[802.3ae] Clarification of the 10GBASE-W ELTE function


FYI: the following contribution to T1X1.5 (written by Tom
Alexander, David Martin, and Steve Gorshe) may be of interest,
as it presents a detailed argument that ELTE can be
realized within existing NEs -- e.g. as a 10GBASE-W line
card -- and does not require a separate external piece of
equipment.  That was exactly the message of the last slide
in the WIS MIB design team's IETF52 presentation (see
illustrating a 10GBASE-W interface on a SONET ADM.

TITLE: Clarification of the 10GBASE-W Ethernet Line Terminating 
Equipment (ELTE) function and its realization within existing SONET 
DESC: This contribution clarifies the issues that have been raised with 
regards to the proposed ELTE function, needed to adapt a 10GBASE-W 
Ethernet WAN-PHY signal to a SONET/SDH STS-192c/VC-4-64c signal. In 
particular, we demonstrate that such adaptation does not need 
additional NEs; that is, the ELTE function can be realized by existing 
NEs, and does not require new equipment to be added to a SONET/SDH
