Not necessarily, sometimes there are 2 PHYs so that they can be switched over if a cabling fault is detected. There will also be the systems where the 'internal' PHY isn't used because of specific (non-standard) media requirements. I'm also not exactly sure what happens when MII crossover is used to directly connect 2 MAC units on the same PCB. David -- David Laight: da...@l8s.co.uk
