Nortel 1002 Secure Router SR2101A010E5 用户手册

have excellent latency and jitter charac-
teristics. Collectively, wire-speed
performance and full bandwidth make
the Secure Router 1000 Series platforms
ideal for sites where DS3 connectivity is
cost-prohibitive or unavailable, enabling
organizations to deploy high-speed serv-
ices while conserving expenses.

Scalable bandwidth

Efficient multi-link T1/E1 bonding
allows up to four T1 or four E1 links to
be combined into one logical 6-Mbps or
8-Mbps link, enabling organizations to
add bandwidth without purchasing
more costly DS3 services. Comprehen-
sive Quality of Service (QoS) manage-
ment capabilities deliver services with
low latency, thus allowing voice and
video traffic to share data connections
with no degradation in performance.
The Secure Router 1000 Series scale-on-
demand provisioning architecture enables
network administrators to easily increase
bandwidth and expand functionality
without costly hardware upgrades.

High processing power

Delivering communications at wire speed
with all services enabled requires power.
The Secure Router 1002 and 1004
include integrated Channel Service
Units/Data Service Units (CSU/DSUs),
high-performance 300 MHz processors
and 256 MB DRAM. For enhanced

performance, Nortel provides 16 and 32
MB Flash RAM on the 1002 and 1004
models, respectively. Nortel’s Secure
Router 1001 delivers extremely high
value at an economical price. With one
T1/E1 or serial port, a 266 Mhz processor
and 128 DRAM, the platform provides
exceptionally high performance in a
small form factor. It is ideal for compa-
nies that want to connect to a single-port
T1/E1 or serial WAN service.

Outstanding WAN 
access value

The wide array of advanced features built
into the Secure Router 1000 Series are
key ingredients that provide extraordi-
nary value:

> High-availability features are designed

to ensure no single point of failure.
The Border Gateway Protocol version
4 (BGP-4) enables multi-homing,
allowing organizations to eliminate
potential points of failure; the Virtual
Router Redundancy Protocol (VRRP)
enables redundant router configura-
tions; NxT1/E1 bundling seamlessly
guards against individual circuit failure
and restores bandwidth once a connec-
tion has been repaired.

> Advanced QoS features optimize

bandwidth for voice, video and data
traffic. Organizations benefit from
crystal clear multimedia communica-

tions without impeding data applica-
tions. Comprehensive IP routing
protocols assure high performance,
even with features such as Access
Control List (ACL), NAT and QoS
enabled.

> Multi-link capabilities maximize

bandwidth across multiple circuits to
lower operational costs. 

> Virtual Ethernet technology provides

seamless integration between geo-
graphic locations. Layer 2 tagging,
double tagging and forwarding, and
exclusive Network Address Translation
(NAT) capabilities allow transparent
LAN access across the WAN.

> Integrated IPsec VPN, stateful fire-

> Dual auto-sensing 10/100BASE-T

Fast Ethernet interfaces enable
administrators to quickly and easily
perform remote configuration, provi-
sioning and management.

> Bandwidth and services can be scaled

remotely, simplifying management
and eliminating the need for expensive
truck rolls and hardware upgrades.

> A choice of interfaces enables manage-

ment using a standard Command
Line Interface (CLI) or standards-
based Simple Network Management
Protocol (SNMP) tools.

The Secure Router 1001 and 1001S are suitable for use in

remote offices or in any location needing a direct Internet

connection. Featuring either a single T1/E1 or serial port, the

Secure Router 1001 and 1001S pack a powerful punch in a

feature-packed platform. They can scale from fractional

T1/E1 to wire-speed T1/E1 bandwidth and beyond, even when

forwarding small packets with advanced services enabled.

Optional ISDN BRI backup provides high resiliency.

Secure Router 1002 and 1004 scalable routers provide high-

performance WAN access for enterprise branch offices and

remote sites. These versatile platforms provide a single T1 or

E1 port plus the ability to upgrade to four-port (T1/E1) capacity.

The Secure Router 1002 and 1004 routers each provide unpar-

alleled performance and advanced software functionality in a

compact, highly reliable platform.
