FEATURES:
` Supports full line rate (24G)
` Expandable to 48 triple-speed ports
` SPI-4.2 or XAUI host interface provides seamless connection to a variety of 10G and next-generation 20G/40G
packet processors
` 10/100/1000M and 10G line ports reduce the number of components needed to build high-density line cards
` 2:1 and 4:1 oversubscription eliminates unused bandwidth at the client interface and fully utilizes shared network
services processor
` Connects directly to 1G copper PHYs, 100M/1G optical SFP modules, and 10G XENPAK/X2 optical modules
` Advanced Quality of Service (QoS) guarantees delivery of differentiated services
` Full RMON 1 statistics and applicable IEEE-802.3 and SNMP statistics provide extensive support for performance monitoring
and billing
