 DirecWay™ - Bringing Low-Cost Telephony to a Wide Range of Markets

The DW6040 Voice Appliance is a state-of-theart telephony device that provides efficient telephone and fax connectivity via the DIRECWAY® network. The DW6040 is an excellent solution for enterprise or rural telephony markets where reliable low-cost telephone service is needed.  The DW6040 provides up to four toll-quality telephone or Group 3 facsimile channels via satellite to the PSTN or, optionally, to a Voice over IP (VoIP) network.

The DW6040 is a simple add on to the DIRECWAY terminal, which provides the transport for carrying telephony traffic via satellite to the DIRECWAY NOC. A voice gateway at the NOC provides connectivity to the PSTN. The standard H.323 protocol suite is used between the DW 6040 and the gateway for call setup and teardown. The  DW6040 Voice Appliance offers superior telephony quality using the G.729a 8 Kbps voice codec with echo cancellation, voice activity detection, and comfort noise generation. Facsimile calls are supported using the T.38 fax over IP protocol to rates of 9.6 Kbps. The DW6040 voice appliance also supports a flexible dialing plan.

DW6040 Voice Appliance provides telephone access via the DIRECWAY network

The service is delivered via a terminal adaptor that is added between the equipment Hughes already provides for data and the phone. The terminal adaptor plugs into the Hughes satellite transmitter/receiver on one side and into a standard analog phone on the other. Both boxes are provided by Hughes, which includes proprietary technology to give voice traffic priority over data to ensure good voice quality.

Voice is transmitted using the G.729 codec, which reduces the voice bandwidth to about 12 kilobits per second, Hughes says. Calls made over the service from Africa, the Middle East or Europe are transmitted via Eutelsat W1 or Panamsat >= 10 and aggregated at Hughes' network operating center in Griesheim, Germany. From there they are terminated via the Net2Phone network. We haves a similar setup for the Americas.

The DW6040 is optimized for use with the DIRECWAY system. As each call is initiated, the DW6040 automatically reserves bandwidth through the DIRECWAY system and the associated voice stream is prioritized to ensure end-to-end toll-quality transmission of the call. The DIRECWAY system also facilitates short call setup times – typically less than four seconds and low end-to-end delay. Transmission efficiency is improved by compressing the voice packets. The DIRECWAY NOC equipment routes the voice calls to the PSTN via an H.323 voice gateway. The voice gateway performs the conversion from the H.323 protocol and the PSTN signaling. The voice gateway provides an E1interface to the PSTN. Multiple voice gateways may be configured at the NOC. A gatekeeper provides the address resolution between the DW6040 and multiple voice gateways.

The DW6040 is managed by the HNS Vision® Network Management System (NMS), which provides monitoring and control of the voice appliance, as well as the DIRECWAY terminal. Downloads of software and configuration parameters are also performed by the NMS.

Are you sick of paying exorbitant amounts to call Wisconsin, Macedonia, or Middle East?

The new service is designed to provide long distance IP voice services to remote and underserved areas of the world, enabling end users to place calls anywhere in the world at competitive prices. The end users are expected to be enterprises, and providers of voice and data services to the public, such as Internet cafes and kiosks.

Net2Phone's VoIP telephony interface has been folded into HNS' DW 6040 voice applianceVoIP Soft Phone terminal. The device enables subscribers of HNS' Direcway service to access Net2Phone's international long-distance service.

Previous satellite telephony systems delivered spotty performance because systems couldn't differentiate between voice and data packets. But this offering identifies voice packets and sends them over the networks first. It will be sold as an add-on and is expected to be popular in remote areas in North America, Eastern Europe, Latin America, Middle East, Africa and other markets where land-based telecommunications and Internet infrastructure is under-developed.

The product will costs approximately $400 US for a four-port router. HNS collaboration with Net2Phone extends the reach of affordable VoIP international calling worldwide, wherever there is satellite coverage. Net2Phone's core competency has always been to layer voice over data networks. Satellite, especially in conjunction with new DIRECWAY voice appliance, is the next frontier in data networks that can be powered with voice.

DW6040 Voice Over IP

Make voice calls while you surf

With DIRECWAY VoIP, you can surf, send and receive emails, download files and make a voice call, all at the same time.

Every time you make or receive a call, software converts your speech into digital information that is sent via the Internet. This is known as Internet telephony or VoIP (Voice over Internet Protocol). When that information nears its destination, it is converted back to speech—so it is just like a normal phone call! As the bandwidth you are using can deliver both Internet and voice traffic, sophisticated networking tools ensure that all your voice calls are given prioritised bandwidth access over other Internet traffic.

Communicate anywhere, anytime with DIRECWAY VoIPVoice Over IP

Regardless of the country in which you set up your DIRECWAY VoIP account, when someone dials your DIRECWAY phone number, your phone will ring. For example, all numbers are local U.S. numbers, so should you set up your service in Spain, when someone dials your phone number, it rings at your home in Spain.

VoIP Net2PhonePowered by Net2Phone, a market leader in the provision of Internet telephony services, DIRECWAY VoIP allows you to take advantage of market-competitive rates for all your calls. In addition, as calls are routed over the Internet before breaking out onto the traditional fixed network, call costs are often less than if the call had originated and remained on a traditional telephone network.
