Access Stack Node Router (ASN)
The Nortel Networks* Access Stack Node
(ASN) is an award-winning, stackable
router that offers flexible, cost-effective,
growth-oriented solutions to meet the
connectivity needs of headquarters and
remote offices. The ASN is the only
router that provides seamless integration of multiple stacked units managed
as a single router. The ASN router
provides an aggregate system performance
of up to 50,000 packets per second (pps)
per ASN unit using Fast and Packet
Cache (FPC). A fully configured ASN
stack supports up to 48 ports and an
aggregate forwarding performance of
up to 200,000 pps. The ASN router’s
Stack Packet Exchange (SPEX-HS)
provides a processor interconnect of up
to 512 megabits per second (Mbps)
between ASN units, and allows for the
hot swap of any ASN router in a stack.

Five great reasons to
choose Nortel Networks
Simplifies installation
and management
• Nortel Networks Optivity* family of
network management tools provides
a comprehensive set of network
management capabilities—down to
the virtual circuit level—for HP-UX,
IBM AIX, and Sun Solaris platforms.
• Bay Command Console (BCC)
allows for local or remote configuration and maintenance.

• SPEX-HS system enables ASN
stacks to grow and be managed as a
single router.

• Hardware and software fault
resiliency isolate failures to deliver
increased availability.

• EZ Install and EZ Update reduce
installation time and simplify ASN
router management.

• Alternate path routing and dial
backup maintain WAN connectivity.

Optimizes network performance
• Data compression, bandwidth reservation, and bandwidth-on-demand
reduce costs by maximizing efficiency
of wide area network (WAN) bandwidth usage.
• Bandwidth management and QoS
services, including DiffServ, allow
dynamic control of network traffic
to provide high quality and level of
service, based on application, user,
or other criteria.
• Directory and policy services enable
network control through centralized
or distributed databases of usage rules.
• Fast Packet Cache (FPC) further
increases forwarding performance.
Enhances network availability
• Interface and router redundancy
protect against failures that cause
network outages.
• Hot-swap capabilities eliminate the
need to schedule downtime to
service or reconfigure an ASN
router, or replace a unit in a stack.

• Partial boot capability enables the
ASN router to be started in the
event of failed hardware and/or
configuration errors.
• Redundant power provides backup.
Extends network connectivity
• Support for up to 48 network interfaces fulfills the expansion needs of
network centers and regional offices.
• Comprehensive protocol support from
Nortel Networks Routing Services
(BayRS) for LAN protocols (IP, IPX,
AppleTalk, VINES, DECnet, OSI,
and XNS); Bridging (Transparent,
Source Route, and Translation);
WAN services (PPP, Frame Relay,
SMDS, X.25, ISDN BRI, ISDN
PRI, and ATM DXI), and IBM
integration (DLSw, APPN, Bisynch
[Sync] over TCP/IP) enables the ASN
to adapt to almost any environment.
• LAN net modules offer flexible
support for 10Base-T, 100Base-T,
FDDI, and Token Ring.

• WAN net modules meet connectivity
requirements for ISDN PRI and
BRI, Channelized T1/E1, Synch/
Asynch serial, and HSSI.
• Expanded IP support through
scalable IPv4, OSPF, BGP-4, NAT,
IP Multicast, and IPv6 increases the
ASN router’s functionality.
Heightens network security
• RADIUS authentication support
allows only authorized ISDN
dial-in links.
• WAN encryption, DES 40/56
provides the ability to protect sensitive traffic across dedicated links.
• IPSec supports industry-standard
encryption and authentication for
intranet and extranet. IPSec is
compatible with Nortel Networks
Contivity* VPN switches.

Hot buttons
• Flexible design—Stackable,
“future-proof ” design allows you
to add units as your network grows.
• Enhances network performance—
High-performance architecture
supports up to 48 interfaces and
forwards an aggregate of up to
200,000 pps.
• High network availability—High
resiliency and redundancy enhance
network availability.
• Low cost of ownership—Simple
installation and management reduces
cost of ownership.
• Reduced WAN costs—WAN optimization features such as hardware
and software-based data compression,
priority queuing, Uniform Traffic
Filters, and bandwidth aggregation
significantly reduce WAN costs.
• Delivers enhanced IP services—
Nortel Networks leads the industry
with advanced IP services such as
Bandwidth Management, Policy
Management, and Internetworking
Services to deliver highly optimized
IP networks. (BayRS provides
advanced security through IPSec
interoperability with Contivity, bidirectional NAT support, IPSec/
NAT forwarding filters, and RADIUS
enhancements for SecureID.)

• Layer 3 solutions—The ASN router
provides fully integrated Virtual LAN
(VLAN) support with all Nortel
Networks switching products, delivering multiprotocol migration and
WAN remote office concentration.
In addition, Nortel Networks provides
Differentiated Services (DiffServ)
and Virtual Router Redundancy
Protocol (VRRP) support.
