BLOCK DIAGRAM:

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
