The

Automatic Update Service (AUS)

your hardware modules are up-to-date with the latest code functions and improvements. Available on a 3-year subscription basis, AUS subscriptions cover all your feature modules with independently upgradable code components. With AUS subscriptions, you automatically receive the newest versions of code when they are made available.

To subscribe to AUS from Europe, the Middle East or Africa, fill out the form that comes in the ATM Workgroup Switch package and return it to the IBM address indicated. ATM Workgroup Switch software updates will then be sent to you at the address you specify. If you reside in the U.S.A., it is not necessary to fill out the form in order to receive ATM Workgroup Switch software updates.

subscription is a simple and cost-effective way of ensuring that

Improved Decision Making

With the 3-year subscription, it is easy to predict the annual cost of upgrading your network with the latest code functions. Also, since you always have the latest version of management modules, fewer planning considerations are required when ordering new media and interconnect modules.

Asset Protection

The automatic distribution of the latest code versions ensures that your hardware is always up-to-date with the latest set of functions, thereby expanding the life of your network, and reducing compatibility problems.

Connectivity Improvements

With the latest version of code in place, your management and interconnect modules are automatically upgraded with the latest performance and configuration improvements, as well as new bridging or routing features.

Network Operations Productivity

The AUS subscription ensures that the ATM Workgroup Switch or modules (of a given type) in your network are kept at the same level of code, therefore making network operations simpler and more consistent. Also, with the latest version of the management module installed, the network manager can perform configuration and problem management for all the newly announced hub components and modules without restrictions.
