When you talk of "redundancy transceivers" - what make are they? How do the
transceivers make a decision to flip over which path they talk over - and
back again? How are the switches the transceivers connect to connected to
the rest of the network? Are they interconnected? Do they have any special
attributes to handle the path changes? Have you made any changes to the
DECnet timers etc. to accommodate the lower layer doing path switching? What
else has changed in the network that may have introduced additional delays
and latency to that path switch-over process?

Chipcom Online used to make such transceivers which work in conjunction with
a special central pair of repeaters (usually star-wired to the transceivers
and inter-linked).

You've read the DECnet Phase IV functional specifications to help determine
exactly what the errors you're seeing relate to?

It's not mine, but I like this definition: Legacy = stuff that works.
