FEATURES

Point form summary of features.

• Monolithic single chip device which handles bi-directional ATM Layer functions including

VPI/VCI address translation, cell appending (ingress only), cell rate policing (ingress only),

per-connection counting and I.610 compliant OAM requirements for 65536 VCs (virtual

connections).

• Instantaneous bi-directional transfer rate of 800 Mbit/s supports a bi-directional cell transfer

rate of 1.42x106 cells/s (one STS-12c or four STS-3c).

• The Ingress input interface supports an 8 or 16 bit SCI-PHY interface using direct addressing

for up to 4 PHY devices (compatible with Utopia Level 1 cell-level handshaking) and Multi-PHY

addressing for up to 32 PHY devices (Utopia Level 2 compatible).

• The Ingress output interface supports an 8 or 16 bit SCI-PHY (52 – 64 byte extended ATM cell

with prepend/postpend) interface (compatible with Utopia Level 1 cell-level handshaking) to a

switch fabric.

• The Egress input interface supports an 8 or 16 bit extended cell format SCI-PHY interface

using direct addressing for up to 4 PHY devices (compatible with Utopia Level 1 cell-level

handshaking) and Multi-PHY addressing for up to 32 PHY devices (Utopia Level 2

compatible).

• The Egress output interface supports an 8 or 16 bit extended cell format SCI-PHY interface

using direct addressing for up to 4 PHY devices (compatible with Utopia Level 1 cell-level

handshaking) and Multi-PHY addressing for up to 32 PHY devices (Utopia Level 2

compatible).

• Compatible with a wide range of switching fabrics and traffic management architectures

including per-VC or per-PHY queuing.

• Highly flexible OAM-type cell and connection identification which can use arbitrary

PHYID/VPI/VCI values and/or cell appended bytes for connection identification (N.B. this is an

ingress function only). A direct lookup function is provided in the egress direction. The direct

lookup can use an arbitrary header or prepend/postpend location.

• Ingress functionality includes a highly flexible search engine that covers the entire

PHYID/VPI/VCI address range, programmable dual leaky bucket UPC/NPC, per-connection

CLP0 and CLP1 cell counts (programmable), OAM-PM termination, generation and

monitoring, and OAM-FM termination, generation and alarm generation (monitoring).
