Claims

[Scope of Claim for Utility Model Registration] (1) Comprising a data communication section and a signal input section for inputting signals output from a detector or measuring instrument,
A telephone call or call on a single line based on at least one line selection signal such as a Ministry of Posts and Telecommunications MSS (Multi-Service Switcher) signal, a push button signal, a modem carrier signal, or a facsimile-specific signal. A telemetering terminal that performs facsimile communication and data communication for telemetering and remote monitoring, where the line selection signal is not sent to the line or the line selection signal is sent to the line. a first connection means for connecting the telephone or facsimile device to the line when the content of the line selection signal is for a telephone call or facsimile communication, and when the line selection signal is sent to the line; A telemetering terminal comprising: second connection means for connecting the data communication section to the line when the line selection signal is for telemetering. (2) A third connecting means is provided for directly connecting the telephone or facsimile device to the line when a ringless ringing signal of network F is sent to the line. Telemetering terminal.
