The 6519 ADSL2+ family of endpoints deliver the required performance for multimedia applications at very competitive price points. The 6519 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 DZS 6519 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).

The 6519 ADSL2+ series endpoints integrates the 802.11N WiFi access point is suitable for bandwidth intensive applications while allowing easy installation without wiring for high speed internet.

DELT or Dual End Loop Test, is a feature that is present in the 6519 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.

Default settings make for a quick and easy installation that doesn’t require any configuration.

The modem, when operating in router mode, supports DHCP Server/Relay/Client, NAPT, as well as RIP, dynamic routing, port forwarding, and static routing. For security, firewall functions, PAP/CHAP authentication and IP filtering are supported.
