_How is ISDN line superior to the phone line ?
___
ACCESS TO INTERNET
ISDN subscribers can have access to internet with a higher bandwidth of 64/128 kbps giving significantly improved response time and quality of service compared to internet quality of plain and analog telephone lines. When 64 kbps bandwidth is used for internet, you can still make telephone calls on the other channel , which is a big advantage , since internet connections are likely to occupy the line for very long duration.

ISDN will also support a whole new set of additional facilities called supplementary services.
