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

The PXB 4340 AOP is located at the ports of a switch so that each ATM cell passes two
PXB 4340 AOP devices, one at the ingress port and one at the egress port.
The PXB 4340 AOP assumes that all connections are set-up bi-directional with the same Local
Connection Identifier LCI in both directions. In the Infineon Technologies ATM chip set
environment (
contains VPI, VCI and PHY information. The PXB 4340 AOP uses pointers to define a
connection as VPC or VCC (
AOP is not used together with the PXB 4350 ALP it can operate on VPI or VCI identifiers only.
In these cases the OAM functionality is reduced accordingly.
