I am trying to build a standalone ethernet transceiver for some ethernet
experiments. I am using the National DP8392 Tranceiver chip. There is a
connection diagram given in the data book and I built one exactly as it
says except that I didn't use a DC-DC converter and a separate 9V supply
is used. However, it doesn't work. I am pretty sure that the wirings are
correct. I check with a CRO and found that it can receive since output
is observed at the receive pair. I couldn't figure out how to test the
transmitting though.

Anyone built that circuit before? Is the circuit given in the data book
correct?  Any tips will be great.
