The ISDN network can set up a connection in about 3 seconds. This is much quicker
than the PSTN network. This feature alone can result in great timesaving in the long
term.
Why High Speed Analog Modems Can Not Compete With ISDN Digital
Connections?
"The high speed modem can run at 28.8 Kbps and will move data at ISDN-type speeds
when you consider data compression". This assumes a noise-free telephone line and
that the data is easily compressed.
Unfortunately, many image files cannot be
compressed easily, and many telephone lines are far from ideal.
ISDN always
operates at its rated speed.
Also, ISDN cards can also use data compression
technology to multiply its raw data transmission speed.
Telephone monopolies allowing, ISDN will inevitably replace the existing analog
telephone network.
The conversion is being driven by applications such as
telecommuting, home working, remote LAN access, video conferencing and access to
the Internet.
Today, ISDN is available almost everywhere so all users can should be
able to get the benefits from ISDN now.
