Abstract
In a remote monitoring system, a supervision terminal (37) monitors the status of the communication link (32, 34, 36) between the supervision terminal and each of a plurality of remote terminals (33) connected to the supervision terminal via a data network (35). The remote terminals may be used to emulate a line interface for monitor devices such as fire alarms (31), while providing continual assurance of the integrity of the link between the supervision terminal and the alarm.
