Infineon Releases New Version of Multi-Service Network Controller for 3G Basestations and Media Gateways

Feb 19, 2002 | Technology Media

Munich, Germany / Cannes, France, 19. February 2002 – Infineon Technologies (FSE/NYSE: IFX), one of the world’s leading providers of Communications Integrated Circuits today announced the release of its next-generation IWORX™ (InterWORking element neXt generation) Asynchronous Transfer Mode (ATM) controller, a multi service engine for line card applications in wireless access networks and media gateways.

With its flexible line interface architecture and throughput of up to 155Mbps the new IWORX now supports all major interface types (E1/T1/J1, E3/T3, and STM-1/OC-3), offering vendors of multi-service systems a much wider flexibility in the usage of 3G wireless and media gateways solutions, saving up on design time, efforts and costs.

The IWORX implements Read Back functionality - a fail-safe mechanism allowing system recovery via read-back of configuration and connection data in the case of power failure or emergency shutdown. The solution is backwards compatible with the previous-generation IWORX.

“3G wireless technology is all about making mobile phones into portable, high performance and reasonably-priced personal computers, therefore it requires a robust infrastructure capable of supporting both voice and high-speed data transmission,” said Mr. Christian Wolff Vice President of Infineon’s Communications Business Group and General Manager of the Access Business Unit. “The next-generation IWORX solution, with its enhanced capabilities will enable mobile infrastructure vendors to scale up their systems and offer integrated voice, Internet access and video services in a cost effective manner,” added Mr. Wolff.

The IWORX solution was designed in collaboration with major players in the 3G infrastructure arena, and fully supports all OAM functionality according to ITU-T I.610 (released 1999) and guarantees enhanced AAL2 traffic management according to ITU-T I.363-2 (released 2000) standards.

First samples of the IWORX PXF 4225 V1.2 will be shipped to selected customers by the end of Q1 2002.

About IWORX™ 3G Wireless Platform

The next-generation IWORX PXF 4225 V1.2 is a flexible communication network controller for 3G mobile infrastructure or multi-service applications. It functions as an interworking element enabling the transport of the ATM traffic over PDH and SDH based networks. The IWORX was designed for line card applications with speeds of up to 155 Mbps, supporting the adaptation of voice, video, and data traffic via AAL 2. Shared location of 2G and 3G mobile networks for easy network migration path is enabled via AAL1 and CES. 4 IMA groups allow flexible bandwidth adjustment of the PDH ports. All necessary ATM service categories (CBR, VBR, UBR) are implemented for full Quality of Service (QoS) support. Being a system on a chip with integrated memory and controlled via high-level command interface (API), the IWORX is the optimized solution in terms of performance, ease of use, space and power economy.
