George,
I believe the text below was accepted as resolution to comment 115.
Brett
replace the text of 149.3.2.2.14 with the following:
"The payload of the PCS PHY frame tx_encoded<3599:0> is scrambled to tx_scrambled<3599:0> with an additive scrambler. Two scrambler bits per symbol are generated from the side-stream scrambler defined in 149.3.4. The first (LSB) bit is
DS_n[0] equal to Scr_n[0] defined in 149.3.4. The second (MSB) bit is DS_n[0] equal to Scr_n[3] XOR Scr_n[8].
DS_n[0] and DS_n[1] are applied as additive scrambler sequences to incoming data bits D_n[0] (LSB) and DS_n[1] (MSB) to generate two scrambled data bits {A, B} as follows:
A = DS_n[0] XOR D_n[0]
B = DS_n[1] XOR D_n[1]. "
(_n denotes subscript)

Thanks, Brett – this seems reasonable – where was the reference to DS_n[0] and DS_n[1]? (I can’t find it). The ones I was referring to are the Scr_n[0], Scr_n[3] and Scr_n[8] (without the extra comma in the subscript) which relate to
the nomenclature in Figure 149-10 and equation 149-8 used for the side stream scrambler.

Natalie,
I suggest changing Scr_n,0 and Scr_n,1 to DS_n[0] and DS_n[1] and change d_n,0 and d_n,1 to D_n[0] and D_n[1] because those terms were accepted as the text for the data scrambler section.

A very minor thing on the nomenclature – the scrambler bits are Scrn with a capital S, not scrn all lower case.

Colleagues,
Please look at the proposed changes to Figure 149-7 based on the decision in Comment #115 to make this a block diagram and move it to Section 149.3.2.2.
Please plan to request any desired changes tomorrow.
Thanks,
Natalie
