Telephone companies once promoted ISDN as a high-speed access technology. Why has use of ISDN declined?
What will be an ideal response?
When ISDN was first proposed, 128 Kbps seemed much faster than dialup modems. So
telephone companies promoted the technology a lot. But, the newer local loop technologies provide
higher data rates at lower cost, relegating ISDN to a few special cases. Because the speed/quality
offered by ISDN stayed behind some other newer technologies, it’s almost abandoned.
