Interworking Controller Next Generation
The IWORX (InterWORking element neXt genera-
tion) IC controller is a multi service engine for line
card applications in wireless access networks and
media gateways. It transports ATM traffic over
PDH and SDH based networks.
Supporting speeds of up to 155 Mbit/s, IWORX
enables the adaptation of voice, video and data
traffic via AAL2. Shared location of 2G and 3G
mobile networks for easy network migration path
is facilitated via AAL1 and Circuit Emulated Ser-
vice (CES). The device allows for flexible band-
width adjustment of the PDH ports through 4 IMA
groups and implements all ATM service categories
(CBR, VBR, UBR) for full Quality of Service (QoS)
support.
Being a system on a chip with integrated memory
and controlled via high-level command interface
(API), IWORX is the optimized solution in terms of
performance, ease of use, space & power econ-
omy.
