OVERVIEW
1000 Series Nortel Secure Routers are ideal for T1/E1 Internet
access to enterprise networks, for use by ISPs, and for WAN
connections to remote offices— in short, anywhere you need secure,
reliable, end-to-end LAN/ WAN connectivity.
These powerful routers deliver the highest throughput at wire
speed of any comparable router, making them particularly well suited
for secure, converged solutions, including VoIP, private line WAN
connectivity, video, IPsec VPN, data backup, and recovery applications.
One, two, or four ports
The 1001 models are ideal for use in companies that want to
connect branch offices and remote sites to a single-line T1/E1 service,
and for a direct Internet connection. The 1001 models feature a single
T1/E1 port and a 266-MHz processor for high-value at an economical
price.
Choose the 1002 or 1004 models for high-performance WAN
access for enterprise branch offices and remote sites. These routers
provide two or four T1/E1 ports and high-performance 300-MHz
processors.
Each router also includes an integrated CSU/DSU and two
10-/100-Mbps Ethernet ports for fast connections to your LAN.

Scalable
When you need more bandwidth, Secure Routers bridge the gap
by maximizing bandwidth across multiple circuits to lower operational
costs.
1000 Series Secure Routers can scale from fractional T1/E1 to wire-
speed T1/E1 bandwidth. Integrated multilink capabilities enable you to
bond up to four T1/E1 channels into a single logical circuit to create
one connection with over 6 Mbps of bandwidth.
Top performance
A fast-path forwarding engine maintains wire-speed throughput
with low latency. Advanced Layer 2 switching and Layer 3 routing
keep packets moving.
QoS optimizes bandwidth for data, voice, and video traffic so vital
applications get priority and you get flawless multimedia without
interfering with data applications. Comprehensive IP routing protocols
provide high perfor mance even with QoS enabled.
The routers have excellent latency and jitter characteristics. Highavailability features such as BGP-4, VRRP, and NxT1/E1 bundling
maximizes network uptime.

Tight security
Secure routers include the features you need to protect your data
from unauthorized access or corruption.
Virtual Private Networks (VPNs) provide secure communications
for your offices over public infrastructures such as the Internet.
Network Address Translation (NAT) enables the router to “hide”
the IP addresses on your private network from the Internet.
The integral stateful-inspection firewall includes 25-zone support,
policy-based NAT/PAT, and 30+ ALG support including H.322.
and SIP. It also offers policy-based protection against denial of service
attacks.
Technically Speaking
Highly manageable
Secure routers are manageable through the console or AUX port.
Setup is easy with a menu-based GUI tool. For more advanced users,
Command Line Interface (CLI) scripting tools provide even more router
control.
Full SNMP management enables you to easily integrate the routers
into your managed network and manage them using any standard
SNMP management software package.
If you require reliable network connections between remote
sites, T1 or E1 can fit the bill.
Both T1 and E1 are foundations of global communications.
Developed more than 35 years ago and commercially available
since 1983, T1 and E1 go virtually anywhere phone lines go, but
they’re much faster. T1, used primarily in the U.S., sends data up
to 1.544 Mbps; E1, used primarily in Europe, supports speeds to
2.048 Mbps. No matter where you need to connect— North,
South, or Central America, Europe, or the Pacific Rim —T1 and E1
can get your data there fast!
T1 and E1 are versatile, too. Drive a private, point-to-point line;
provide corporate access to the Internet; enable inbound access to
your Web Server— even support a multimedia WAN that extends
halfway around the world! T1 and E1 are typically used for:
Basic T1 service supplies a bandwidth of 1.536 Mbps.
However, many of today’s applications demand much more
bandwidth. Or perhaps you only need a portion of the
1.536 Mbps that T1 supplies. One of T1’s best features is that it
can be scaled up or down to provide just the right amount of
bandwidth for any application.
A T1 channel consists of 24 64-kbps DS0 (Digital Signal [Zero])
subchannels that combine to provide 1.536 Mbps throughput.
Because they enable you to combine T1 lines or to use only part
of a T1, DS0s make T1 a very flexible standard.
If you don’t need 1.536 Mbps, your T1 service provider can
rent you a portion of a T1 line, called Fractional T1. For instance,
you can contract for half a T1 line—768 kbps—and get the use
of DS0s 1–12. The service provider is then free to sell DS0s 13–24
to another customer.
If you require more than 1.536 Mbps, two or more T1 lines
can be combined to provide very-high-speed throughput. The
next step up from T1 is T1C; it offers two T1 lines multiplexed
together for a total throughput of 3.152 on 48 DS0s. Or consider
T2 and get 6.312 Mbps over 96 DS0s by multiplexing four T1 lines
together to form one high-speed connection.
Moving up the scale of high-speed T1 services is T3. T3 is 28
T1 lines multiplexed together for a blazing throughput of 44.736
Mbps, consisting of 672 DS0s, each of which supports 64 kbps.
T4 consists of 4032 64-kbps DS0 subchannels for a whopping
274.176 Mbps of bandwidth—that’s 168 times the size of a single
T1 line!
These various levels of T1 service can by implemented
simultaneously within a large enterprise network. T1’s cousin, E1,
can also have multiple lines merged to provide greater
throughput.

tech support line is closed.
According to a survey by Data Communi cations magazine, 90%
of network managers surveyed say that getting the technical support
they need is extremely important when choosing a vendor. But even
though network managers pay anywhere from 10 to 20% of their
overall purchase price for a basic service and support contract, the
technical support and service they receive falls far short of their
expectations—and certainly isn’t worth what they paid.
At Black Box, we guarantee the best value and the best support.
