Using the TSPC DLL for Custom Applications
All of the following DLL example programs use Microsoft’s Excel (97 or higher) for the programming environment. Though various development environments can utilize the DLL’s, such as Visual C++, Visual Basic, LabView, HP VEE among others, Excel was chosen as being a common application available to a large user base. Versions of the DLL are available for both 16 bit and 32 bit applications; however, these examples use the AiTspc.dll, which is meant for 32 bit Windows 95/98 applications. Other DLL’s are available for 32 bit NT/2000 applications, or 16 bit Windows 3.1 applications.
The various DLL files and a demonstration program (DDP1100 - 16 bit only) are available for download and function with the AI-150 and AI-410 products. Running the DDP1100 setup program automatically installs the required files in order to use the following Excel files.
| Name | Format | Size | |
|---|---|---|---|
| Generate OSI and Re-order Tone Create an Open Switching Interval (OSI) with a duration of 800 msec, which is then followed by the re-order tone (480 Hz & 620 Hz, 250 msec on, 250 msec off). | Excel File | 68 KB | Download  |
| Send Type 1 (on-hook) Caller ID Message Ring telephone for 2 seconds, then send a FSK Multiple Message format Caller ID signal containing date/ time and calling number information. | Excel File | 72 KB | Download |
