Abstract

Telephone subscriber connections and connection failures are fed into two counters, one for connections, one for faults and are displayed. The two figures are compared and if the percentage of faults becomes greater than a present level an appropriate signal is provided for the exchange. In the figure subscriber lines feed in at (52), operating the indicator and a counting relay (54), fault signals to relay (55) ie when a dialed number fails to obtain a connection. Operation of fault indication can be delayed to avoid generation of alarm signals due to non-representative peaks in the readings.
