[EFM] Re: EFM OAM on Preamble

[Date: 11/22/2001  From Seto]


I asked Hiroshi a similar question regarding 100BASE-X case.  
RX_DV can be asserted any time before SFD. 
Hiroshi's answer was  "I fully understand which sections they 
are defined."  I assumed he intend to change exsiting preamble 
reception mechanism in IEEE802.3 for EFM.  Is that so, Hiroshi?
