Warnings.
1.1 Cisco DSL Product Family
The Cisco 6200 is part of a family of digital subscriber line (DSL) products that provide end-to-end
service, carrying data between the subscriber’s home or office, the telephone central office (CO), and
the networks beyond. The Cisco 6000 family includes the following members:
The Cisco 6200 DSLAM is a CO-grade multiplexer that supports up to 80 asymmetric digital
subscriber line (ADSL) ports. The Cisco 6200 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 the enterprise intranet.
ADSL customer premises equipment (CPE) devices, which reside at the subscriber site
connected to PCs or routers, modulate data so that it can travel over telephone lines to the Cisco
6200 DSLAM at the CO. CPE devices in the Cisco DSL product family include the Cisco 675
and the Cisco 605.
The Cisco 6200 Manager is an SNMP-based element management application that provides
configuration, monitoring, and management support. The Cisco 6200 Manager offers a graphical
user interface and runs under Windows NT 4.0 and higher. A separate console interface to the
Cisco 6200 DSLAM provides command line access to all management services.
ADSL plain old telephone service (POTS) splitters, or voice filters, located both at the subscriber
premises and at the CO, support simultaneous voice and data transmission. (If a subscriber is
using a telephone line for data only, the POTS splitter connection is not required.)
