45.2.1.20.la 200GBASE-ER4 ability (1.23.6)
When read as a one, bit 1.23.6 indicates that the PMAJPMD is able to operate as a 200GBASE-ER4
PMA/PMD type. When read as a zero, bit 1.23.6 indicates that the PMA/PMD is not able to operate as a
200GBASE-ER4 PMA/PMD type.

PMAJPMD type. When read as a zero, bit 1.23.2 indicates that the PMAIPMD is not able to operate as a
200GBASE-SR4 PMA/PMD type.
45.2.1.20.6 200GBASE-CR4 ability (1.23.1)
When read as a one, bit 1.23.1 indicates that the PMAJPMD is able to operate as a 200GBASE-CR4
PMA/PMD type. When read as a zero, bit 1.23.1 indicates that the PMA/PMD is not able to operate as a
200GBASE-CR4 PMAJPMD type.
45.2.1.20.7 200GBASE-KR4 ability (1.23.0)
When read as a one, bit 1.23.0 indicates that the PMAJPMD is able to operate as a 200GBASE-KR4
PMA/PMI) type. When read as a zero, bit 1.23.0 indicates that the PMAIPMD is not able to operate as a
200GBASE-KR4 PMAJ’PMD type.
45.2.1.21b.1 IOOGBASE-SR2 ability (1.26.9)
When read as a one, bit 1 .26.9 indicates that the PMA/PMD is able to operate as a 1 OOGBASE-SR2
PMA/PMD type. When read as a zero, bit 1.26.9 indicates that the PMA/PMI) is not able to operate as a
IOOGI3ASE-SR2 PMA/PMD type.
45.2.1.21b.2 IOOGBASE-CR2 ability (1.26.8)
When read as a one, bit 1.26.8 indicates that the PMA/PMD is able to operate as a IOOGBASE-CR2
PMAJPMD type. When read as a zero, bit 1.26.8 indicates that the PMAIPMD is not able to operate as a
IOOGBASE-CR2 PMAJPMD type.
45.2.1.21b.3 IOOGBASE-KR2 ability (1.26.7)
When read as a one, bit 1.26.7 indicates that the PMA/PMD is able to operate as a IOOGBASE-KR2

IOOGBASE-KR2 PMA/PMD type.
45.2.1.21b.4 IOOGBASE-DR ability (1.26.3)
When read as a one, bit 1.26.3 indicates that the PMA/PMD is able to operate as a IOOGBASE-DR
PMA/PMD type. When read as a zero, bit 1.26.3 indicates that the PMA!PMD is not able to operate as a
IOOGBASE-DR PMA/PMD type.
122.2 Physical Medium Dependent (PMD) service interface
Change the first paragraph of 122.2 asfollowx:
This subclausc specifies the services provided by the 200GBASE-FR4, 200GBASE-LR4, 200GBASE-ER4. 400GBASE-FR8, and 400GBASE-LR8. and 400GBASE-ER8 PMDs. The service interfaces for these PMDs are described in an abstract manner and do not imply any particular implementation. The PMD service interface supports the exchange of encoded data between the PMA entity that resides just above the PMD, and the PMD entity. The PMD translates the encoded data to and from signals suitable for the specified medium.IEEE Std 802.3cn pdf download.
