRIG-B
●
