Abstract

PURPOSE:To eliminate the need for setting of BC/LLC in advance in a terminal adaptor connecting to an ISDN. CONSTITUTION:When an automatic dial command and network information are entered from a DTE such as a personal computer, a terminal adaptor receives them and analyzes the command so as to discriminate whether or not the command is normal and whether or not the command is an automatic dial command (steps 1, 2, 3). When it is discriminated that the command is the automatic dial command, the presence of setting information of BC/LLC is discriminated and when the setting information is in existence, the BC/LLC is set to a setting register (steps 4, 5). Then the setting state of the BC/LLC is read from the setting register and transmission is implemented to a destination having an address designated by the automatic dial command (step 6).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal adapter connected to an ISDN for a DTE (D
At the time of automatic transmission by command control from the ATA Terminal Equipment, BC (Bea
Rer Capability: transmission capacity) / LLC
(Low Layer Compatibility:
Automatically set the network information (low layer compatibility),
It is related to the technique of transmitting.

[0002]

2. Description of the Related Art Conventionally, a BC in a terminal adapter
Set the / LLC in advance (1) before communication.
Set by operating the setting key of the hard switch (DIP switch, etc.), (2) set by software switch (set by DTE), (3) input AT command from DTE, and communicate by ASCII code of AT command This was done by automatically detecting speed and code units and automatically setting to that mode.

[0003]

However, all of the conventional BC / LLC setting methods described above are
There is a problem that C / LLC must be set. The present invention, as described above, is based on the B
In order to eliminate the problem that C / LLC must be set, BC / LLC is set when automatic transmission is performed by command control from the DTE of a personal computer, etc. It aims at improving the operability from the DTE of.

[0004]

In order to solve the above problems, the present invention sets BC / LLC in a terminal adapter connected to an ISDN based on network information added to an automatic dial command. Then, after the BC / LLC is set, an automatic call is made to the other party of the address designated by the automatic dial command.

[0005]

According to the present invention, since the automatic dialing method for network information is configured as described above, when the terminal adapter receives the automatic dialing command to which the network information is added, the BC / LLC is based on the network information. Then, the call is automatically sent to the other party at the address specified by the auto dial command.

[0006]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is an operation flowchart of a network information automatic setting dial system according to an embodiment of the present invention, and FIG. 2 is a data configuration diagram of a BC / LLC setting register in the embodiment of the present invention.

First, referring to FIG. 1, the DTE of a personal computer or the like.
When the automatic dial command and the network information are input from the terminal adapter, the terminal adapter receives them and analyzes the command to determine whether they are normal and whether they are automatic dial commands (steps 1, 2, 3). ). If it is determined to be an automatic dial command, BC / LL
The presence / absence of C setting information is determined, and if there is setting information, BC is set.
/ LLC is set (steps 4 and 5).

Here, the setting of BC / LLC is performed by software setting with reference to the setting register of FIG.
When an automatic dial command is input from a personal computer or the like, the network information is analyzed and one of the two setting registers is rewritten. Next, the setting state of BC / LLC is read from the rewritten setting register, and the call is sent to the partner at the address designated by the automatic dial command (step 6). If it is determined in step 3 that the command is not an automatic dial command, that command is executed (step 7).

An example using the V25bis command is shown below. [Example] Input command = CRN XX ...... XX; 00:00
1, 01:02, 02:03. Here, CRNXX ... XX is the automatic dial command,
“×× …… ××” indicates the other party's address. Also,";"
Indicates that there is BC / LLC setting information, and "00:
"01, 01: 02, 02: 03" indicates a register number and a parameter number. When the terminal adapter determines that the command is an automatic dial command, it sets the register number and parameter value below ";" × …… ×
Automatically calls x ”(other party's address).

In the above case, referring to FIG. 2, packet switching, asynchronous, 7 bit none stop bit 2,2
Calls are made at a setting of 400 bps. It should be noted that the present invention is not limited to the above embodiments, and various modifications can be made based on the spirit of the present invention, and they are not excluded from the scope of the present invention.

[0011]

As described above in detail, according to the present invention, BC / LL added to the automatic dial command is added.
Change and set BC / LLC based on the network information of C,
Since automatic dialing is performed, it is not necessary to set BC / LLC in advance. Therefore, it is effective when the BC / LLC of communication must be changed for each access partner.

Further, if an application (AP) capable of registering addresses of a plurality of communication partners is used (for example, 0
1 to 20 can be registered, and by simply specifying "01", the call is automatically sent to the other party registered in "01"), and by adding the BC / LLC network information to that address, automatic It is possible to change the setting to the BC / LLC of the other party and perform communication. Then, once the setting is made, it is not necessary to set the BC / LLC from the next time, and the communication with the other party can be performed only by inputting the automatic dial command. Furthermore, if the application is capable of setting the calling time and making an automatic call at that time, unattended communication will be performed without setting BC / LLC with the other party having a different communication class (BC / LLC) for each set time. It becomes possible to do.
