I'd like to thank all of you that have responded for the information.
I should have mentioned previously that we do have a Netwatch program
running. Our problem is that periodically our Ethernet jams so that
Netwatch-type programs won't run. We haven't been able to figure out
yet exactly what the problem is. Our Ethernet consists of several
segments connected by inline barrel connectors with a total length of
less than 500m. We've found that we can fix the problem by
disconnecting the "backbone" at one of these connectors and
reconnecting it. If a more hardware oriented Ethernet analyzer can
diagnose this sort of problem that's the sort of thing I'd like to
get. I asked about DELNIs because we have several and I wondered what
effect they have when mixed with real transceivers on an Ethernet.
DELNIs aren't mentioned in the 802.3 standard and I haven't been able
to find any definitive DEC documentation.
