Evo ti vrlo zanimljiv napis o tome

"ISDN and ADSL: The Technology
A) Frequency Splitting
In most countries ISDN uses a frequency range of 80 kHz. This follows from the 160 kbps (full duplex) bit rate and the 2B1Q line code.
ADSL, like ISDN, specifies the transmission of a bit stream over a twisted copper wire pair. ADSL uses a frequency range of about 1.1 MHz for DMT (discrete multitone).
ITU Recommendation G.992.1 Annex B (ADSL access over ISDN lines) provides for the simultaneous use of ISDN and ADSL."
Ne bih rekao da mozes da sabiras brzine, cini mi se bas komplikovano. Ima na Google puno toga, samo ubaci "ADSL over ISDN"
