A system for sensing an alarm indicating a failure happening on a trunk in an Asynchronous Transfer Mode (ATM) network. In the system, upon failure to receive an alarm indicating a failure occurrence on the trunk, a base station controller (BSC) determines whether a Loss of Cell Delineation (LCD) alarm happens due to a failure to normally receive data through the trunk. A failure manager manages a failure according to a report on the LCD alarm, received from the BSC. A base station transceiver subsystem (BTS), if it perceives a failure has happened on the trunk, informs the failure manager of the occurrence of the LCD alarm.
