The 6200 ADSL2+ endpoints, in compact form factor, have been successfully used for residential, business, in-building deployments such as hotel/motel, temporary housing, and dormitory-campus installations for high-speed internet access (HSIA) and video-on-demand services. The Paradyne 6200 ADSL2+ endpoints are easily user-installed. The embedded web-based user interface is designed to simplify ADSL deployment. All products provide an Ethernet connection that is auto-sensing, eliminating the worry about connection cable type (straight-through vs crossover). All units include a built in POTS filter that eliminates the expense of an external filter as well as reduces installation errors. DELT or Dual End Loop Test, is a feature that is present the 621x Family of ADSL2+ CPEs. DELT is primarily used for reactive tests on a loop after a modem has been deployed—either to help troubleshoot a line or to capture a baseline of loop characteristics at the time of installation. Because DELT is a dual-ended test, it requires equipment that supports the DELT feature at both ends of the copper loop. While this prevents DELT from being used on loops where no CPE has yet been deployed, DELT in turn offers a deeper set of loop tests, and can provide very valuable information on the condition of a copper loop. The 6200 endpoint functions as a simple bridge. Default settings make for a quick and easy installation that doesn't require any configuration. The 6211, 6212, and 6218 endpoints, when operating in router mode, support DHCP Server/Relay/Client, NAPT, as well as RIP, dynamic routing, port forwarding, static routing, and ping initiation. For secuirty firewall functions including PAP (Password Access Protocol) and CHAP (Challenge Handshake Authentication Protocol) are supported.
