XAUI signal detect - D2.0 comment 930
The XAUI signal detect issue needs clarification. Signal detect was added to
draft D2.1 of Clause 47 in response to the Task Force resolution of comment
#930 against draft D2.0. Upon review, the editors believe there may have
been misunderstanding between the commenter's suggested remedy, the Task
Force's response, and/or the Editors' implementation of that response. The
Task Force Chair has recommended that the resolution of the comment be
formally reconsidered at the March meeting to eliminate any and all
confusion.
Please come to the Plenary meeting next week prepared to discuss XAUI signal
detect. We will need to fully discuss and formally decide on this comment
before going to Working Group Ballot on the closing day. There have been
three proposals discussed on the reflector:
1. Add a new signal detect wire to the XAUI interface. This was the
commenter's original intent.
2. Monitor the existing XAUI signals for loss-of-signal. This was the
editors' implementation in D2.1.
3. Do not add any new functionality to XGXS/XAUI. Rely on existing in-band
LF signaling.
Further reflector discussion is appropriate, particularly if there is an
proposal I have overlooked or misrepresented. Thank you all for you effort
on this and all the XAUI issues.
