[EFM-Copper] Conference Call of 23 Oct 2003
Barry, All,
I've prepared new text for Table 62B-1 with the changes proposed during
last week's conference call, and uploaded it to the following URL:
http://www.ieee802.org/3/efm/public/nov03/copper/62Bd2_2CMPR1.pdf.
To support the test cases which have UPBO disabled, I will include the
following comment with my recirculation ballot:
---------
CLAUSE 62 / SUBCLAUSE 62.3.4.4 / PAGE 416 / LINE 40
COMMENT (T):
The sentence "Only one UPBO mode shall be supported as described below"
seems to preclude the possibility of disabling UPBO, which would be useful
for testing purposes (in fact, it is implicitly required by the presence
of test cases in Annex 62B which have "UPBO off").
SUGGESTED REMEDY:
Replace this sentence with:
"It shall be possible to temporarily disable UPBO for performance testing
purposes (as required by Annex 62B). In normal operation, only one UPBO
mode shall be supported as described below:"
Add a sentence at the end of subclause 62A.3.4:
"The 10PASS-TS PHY shall additionally allow a profile value of `0' to be
selected, which indicates that UPBO is to be disabled."
Add a 1-bit Enable UPBO register to Clause 45, and document its use in
62A.4.
---------
Regards,
Michael
