The Cisco 6000 family includes the following members:• The Cisco 6200 DSLAM is a CO-grade multiplexer that supports up to 80 asymmetric digitalsubscriber line (ADSL) ports. The Cisco 6200 sends and receives subscriber data (often Internetservice) over existing copper telephone lines, concentrating all traffic onto a single high-speedtrunk for transport to the Internet or the enterprise intranet.• ADSL customer premises equipment (CPE) devices, which reside at the subscriber siteconnected to PCs or routers, modulate data so that it can travel over telephone lines to the Cisco6200 DSLAM at the CO. CPE devices in the Cisco DSL product family include the Cisco 675and the Cisco 605.• The Cisco 6200 Manager is an SNMP-based element management application that providesconfiguration, monitoring, and management support. The Cisco 6200 Manager offers a graphicaluser interface and runs under Windows NT 4.0 and higher. A separate console interface to theCisco 6200 DSLAM provides command line access to all management services.• ADSL plain old telephone service (POTS) splitters, or voice filters, located both at the subscriberpremises and at the CO, support simultaneous voice and data transmission. (If a subscriber isusing a telephone line for data only, the POTS splitter connection is not required.)
