Še eno vprašanje imam.
Mi lahko kdo tole razloži:
It defines the minimum requirements for satisfactory performance of ADSL systems using the Discrete Multi-Tone (DMT) line code. DMT divides the useful bandwidth of the standard two wire copper medium used in the public switched telephone network (PSTN), which is 0 to 1104 kHz, into 256 separate 4.3125 kHz wide freqncy bands called sub-carriers.
To je od standarda ISSUE2.

Definirano je, da so minimalne zahteve za izpopolnjevanje zahtev za ADSL sisteme uporabljati DMT linijsko kodo. DMT razdeli koristno široko pasovno povezavo in tole naprej me zanima?

Hvala
