The DW4020 terminal is a self-hosted, stand-alone unit that provides an integrated broadband LAN solution to Windows, UNIX, Linux, Mac, and other platforms running IP over Ethernet. The DW4020 is completely self-contained, requiring no external PC to host any functions. It performs many of the functions of a typical IP router, thereby eliminating the need for a separate external router. Router functions performed by the unit include IP routing using RIPV1, RIPV2, or static IP addresses, DHCP Server (assignment of IP addresses on the local LAN), Network Address Translation (NAT), and Firewall using filters.

Key features include:

• Ethernet-based

• Operating system- (OS) independent

• Scalable

• Self-hosted

• Stand-alone terminal

The DW4020 terminal can achieve a receive throughput of 2.0Mbps or more over the satellite per TCP session with an aggregate throughput of greater than 6.0Mbps. In addition, by implementing the Hughes Performance Enhancement Proxy (PEP) feature, the number of TCP handshakes is reduced and the user data is compressed. This feature minimizes latency over the space link and accelerates the throughput performance so that data can be delivered quickly to the user.

The DW4020 terminal provides broadband access to multiple users connected to the same satellite terminal and supports two-way connectivity between the remote units and the World Wide Web. Adding new remote units is a simple task with this scalable solution. As a business grows, terminals can be quickly installed at new locations.

With DIRECWAY, corporate intranets can be extended to remote locations without raising concerns about security. The DIRECWAY network incorporates multiple security mechanisms, conditional access, and encryption to ensure the privacy of all your information.
