REDUNDANT ETHERNET BOARD
Figure 24: Redundant Ethernet board
This board provides dual redundant Ethernet (supported by two fibre pairs) together with an IRIG-B interface
for timing.
We supply different board variants depending on the redundancy protocol and the type of IRIG-B signal
(demodulated or modulated). The available redundancy protocols are:
●
SHP (Self healing Protocol)
●
RSTP (Rapid Spanning Tree Protocol)
●
DHP (Dual Homing Protocol)
●
PRP (Parallel Redundancy Protocol)
The variants for this product are as follows:
●
100 MHz redundant Ethernet running RSTP, with on-board modulated IRIG-B
●
100 MHz redundant Ethernet running RSTP, with on-board demodulated IRIG-B
●
100 MHz redundant Ethernet running SHP, with on-board modulated IRIG-B
●
100 MHz redundant Ethernet running SHP, with on-board demodulated IRIG-B
●
100 MHz redundant Ethernet running DHP, with on-board modulated IRIG-B
●
100 MHz redundant Ethernet running DHP, with on-board demodulated IRIG-B
●
100 MHz redundant Ethernet running PRP, with on-board modulated IRIG-B
●
100 MHz redundant Ethernet running PRP, with on-board demodulated IRIG-B
