摘要: An automatic communications switching circuit is used to couple a primary terminal, an alternate cluster of secondary terminals and host system enable communication data transfer among the system. The terminal normally handles for when in first state. A lack polling by (which indication inoperativeness terminal) sensed which then starts process. switched second state functions as "primary" terminal.
