Although the text in clause 45 for the transmit and receive fault bits has been updated, the
text for the global PMA/PMD fault bit (1.1.7) has not been updated to cover 40/100Gbps
operation.
45.2.1.2.1 currently says :
Fault is a global PMA/PMD variable. When read as a one, bit 1.1.7 indicates that either (or
both) the PMA or the PMD has detected a fault condition on either the transmit or receive
paths. When read as a zero, bit 1.1.7 indicates that neither the PMA nor the PMD has
detected a fault condition. For 10 Gb/s operation, bit 1.1.7 is set to a one when either of the
fault bits (1.8.11, 1.8.10) located in register 1.8 are set to a one. For 10PASS-TS or 2BASE-
TL operations, when read as a one, a fault has been detected and more detailed
information is conveyed in 45.2.1.16, 45.2.1.39, 45.2.1.40, and 45.2.1.55.
SuggestedRemedy
Add change instructions to make 45.2.1.2.1 say :
Fault is a global PMA/PMD variable. When read as a one, bit 1.1.7 indicates that either (or
both) the PMA or the PMD has detected a fault condition on either the transmit or receive
paths. When read as a zero, bit 1.1.7 indicates that neither the PMA nor the PMD has
detected a fault condition. For 10/40/100 Gb/s operation, bit 1.1.7 is set to a one when
either of the fault bits (1.8.11, 1.8.10) located in register 1.8 are set to a one. For 10PASS-
TS or 2BASE-TL operations, when read as a one, a fault has been detected and more
detailed information is conveyed in 45.2.1.16, 45.2.1.39, 45.2.1.40, and 45.2.1.55.

The definition of the "PRBS9 ability" bit requires that PRBS9 generation capability be
provided in both transmit and receive directions even though the PRBS9 pattern is strictly
an optical test pattern. (See line 48)
In order for an optical gearbox PMA to support PRBS9 generation to the optics it would be
required to also provide PRBS9 on the CAUI
SuggestedRemedy
Change the name of 1.307.5 to "Tx PRBS9 ability" and change the description field to
1 = Transmit direction PRBS9 pattern generation supported
0 = Transmit direction PRBS9 pattern generation not supported
Change the paragraph starting on line 47 to
When read as a one, register 1.307, bit 6 indicates that the device supports PRBS31
generation or checking, and register 1.307. In this case, it shall support that test for all of
the generator and checker types that are indicated by the assertion of bits 3:0.
When read as a one, register 1.307, bit 5 indicates that the device supports PRBS9
generation in the transmit direction.
ACCEPT IN PRINCIPLE.
Clause 83 allows PRBS9 generation in both the transmit and receive directions.
Change definition of bits 1.307.0 through 1.307.7 in Table 45-65a Test pattern ability
register so that ability is indicated for each supported permutation separately.
Make corresponding changes in Clause 83.

The Register names of registers 1.308 and 1.309 in this table are swapped.
The clause references are correct.
SuggestedRemedy
change name of 1.308 to "Square wave testing control"
change name of 1.309 to "PRBS pattern testing control"
ACCEPT IN PRINCIPLE.
