Hello - I have a question on the Auto MDI/X feature on 1000BASE-T Gigabit Ethernet Copper.
Does it work using same concepts as in Fast Ethernet 100B-TX? In100BASE-TX it used 2 pairs whereas in 1000BASE-T used 4 pairs. ?
For Fast ethernet supporting Auto MDIX(when Auto Nego is Enabled), the PHY switches its transmitter to RD+- and its receiver to TD+-, alternatively till a link is establised with the link partner.
How does it work for Gigabit Ethernet copper 1000BASE-T ? Is it similar
Any pointers suggestions would help .
Also please if you could let me know the IEEE specifications Clause which defines this for Fast ethernet and Gigabit Ethernet Copper .
thanks and Best Regards Kott
