Infineon (Infineon Technologies AG ) : PXB 43202

ATM Switching Preprocessor Downstream

Features include

• Interfaces directly to ATM switching networks built with ASM chips
• Throughput 150 Mbps
• OAM functions according to ITU-T I.610 and Bellcore 1248:

  - Alarms: generation of AIS/RDI cells for all connections (F4 and F5)

  - Continuity check: automatic for all connections

  - Loopback: automatic loop of LB cells

  - Performance monitoring: complete HW support for up to 64 connections

• Double switch plane support for redundant fail save switching systems
• System Control Information Flow via SLIF Datalink supported
• Use external SDRAMs for storage of connection related data
• 16-bit general purpose microprocessor interface
• JTAG boundary scan
• Two high speed serial inputs with individual bit phase adaptation
• Adaption from switch internal SLIF cell format (64 octet) to standard cell format (53 octet):

  - removal of routing header

  - evaluation of synchronization octet, checksums and cell sequence number

  - removal of SLIF empty cells for cell rate decoupling

• Redundant path combining function selectable per connection
• Spatial multicast with individual header translation for each branch
• Logical multicast for an arbitrary number of branches
• Built-in 350 cell deep buffer for data rate adaption
• Support of 1, 3, 4 and 8 output queues in a shared buffer
• Cell counting functions according to Bellcore TA-NWT-1248
• Header translation to any combination of VPI/VCI
• Multiport UTOPIA interface for up to 4 PHYs
