KR970013919A - Low speed data frame inverter - Google Patents

Abstract

The present invention relates to low-speed data frame conversion, and in particular, a low-speed data frame conversion device that enables mutual data connection without an external relay device by enabling conversion of a frame between a DSOB and a CCITT X.50 of a DDS having different multiple systems. It is about.

The present invention is characterized in that the frame extraction means for extracting each multi-frame frame and output as a synchronization signal when the data processed by the multi-way is applied, and generates the DSOB and X.50 frame according to the synchronization signal obtained from the frame extraction means Frame selection means for selecting and outputting a DSOB frame or X.50 frame generated by the frame generating means by a selection signal applied thereto, a frame output from the frame selection means according to a frame synchronizing signal, and the highway Frame addition means for adding data except for a frame applied through and outputting the data as low speed data.
