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

KEY SPECIFICATIONS:

` 1.2 V core power supply

` 1.8 V and 2.5 V interface power supply

` 10 W power dissipation

` 27 mm × 27 mm, 672-pin, flip chip ball grid array (FCBGA) package
