1. A telemetry system including:
- one or more supervision terminals;
one or more remote terminals associated with at least one of the one or more supervision terminals;
a data network linking the one or more supervision terminals and the one or more remote terminals via an always-on connection through the data network via a path between the one or more supervision terminals and the one or more remote terminals;
wherein;
the one or more supervision terminals is in communication with one or more corresponding associated remote terminals across the data network using network facilities of the data network for carriage and switching or routing of messages;
wherein messages from the one or more remote terminals to the one or more supervision terminals are transmitted across the network, the message content being passed transparently across the network between the one or more remote terminals to the one or more supervision terminals;
wherein the one or more supervision terminals monitor the integrity of the path between the one or more remote terminals according to a fixed or programmable routine; and
wherein the one or more supervision terminals monitor poll responses from the one or more remote terminals to determine path integrity.

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.

19. A method of transmitting information in a telemetry system including:
-
one or more supervision terminals; one or more remote terminals associated with the at least one or more supervision terminals; a data network linking the one or more supervision terminals and the one or more remote terminals via an always-on connection through the data network; the method including the steps of; monitoring the one or more remote terminals from at least one of the one or more associated supervisions terminals via the data network using the network facilities for carriage and switching or routing of messages; transmitting messages from the one or more remote terminals to the one or more supervision terminals across the network, the message content being passed transparently across the network between the one or more remote terminals to the one or more supervision terminals; and monitoring the path integrity between the one or more supervision terminals to the one or more remote terminals by transmitting poll requests from the one or more supervision terminals to the one or more remote terminals and monitoring poll responses from the one or more remote terminals according to a fixed or programmable routine; and wherein the one or more supervision terminals monitors poll responses from the one or more remote terminals. - View Dependent Claims (20, 21, 22, 23)
