• Manufacturer Part Number: pxb4340e
• Description: Atm Oam Processor Aop
• Manufacturer: Infineon Technologies Corporation

The PXB 4340 E ATM OAM Processor is a member of the Infineon ATM622 chip set. The whole
chip set consists of:
• PXB 4330 E ATM Buffer Manager ABM
• PXB 4340 E ATM OAM Processor AOP
• PXB 4350 E ATM Layer Processor ALP
• PXB 4360 F Content Addressable Memory Element CAME
Main ATM Layer functionality is achieved with only two chips, ALP and ABM. The combination
of these two devices provides elementary ATM functionality like header translation, policing,
OAM support, multicast and traffic management (Fig.1). The functionality is upgradeable to full
OAM support by the AOP (Fig.2) and to arbitrary header translation by CAME (Fig.3).
