FEATURES
• Make the most of your network with
wire-speed bidirectional full-duplex
throughput.
• Faster and less expensive than
comparable Cisco routers.
• Aggregate speeds of up to 3.088 Mbps
over T1 or 16.384 over E1.
• Inexpensive midrange standalone
models are available.
• 4- and 8-port rackmount enterprise
models for E1 are also available.
OVERVIEW
Suppose you want to connect various branch offices to a
WAN. Or your enterprise network might need Internet access.
If you’re considering purchasing or currently using a Cisco
router, your network may not be running at its optimum
speed.
Tired of sub-wire-speed performance? Don’t want to spend
the money for costly hardware upgrades? Eliminate sub-wire-
speed performance and on-site hardware upgrades, plus
do away with decreased bandwidth with Series 7000 T1/E1
Routers from Black Box.
These routers provide Internet access for enterprise
networks or WAN access to branch offices, or they work
in service provider sites.
In a typical T1 or E1 network, data is transferred over T1
or E1 cables at speeds of 1.544 or 2.048 Mbps, respectively.
But with Series 7000 Routers, multilink bonding optimizes
bandwidth across multiple circuits. Here’s how it works: The
router combines up to eight lines into one integrated circuit
to provide up to 16.384 Mbps for E1.
And even with all of its enhanced services enabled (details
on page 3), the router still gives you fast throughput and data
transmission—great when you need more bandwidth than
standard T1 or E1 can provide, but aren’t ready to upgrade to
T3 or E3. Purchasing a T1 or E1 router lets you improve WAN
access performance, availability, and scalability without
upgrading or replacing your existing equipment.
An important router feature is its firewall capability.
A firewall guards your network from interfering networks by
using security to control internal and external access to data.
It works closely with the router services to determine whether
to forward traffic onto its destination.
Firewalls are ideal for secure site-to-site communications,
remote access, and parameter security. They provide an
integrated platform for WAN access routing and security,
while maintaining wire-speed performance.
The routers offer more security features, too. Multilevel
passwords keep your network secure, as does the firewall
with SPI (stateful packet inspection).
The router also supports Frame Relay applications.
Layer 2 switching allows for all routing at the core, enables
you to extend Ethernet over WAN, retains VLAN over the
WAN, provides high performance, is protocol independent,
and is easy to configure. Layer 2 also provides Quality of
Service (QoS) based on IP, Port, VLAN ID, and DSCP.
Layer 3 routing enables you to route RIP/OSPF/BG, provides
VRRP, QoS, and radius/TACACS+. Plus, there’s no memory to
add, just a software key to upgrade. It also gives your network
high performance.
