Hie thee to comp.dcom.lans for an extended discussion of 10BASE-T!

Actually, you do NOT want to build an adapter as you will be searching
far and wide for electronic components!  If your terminal server is 
10BASE-T compliant (very doubtful), then you just plug an 8-conductor
cord from the hub to the jack on the terminal server.  Since (I'd bet)
the TS is a 'classic' AUI port, you will need to translate the 10BASE-T
signals into those compatible with the AUI port...terribly complex for
a beginner.  Instead...get an AUI adapter from AT&T or a reseller and
look at the spec for your TS to determine the state of Signal Quality
Error (SQE) and set the AUI adapter to match...and you will have saved
yourself the money and time.
