Do you have a terminator on the thin-wire cable? The behavior you
describe sounds like DESPR is periodically shutting down the thinwire
segment due to collisions or jams.
Note that the DESPR should be connected directly to the main ethernet
thru an H4005 or equivalent transceiver with a heartbeat disable option.
