Access Stack Node Router
router supports major network bridging protocols, wide area services, standards. fault-resilient system software ensures high network availability. interfaces meet connectivity needs remote campus offices, data compression coprocessor provides compression over interfaces, reducing number circuits required meet network bandwidth needs. satisfies connectivity, performance, availability requirements ranging from workgroup remote site access high performance, highly available network centers.
Features Benefits
Ensures Network Availability Enhances Network Performance Extends Network Connectivity Simplifies Network Administration Provides Cost Ownership
Nortel Networks Access Stack Node (ASN*) stackable router architecture providing cost-effective solutions enterprise network centers. provides seamless integration multiple units stacked together managed single router. Adding interfaces beyond unit's capacity does require replacing routers adding complexity network. stack supports 200,000 packets second with network interfaces.

BENEFITS
Ensures Network Availability
Extends Network Connectivity
Flexible Network Environments
operates BayRS* suite extensive, proven multiprotocol services. maintains high availability through hardware software fault isolation recovery, online dynamic reconfiguration. ASN's hot-swap capability supports replacement individual units within stack. stack configurations also support multiple PCMCIA Flash memory cards redundant nonvolatile storage system software. Flash partitioning provides file system redundancy single configurations. Redundant interfaces router features, along with redundant power supplies, ensure continued network operation.
Enhances Network Performance
provides cost-effective, entrylevel solution network centers. ASN's unique "stackable" architecture supports four ASNs (with network interfaces unit) which interconnect many networks.
Simplifies Network Administration
uses highly scalable architecture, which provides cost-effective, growth-oriented solutions enterprise network centers (see Figure Typical applications configurations include: Remote Office
stack size managed single device network. stack expands, workload network operations staff does increase support router. requires only software image configuration file.
Provides Cost Ownership
Large offices consisting several LANs, SNA/SDLC devices, highspeed LANs Network Centers with application servers services supporting extended enterprise network.
provides high system performance 50,000 unit. four-unit stack supports forwarding performance 200,000 pps, with megabits second (Mbps) bandwidth using dual network modules between ASNs. User-configurable DRAM fast packet cache options optimize system memory requirements.
reduces equipment costs with features such high port densities integrated MCT1, CSUs/DSUs. also supports large numbers virtual circuits single node. Data compression further reduces number required circuits. ASNs allow multiple individual routers interconnected create single multiprocessor router. This inherent scalability allows future needs addressed.

HARDWARE FEATURES
High-Performance Processor
ASN's processor module maintains high filtering forwarding rates. ASN's megabytes DRAM configurable support buffers which prevent traffic overflow network delays. ASN's optional Fast Packet Cache increases forwarding performance. supports standard Type Flash memory card nonvolatile storage ASN's system software, configuration file, event log. Flash locally divided into partitions equal size, additional cards used store backup copies software image configuration file.
ASN's processor module four interface module (net module) positions cost-effective network connectivity.
Serial Interfaces
Stack Packet Exchange Hot-Swap (SPEX-HS)
provides network connectivity selection modules (see Table
Hardware-Based Data Compression Coprocessor Module
data compression coprocessor module offloads compression decompression tasks from main CPU. This module supports ISDN, PPP, Frame Relay links, interoperable with hardware software compression operating other Nortel Networks routers (see Table
SPEX-HS module cable combine interconnect base units together into single router allow individual unit stack removed from added stack, without affecting operation remaining units stack. cable four connectors forms interconnecting from four units. Using extra cable provides redundancy higher bandwidth. SPEX-HS module operates interconnect Mbps. When SPEX-HS cables used, effective speed SPEX-HS Mbps.
Packaging Power Options
available single power supply model with power supply redundant power supply models supporting power supplies.
