PROBLEM TO BE SOLVED: To flexibly cope with a signalling processing for the portion of an optional highway number with a simple circuit configuration by processing extraction data from plural highways at high speed, through the means of a time division multiplex mode through the use of a single data processing means. SOLUTION: A signalling processing circuit executes a data processing, such as monitoring, working and converting with respect to specified time division multiplex data on highways. That is, a data extracting means 1 extracts plural kinds of data ai to di from plural input highways CHa to CHd. An ID adding means 2 adds different identifying ID (a/ti to d/ti or the like) to each output data of the means 1. A data processing means 3 data-processes each output data (ai to di) of the means 2 by time division. A data distributing means 4 distributes the respective kinds of output data ai' to di' of the means 3 to corresponding output highways CHa' to CHd' according to the identifying ID (a/ti to d/ti). Thus, multiple kinds of data are efficiently processed with the simple configuration.
