摘要:
A communication system uses a two-wire circuit and includes a master terminal and a backup terminal, and a main file and a backup file along with associated link control devices coupled to a plurality of satellite terminals. Each link control device functions both as a monitor and as a communication controller with priority between the link control devices for each of the files and terminals to maintain operation of the system.
