Barrington-Il™ — 24 × 10/100/1000 and 2 × 10G Ethernet MAC with SPI-4.2 and XAUI Host Interfaces
Schaumburg-Il™ — 12 × 10/100/1000 and 1 × 10G Ethernet MAC with SPI-4.2 and XAUI Host Interfaces
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
1.2 V core power supply
1.8 V and 2.5 V interface power supply
