RE: [802.3ae] Gig Ethernet over SONET

David, et al,

X.86 is another standard for "Ethernet over SONET" that is specific to Ethernet and does not include RPR and other protocols and does not use modifications of the IPG.  X.86, "Ethernet over LAPS", was approved at ITU-T SG7 last March.  I have attached to approved drafts involved with that standard.  X.86 is a very simple mapping technology that has proven to be very reliable in testing. 

Thank you,
Roy Bynum

The draft standard being developed in ANSI T1X1.5 is available at the URL below. This
work has been underway there since fall 1999. That draft will likely form the basis for
the recently initiated effort in ITU-T SG15 Q.11.

The document is T1X1.5/2001-024R4. The filename is 1x150244.

Subject: [802.3ae] Gig Ethernet over SONET

Appreciate any information or pointers on Ethernet over SONET?
Some one mentioned that there is an ITU standard which specifies
the transport Ethernet as a concatenated signal in the SONET
