摘要：
A method at an alarm monitoring station and security system arrangement for detecting alarm signals originating at security systems on incoming calls carried by a telecommunications line includes, for each call, measuring a noise level on the line in the absence of signals originated by the security systems. Based on the measuring, at least one signal detection threshold above the noise level is set, wherein a level of a signal must exceed the signal detection threshold in order to be detected as a data signal. Alarm data signals in the call are detected using the signal detection threshold.
