ConverGate

Access Network Processor

PXF 4271E

Network Processor family designed for aggregation and interworking of ATM or

Ethernet based xDSL traffic on IP-DSLAM line cards.

Infineon ConverGate

Processor with layer 2, layer 3 and layer 4 processing capabilities. It includes a dual

UTOPIA/POSPHY line interface for non-blocking mixed mode ATM cell/ Ethernet

packet support.

The ConverGate

in class power consumption. It includes an AAL5 SAR and integrated Traffic

Management which provides Class of Service (CoS) based queuing, scheduling,

and shaping for de-centralized network services and topologies.

The ConverGate

supported by a comprehensive firmware/ software package. This package provides

a programmable solution which reduces software development time while allowing

flexibility for feature upgrades and extensions.

ConverGate

the reference for DSL Access Nodes. Combined with the xDSL PHY solutions from

Infineon, high performance, low-cost line card system solutions are now reality.
