In Phy layer
1) PCS (Physical Coding Sublayter) - Performs autonegotiation and coding such as 8b/10b encoding.
2) PMA (Physical Medium Attachment Sublayer) - Perform PMA framing, octet synchronization and detection and scrambling/descrambling.
3) PMD (Physical Medium Dependent Sublayer) This is sublayer consists of a transceiver for the physical medium.
