The T640 Core Router is a complete routing system that provides Gigabit Ethernet,
SONET/SDH, and other high-speed interfaces for large networks and network applications,
such as those supported by Internet service providers (ISPs).
Application-specific integrated circuits (ASICs) are a definitive part of the router design;
these ASICs enable the router to achieve data forwarding rates that match current
fiber-optic capacity.
The router accommodates up to eight Flexible PIC Concentrators (FPCs), which can
each be configured with a variety of network media types—altogether providing up to
128 SONET/SDH OC48/STM16, 32 SONET/SDH OC192/STM64, or 128 Gigabit Ethernet
ports for the router. In a standalone configuration, the router's maximum aggregate
throughput is 320 Gbps, full duplex.
The router is a modular, rack-mountable system. Two routers can be installed in one
standard, 78-in. telco rack.
