<ul><li> 1. Quality Voice Bandwidth Efficient VoIP Solutions Netrix VoIP Solutions VoIP High Quality Voice Ideal Solution for Bandwidth Challenged Environments Award-winning voice clarity Design and field-proven for harsh environments Scalable and Flexible H.323 &amp; SIP compliant Voice over IP (VoIP) offers organizations substantial benefits, including reducing the cost of business communication. For end users, the ability to merge all voice and data onto a simplified system has powerful appeal. For service providers, the Combined Voice and ability to provision and maintain a single network for both voice and data provides a significant operational advantage. Data over any infrastructure Unfortunately, there can be a shortcoming with VoIP, the amount of bandwidth required to provide the desired voice quality can be higher than anticipated. Organizations are often forced to choose between sacrificing voice quality in Standards compliance order to realize the cost savings, or forego the cost savings in order to maintain ensures superior quality. interoperability Netrix Network Exchange Nx2200 gateway products from NSGDatacom provide the solution to this dilemma. The product family was developed by the inventors of packetized compressed voice and leaders in quality, bandwidth-efficient voice solutions. The Nx2200 product line utilizes both standard and patented voice Soft configurable voice compression technologies (12:1 voice compression) to deliver high quality voice ports over a variety of fixed-line, wireless, and satellite links at efficient data rates. Toll quality voice is achieved while realizing bandwidth efficiency by use of sophisticated queue buffer, jitter buffer and echo cancellation mechanisms built WAN support via Frame into the product. Additionally, the Netrix products are field-proven to operate in harsh environments. Relay over high-speed serial interface NSGDatacom products are deployed worldwide in corporate, financial, government, military, carrier, satellite, and cellular networks. The following applications are examples of Netrix solutions that were chosen by customers Low power budget wanting to take advantage of the benefits of VoIP in environments where high quality voice was crucial and bandwidth was at a premium.

Quality Voice Bandwidth Efficient VoIP Solutions Quality with Bandwidth Efficiency At NSGDatacom, we understand that the drivers for implementing VoIP solutions are to take advantage of bandwidth cost savings and to realize the operational benefits emanating from the consolidation of voice and data networks. Our gateway products, renowned leaders in quality, bandwidth-efficient voice solutions, allow our customers to realize these benefits without having to sacrifice voice quality. Our superior, proven technology allows our products to use significantly less bandwidth than our competitors for VoIP applications. When using the Netrix 8Kbps toll quality compressed voice, only 40Kbps of bandwidth is needed for four voice calls. Even less bandwidth can be provisioned when the silence suppression technology is also utilized. Standards-based VoIP requires a centralized call router, with every call having to be established by this call router. If the path to the call router fails so do all the voice calls, which has serious implications for both reliability and bandw...</li></ul>
