Line 4:

'''Rate-Adaptive Digital Subscriber Line''' ('''RADSL''') is a variation of [[Asymmetric Digital Subscriber Line]] (ADSL) technology. In RADSL the [[DSL modem]] adjusts the [[upstream_(networking)|upstream]] [[Bandwidth (signal processing)|bandwidth]] to create a wider frequency band for the downstream traffic. Using this technique the line is more tolerant of errors caused by [[Noise (physics)|noise]] and signal loss.

As the frequency is adjusted, the upstream bandwidth may be markedly decreased if there is a large amount of line noise or signal degradation - this may reduce the upstreamupstreambvchgvchgvchgchghghgcchchcgcgcnrfxtxytrfdrdytrdctr [[bit rate]] to as little as 64 kbit/s - the same speed as a single [[ISDN]] [[B channel]].
