--Editor's note after Table 61-21 (G.hs options for MCM)

 

Agreed Barry would submit comment to remove note, and add tables based on earlier draft of Clause 62.  Will also include comment to change 2BASE-TL and 10PASS-TS Level 1 bit assignments to those assigned by ITU-T Q4/15 liaison, along with their recommended tones sets for 10PASS-TS.

 

-- 62.2.4.3 R-S settings

 

Scott will submit comment to delete optional values

 

--Editor's note on Page 330 (62.4.4.2.2)

 

Bernard to submit comment to fix n=4, with note that Max. frequency range of 12 MHz will restrict usable tones when 8 KHz spacing is used.  Also note upstream/downstream distinction.

 

--Editor's note on Page 332 (62.4.4.2.2)

 

Michael will check ETSI VDSL spec. and make appropriate comment.

 

--Editor's notes on Page 333

 

Barry to submit comment fixing Bmax_d and Bmax_u equal to 15.

 

Michael will comment that sections 62.4.4.4 should reference Part 1 of Committee T1 specification

 

--Annex 62B content

 

Hugh will submit comment with strawman table with subset of profiles and loops specified, but with TBD performance numbers.  Implementers will come prepared with numbers “in their back pocket” for discussion and agreement at meeting.

 

--Annex 62C (MCM section)

 

Chair encouraged comments proposing text for (informative) sections 62C.4.2 and 62C.5.2.

 

--Section 45.5 (registers for MCM) 

 

Ran out of time to discuss in detail.  Chair encouraged comments for this section, and noted subclause 45.4 (registers for SCM) appeared much more complete (hint, hint).

 

Call adjourned at 10:30 AM PDT.
