Abstract

A tone fault detection system is coupled to a telephonic system, such as an automatic call distributor (ACD) via an ISDN communication link. The ACD includes a multiport switch with a plurality of ports on which tones and messages are provided, and a basic rate line interface device coupled to the multiport switch for communicating with the tone fault detection apparatus. The tone fault detection system includes a telephonic adapter configured to communicate with the ACD and a central processor coupled to the telephonic adapter where the central processor is configured to send and receive data signals and control signals. Also included is an audio detection circuit coupled to the telephonic adapter to receive signals representative of the tones and messages provided by a selected port of the ACD, where the audio detection circuit is configured to measure a power level of the received signal and to provide an indication to the central processor whether the measured power level is within a predetermined range. An alarm circuit coupled to the central processor is configured to indicate to the ACD that the measured power level is not within the predetermined range.
