Possibility of multimedia services providing by ADSL system over long local loop

This paper analyses possibility of ADSL signal over long symmetrical copper-based twisted pair (about 7000 meters) establish. Got rate, its stability and possibility of its increase by effect on symmetrical copper-based pair primary parameters is analysed. Establishment of stable rate ADSL signal of enough value can be used for multimedia services providing through such ADSL system. Pair from 7100 meters long cable, with 0.4 millimetres conductor diameter polyethylene insulation and aluminium sheath is measured.
