1.1 Introduction to the Cisco 6260 System
The Cisco 6260 system is part of the Cisco DSL product family that provides end-to-end service by
carrying voice or data traffic, or both, between a subscriber's home or office, a telephone central office
(CO), and various networks beyond. The Cisco 6260 system sends and receives subscriber data (often
Internet service) over existing copper telephone lines, concentrating all traffic onto a single high-speed
trunk for transport to the Internet or a corporate intranet. Before traveling over telephone lines to the
DSLAM at the CO, data is modulated by xDSL customer premises equipment (CPE) devices, which are
connected to PCs or routers at the subscriber site.
The Cisco 6260 system may include the following components:
