| 摘要 |
The invention relates to a method for detecting errors in a communication system, especially an ATM communication system (Asynchronous Transfer Mode). In the absence of communication signals, monitoring signals are applied at the beginning of at least one monitoring line (7, 8) of said communication system and then extracted at the end of said monitoring line (7, 8). According to said invention, the monitoring line (7, 8) is located within a communication device (1) of said communication system. The absence of signals at the end of the monitoring line (7, 8) corresponds to the presence of an error in the communication device (1). In addition, a communication device (1) has a monitoring line (7, 8) at the beginning of which a power supply (2) is provided and at the end of which an extraction unit (3) is provided. Said extraction unit is designed for detecting and extracting monitoring signals applied by the power supply (2). The invention makes it possible to trigger an alarm-indicating signal (AIS) very quickly after detection of an error in the communication device (1). |
