| 5.3.1 | Three uses for ISDN

ISDN has many uses in networking. The following sections discuss the following ISDN uses: Remote access Remote nodes Small office/home office (SOHO) connectivity Remote access involves connecting users located at remote locations through dialup connections. The remote location can be a telecommuter's home, a mobile user's hotel room, or a small remote office. The dialup connection can be made via an analog connection using basic telephone service or via ISDN. Connectivity is affected by speed, cost, distance, and availability. Remote access links generally represent the lowest-speed link in the enterprise. Any improvements in speed are desirable. The cost of remote access tends to be relatively low, especially for basic telephone service. ISDN service fees can vary widely, and they often depend on the geographic area, service availability, and billing method. There may be distance limitations, such as being out of a geographic range, with regard to dialup services, especially with ISDN.
