Title: Communication controller
Inventor: AGEHARI MITSUHIRO
IPC: H04L69/14
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To allow a communication controller which is connected to a plurality of communication lines to control the lines to flexibly deal with the extension of lines. SOLUTION: A line monitor circuit 130 monitors interrupt from lines 151-154 and uses a system generation(SG) comparison processing section 121 to compare the quantity of line speeds of each line causing interrupt when interrupt is received and to set priority of the lines depending on the quantity and a line processing section 133 sequentially process each line according to the priority. Since the controller is configured so that the priority of the line processing is set on each occasion with respect to a line having the interrupt, no effect is placed on the decision of the priority even when number of lines is extended and then the controller copes flexibly with the extension of number of lines.
