Integrated Services Digital Network is a telephone system network. It is a wide area network becoming widely available. Prior to the ISDN, the phone system was viewed as a way to transport voice, with some special services available for data. Computer systems consist of large numbers of individual equipment and software components, the failure of any one of which may bring down the system. Often these components are concentrated in one or a few places increasing the vulnerability to accidents. The classical remedy for system failure was to revert to the manual processes that the computer system superseded. In the majority of cases
