Welcome to ISDN

Integrated Services Digital Network (ISDN) technology provides a fast, accurate and reliable
means of sending and receiving voice, data, images, text, and other information through the
telecom network.
ISDN uses existing analog telephone wires and multiplex it into separate digital channels which
increases bandwidth.
ISDN uses a single transport to carry multiple information types. What once required separate
networks for voice, data, images, or video conferencing is now combined onto one common
high-speed transport.
Refer to the following information:
• "Types of ISDN service" on page 536
• "ISDN layers" on page 536
• "ISDN bearer capability" on page 537
