ACC Danube

Danube

Small in Size, Big in Features

Danube is a small office access router ideal for meeting the needs of remote sites and branch offices in need of one LAN and one WAN connection.

A true remote bridge/router, Danube offers an extensive suite of features in the smallest, lightest enclosure on the market. Although small in size, Danube delivers full routing support for all the protocols most often found in today's networks. Danube also supports ACC's exclusive Bandwidth Optimization features, which dramatically reduce the lifetime operating costs of your network.

Versatility in Design

The Danube is available in two models: with a single autosensing Ethernet interface that can accommodate either 10BASET or AUI network connections; or with an integrated 8-port 10BASET hub. Both models of Danube use the same WAN interface cards available for ACC's Nile, and can support either RS-232 (V.24), V.35, RS-422, X.21 or ISDN BRI modules. Wide area protocols supported include frame relay, HDLC/LAPB, X.25, PPP and ISDN. These quick-change WAN modules provide maximum configu-ration flexibility so remote sites can be linked via dedicated leased lines, or dial-up links for occasional use applications. With its robust set of Bandwidth Optimization features, the Danube is particularly useful in applications with link speeds at or below 64kbps. And unlike competing remote access products, there is no limitation to the size of the remote Ethernet to which the Danube can connect.

Bandwidth Optimization Features Reduce Network Operating Costs

Danube supports ACC's exclusive Bandwidth Optimization features at no additional charge. Data compression typically reduces the amount of data sent on WAN links by a factor of 4:1. This not only reduces WAN charges, but in some cases eliminates the need to upgrade to faster, more expensive wide area links. Express Queuing provides automatic dynamic allocation of available WAN bandwidth on a per session basis, yielding predictable network response times for all users. Dial on demand allows less expensive switched digital services to be used where leased lines are not cost-effective. Most importantly, these Bandwidth Optimization features can be used together on a variety of wide area services. This results in lower network cost two ways: first, the lowest cost WAN services can be used, and second, no matter what service is used, Danube minimizes the recurring costs.

Downloadable Software

Danube's software is stored in Flash Memory for convenient remote upgrades. Software upgrades can be done either in-band through the network using TFTP, or out-of-band using ZMODEM and the console port. Configuration information can also be uploaded and downloaded through the network. Standard memory configuration includes 2 Mbyte RAM but can be expanded to 8 Mbyte RAM using ACC standard memory modules. This expandable memory allows the Danube to participate as a full router in the largest networks.

Compliance with Standards Ensures Interoperablility

Although ACC would like you to buy all of your routers from us, we understand that real networks often have equipment from multiple vendors. ACC is an active participant in the standards process which is so important in ensuring full standards compliance in all our products. The benefit to you is the highest level of interoperability in a multivendor internetwork.
