File Compression There are two ways to reduce the file transfer time through compression. The first method is to allow the modem to use its built-in compression capability. The modem manufacturers have devised a common method that different modems can use to reduce the connection time by reducing the amount data that is transferred without disturbing the content. This method utilizes the fact that most data streams contain redundant data and by reducing the repetitive data, reduce the overall data size. The second method to compress the files that are transferred using the TeleContact is to use a compression program. A compression program achieves the same task as the compression circuitry of the modem (hardware compression) through the use of a special program (software compression). Both aforementioned methods achieve approximately the same amount of compression, however, in some certain cases software compression yields slightly better results. In general, it is recommended to use the software compression method when using the Focus TeleContact since the compression is done prior to the actual transfer of the file and therefore save a small amount of time which otherwise would be spent compressing the file "on-the-fly".
