IDSL

Updated: 04/26/2017 by Computer Hope

Short for ISDN DSL, IDSL is a technology used to provide DSL over pre-existing ISDN lines. Although IDSL lines usually only carry data, they have the benefit of always being on; thus eliminating the delays are inherent with setting up a call. Also, their transfer rates are slightly higher than ISDN @ 144 versus its 128 Kbps.
