optimization (compression, prioritiza-

tion, filters), and remote office link

security (firewalling, encryption). Two

types of link routing are supported:

wire-speed LAN-to-LAN (Ethernet,

Fast Ethernet, and/or Token Ring) and

multiple high-speed WAN (T1/FT1/E1).

Provides maximum

investment protection

Beyond answering the needs of most

current remote networks, the futureproof

design of the ARN provides ample

performance headroom for emerging

application requirements. The continu-

ing development of WAN adapter

modules assures an easy, cost-effective

migration path for upgrading to the

newest WAN access technologies.

Features

High-performance processors

and memory modules

The high-performance, highly flexible

base unit of the ARN router contains

a Motorola 33 MHz MC68040 micro-

processor, ensuring high forwarding

and filtering rates across each of its

network interfaces.

Benefits

Delivers extended interface

density and flexibility

With support for up to four LAN and

seven serial interfaces, the ARN pro-

vides an ideal platform for remote sites

combining multiple core legacy devices

(SDLC, BSC, polled Async or X.25)

and LAN-based client/server traffic

(IP and IPX) over Frame Relay, X.25,

X.25 PAD leased line, or dial (analog

or ISDN) links (see Figure 1).

By integrating transmission devices

such as 56K or T1/E1/FT1/FE1 CSU/

DSUs, ISDN BRI, or modems into

the ARN chassis, the number of

multivendor, separately managed

devices and cabling is reduced. This

simplifies remote management and

enhances reliability.

Supports high-performance

networking

The high-performance architecture

of the ARN supports concurrent

execution of compute-intensive appli-

cations including SNA network inte-

gration (Data Link Switching-DLSw),

Advanced Peer-to-Peer Networking

(APPN), SDLC, WAN bandwidth

Optional expansion modules—includ-

ing a choice of Ethernet/Multiserial,

7-serial, or tri-serial—offer additional

serial interfaces. The expansion module

can also hold a LAN interface for

integrating existing low-speed legacy

device traffic (Synchronous Data Link

Control [SDLC], Binary Synchronous

Communications [BSC], polled

Async, or X.25) and LAN-based

client/server traffic over a consolidated

WAN link to the corporate backbone.

The ARN employs Motorola

MC68040 and MC68360 micro-

processors to handle the demands of

compute-intensive internetwork

applications. This includes multiproto-

col routing, SNA integration, traffic

management, and high-speed WAN

communication.

Seamless integration with the enterprise

internetwork is ensured through Nortel

Networks Optivity* network manage-

ment application support for compre-

hensive node configuration, monitor-

ing, and control. Optional embedded

Ethernet Remote Monitoring (RMON)

probes—Data Collection Modules

(DCMs)—provide visibility into

network activity at remote sites

where there is typically

no dedicated support staff.

Software RMON support

is available for the 10-Mbps

and 100-Mbps systems.

The ARN is a critical part of

the product family. Combined

with the 10BaseT stackable

hubs, 100BaseT hubs,

Ethernet/Fast Ethernet

switches, and remote access

devices, the ARN delivers

a robust, scalable solution

for providing remote

office connectivity to

the enterprise network.
