Abstract

PURPOSE:To make use of a system for a packet switchboard, etc., by making it possible to transmit one data frame during the transmission of another data frame, by giving a difference between starting codes of priority and unpriority data frames. CONSTITUTION:Flag sequence of priority frame (a) is denoted by F, and that of unpriority frame (b) is by (f). Transmission control function part 6, consisting of control part 1 for the function, transmission-reception data buffer part 2, and character arithmetic part 3, is connected to both interface line 4 to another processing part and transmission circuit 5 for frames. Further, arithmetic part 3 allows generation detection part 30 for a specific pattern to detect the generation of the F pattern, (f) pattern, disclaimer pattern, and call end pattern and also includes arithmetic check part 32 for frame check sequence FCS and ''0'' insertion-removal part 31 which inserts ''0'' every 5th ''1'' in case of transparent transmission, namely, data of continuation of ''1'' and removes ''1'' at the reception time.
