Abstract

PURPOSE:To enable a parameter from a remote place to be set by sending the designated instruction information of the parameter by using the incoming sub address of a call setting message. CONSTITUTION:When the call setting message S is received from an ISDN, a decision processing part 15 decides whether or not conversion information setting instruction information to instruct the parameter setting of a terminal adapter exists in the incoming sub address in the call setting message S. When the conversion information setting instruction information is set, a response to the ISDN is returned, and line connection is performed, and also, a conversion information setting processing part 14 is started up, and a mode is switched to the one to set the parameter. Conversion information included in conversion information setting data R received after the line connection is set at a storage part 11. When no conversion information setting instruction information is set, the mode is set as the one to handle an ordinary incoming signal, and the response is returned to the ISDN.

[Detailed description of the invention]

C Overview] Concerning a parameter setting method for remotely setting the control parameters of a terminal adapter TA used to connect an existing terminal TE to an l5DN network (integrated service digital communication network), parameter settings can be easily and efficiently performed remotely. A storage unit that stores conversion information for converting communication information between a communication network and a terminal into a format required by the terminal; In an interface circuit having a signal conversion processing unit for converting, a determination processing unit that determines whether a destination subaddress of a call setting message is conversion information setting instruction information that instructs setting of the conversion information, and a determination processing unit that stores in the storage unit a conversion information setting processing unit that sets the conversion information that has been converted using conversion information setting data that includes the conversion information that is received from the network after line connection; When the information setting is recognized, the conversion information is set in the storage unit using the conversion information setting data received after the line is connected. [Industrial Application Field] The present invention is applicable to ISDNm (Integrated Service Digital Communication Network)
The present invention relates to a parameter setting method for remotely setting control parameters of a terminal adapter TA used to connect an existing terminal TE to a terminal TE. Usually, an I5DN-dedicated terminal is connected to the I5DN cable, and the communication procedure between them is CCITT such as 2B+D channel format.
The recommended I interface is used. On the other hand, l5DN
When connecting an existing terminal to the network, the communication procedure of the existing terminal (
Since the existing protocol) is different from the above-mentioned I interface, a terminal adapter TA is used to perform protocol conversion and speed conversion. It is necessary to set various parameters for this terminal adapter TA, such as speed, parity consistency, and address information required by the connected terminal, depending on the data terminal and analog terminal to be connected. The speed parameter is the type of transmission speed between the terminal adapter TA and the terminal, for example 300 bps.
~64 kbps is set. The parity parameter indicates the type of parity, such as even parity and odd parity, for detecting errors. The consistency parameter indicates an attribute that a communication terminal has. For example, when the attributes of communication terminals such as a telephone call or a FAX call match, the communication becomes possible. The address information parameter indicates the type of subaddress or dial-in address that is added when it is desired to identify communication to the terminal itself. [Prior Art] FIG. 8 shows a block diagram of a conventional terminal adapter. In the figure, 21 is a CPU, 22 is a data/analog terminal interface circuit, 23 is a memory, and 24 is a line control section. 25 is a data terminal (or analog terminal),
26 is a numeric keypad for setting parameters; and 27 is a depth inch for setting parameters. Communication speed, parity, consistency, and address information between the terminal adapter TA and the terminal are set in the memory 23. The call setup message from the 15DN network side is sent to the line control unit 24.
The reception is received via the CPU 2, which performs various signal processing.
After a match with the consistency information set in the memory 23 is detected in step 1, protocol conversion and speed conversion are performed, and the signal reaches the receiving terminal 25 via the data/analog terminal interface circuit 22. A communication path between the terminals is established by returning a response message to the terminal adapter TA or the 15DN network in response to the response from the terminal 25. From then on, communication of information signals to the kidney terminal 25 is performed based on the parameters set in the memory 23. On the other hand, the outgoing signal from the terminal 25 is sent to the terminal adapter T.
Based on the information in the memory 23 of A, the CPU 21 performs protocol conversion and speed conversion, creates a call setting message carrying the calling address and calling subaddress, and sends it to the 15DN network side. The conventional parameter setting method for the terminal adapter TA is to connect the start/stop terminal 25' for inputting commands to the data terminal interface circuit 22, or to operate the numeric keypad 26 provided on the terminal adapter TA to store the data in the memory 23. The settings were made by setting the contents or by switching the dip switch 27. [Problems to be Solved by the Invention] In the conventional parameter setting method, there was a problem in that the worker had to go to the site and set the parameters, resulting in poor workability. Furthermore, if the terminal adapter TA does not have the numeric keypad 26 or dip switch 27,
There was a problem in that the start/stop terminal 25' for parameter setting had to be brought to the site, which required a lot of effort. An object of the present invention is to easily and efficiently set parameters remotely. [Means for Solving the Problems] FIG. 1 shows a basic configuration diagram of a terminal adapter according to the present invention. In the figure, 11 is a storage unit, a communication network and a terminal 13
Stores conversion information for converting communication information between devices into the format required by the terminal. 12 is a signal conversion processing section, and the storage section 11
The speed is converted to a speed suitable for the terminal 13 based on the conversion information. Reference numeral 14 denotes a conversion information setting processing section, which sets conversion information stored in the storage section 11. Reference numeral 15 denotes a determination processing unit that determines whether the information included in the destination subaddress of the call setting message S is conversion information setting instruction information indicating an instruction to set conversion information. The present invention has the above configuration, and the first invention is as follows. Upon receiving the call setting message S from the 15DN network, the determination processing unit 15 determines whether the destination subaddress in the call setting message S contains conversion information setting instruction information of the terminal adapter parameter setting instruction. If the conversion information setting instruction information is set, a response is returned to the l5DN network,
At the same time as the line connection is made, the conversion information setting processing section 14 is activated and switched to the parameter setting mode. Then, the conversion information included in the conversion information setting data R received after the line connection is set in the storage unit 11. If the conversion information setting instruction information is not set, the mode is set to handle normal incoming calls, and a response is returned to 15DN@. The second invention is as follows. Upon receiving the call setting message S' from the 15DN network, the determination processing unit 15' determines whether or not the destination subaddress in the call setting message S' includes conversion information setting instruction information for the terminal adapter parameter setting instruction. If the conversion information setting instruction information is set, the conversion information setting processing section 14' sets the conversion information included in the destination sub-address in the storage section 11. If conversion information setting instruction information is not included, the mode is set to handle a normal incoming call, and a response is returned to the 15DN network. [Operation] According to the first invention, when a call setup message S is used and conversion information setting instruction information is included in the destination subaddress, conversion information including conversion information received from the 15DN network side after line connection is transmitted. Conversion information in the storage unit 11 can be set using the setting data R. Further, according to the second invention, by receiving the conversion information included in the call setting message S', it becomes possible to set the conversion information at the call setting stage. 〔Example〕

This determines that the received message is a call setting message. The transmission capability information element d displays transmission function elements such as the transfer rate and transmission capability 5 communication format provided by the 15DN. In addition, the channel identifier e is a channel identification information element for connecting to the 15DN, the calling number f, and the calling subaddress g.
represents the ID of the sending terminal. The called number ri represents the ID of the terminal receiving the call, and the called subaddress i represents the ID of the terminal from which the call is received. According to the present invention, the terminating terminal ID is normally set in this terminating sub-address i, and a parameter setting ID (this is a value that does not overlap with the terminating sub-address, for example, 1r999) indicating a parameter setting instruction is set at the time of parameter setting. . FIG. 2(b) shows the format of this destination subaddress i. The destination subaddress i has columns for a maximum of 19 lines in units of 1 octent. In the first embodiment, the above-mentioned parameter setting ID "999J" is placed using, for example, the 4th line to the 1st line among these 19 lines. Lines 4 to 19 are not used. In addition, low layer consistency j is an indication of capability categories such as transfer speed and transfer capacity, and high layer consistency is the function of the sending terminal's telephone, facsimile, or personal computer.

If the terminal adapter TA has a destination subaddress indicating a normal terminal, the terminal adapter TA performs general incoming call processing for the terminal 32 after connecting the line. However, if the destination subaddress contains the parameter setting instruction ID, after the line is connected, the parameter setting process is performed using the transmission signal of the B channel. FIG. 4 shows a flowchart of a first embodiment of a terminal adapter according to the present invention. FIG. 5 shows a sequence of parameter setting procedures according to the present invention. This will be explained in detail below. In FIG. 4(a) showing the process of determining the destination subaddress, the terminal adapter TA on the destination side is connected to the remote terminal TE3.
A call setting message (2) is received from No. 1 through the JSDN network (step 41). The CPU 21 of the terminal adapter TA determines whether the called subaddress is included in the call setting message (2) (step 42). If the subaddress 1r999 indicating a parameter setting instruction is included (YES in step 43), the line is connected by sending a response message ■ (step 44), and the mode shifts to parameter setting processing mode (step 4).

General incoming signal processing is performed on the terminal (step 46). FIG. 4(b) shows the processing flow in the parameter setting mode. After the line is connected, parameter setting data (2) including setting items and new setting values is sent from the remote terminal TE31 through the connected B channel, and is received by the terminal adapter TA (step 47). The CPU 21 of the terminal adapter TA extracts setting information from the parameter setting data (2) of the B channel, writes it into the corresponding area of the memory 23, and performs parameter setting processing (step 48). In the parameter setting process, the parameter setting process mode is canceled by receiving the disconnection message ■ which is a D channel control signal from the remote terminal TE31 (step 49).

Then, using the remaining 16 lines, two lines of setting item information and setting content information are set as one unit, and a maximum of eight items of parameter setting information are entered and transmitted. FIG. 6 shows the flow of a second embodiment of the terminal adapter according to the present invention. FIG. 7 shows a second processing sequence of the parameter setting procedure according to the present invention. The parameter setting procedure will be explained below. The terminal adapter TA on the receiving side is the remote terminal TE31
A call setting message (2) is received from the terminal via l5DNy4 (step 61). The CPU 21 of the terminal adapter TA determines whether the called subaddress is included in the call setting message (2) (step 62). If the sub-address "999j" indicating parameter setting instructions is in the first line (YES in step 63)
As a parameter setting process, the parameter setting information from the second line onward is written into the memory 23 (step 64). The parameter setting process ends upon receiving the release completion message ■ from the remote terminal (step 66). If there are eight or more parameter setting items, this becomes possible by receiving the call setting message ■ again. If this destination subaddress is a subaddress representing a terminal (NO in step 63), after the line is connected, the terminal TE
General incoming signal processing is performed for the terminal (step 65). In this second embodiment, only a call setting message can be processed, and parameters can be set in the memory without a telephone line being connected, and are not subject to billing. [Effects of the Invention] As explained above, according to the present invention, the parameter setting instruction information is sent using the destination subaddress of the call setting message, so that it becomes possible to set the parameters remotely. Therefore, there is no need to go to the site, improving work efficiency and requiring almost no labor. Furthermore, the parameter setting process can be performed without forming a communication line, and can also be excluded from billing.
