No the DELNI was a box that allowed 8(?)  hosts to share a single half-duplex ethernet transceiver.   It had ethernet AUI connections for the hosts,  and another for plugging in a transceiver.   Contention was,  of course,  CMSA/CD based.   

I don't recall if you could operate it without a transceiver attached; as an "ethernet in a box".   This might have been something another vendor supported.
