Abstract

A private branch exchange system, comprising an exchanger operable to connect a plurality of extension lines and at least one office line and having various functions concerning exchange between the extension lines or between the extension lines and the office line, and a computer for carrying out part of the functions of the exchanger. The computer comprises means for monitoring abnormality in said computer, and means for informing the exchanger of abnormality monitor results obtained by the abnormality monitoring means. The exchanger comprises means for receiving the abnormality monitor results from the computer, means for discriminating abnormality on the basis of the abnormality monitor results received by the abnormality receiving means, and abnormality response means for optionally disconnecting the computer from the exchanger on the basis of discrimination results of the abnormality discriminating means.
