                                        Digital Network.
                                        • It is a set of CCITT / ITU standards for digital
                                        transmission over ordinary telephone copper wire as well
                                        as over other media.
                                        • ISDN is the integration of both analogue or voice data,
                                        together with digital data over the same network.

Technical Seminar Presentation 2004




                                      • ISDN is an underlying technology, which provides cost-
                                        effective networking through the public telephone
                                        networks.
                                      • ISDN is an important step forward in the adaptation of
                                        the network to handle the increasing global demand for
                                        computer-to computer data communications.
                                      •   ISDN brings us closer to the goal of a ubiquitous multi-
                                          service network, integrating voice, data, video and image.
