ABSTRACT OF THE DISCLOSURE: The invention relates to a system for and a method of monitoring the activity of a periodically sampled voice-communica- tion line with conversion of each analog line-voltage sample into a binary word including a polarity bit. Successive polarity bits from the sampled line are compared with one another, and the num- ber of changeovers in the binary value of the successive polarity bits within a predetermined test interval substantially longer than a sampling period, are counted. From the number so counted, a numerical value indicative of the character of a signal on the line is derived and compared with a predetermined threshold to ascertain whether the signal has the characteristic of a constituent of a spoken syllable.
