Abstract
In a monitor system in a digital communication apparatus including communication processing blocks on transmission paths of digital data, test data inserting units and data monitor units are arranged such that a monitor interval for the monitor operation in a block overlaps with a monitor period for the monitor operation between adjacent blocks in each processing block. As a result, there is no unmonitored interval in each processing block, thereby achieving a complete monitor operation.
