FIELD: systems for determining amount of available data transfer resources. ^ SUBSTANCE: for determining amount of resources for data transfer and/or speeds of bits transfer for network connection, with known physical length of cable, measurement of energy spectrum is performed depending on transmission frequency for different types of modems by means of power measuring device, weakening is determined for different physical lengths and thicknesses of cable wires, depending on parameter of cross interference, number of sources and correcting coefficient on bass of energetic spectrum noise level is determined, while by means of gauss transformer module on basis of efficient signal levels and appropriate noise levels amount of data transfer resource is determined for different data transfer modulations and/or modulating codes for predetermined bit transfer speed, then available data transfer resource amount is corrected by means of correcting coefficient, including average deviation of stored amounts of data transfer resources from efficiency amounts of resources of data transfer, and on basis of stored efficient recourses for data transfer with utilization of known physical length of determined network connection available data transfer resource for appropriate network connection is determined. ^ EFFECT: possible determining of amount of available data transfer resources for certain connection. ^ 3 cl, 4 dwg |
