Compression Ratio
Data compression will give a 56/64 Kbps link an effective throughput range from 112/128 Kbps when transferring binary
files, to 364/384 Kbps when transferring graphic files. This increased throughput significantly reduces the bandwidth
required across the WAN link to achieve a given performance level and/or allows the use of lower-cost transmission facilities.
