An Implementation of ESS Software Remote Application System

Software release over the network is the most efficacious way of software update. Software release of electronic switching system, considering its environments, is the typical case that is in need of adopting the method. The media of transferring software and data of TDX-10A electronic switching system are magnetic tapes containing them, so the MT must be delivered between remotely placed office and package generation system. SMART-10A system provides the file tranfer on the data network between TDX-10A and the package generation system and ability of remote application of new software. This paper shows the implementation of file transfer between TDX-10A and computer system connected by data networks, status handling for duplicated system, and monitor process design with IPC on UNIX system.
