I remember this well, initially we were caught out because we were so used
to putting H4005s everywhere, I can't remember how we managed to rustle up a
pair of H4000s overnight :) I also remember getting grief from the local
Digits at RKG (DEC Gateshead was the 'Royal Kingdom of Geordies') because we
were breaking the 4-3-2 rule with a pair of DEREPs, they told us the correct
bridging setup was DEREP - DEREN.
You missed out the DEREN which was the correct
answer to 'what shall
I use as a repeater device on the other end of my DEREP'
The device on the other end of a DEREP-RA would be another DEREP-RA.
The technical manual says that for local use you use a single DEREP-AA,
using an AUI cable from each of the DEREP-AA AUI connections to
H4000 vampire taps on your two thickwire cables to be joined. I _think_ that the DEREN worked the same way (single
for local
use, two for remote use), and I _think_ it was later than the
DEREP.
The installation manual for the DEREN-RA indicates that you could
put a remote bridge on the "other" end instead.
This is probably what we were told to do, I can't remember what year this
was unfortunately.
