ATM access
An important trend in telecommunications is the development and fast deployment of broadband networks. The explosive growth in Internet access and inter-LAN connectivity is currently causing bottlenecks in the traditional WAN infrastrudure. The increase in broadband and multimedia applications and the consolidation of voice, data and video over a common communication channel contribute to these bottlenecks.
ATM (Asynchronous Transfer Mode) was chosen by carriers as the multiplexing and switching technique of the future. Migration to ATM networks enables carriers to increase their service versatility and use a common infrastructure for the different interfaces and services.
ATM is a multiservice, high speed, scalable technology that is capable of supporting services with different transfer characteristics. It can simultaneously transport voice, data and video content at very high speeds, with well-defined Quality of Service (QoS) using advanced cell-based switching techniques. As ATM becomes the dominant switching fabric within carrier networks, there is a growing need to develop and deploy cost-effective, QoS-conformant solutions for customer access to public ATM services.
RAD's ATM access solutions were developed to address the need for simplified ATM access starting at the customer premises. They improve and lower the cost of ATM services by offering end-to-end management, Q0S control, traffic management, fault localization, interworking with other services and rate and media conversion.
RAD's ATM access devices also support interworking of other services, such as E1/T1 CES (for voice and TDM connectivity), LAN or Frame Relay, thus providing a single solution for both WAN service concentration over ATM and end-to-end QoS support.
Broadband rate and media converters
Today, many ATM devices, such as ATM switches, routers and multiplexers, support a limited number of interfaces and rates, which makes it difficult for them to interoperate with the wide range of other ATM devices on the market. In addition, the price of high speed ATM ports (such as 622 Mbps) in switches requires a cost-effective conversion solution.
Rate and media converters are the "missing link" for carriers, ATM system integrators and end users. Such devices can offer a conversion between a wide range of media, as well as the capability to adjust different rates using internal buffers. The result is expanded ATM connectivity.
