The following sections discuss XSBI, PCS, XGMII, and XAUI.
XSBI
One of the blocks of 10-Gigabit Ethernet is the XSBI interface. XSBI is the
interface between the PCS and the PMA sublayers of the PHY layer of the
OSI model. XSBI supports two types of PHY layers, LAN PHY and WAN
PHY. The LAN PHY is part of 10GBASE-R, and supports existing
Gigabit Ethernet applications at ten times the bandwidth. The WAN PHY
is part of 10GBASE-W, and supports connections to existing and future
installations of SONET/SDH circuit-switched access equipment.
10GBASE-R is a physical layer implementation that is comprised of the
PCS sublayer, the PMA, and the PMD. 10GBASE-R is based upon
64b/66b data coding. 10GBASE-W is a PHY layer implementation that is
comprised of the PCS sublayer, the WAN interface sublayer (WIS), the
PMA, and the PMD. 10GBASE-W is based on STS-192c/SDH VC-4-64c
encapsulation of 64b/66b encoded data.
construction of these two PHY layers.
