Computer Networks and ISDN Systems. pp. 15, No. Asynchronous Transfer Mode can be of two format types which are as follows: UNI Header: which is used within private networks of ATM for communication between ATM endpoints and ATM switches. * ATM have become the essential in gredients in developing high speed networks for local, metropolitan and wide area applications. Currently, to send data you must use a modem to convert from digital signals generated by computers to analog signals that can be transferred on analog phone lines. Unfortunately, the standardization process was too long and regarding to the technology progress in this area, once the standard was finally agreed, it was obsolete.. 3. ISDN can operate over copper based systems and allows the transmission of digital data over the telecommunications networks, typically ordinary copper based systems and providing higher data speeds and better quality than analogue transmission. It includes the Generic Flow Control (GFC) field. It is designed to carry voice, data, images, video, everything you could ever need.
