High return on investment

Secure Router 1000 Series routers
deliver consistent top-speed perform-
ance at the network edge and provide a
winning combination of standard and
advanced services. These powerful plat-
forms enable organizations to improve

and provision network services, develop
new revenue-generating opportunities,
increase employee productivity, and
build customer loyalty and satisfaction.

Industry-leading performance

In independent tests, the 1004 router was found to:

> Achieve 100% zero-loss throughput in multi-link configurations

of dual and quad-T1 interfaces with VPN, Firewall, QoS and NAT

services enabled

> Provide up to 6 times the throughput of comparable Cisco offer-

ings in tests of 64-byte packets in scenarios tested

> Deliver line-rate bi-directional (full duplex) throughput of 12 Mbps

and 6 Mbps across four and two aggregated multi-link PPP T1

links, respectively

Additional tests have proven that routers, such as the Secure

Router 1001, 1002 and 1004, as well as the new Secure Router

3120, consistently outperform comparable competitive products in

critical data and voice application scenarios. The complete results

of these important tests are available from Nortel.
