FEATURES

• Monolithic single chip device which handles ATM switch Ingress VPI/VCI

address translation, cell appending, cell rate policing, counting, and OAM

requirements for 65,536 VCs (virtual circuits)

• Instantaneous transfer rate of 200 Mbit/s supports a cell transfer rate of

0.355x106 cells/s (one STS-3c).

• Concentrates the traffic from several PHY interfaces into one switch port.

• 8 bit PHY interface using direct addressing for up to 4 PHYs (compatible with

Utopia Level 1 cell-level handshake) and Multi-PHY addressing for up to 32

PHYs (Utopia Level 2 compatible).

• 8 bit extended cell format SCI-PHY (52 - 64 byte extended ATM cell with

prepend/postpend) interface at output to switch fabric.

• Compatible with wide range of switching fabrics and traffic management

architectures including per VC or per PHY queuing.

• Provides identification/tagging of RM cells to support adjunct processing

applications such as Virtual Source/Virtual Destination ABR service.

• Supports logical multicast.

• Flexible CAM-type cell identification which can use arbitrary VPI/VCI values

and/or cell appended bytes for identification.

• Discards on command all low priority (high CLP bit) cells to relieve switch

congestion.

• Can discard or tag the remainder of an AAL5 packet if a single cell in that

packet is discarded or tagged due to policing.

• Includes a 16-bit FIFO buffered microprocessor bus interface for cell

extraction and insertion (including OAM), VC table access, control and status

monitoring, and configuration of the device.

• Supports DMA access for cell extraction and insertion.
