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.
