Description

[Detailed Description of the Invention] [Summary] Regarding the improvement of a dial data judgment method for identifying whether or not data input from the outside is data indicating dial information, the special effort required for judgment and conversion processing of dial data is improved. For the purpose of shortening the data as much as possible, internal dial data in a format different from external dial data is stored corresponding to external dial data indicating dial information among external data input from the outside, and external other data other than external dial data is stored. A conversion table that stores internal and other data that can be identified as internal dial data corresponding to the data, and a conversion table that is searched using input external data to identify whether or not the extracted internal data is internal dial data. The configuration is such that an identification means is provided.

[Industrial Application Field] The present invention relates to an improvement in a dial data determination method for determining whether data input from the outside is data indicating dial information.

In recent years, with the diversification of communication information, data terminal devices such as personal computers are attached to telephones, and data is sent and received with the data terminal device attached to the other party's telephone connected via an exchange. Data communication systems are becoming popular.

[Conventional technology]

FIG. 4 is a diagram showing an example of a data communication system to which the present invention is applied.

In FIG. 4, a data terminal device 3 such as a personal computer, for example, is attached to a telephone 2 housed in an exchange 1.

When the telephone set 2 makes a call to another telephone set (not shown) via the exchange 1, the selected dial information (for example, the dial number " Internal circuit dial data DTtl representing 0°" to "9°" and dial codes "*'' and "#") is input to the internal circuit 5 and transmitted to the exchange 1 in a signal format compatible with the exchange 1. As a result, a communication path is established with the other party's telephone.

The internal circuit dial data D7゜ is, for example, the internal circuit dial data DTD-(corresponding to the dial number ゛O゛').
i o) o (however, H indicates hexadecimal display, the same applies hereinafter), internal circuit dial data DTD-(19) corresponding to dial number "9°'", dial code "°"
*Internal circuit dial data corresponding to °° D7゜-(0
3) It is defined as H etc.

If the other party's telephone is also equipped with a data terminal, data communication is possible between the data terminals via a communication path established between the telephones.

Further, the data terminal device 3 sends an outgoing call command in a predetermined format to the attached telephone 2, including dial data (referred to as received dial data DPD) indicating the telephone number of the other party's telephone, for example [CRN Dpl...・・・
By transmitting the DPI, CRLF) in a predetermined code format, such as the ASC[r code, it is also possible to set up a communication path between the telephone 2 and the other party's telephone in the same manner as described above. .

As is well known, the received dial data DPD based on the ASC code is, for example, the dial number "Oo."

Reception dial data Dro corresponding to (30)u, reception dial data DP corresponding to dial number "9°"
11= (39) K, Jirin dial data corresponding to the dial code “NE°°” Dro= (23) H, received dial data corresponding to the dial code “#” [)p
It is defined as pm (2A)H etc.

In such a case, the adapter device 4 provided within the telephone 2
When it identifies that the command transmitted from the data terminal device 3 is a calling command (CRN), it then determines that the received data D is received dial data. When it is confirmed that the received dial data is DPII, the received dial data in ASCII code format [
) ro into an internal circuit dial data judgment unit that can be processed by the internal circuit 5 and then transmitted to the internal circuit 5.

Thereafter, based on the internal circuit dial data determination D transmitted from the adapter device 4, the internal circuit 5 causes the AC 10 to set up a communication path with the other party's telephone in the same manner as described above.

FIG. 5 is a diagram showing an example of a conventional adapter device,

Next, the microphone [J processor (MPU) 41 uses a comparator (CMP) 412 to determine whether the lower received data DPL accumulated in the accumulators (A, C) 411 is (3)H or (A)H. Analytically, in steps 5105 and 3106), if the lower received data DPL is neither (3) nor (A)H, the received data DP is determined to be normal data by 5 degrees different from the received dial data DPD, and abnormal data processing is performed. Execute (step Sl 11).

Further, in step 5103, the comparison unit (CM1') 4

Next, the microprocessor (MPtJ) 41 determines whether the lower received data I) stored in the controller (AC) 4 ] 1 is between (0)++ and E, and (9)□ and below. The comparison unit (CMP) 412 analyzes the lower received data DP1. is less than (0) or greater than (9)□, it is determined that the received data I]2 is abnormal data different from the received dial data conversion process, and abnormal data processing is executed (step 5ill). ).

The comparator (CMI) 412 determines that the lower received data DPL is (3) in the step S 105, and that the F rank received data I) PL is (3) in step 5106.
A), l, and steps 5108 and 5109
, the lower received data DPL is (0)□ or more, and (
9) If the microprocessor (
MPU) 41, the received data DP is the received dial data D
It is determined that it is a PD, and the dial data conversion process shown from step 5121 onwards is executed.

That is, after the microprocessor (MPU) 41 accumulates the higher order received data I) pu in the accumulator (AC) 411 again (step 5121), the microprocessor (MPU) 41 stores it in the save area (Moo).
415 (step 5122), then the lower received data D□- is stored in the accumulator (AC) 411 (step 5123), the register (Y) 414 is stored (step 5124), and then the save area (M, )4
After accumulating the 71st received data D2° that was saved in step 15 in the accumulator (AC) 411 again (step 312
5), accumulate in register (X) 413 (step 51
26).

Next, the microprocessor (MPtJ) 41 converts the received data r)P (received dial data conversion processing) stored in the registers (X) 4.1.3 and (Y) 414 into a continuous read-only memory (ROM). 42 (, Search the provided dial data conversion table 421, extract the stored internal circuit dial data DTD corresponding to the received dial data oeo, and enter the work area (Wo) 41
The upper 4 bits are stored in 6 and the lower 4 bits are stored in the work area (WI) 417 (step S], 27).
.

Next, the microprocessor (MPIJ) 41 transfers the internal circuit dial data I)tn accumulated in the work area (W, ) 416 and (WI) 417 to the transfer area (Z,
) 41 B and (Z, ) 419 (step 3128).

Thereafter, the microprocessor (Ml) 41 transfers the internal circuit dial data D stored in the transfer areas (Z, ) 418 and (Z, ) 419. is transmitted to the internal circuit 5 to cause the telephone 2 to execute call processing to the exchange 1.

[Problem to be solved by the invention]

As is clear from the above explanation, in the conventional adapter device, after analyzing the received data D transmitted by the transmission command from the data terminal device 3 by using the AsC11 code, whether or not it is the received dial data DPD. , when the received dial data is determined to be DPD, it is converted to internal circuit dial data [)to and transmitted to the internal circuit 5, which increases the time required for dial data determination and conversion processing in the adapter device 4. was there.
