Abstract

PURPOSE:To realize a sophisticated application requiring a tone output with respect to a terminal equipment unable to output a tone by outputting the same tone as requested one to a tone transmission request from an intelligent terminal equipment. CONSTITUTION:In receiving a tone control request 12 from an intelligent terminal equipment 13, an analysis processing section 2 analyzes the content of the request and outputs the result to a tone generating circuit control section 4 via an interface line 3. The control section 4 instructs the tone output requested by the terminal equipment 13 to a tone generating circuit 5 depending on the result of analysis of the processing section 2.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention connects one or more terminals to an ISDN subscriber line, and controls the corresponding tones based on tone control requests from the network to those terminals. The present invention relates to an adapter device for a subscriber terminal having a tone generation circuit that transmits a tone and sends an alarm sound in response to an erroneous operation in the terminal.

[Prior Art] FIG. 2 is a block diagram of a conventional example of this type of subscriber terminal adapter device.

The subscriber terminal adapter device 11 includes a network compatible interface 7, a self-control logic circuit 8, and a self-compatible interface 9.
, a tone generation circuit 5, and are connected to a network side exchange 14 through a subscriber line 10 and to an intelligent terminal 13 through an extension line 6. This subscriber terminal adapter device 11 receives a tone control request 15 from the network side exchange 14.
The network compatible interface 7 analyzes this, and the tone generating circuit 5 sends out a tone based on the instructions.When the self-control logic circuit 8 operates in response to an incorrect operation such as an incomplete call originating from the own terminal, the self-compatible interface 9 detects the corresponding tone. The tone generation circuit 5 is instructed to send out the tone.

[Problems to be Solved by the Invention] The conventional subscriber terminal adapter device described above does not have an interface for receiving tone control requests from terminals.
A drawback is that the tones of the subscriber terminal adapter device cannot be used from the application software of the terminal.

[Means for Solving the Problems] The subscriber terminal adapter device of the present invention includes, upon receiving a tone control request requesting tone transmission from an intelligent terminal, an analysis processing unit that analyzes the content of the tone control request; The tone generation circuit control section includes a tone generation circuit control section that instructs the tone generation circuit to output a corresponding tone based on the analysis result of the analysis processing section.

[Operation] The tone control request sent by the intelligent terminal is analyzed by the analysis processing section, and the tone requested based on the analysis result is output from the tone generation circuit to the requested terminal, so that the intelligent terminal can output the tone. You can use the application software you need.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the subscriber terminal adapter device of the present invention.

This subscriber terminal adapter device 1 has the same network interface 7, self-control logic circuit 8. In addition to the self-compatible interface 9 and the tone generation circuit 5, there is also an analysis processing unit 2 that receives a signal control request 12 from an intelligent terminal 13 and analyzes the content of the control request; The tone generation circuit control section 4 issues a tone output command to the tone generation circuit 5 based on the analysis result of the analysis processing section 2.

Next, the operation of this embodiment will be explained.

Upon receiving the tone control request 12 from the intelligent terminal 13, the analysis processing section 2 analyzes the contents of the request and outputs the result to the tone generation circuit control section 4 via the interface line 3. The tone generation circuit control section 4 is the analysis processing section 2
Based on the analysis result, the tone generation circuit 5 is instructed to output the tone requested by the intelligent terminal 13.

[Effects of the Invention] As explained above, the present invention outputs a tone as requested in response to a tone transmission request from an intelligent terminal, thereby making it necessary for an intelligent terminal that cannot output a tone to output a tone. This has the effect of making it possible to realize advanced applications.
