Efficient Networks Business Class Router and Gateway Details
Digital subscriber line (DSL) is an ideal business class Internet access tool: it’s fast, reliable, and economical. DSL
provides transmission speeds equal to or better than many traditional high-speed options for business, at a fraction of
the cost. If multiple computers are to be supported, a business class DSL router or gateway easily provides access
for all networked systems, or forms the basis of a new internal network if one is not already in place.
To really take advantage of DSL’s benefits, however, it’s important to select a business class device with the right
capabilities and performance. Efficient Networks business class products are engineered to be the perfect DSL
delivery solution for a variety of customer applications: they excel at providing all networked users with lightning-
fast Internet access and simultaneous, always-on access to e-mail, the Web, and all other Internet-related services.
Efficient Networks business class products deliver because they’re versatile. The various models support each of the
commonly available DSL types—ADSL, SDSL, IDSL, and SHDSL. All associated models have the same software
and feature set, but each uses hardware and software fine tuned for a specific type of DSL service.
Efficient Networks business class products are also secure. They include advanced routing capabilities, like IP/IPX
routing, bridging, network address translation (NAT and NAPT), dynamic host configuration protocol (DHCP) for
auto-configuration of networked systems, a built-in IP filtering firewall, VRRP, dial backup, and optional secure
Virtual Private Network (VPN) capability.
Very important for growing organizations, Efficient Networks routers and gateways are scalable, too. As the
network grows, Efficient Networks business class products scale to fit new needs—easily supporting new or
multiple network configurations and providing simultaneous Internet access for hundreds of users.
Efficient Networks 5800 Business Class Router
The Efficient Networks 5800 Business Class router series includes three products: the 5851, 5861, and 5871. All
three are virtually identical in terms of features and benefits. They differ only in the type of DSL service type with
which they’re designed to work: Symmetric DSL (SDSL), Asymmetric DSL (ADSL), and Integrated Services
Digital Network DSL (IDSL).
