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

The PXB 4340 AOP contains 128 PM processors which may be used to generate an FM flow or
to terminate an FM flow. Terminating an FM flow means analyzing and looping of the FM cells
as BR cells. During one cell cycle
level.
It may happen that a user cell belongs to a VCC for which F5 segment PM is done. E.g. in the
example of
VPC TEP. In this case the arrival of a VCC user cell triggers two PM processors in the upstream
part of the PXB 4340 AOP.
In case of F4 and F5 segments e.g. the downstream part of a PXB 4340 AOP could be
configured as VPC OSP and VCC OSP (
triggers two PM processors simultaneously, but might also complete two PM blocks. Then two
FM cells have to be generated simultaneously. In this case the PXB 4340 AOP first inserts the
VP-FM cell and then the VC-FM cell.
