PRS64Gu

• 16 input ports and 16 output ports (one chip); or 32 input ports and 32 output ports (two chips)
• 40-Gbps (one chip) or 80-Gbps (two chips) aggregate user bandwidth
• Up to four GE or one OC-48c per port, or one 10GE or one OC-192c per group of four ports
• Quality of Service (QoS) with four levels of traffic priority and programmable flow control thresholds
 • Packet lossless switchover capability and efficient multicast (replication at sending)
• Industry standard CSIX-L1 interface to Network Processors or Traffic Managers
 • Embedded high-speed serial links at 2.5 Gbps for simpler wiring, compact switch board design, and common wiring rules across multiple PRS-based switches (PRS 64Gu, Q-64G, and so on)
• End-user evolution from/to other PRS switch cores, using the same line adapters (investment protection)
