Some bridges allow address information to be manually configured into the bridge, provided the automatic learning facility is turned off, although this will not normally prove necessary unless specific traffic filtering is required.
You can also configure a number of other features to improve the performance and operation of the AccessBuilder 500. These include sophisticated frame filtering techniques so that only certain types of frame, or those associated with particular work groups, are passed between specific segments.

The AccessBuilder 500 is able to send frames between LANs that may be separated by considerable physical distances. It achieves this by making use of digital ISDN links. ISDN services are usually operated by telephone companies (PTTs) or other service providers.
