Overview
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC92500/D ΤΜ ATM Cell Processor The ATM Cell Processor (MC92500) is a peripheral device composed of dedicated high performance Ingress and Egress Cell Processors combined with UTOPIA Compliant PHY and Switch Interface ports (see Figure 1).
MC92500 Features • • • • • • • • • • • Full duplex operation at SONET STS-3c, SONET STS-1, DS3 PLCP, or any physical link running up to 155 Mbit/sec Implements ATM Layer functions for broadband ISDN according to ITU recommendations and ATM forum UNI specification Performs internal VPI and VCI address compression (with an option for external compression) for up to 64K VCs Supports up to 16 physical links using dedicated Ingress/Egress MultiPhy control signals Each physical link can be configured as either a UNI or NNI port Supports multicast, multiport address translation Maintains both virtual connection and physical link counters on both Ingress and Egress cell flows for detailed billing and diagnostics Provides a flexible 32 bit external memory port for context management Automated AIS, RDI, CC and Loopback functions with Performance Monitoring Block Test on up to 64 Bidirectional connections Programmable 32 bit microprocessor interface supporting either big- or little-endian bus formats Per-connection leaky-bucket based UPC or NPC design with up to four buckets per connection allows any combination of CLP-aware peak, average, and burst-length policing with programmable tag/drop action per policer Implements separate rate controlled cell insertion and priority based cell extraction queues accessible from all cell flows Supports a programmable number of additional switch overhead parameters allowing adaptation to any switch routing header format Utopia I/F MC92500 ATM Cell Processor ZQ SUFFIX GTBGA CASE 5203 Ordering Information Device MC92500ZQ Package 256 GTBGA • • Ingress PHY I/F (IPHI) MultiPhy Support Ingress Cell Processor (IPU) Ingress Switch I/F (ISWI) ...
