Interworking Controller Next Generation

The IWORX-P, a further member of Infineon’s

interworking family, is a flexible communication

network controller. It functions as an interwork-

ing element enabling the transport of the ATM

traffic over PDH based networks. It is found in 3 G

mobile infrastructure as well as in WAN Routers

or multiservice applications. The IWORX-P sup-

ports all features of Infineon’s established IWE-8

but integrates IMA, Microcontroller (e.g. for OAM

functionality) and RAM additionally. It is support-

ing the adaptation of voice and video traffic via

AAL 1 in line card applications with speeds of up

to 16 Mbit/s. Shared location of 2 G and 3 G

mobile networks for easy network migration path

is enabled via AAL1 and CES. Being a system on

a chip with integrated memory and controlled via

high-level command interface (API), the IWORX-P

is the optimized solution in terms of ease of use,

space & power economy.
