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)
•Channelizedinterfaces 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
•Innovativeswitch fabric design supports virtual output queues (VoQs)that eliminate head-of-line blocking (HOLB) and
increaseoverall system efficiency and supports partial fulfillment for multicast trafficwhere replication of multicast traffic
is performed by the switch fabric.
•Distributedarchitecture 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
unicastand multicast traffic that fills SONET/SDH transmission facilities to capacity, ensuring best return on investment
on expensive bandwidth
