Abstract
A method of detecting a pulse density violation in the T1 transmission of digital signals, which includes counting bits in sets of 'k' successively in n serial stages generating an empty-out signal on detection of an 'empty' set of 'k' bits, and generating a pulse density violation on detecting a second set of 'k' zero bits in the 'n' stages of bits at a time when the empty-out signal is present.
