What are the voltage ranges for Ethernet signal levels and where can I get a reference and list without paying?

 

What are the voltage ranges for Ethernet signal levels and where can I get a reference and list without paying?

Really? Wikipedia.

Thanks joeyd999, I saw in Wikipedia that the signal level is +/-2.5 V which I assume is the nominal. I know this information is probably specified in the IEEE 802.3 standard but I don't have access to this. Is there anywhere else this info. is officially documented?
