Transmission Capacity of Local Copper Cables
Local network planners encounter with problem how to evaluate and predict the transmission speed of ADSL systems operating at copper cables where another xDSL systems operate as well. Model for such analysis is developed and presented. Model is based on measurements of real values of crosstalks among the cable pairs, spectra of transmitted signals and achievable transmission speed of ADSL systems. Model could be extended for the ADSL 2+ as well. Ill. 5, bibl. 4 (In English; summaries in English, Russian and Lithuanian).
