Abstract
PURPOSE: To decrease the information transfer between the channel of the circuit control and the line adaptor by transmitting the interruption signal when the end flag is received and the result of the cyclic redundancy check is correct.
CONSTITUTION: The reception of the end flag by transmission/reception 12 of line adaptor 3 at the data reception time is informed to transmission/reception control circuit 8. In this case, frame check sequence FCS which is stored in 32-bit check register 9-1 and 9-2 is not trnasmitted to channel 1 of the circuit control. The results the CRC operation from the address to FCS are stored in cyclic redundancy check CRC register 11, and circuit 8 reads out the operation result of register 11 with reception of the above information. And in case the operation result is in the fixed value, circuit 8 transmits the interruption signal to channel 1 to indicate that the frame has the normal end and that the CRC operation result is all right.
