Hi,

sorry if I abuse of this group for a partially unrelated question...

I am having a hard time in finding cheap Ethernet repeaters with
BNC ports, whereas 10 Mb/s HUBs with 10BaseT RJ45 ports are now
available for about $15/port.  Is it possible to connect the AUI
port of a BNC transceiver to the Tx/Rx pairs of an RJ45 port and
make the connection work ? (of course with an external power supply)

I am asking because quite often I have seen RJ45 "transceivers" to be
connected to the AUI port which are a block of plastic with
only wires inside. The collision pair is evidently left unconnected,
but this might work just because the AUI port on those ethernet cards
is special.

I am actually thinking of something different (and perhaps less
critical), since the 10baseT port must be able to sense collisions
via A the Rx/Tx pairs.

	Thanks
	Luigi
