The PB-100 hardware and software provides inexpensive PC to Telephony applications on an open source basis and makes it easy to create your own application solutions using standard programming languages such as Microsoft???s Visual Basic??.

The PB-100 accepts simple ASCII serial commands to seize the phone line, dial or decode DTMF Touch Tones, watch for busy signal, detect loop status, perform timed hook-switch flashes or hang-up the line. If your PC is equipped with a sound card, the audio ports can also be coupled to the phone line through the PB-100 for voice recording or playing announcements using standard file formats such as .wav files.
The PB-100 hardware features a serial port interface, an ???AUDIO IN??? and ???AUDIO OUT??? port, an analog C.O. line interface and an analog phone port. Several pre-written applications are included and can be installed for use. In addition, all available source code is provided to allow changes or improvements to existing programs.
