Prosim za vir tega citata.

Ne vem bo drzalo. ADSL omogoca prenosne hitrosti tja do 7 Mbps oziroma
1 Mbps v nasprotni smeri (npr. prenos med centrom K2.neta in pisarno na
Resljevi tece s hitrostjo tja do 450 KB/sec (to je 450 kilobytov v sekundi)).
Pri tej hitrosti je povsem mogoce in realno pricakovati prenos tudi
video prenosa (in celo ne le enega). ADSL je najnovejsa tehnologija,
ISDN pa tehnologija stara 10+ let, ki pa jo v Sloveniji sicer dobivamo
sele zdaj..
