What does ISDN mean?

ISDN means Integrated Services Digital Network

ISDN is digital telephony, which allows multiple connections over one telephone line to be established. Before ASDL became commonplace, ISDN was a way to have high-speed internet and to be reachable by telephone as well. Because it is digital, normal analog devices no longer work, except when you purchase an ISDN power station.
