1.4.193 End-of-Stream Delimiter (ESD): Within IEEE 802.3, a code-group pattern used to terminate a normal data transmission. For I OOBASE-T4, the ESD is indicated by the transmission of five predefined ternary code-groups named eopl-5. For IOOBASE-X, the ESD is indicated by the transmission of the code-groupiT/R. For I OOBASE-T2, the ESD is indicated by two consecutive pairs of predefined PAM5x5 symbols (see Table 32-15), which are generated using unique Start-of-Stream Delimiter (SSD)/ESD coding rules. For 1000BASE-T, the ESD is indicated by two consecutive vectors of four quinary symbols as specified in Table 40 1. For IOOBASE-TI, the ESD consists of three code-groups as defined in 96.3.3.3.5. (See IEEE Std 802.3, Clause 22, Clause 23, Clause 32, and Clause 40. and Clause 96.)
1.4.326 Physical Coding Sublayer (PCS): Within IEEE 802.3, a sublayer used in certain port types to couple the Media Independent Interface (MI!), Gigabit Media Independent Interface (GMII) or 10 Gigabit Media Independent Interface (XGMII) and the Physical Medium Attachment (PMA). The PCS contains the functions to encode data bits for transmission via the PMA and to decode the received conditioned signal from the PMA. There are several PCS structures. (For example, See IEEE Std 802.3, Clause 23, Clause 24, Clause 32, Clause 36, Clause 40, Clause 48, Clause 49, and Clause 82. and Clause 96.)
1.4.327 Physical Layer entity (PHY): Within IEEE 802.3, the portion of the Physical Layer between the Medium Dependent Interface (MDI) and the Media Independent Interface (MI!), Gigabit Media Independent Interface (GM II) or 10 Gigabit Media Independent Interface (XGMII), consisting of the Physical Coding Sublayer (PCS), the Physical Medium Attachment (PMA), and, if present, the WAN Interface Sublayer (WIS) and Physical Medium Dependent (PMD) sublayers. The PHY contains the functions that transmit, receive, and manage the encoded signals that are impressed on and recovered from the physical medium. (For example, See Clauses 23 to 26, Clause 32, Clause 36, Clause 40, Clauses 48 to 54, Clauses 58 to 63, Clause 65, Clause 66, and Clauses 82 to 89. and Clause 96.)
1.4.328 Physical Medium Attachment (PMA) sublayer: Within 802.3, that portion of the Physical Layer that contains the functions for transmission, reception, and (depending on the PHY) collision detection, clock recovery and skew alignment. (For example, See IEEE Std 802.3, Clauses 7, 12, 14, 16, 17, 18, 23, 24, 32, 36, 40, 51, 62, 63, 66, and X3, and Clause 96.)
1.4.353 receiver training: Within IEEE 802.3, a start-up routine in 100BASE-T21 and 1000BASE-T. and
100BASE-T1 used to acquire receiver parameters and synchronize the scramblers of two connected Physical
Layers (PHYs).
1.4.363 retraining: Within IEEE 802.3, the process of re-acquiring receiver parameters and synchronizing the scramblers of two connected IOOBASE-T22 Pl-IY or I000BASE-T. or IOOBASE-TI PHYs. See: receiver training, blind mode.
1.4.390 Start-of-Stream Delimiter (SSD): Within IEEE 802.3, a pattern of defined codewords used to delineate the boundary of a data transmission sequence on the Physical Layer stream. The SSD is unique in that it may be recognized independent of previously defined code-group boundaries and it defines subsequent code-group boundaries for the stream it delimits. For 1 OOBASE-T4, SSD is a pattern of three predefined sosb code-groups (one per wire pair) indicating the positions of the first data code-group on each wire pair. For 1 OOBASE-X, SSD consists of the code-group sequence /J/KI. For I OOBASE-T2, the SSD is indicated by two consecutive pairs of predefined PAM5x5 symbols (±2, ±2) (±2, 0) which are generated using unique SSD/ESD coding rules. For I000BASE-T, the SSD is indicated by two consecutive vectors of four quinary symbols as specified in Table 40—1. For IOOBASE-TI. the SSD consists of three code-groups. as defined in 96.3.3.3.5.
