With continued globalization, may corporations have workgroups dispersed around the world. To support workgroup prodictivity and communications companies are considering cost effective and less expansive network solutions that combines voice, wireless, data and video. These businesses expect the services they select and implement to have the high quality of the telephone and other services they now use, and they expect them to boost productivity and help reduce overall communication costs. To access the desired network services requires connections from wireless, wireline networks, and the Internet to Public Switched Telephone Network (PSTN) with flexible, robust, scalable and cost-effective media gateway. These gateways must reduce cost of communication of the dispersed workgroups and form the foundation for media services.
Media gateways bridge multiple technologies.
Today all communication can take place through a computer. Widely accessible broadband and Internet Protocol (IP) enable voice, data and video. Media gateways provide conversation and switching voice media between a network and its access point. Digital Subscriber Line (DSL) or cable modem a media gateway converts, compress and and packetizes voice data for transfer back and forth across the Internet backbone for wireline or wireless phones. Media gateways fit between the PSTN and wireless or IP-bbased networks.
Why modular media gateways for VoIP?
Several market demands are pushing companies to converge all of their media services using media gateways,with VoIP.Companies are expecting this architecture to:
- Lower initial costs. Capital investment is less because hardware can be usedfor multiple functions.
- Lower development costs.Open system hardware and software standards with welldefined application mean lower costs, and Application Programmable Interfaces (AAPIs) accelerate development.
- Handle multiple media types. Companies want VoIP solutions today, but need to select solutions that will also handle video in the near future.
- Lower the costs of deployment and maintenance. Standardized, modular systems reduce training costs and maintenance while also improving uptime.
- Enable faster time-tto-mmarket. Early market entry hits the window ofopportunity and maximizes revenue.
Investing in the future
In the past networks applications dedicate separate, often proprietary and costly costly networks for each application. Media gateway's horizontal organization offers the advantage of a common architecture for all applications Today media gateways can ensure the interworking of transactions between different technologies by enabling services for media-based application involving voice, data, faxes and video.
