We have extensive satellite experience in the United States, Latin America, Europe, the Middle East, and the Far East. We provide advanced earth station equipment or complete satellite turnkey solutions for private networks. In addition, many of the largest commercial networks, such as AT&T, Sprint, MCI WorldCom; national telecom operations in the UK, France, Germany, Canada, Singapore and Brazil; and many government owned networks (PTTs) use our satellite solutions.

Our satellite earth station products, which include both primary and back-up links, provide high capacity backbone circuits to remote parts of the globe. For example, both commercial and government networks use our state-of-the-art satellite TDMA terminals. We have all the engineering and technical support resources to design, install, test, and manage satellite systems and train your personnel in their use and maintenance.

Using our second generation, compact satellite TDMA terminals, installed in over 34 countries around the world, customers can realize a 3:1 cost savings over earlier versions of this technology. Our turnkey satellite systems include system engineering, installation, testing, training, program management, and superior products and subsystems. The TDMA terminal is also available as a standalone product.


TDMA Technology

With time division multiple access (TDMA) technology, you get higher satellite resource use than you can with frequency division multiple access technology, such as INTELSAT IDR. The result? Lower bandwidth cost. For more than a decade, the INTELSAT TDMA system has delivered virtually error free service and outperformed all other INTELSAT transmission and access methods. The incremental growth opportunity of the INTELSAT TDMA system and its flexibility in rerouting traffic translates to lower system operating costs.


TDMA GNS and COMSAT Laboratories jointly developed the model 2760 TDMA terminal. This product delivers efficient and cost effective access to INTELSAT's satellite capacity. INTELSAT markets TDMA satellite service to its signatories operating in the Atlantic, Pacific, and Indian Ocean regions. This product currently serves customers in Europe, Latin America, the Middle East, the Far East, and Africa. This solution, which provides up to 120 Mbps of digital bandwidth, is cost effective for users with traffic requirements for 100 to 200 voice circuits and 10 or more destinations. Customers use this product to interconnect various public switched networks throughout the world and to enhance intersatellite Internet connectivity.

Description
The Model 2760 second generation INTELSAT TDMA complies with the original INTELSAT low cost TDMA traffic terminal system specifications. The terminal is also backward compatible with existing systems. The second-generation terminal uses the most modern state-of-the art digital technology and has a color graphics user interface and compact equipment rack. Expansion space within the compact equipment bay accommodates as many as 24 (48 E1 interfaces) DDIs with redundancy. The TDMA terminal is partitioned into the operator console, IF subsystem, the common TDMA terminal equipment, digital orderwires, DDIs, and the digital redundancy switch.

The operator console provides a modern X-Windows color graphics user interface for all operator display and control. The operator console interfaces to the other subsystems through a highly reliable local area network. The operator console software supports remote operations and provides an upgrade path for emerging network management protocols, such as the Telecommunications Management Network (TMN).

The common TDMA terminal equipment has enhanced features that surpass the basic INTELSAT requirements of IESS-317. These features include burst time plans to respond to daily busy hour requirements automatically. Built-in test capabilities and performance monitoring ensure high reliability of better than 99.99 percent.


Very Small Aperture Terminals (VSAT)

To meet the growing demand of private network owners and cost effectively reach remote parts of the globe, VSATs have become essential in many applications. These products are selected from several suppliers to meet the specific network requirements of our customers. Large commercial users, such as retail outlets, that have many geographically dispersed field locations and need to transmit data frequently, reliably, and cost effectively are one application for this product. New members of the public telecommunications service industry, such as competitive access providers (CAPs), that do not have sufficient traffic at their remote locations to justify a large earth station are another application.

GNS also provides complex communications equipment used in satellite earth stations that provide high capacity backbone circuits to remote parts of the globe. With its full portfolio of network access and radio equipment, GNS can provide virtually every element of your network.
