Chris (and anyone else puzzled by the acronyms),
Nearly all of DEC's ethernet products begin with the letters "DE" for
Digital Ethernet. The remaining three letters of each acronym describe
the product. I don't know all of the acronyms, but here are a few
(including the DEMPR and DELNI).
DEUNA Unibus Network Adapter -- connects a machine to Ethernet
via the Unibus.
DELUA LAN? Unibus Adapter -- IEEE 802.3 version of DEUNA.
DEQNA Qbus Network Adapter
DECNA C???? Network Adapter (used with the PRO series)
DEBNT BI Network T???? (used with BI machines)
DEREP REPeater -- repeats Ethernet signals from one coaxial
segment onto another.
DEBET Bridge E???? T???? -- forwards Ethernet packets from one
LAN to another forming an "Extended" LAN (uses a store-and-
forward technique, whereas a DEREP is more of an amplifier
than anything else).
DEXJK (I have no idea) Etherjack -- a connection box for mounting
cable connectors.
DEMPR MultiPort Repeater -- repeats Ethernet signals from/to
eight (hence "multiport") thinwire Ethernet segments.
Usually used as an adapter from normal thick-wire Enet
to thin-wire Enet, but can be used standalone in an
all thin-wire environment.
DELNI Local Network Interconnect -- connects upto eight nodes
to form a local Enet. Also acts as a concentrator to
allow eight nodes to share a single tap on Enet.
DESTA STation Adapter -- adapter used with thinwire Enet to
connect nodes which are not thin-wire ready (some of DEC's
newer products are designed for use with thin-wire Enet,
the DESTA is for those that are not so designed).
DECOM (no idea) Broadband Ethernet Transceiver
DEFTR Frequency TRanslator -- Used in single cable broadband
networks to translate the transmit frequency to the
receive frequency.
There are several others, as well as a few that don't begin with "DE"
(like the DECservers, DSRVA and DSRVB). For more info, get a copy of
DEC's "Networks and Communications Buyer's Guide" (the network catalog)
from your salesman.

Reply-To: <LEICHTER-JERRY@YALE.ARPA> Actually, my understanding was that the L in DELUA stood for LANCE (the (AMD?) chip set used in the device). I suspect, however, that there is no "right" answer, and that several diffe- rent interpretations of the almost-acronym have been made right from the beginning of the project. -- Jerry -------
