DSLAM Overview

The Cisco 6260 is a multiservice DSL access concentrator designed for worldwide markets and customers including Post, Telephone, and Telegraph (PTTs), competitive local exchange carriers (CLECs), and multitenant-dwelling unit (MDU) service providers.

The Cisco 6260 provides a fully redundant European Telecommunication Standards Institute (ETSI) platform with the capability to support up to 240 DSL modems per shelf (120 using four-port line cards) and up to 3120 ports per system (1560 using four-port line cards) using advanced, fair-service subtending capabilities.

Initial DSL line-card options include ANSI-compliant T1.413 Issue 2 and International Telecommunication Union (ITU) compliant G.992.2 (G.lite) with plans for symmetrical single-line digital subscriber line (SDSL) offerings in the future. The Cisco 6260 also includes optional support for analog voice telephony or plain old telephone service (POTS) via optional POTS splitter equipment supplied through Cisco partners.
