Infineon’s IWORX controller is a multi-service

engine for wireless access network and media

gateway linecards. Designed to transport ATM traffic

over PDH and SDH based networks, IWORX enables

the adaptation of voice, video and data traffic via

AAL2 at speeds up to 155 Mbit/s.

Shared location of 2G and 3G mobile networks for

easy network migration path is facilitated via AAL1

and Circuit Emulation Service (CES). The IWORX

controller also provides flexible PDH port bandwidth

adjustment through four IMA groups, and imple-

ments all ATM service categories (CBR, VBR, UBR)

for full Quality of Service (QoS) support.

Infineon’s IWORX system on a chip with integrated

memory and high-level API command interface is

also easy to use, making it the most optimized

solution in terms of performance, small BOM and

power economy.
