An ethernet tranceiver is a far cry from a modem, and is a lot simpler, but it isnt quite pure digital. I believe that EtherNet does colision detect by measuring the DC level on the coax - If one person is using it, the dc level is about X. If two people are trying to transmit at once, it deviates from X. A tranceiver has to be pretty sneaky since X will vary depending on how far away from this tranceiver the station that is transmitting is. A person from MIT recently gave a talk at Stanford advocating ringnets over ethernets for this (simplified analog electronics), amoung other reasons...
