ABSTRACT:
An alarm collection apparatus for use in an exchange system has a plurality of local offices, a central maintenance office, a toll switch, and an alarm link. The local offices include an enhanced local office and a conventional local office, the enhanced local office having enhanced features with respect to the number of alarm collection points, a display function thereof, and a man-machine alarms interface. An alarm collection shelf collects alarm information from the conventional local office in the same manner as from the enhanced local office, by converting the data format used for the conventional office to one which corresponds to the data format used for the enhanced office. The alarm collection shelf also collects alarms from a radio base office.
