The article considers the results of clustering i.e. the process of pa
rtitioning objects into classes, in the present case, of protocol V.34
modems, Clustering is carried out according to such parameters as the
rate of transmission and delay of information transmitted to and fro,
Based on the results that are obtained, it is possible to explain tho
se components of modems that, in the present case, partition modems in
to groups and, thereby, determine a corresponding grade of the perform
ance of modems.
