The Bfv API Functions

For voice applications, infopkts provide an easy means to build sophisticated interactive voice systems. Using infopkts, a voice application can create a master prompt file that builds all of the system's prompts out of short phrases.

This scheme:

„Reduces the amount of disk space needed for storage.

„Enables the application to build new prompts as changing demands on the system dictate.

„Simplifies the development of multilingual systems that can translate recorded prompts to other languages on-the-fly.

For fax applications, infopkts provide a flexible means to transmit a complex, computer-generated fax document.

A fax transmission consists of one or more documents. A document consists of one or more pages containing the document parameters, agreed upon by two communicating fax machines according to the T.30 protocol, that do not change. A page consists of one or more strips of data, converted from their original format to the established document format for transmission.

To a fax machine, a document is a simple object with three parameters: vertical resolution, length, and width. To a computer, a document is often more complex.

For example, fax applications might require the transmission of ASCII data in fax format. The fax module converts the ASCII data to G3 format in real-time. A file header and signature, already in

G3 fax format, can accompany the ASCII data. The infopkt structure makes it easy to send a document of this type because it organizes fax and ASCII data into a single structure for transmission and reception.

The Bfv API defines and supports the infopkt types described on the following pages:

„Tag Infopkts

„Data Infopkts

„Indirect Infopkts

„User-Defined Infopkts
