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.

What is the difference between the IP-Access and IP-Connect Services? IP-Access provides a Fast Internet Access Service on a shared basis, with three different data rates up to 2048 kbps downstream and up to 512 kbps upstream. IP-Connect is a service with a dedicated (i.e. non-shared)data rate from 64 kbs to 8 Mbps allocated exclusively to one customer. What are the advantages of LinkStar IP Access compared to terrestrial Internet services? IP Access offers a broadband Internet service which is completely independent from local telco companies. The persuasive bandwidth is comparable and exceeds the performance of DSL and cable modems. The always-on functionality and the fair-use flat rate are other important features. What can I understand by "Fair-Use Flat Rate"? The concept of "Fair-Use Flat Rate" applies to the IP-Access service: The subscription to the service is based on a monthly fee rather than on invoicing for the traffic on a volume basis. However, in order to guarantee a fair access for everybody in the user community sharing a common channel (one or more satellite transponders), excessive consumption (e.g. streaming media or file sharing on a peer-to-peer network for many hours) is not allowed. In case of excessive upload or download volume, the data rate will be temporarily limited and the user will downgraded on the priority level. What are possible applications for the IP-Connect service? IP-Connect can be used in principle for all applications which are based on IP connectivity, including: Internet access, corporate network infrastructure (WAN, VPN), digital video streaming (DVB), distance education, videoconferencing, voice over IP (VoIP). Can I use LinkStar to implement Voice over IP (VoIP)? LinkStar offers the ability to implement VoIP. However, due to the long satellite path, there is an important round loop delay of typically 1.5 seconds. This needs a telephone conversation rather to be simplex, i.e. only one person speaks at a time. Nevertheless, VoIP based on LinkStar can be an attractive alternative in geographical regions with non-existing or poor telephone infrastructure. How do I connect a PC or a Local Area Network (LAN) to the LinkStar terminal? The indoor unit of the terminal provides a 10/100 Mps Ethernet Interface which allows you to directly connect a single computer (via a crossed Ethernet cable) as well as a network hub, switch, router or proxy server. Can I connect the LinkStar terminal to a wireless LAN (W-LAN) network? Yes, trough the Ethernet interface it is possible to connect directly a wireless access point or wireless bridge. No access PC or workstation is needed. How many IP addresses do you provide with each system? In addition to the IP address of the terminal, as an option up to 13 private (static) IP addresses can be provided per station. By attributing these IP addresses to individual PCs it is possible to set-up a small Local Area Network (LAN) without the need of a router. Do you provide public IP addresses? For applications based on the fast Internet access service (IP Access) public addresses are generally not needed. For special applications which would need a public IP address,a group of public IP addresses (4, 8, 16.) can be allocated to each terminal. Is Linux possible as primary Operating System? The LinkStar terminal is an independent station, with no PC needed for operation. Thus the operation system of the computers connected to the LAN is irrelevant, as long as it supports the Internet Protocol (IP). This is the case of all modern operating systems, including Linux and MAC OS. Who can install the system? The terminal has to be installed by a certified installer. Indeed special skills for installing and commissioning are needed, which go well beyond the installation of a satellite reception-only system. Can I become an certified installer? Professionals and resellers successfully completing a one-day seminar can become a certified installer. Prior experience in installing VSAT equipment is highly useful, but not a pre-requisite. Who provides support for LinkStar? TISC provides free e-mail and telephone support for all her LinkStar customers. If needed, exceptionally on-site support is offered at cost.

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' DW6040 voice appliance 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 DW6040, is the next frontier in data networks that can be powered with voice. 

DVB-RCS Topology Star Satellite Communication System-LinkStar

Introduction
    LinkStar is a new two-way broadband satellite communications system for Internet Protocol connectivity over satellite. LinkStar consists of one or more central stations ¨C the hub ¨C, many remote VSATs (Very Small Aperture satellite communication Terminals), and appropriate management and control subsystems. The remote VSAT ¨C called the Return Channel Satellite Terminal (RCST) ¨C is a small, low cost terminal designed for multimedia broadband connectivity in networks with a large number of sites.

    Because of the low cost of the remote terminal,LinkStar is an ideal solution for large enterprises and service providers (e.g., VPNs and ISPs) that need broadband IP connectivity for multimedia applications over a large geographic area. A single hub can connect up to 10,000 remote terminals, and a multi-hub LinkStar system can integrate as many as 100,000 remotes into a single network.
    This document presents a high level description of the LinkStar product.

Product Overview
    LinkStar is designed to offer high-throughput connectivity between a large number of remote users and one or more hubs, configured in a ¡°star¡± network topology. The connectivity is asymmetric, with a large capacity outbound satellite link from the hub to the remote terminals, and many medium capacity inbound satellite links from the remotes to the hub. This is depicted in Figure 1 below.

The LinkStar system consists of the following:
1. One or more hubs,
2. Return Channel Satellite Terminals (RCST),
3. Network Management System (NMS),
4. Network Control Center (NCC) and Regional NCCs (RNCC), and
5. Space Segment over a bent pipe satellite.

    The transmit HCE consists of a router to interface to the external IP network, a DVB-IP encapsulator to embed the IP data into an MPEG-2 format, a DVB multiplexer, a continuous modulator, and a timing clock .

    The receive HCE consists of a timing and distribution MF-TDMA demodulator unit and multiple MF-TDMA demodulator units for each inbound carrier to be received simultaneously. Each demodulator receives an inbound link from a large number of remote RCSTs. The number of optional demodulators depends on the number of inbound links.Figure 2 depicts the block diagram of the LinkStar hub.

                  Figure 2 ¨C LinkStar Hub Block Diagram

The RCST
    The remote RCST (Return Channel Satellite Terminal) is a smallVSAT consisting of an IDU (indoor unit) and an ODU (outdoor unit). The ODU consists of an antenna (96cm, 1.2m, 1.8m or 2.4m) and an RF power amplifier and low noise receiver.

    The IDU is an integrated unit. The MPEG-2 stream is recovered from the outbound signal by an integrated circuit consisting of a DVB demodulator and demultiplexer. This logic demodulates the outbound signal and the demux recovers the IP packets and time-stamps encapsulated in the MPEG-2 stream, which are then delivered to the external network via a 10/100 Base-T interface.

                   Figure 3 ¨C LinkStar RCST Block Diagram

Management and Control
    LinkStar management and control functions are performed by the NMS (Network Management System), the NCC (Network Control System) and RNCCs (one Regional NCC per outbound carrier).

    The LinkStar network NMS, because of its web-based design, is very user-friendly and flexible. It performs the traditional NMS functions of Configuration, Control, Performance, and Alarm Management, as well as Accounting, and User Administration. It also provides an interface to download software to the RCSTs from the hub.The NMS architecture is illustrated in Figure 4.

                  Figure 4 ¨C LinkStar NMS Architecture

    In turn, the NCC is responsible for managing Regional NCCs (RNCCs), managing the overall allocation of blocks of bandwidth to individual regions, providing an interface to the NMS, SNMP code for configuration and management of the network, and providing an interface for the storage and retrieval of configuration information.

                     Figure 5 ¨C LinkStar NCC Architecture

    A LinkStar network may have one or more RNCCs, one for each outbound carrier. The RNCC is responsible for the management of all RCSTs associated with its region and outbound carrier. RNCC functions include, for example, the allocation of bandwidth within the region, acquisition and dissemination of configuration information, and management of RCST acquisition and synchronization.  

Space Segment
    The space segment for a LinkStar network is of the bent-pipe type, such as Ku-band and C-band transponders of any global or regional satellite system. The satellite capacity may be loopback (such as global or regional coverage) or non-loopback (such as East-West.)

    The LinkStar space segment is made up of one or more broadband outbound links, and many inbound links.

Outbound Link
    The outbound link ¨C from the hub to the remotes ¨C is a multi-megabit data stream that is compliant with the DVB-MPE format. Information is sent from the hub terminal to the large number of remotes over this common link, with the following operating parameters:
¡¤ Transmission Rate: Selectable rate (5 to 42.5 Msps)
¡¤ Format: Continuous (TDM)
¡¤ Modulation/FEC: ETSI-compliant (EN-301210) modulation and FEC
  (forward error correction) formats:
    (a) QPSK with concatenated coding (inner convolutional FEC and
          outer RS), or
    (b) 8-PSK with concatenated coding (inner Pragmatic Trellis
          Coded Modulation (PTCM), outer RS)
¡¤ Transport Stream: MPEG-2 and DVB Multi-Protocol Encapsulation
          (DVB-MPE) format for IP data.

Inbound Link
    In the inbound direction ¨C from the remotes to the hub ¨C the LinkStar network uses multiple links that are shared by associated groups of remote terminals. The inbound link is compliant with a subset of the DVB-RCS standard, with the following operating parameters:
¡¤ Transmission Rate: Selectable rate (156.2, 312.5, 625 or 1250
   Ksym/sec)
¡¤ Format: Demand assigned bursts over multiple TDMA (Time
   Division Multiple Access) carriers
¡¤ Modulation/FEC: Burst QPSK with Rate 2/3 Turbo Code FEC.
¡¤ TCP Acceleration: TCP ¡°spoofing¡± support.

    Other LinkStar important features are indicated below.
¡¤ Network limitation ¨C 5,000+ RCSTs supported per outbound
   carrier, expandable to 100,000  terminals in total.
¡¤ Two-way satellite transmission ¨C 5 to 42.5 Msps outbound carrier,
   and multiple 0.156 to 1.25  Msps inbound carriers, with bandwidth
   automatically allocated based on demand.
¡¤ Many Internet Protocol enhancements:
    (a) Multicast within user groups
    (b) Full routing protocols at remote (RIP1 and RIP2) and at hub
          (BGP4)

This new satellite communications platform combines the inherent flexibility and immediate infrastructure made possible by existing satellite systems operating at C, Ku and Ka frequency bands, with native support for Internet Protocol, flexible network connectivity options, and bandwidth-on-demand.

    With the convergence of applications over IP, many new applications and business opportunities arise every day in geographic regions with insufficient or nonexistent copper and fiber infrastructure. LinkStar now becomes the solution of choice for this type of growing requirement.

High-Throughput Connectivity Over Satellite: LINKSTAR^TM

To meet the region's ever-growing demand for broadband services, LMGT now offers a new two-way broadband satellite communications system for Internet protocol connectivity over satellite - LINKSTARO. LINKSTAR consists of one or more central stations - the hub -, many remote VSATs), and appropriate management and control subsystems. The remote VSAT - called the Return Channel Satellite Terminal (RCST) - is a small, low cost terminal designed for multimedia broadband connectivity in networks with a large number of sites. Because of the low cost of the remote terminal, LINKSTAR is an ideal solution for large enterprises and service providers (e.g., VPNs and ISPs) that need broadband IP connectivity for multimedia applications over a large geographic area. A single hub can connect up to 10,000 remote terminals, and a multi-hub LINKSTAR system can integrate as many as 100,000 remotes into a single network.

LINKSTAR is designed to offer high-throughput connectivity between a large number of remote users and one or more hubs, configured in a "star" network topology. The connectivity is asymmetric, with a large capacity outbound satellite link from the hub to the remote terminals, and many medium capacity inbound satellite links from the remotes to the hub. This is depicted in Figure 1 below. LINKSTAR utilizes an outbound digital video broadcasting (DVB) channel of selectable rate up to 60 Mbps, and a broadband satellite return channel of selectable rate up to 1.150Mbps.

The central station consists of a large antenna (typically 6 meters in diameter), transmit and receive RF equipment, as well as transmit and receive Hub Common Equipment (HCE). The transmit HCE consists of a router to interface to the external IP network, a DVB-IP encapsulator to embed the IP data into an MPEG-2 format, a DVB multiplexer, a continuous modulator, and a timing clock. The receive HCE consists of a timing and distribution MF-TDMA demodulator unit and multiple MF-TDMA demodulator units for each inbound carrier to be received simultaneously. Each demodulator receives an inbound link from a large number of remote RCSTs. The number of optional demodulators depends on the number of inbound links.

The remote RCST (Return Channel Satellite Terminal) is a small VSAT consisting of an IDU (indoor unit) and an ODU (outdoor unit). The ODU consists of an antenna (96cm, 1.2m, 1.8m or 2.4m) and an RF power amplifier and low noise receiver. The IDU is an integrated unit. The MPEG-2 stream is recovered from the outbound signal by an integrated circuit consisting of a DVB demodulator and demultiplexer. This logic demodulates the outbound signal and the demux recovers the IP packets and time-stamps encapsulated in the MPEG-2 stream, which are then delivered to the external network via a 10/100 Base-T interface.

LINKSTAR management and control functions are performed by the NMS (Network Management System), the NCC (Network Control Center) and RNCCs (one Regional NCC per outbound carrier). The LINKSTAR network NMS, because of its web-based design, is very user-friendly and flexible. It performs the traditional NMS functions of Configuration, Control, Performance, and Alarm Management, as well as Accounting, and User Administration. It also provides an interface to download software to the RCSTs from the hub. A LINKSTAR network may have one or more RNCCs, for each outbound carrier. The RNCC is responsible for the management of all RCSTs associated with its region and outbound carrier. RNCC functions include, for example, the allocation of bandwidth within the region, acquisition and dissemination of configuration information, and management of RCST acquisition and synchronization.

The LINKSTAR product is particularly well suited for today's broadband applications. Service providers and multinational corporations can establish extremely economical star networks using one VSAT platform. This is important for a service provider offering virtual private networks (VPNs), or for multinational corporations, since star networks support many applications over the Internet. Typical applications include Internet access, IP corporate infrastructure, digital video broadcast (DVB), distance education, videoconferencing, video streaming, and voice over IP (VoIP). Popular LINKSTAR network examples include Private Corporate Networks, Virtual Private Networks, Internet Service Provider Access, telemedicine, and distance education. While these applications have experienced increased importance in all regions of the world, the Asia-Pacific region stands to be one of the most marketable, given its vast population and geographic area, and ever-growing demand for telecommunications connectivities of all types.

The LINKSTAR product is designed to support large amounts of asymmetric traffic, making it ideal for Internet Service Providers (ISPs). As an ISP increases its coverage beyond the metropolitan areas, low cost broadband IP delivery over satellite becomes increasingly valuable. The hub is installed within easy access to the core of the Internet, and remote terminals are installed at large client locations, or at ISP remote POP (Point of Presence) locations. For example, multinational ISPs serving Europe can extend their services into more remote locations - e.g., the Middle East and Asia. If each RCST depicted in Figure 2 represents a POP connection to local and/or corporate users, then the figure shows an ISP application using one or more high capacity (e.g., 42.5 Msps) carriers designated as outbound, and several smaller carriers (156.2 to 4580 ksps) designated as inbound. The outbound carriers are used to broadcast IP content to all POP locations, each of which serve a large community of dial-in users - or a large corporate user. The inbound carriers are shared among each POP to transport requests to the content-provider. The inbound carriers can also be used for administrative traffic (e-mail, technical support, reports, request for spare equipment, voice, etc.) among the individual POPs in a single satellite hop.

Broadband On-demand Managed Networks: The LINKWAY( Platform and Link One^SM Service.

LMGT recognized the growing market demand for satellite-based broadband, on-demand virtual networks that can provide connectivity for a variety of applications such as voice, data, video, and Internet. To meet this demand, the company developed a platform and satellite system network that employs a multi-frequency TDMA (time division multiple access) architecture which can achieve extremely high efficiency and flexibility in satellite bandwidth management. The LMGT proprietary LINKWAYa unit is a multi-carrier, multi-rate, TDMA VSAT-like platform that works with conventional C or Ku-band satellites. LINKWAY serves as the operating platform for the service, while the rest of the system utilizes existing off the shelf, commercially available earth stations, including low-cost, compact VSAT-like terminals. Unlike traditional VSAT designs, this system offers high data rates (up to 2-4 Mbps/VSAT), full-mesh, single-hop connectivity and high-speed local area network interconnection services. A basic LINKWAY terminal contains a 10 BaseT IP port, and any two of three additional interfaces: ATM, Frame Relay or ISDN. All electronics, including the satellite modem, are housed on a single board in a low profile chassis. The IDU is able to access multiple locations and to support various services to multiple locations.

LMGT's managed network service over satellite is marketed as Link OneSM and provides integrated circuit-switched and packet services over a single satellite hop. Full-mesh connectivity between any user devices connected to the network is available for an essentially unlimited number of users at multiple sites. Link One service can be implemented in a variety of topologies, the most common being star, mesh and hybrid. The Link One network consists of a Network Control Center (NCC) and a number of traffic terminals. One traffic terminal is designated as the Master Reference Terminal (MRT) to provide TDMA timing. The system is controlled dynamically by the full-featured NCC that runs the Network Management System (NMS) Server and performs the bandwidth management function. Figure 3 depicts the utility of the various networking applications and protocols that are feasible in a Link One network.

Link One is particularly suited as a network service solution for entities operating in regions where the nodes are dispersed over wide geographic areas and the existing communications infrastructure is minimal and/or unreliable. For example, a major bank, energy company or international service organization with requirements for a combination of telecommunications services (data, voice, Internet and videoconferencing) that desires the ability for any site to communicate with any other site in its private network would find Link One the ideal platform for delivering this capability. Figure 4 illustrates such a hypothetical network serving locations in the Asia-Pacific region. In this example, six widely-separated nodes are connected in a mesh (hubless) single-hop configuration as a private network. Future expansion (new nodes, bandwidth size or both) can be easily accommodated with minimal impact to the existing network.

Summary.

With its forward-looking broadband-over-satellite products, and its established avenues of regional presence in both satellite services and satellite capacity business investments, Lockheed Martin Global Telecommunications continues to offer the Asia-Pacific market solid solutions to rapidly evolving telecommunications needs. These capabilities combine years of technical expertise with the flexibility needed to adjust to the demands that the future inevitably produces.
