FIELD: alarm signal processing systems for cellular digital communications. SUBSTANCE: method for detecting signal built up in response to channel card change by manager in cellular digital communication system includes check-up of altered information, setting of identification number of channel- interface processor unit and number of iterations per form of base transceiving station, setting of alarm signal code, location of channel component, and location of channel card, detection of alarm signal in particular channel card, its clearing, read-out of base transceiving station form, raising of identification number of channel-interface processor unit, and check-up for execution of operations starting from operation for finding out how many times iterations were made for particular form. EFFECT: enhanced speed due to detecting alarm signal without disconnecting error processor and requesting alarm information. 19 cl, 5 dwg
