Figure 18-2: Cisco 12008 Series, Front View
The Cisco 12000 Series products are built to meet the bandwidth, performance, services and reliability requirements of
today’s IP core backbones.
Scalable Bandwidth
• Modular, multigigabit crossbar switching fabric allows bandwidth to scale in either 40Gbps (12008), 60Gbps (12012),
80Gbps (12016), 200Gbps (12410) or 320Gbps (12416).
• High density, high speed interfaces ranging from DS1 to OC-192c/STM64c, that can be easily added as needed.
• Packet over SONET/SDH interfaces at 155 Mbps (OC3/STM1), 622 Mbps (OC12c/STM4c), 2.5 Gbps (OC48c/
STM16c), and 10Gbps (OC192c/STM64c) data rates.
• Asynchronous Transfer Mode (ATM) interfaces at 155 Mbps (OC3/STM1) and 622 Mbps (OC12c/STM4c) data rates
• LAN interfaces 1 Gbps (Gigabit Ethernet) and others to follow
• Frame based interfaces (PPP, Frame Relay) at 45 Mbps (DS3), 155 Mbps (OC3/STM1), 622 Mbps (OC12c/STM4c)
• Channelized interfaces at 622 Mbps (OC-12) channelized to 45 Mbps (DS-3), 622 Mbps (OC-12/STM-4) channelized to
155 Mbps (OC-3/STM-1), and 45 Mbps (T3) channelized to DS-1 (1.5Mbps)
• Scalable Performance
• Innovative switch fabric design supports virtual output queues (VoQs) that eliminate head-of-line blocking (HOLB) and
increase overallsystem efficiency andsupports partialfulfillment for multicasttrafficwhere replication ofmulticast traffic
is performed by the switch fabric.
• Distributed architecture delivers scalable Layer 3 switching performance through intelligent line cards that can be added
incremental interfaces are required
• Micro-programmable application specific integrated circuits (ASICs) based queuing provides line rate forwarding for
unicast and multicast traffic that fills SONET/SDH transmission facilities to capacity, ensuring best return on investment
on expensive bandwidth
