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.
