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

These are the actions to be performed after reset to prepare the AOP for operation.
• Check reset values of all registers
• Set HW configuration (RAM type, UTOPIA configuration)
• Initialize internal and external RAMs
• Test parity detectors
• Check data path (via adjacent ATM devices)
The following parameters must be known by the microprocessor for the operation of the AOP:
• Number of PHYs
• Edge-of-the-network or intra-network point for each PHY
• Switch Port ID for intra-network Loopback
• Number of supported connections
• Thresholds for PM data collection values
• Use of internal CC function or not.
For a connection setup the following parameters are required:
• Local connection identifier LCI
• VPC or VCC
• If VCC the LCI2 value of the associated VP-entry (VP-pointer)
• VCC endpoint indication (at AAL function)
• PHY number
All further programming is done using the edge-of-the-network or intra-network configuration of
the PHY (for the abbreviations see
• In case of a VCC the upstream part of the AOP is configured as VP-TEP and the downstream
• In case of a VPC without a segment border both up- and downstream parts are configured as
• At OEPs the CC flow generation is enabled (VPC or VCC, segment or end-to-end).
Data Sheet
For this purpose the DMA feature of the chip could be used.
part as VP-OEP. If in addition the PHY is configured as edge of a network the upstream part
is configured as VC-OSP and the downstream part as VC-TSP.
intermediate point (VP-IP). If the PHY is configured as edge of the network the upstream part
is configured as VP-OSP and the downstream part as VP-TSP.
