The host interface can be VSC7344 configured as SPI-4.2, one XAUI, or two XAUI VSC7346 interfaces. Each SPI-4.2 and XAUI host interface uses a SPI-4.2 status channel for flow control. To support the high oversubscription factor, the Barrington-II has a set of advanced QoS features. A P P L I C AT I O N D I A G R A M : 24x 1GbE Line Card Octal Cu PHY When using the SPI-4.2 host interface, both XAUI ports are available for use as 10 gigabit Ethernet line ports. In addition to Barrington-II, Vitesse offers Schaumburg-II (VSC7346), an advanced Ethernet MAC containing 12 10/100/1000 Ethernet ports. It has the same features and functionality as Barrington-II.
