ConverGate™ -C is the latest addition to Infineon’s

family of ATM and Ethernet communication

convergence processors. ConverGate-C is designed

for xDSL traffic aggregation on IP-DSLAM linecards.

ConverGate-C provides system designers with a

flexible platform for value added services such as video

distribution via Multicast and sets the base for

business class VPNs with its extensive capabilities for

VLAN handling.

With its versatile multiprocessor architecture and

high-speed standard interfaces, ConverGate-C

provides protocol stack support for current and

evolving network protocols. Combined with Infineon's

xDSL PHY solutions, high performance, low-cost

linecard system solutions are now possible.
