In general, a telemetering system means that a meter reading center uses a subscriber's electricity, water, gas, and hot water to remotely read through a public switched network. In other words, the meter is accessed and measured automatically through the network such as telephone network, leased line, electric wiring line, cable broadcasting line and CATV in order to automate the meter reading work by communication and computer. Among the various types of networks, it is common to use the largest telephone network in terms of size.

In the prior art, when a host computer, which is a meter reading center, sends a metering command to an exchange matching device, the exchange matching device receives and transmits various usage information of the subscriber stored in the subscriber interface to the host computer through the exchange.

In such a system, one-way communication is performed in which the subscriber's various usage information is transmitted only at the command of the host computer, which is the meter reading center, so that information on the subscriber's information such as fire, theft, gas leakage, and crime prevention is received. It didn't have the ability to send to. Therefore, a telemetering service method that can transmit the subscriber's alarm information to the meter reading center has emerged.

And a subscriber interface unit 70 for interfacing with the multiplexer 60 through the unit 40, the telephone 30, and the switch 20.

The telemetering system using the public switched network configured as described above has provided the metering center with a number of benefits to reduce the labor cost for the personnel involved in the inspection work by visiting Kagaho Lake and to protect the personal privacy of the subscriber. In order to implement the meter reading service, the minimization of the impact from the viewpoint of service quality, operation and maintenance of the existing telephone network, and the priority of the telephone service are guaranteed to the maximum, and information exchange can be performed by using a telephone line connected to the public switched network. Increasingly, when expensive intermediate media are needed and used for crime, the purpose of crime prevention and meter reading is lost by cutting lines connected to meter reading and crime prevention centers.

Accordingly, the present invention was devised to solve the above problems, and does not affect the quality of service, operation, and maintenance of the telephone network for connecting to the public switched network, and does not use expensive intermediate equipment for accessing the telephone network. Using a two-way paging system, which solves the big problem that the two-way paging terminal connected to the service providing sensors can be connected wirelessly and the telephone line connected to the public switched network can be cut off in case of a crime.
