ACC Danube
Part Number: NB-90-2267-01


Danube Standard Router Featuring TCP/IP, IPX, Appletalk, DECnet, XNS and Bridging Support. Includes Bandwidth Optimization Feature Set and 2.0MB Flash Memory.



The ACC Danube is a remote access bridge/router ideal for meeting the needs of remote sites and small branch offices.

A true remote access bridge/router, Danube offers an extensive suite of features in a small, lightweight enclosure. Ideal for small branch offices in need of one WAN connection to a regional or corporate location or for those wanting connectivity to the Internet "Superhighway," 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 10Base-T or AUI network connections or with an integrated 8-port 10Base-T hub. Both models of Danube use the same WAN interface cards 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, ISDN, X.25, PPP and HDLC/LAPB. These "quick-change" WAN modules provide maximum configuration flexibility so remote sites can be linked via dedicated leased lines or switched digital services, as well as utilize dial-up access 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 64Kbs. 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. These features include data compression, Express Queuing and advanced dialing techniques. Data compression 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. ACC's exclusive 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 in two ways: 1) the lowest cost WAN services can be used and 2) 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. Redundant Flash image capability for both application and configuration files ensures robust network operation and resiliency. Configuration information can also be uploaded and downloaded through the network. Standard memory configuration includes 2.0MB RAM but can be expanded to 8.0MB RAM using ACC standard memory modules. This expandable memory allows the Danube to participate as a full router in the largest networks.
