DIRECWAY® is a family of broadband satellite solutions brought to you by Hughes Network Systems (HNS), the global market leader in providing satellite products and services to enterprises, government, and consumers. DIRECWAY satisfies the increasing demand for bandwidth by offering a variety of high-speed multimedia hardware, software, and service solutions.

DW7700 Satellite Router is the latest in the Hughes line of business satellite internet solutions. This unique satellite internet unit combines some of the best features of other DirecWay systems into a single device which is ideal for business applications. The DW7700 has multiple RJ45 Ethernet ports, not unlike the DW4020. It has a serial port (commonly used in business credit-card processing applications) like the DW6030, and has the high performance & new technology of the DW7000.

Internally the DW7700 has the same speed capabilities like the DW7000. For the average home user there would be no benefit to spending the extra money for a DW7700, but businesses should find it a versatile modem. The DW7700 even has a phone-line backup port, as businesses would never want to be "down" for any reason.

The DW7700, part of HNS' DW7000 family, is a high-performance broadband satellite router designed to provide high-speed access for large enterprise, government, and small/medium enterprise (SME) markets. Recognizing the worldwide demand by enterprises for ever increasing amounts of bandwidth and the ability to support many simultaneous users, the DW7700 has been designed to provide unsurpassed performance for even the most bandwidth intensive applications. With support for two simultaneous LAN subnets, the DW7700 has the flexibility to handle new enterprise IP networking requirements. Further, the DW7700 supports integrated serial connectivity, thus providing the ideal solution for bridging legacy applications into an IP environment.

The DW7000 enables applications such as:

The DW7700 operates with all DIRECWAY systems and uses the industry standards DVB-S and DVB-S2. As a result, the DW7700 can be easily configured to support a wide range of downstream data rates by selecting different modulation, symbol, and FEC coding rates. The downstream is scalable up to 90 Mbps and the upstream return channel is scalable up to 1.6 Mbps. The DW7700 provides an integrated broadband LAN solution to Windows®, UNIX®, Apple® Macintosh®, and other platforms running IP over Ethernet.

The power of the DW7700 allows the same platform to scale as the need for higher-speed business applications grows, protecting the customer's investment well into the future. The DW7700 also coexists with prior DIRECWAY generations ensuring existing customers' investment is protected.

The DW7700 receives and transmits data over the satellite via the DIRECWAY Network Operations Center (NOC). Security is ensured through DES encryption and an integrated conditional access. The DW7700 also supports HNS' innovative VPN Accelerator technology to ensure broadband speeds are maintained even when using IPSec VPN clients from market leaders such as Cisco, Nortel, and Check Point.

The DW7700 satellite router passes IP data packets to and from any IP device on the LAN and has much of the functionality of an IP router. The DW7700 incorporates HNS' advanced Performance Enhancing Proxy (PEP) feature, which increases throughput performance and maximizes the user's experience and satisfaction. The DW7700 also supports HNS' TurboPage® feature, providing HTTP acceleration for lightning fast browser performance and advanced Quality of Service features to ensure that applications get the priority and bandwidth they require.

The integrated serial port with protocol processing to support SDLC, X.25, or XPAD (asynchronous data) protocols means the DW7700 can be used to support legacy applications such as Automatic Teller Machines (ATM) or credit card devices.

An integrated broadband LAN solution to Windows®, UNIX®, Apple® Macintosh®, and other platforms running IP over Ethernet. An integrated V.90 modem provides the ability to use the optional automatic dial backup capability through a public-switched terrestrial network for virtual 100 percent availablity.

Internally, the DW7700 and DW7000 look about the same, as they are manufactured using the same circuit board. The rear of the DW7700 is where the big differences are. Note above the Serial, Phone, and secondnd LAN ports, none of which are on the DW7000 satellite modem.


The DW7700 (alike the DW7000) features an internal status and diagnostics menu, the "System Control Center", which hosts a large variety of statistics, logs, and modem functions. The DW7700 is typically teamed with a .98m or larger satellite dish and a 2-Watt transmitter. While the DW7700 is rated to work with a smaller dish, the larger dishes aquire a more stable signal. Further, the smaller dishes are only equipped with 1-Watt transmitters.

Prices for complete DW7700 systems (dish and modem) vary depending on dish size and transmitter power. Monthly service packages start around $99. The DW7700 offers a service package unavailable to other model systems, and only available to DW7700 systems paired with the 1.2m dish. This package boasts downstream speeds of up to 2500kbps, and upstream speeds up to 1000 kbps. A powerful, but pricey package at around $500. per month. Still, these are speeds never before available to Direcway satellite internet customers, and certainly worth the price to companies needing that level of performance.

Alike the DW7000, DW7700 users are currently seeing speeds very close to the high mark of their subscribed package. The DW7700 is a true 'stand-alone' device, and requires no software or drivers to be installed on the users computer. This allows the DW7700 to be O.S. independent and offer an 'always-on' connection.
