The Zarlink VoicePath™ API-II software contains a series of functions that pass their input arguments to the VCP and trigger the execution of a VCP routine. The software package also includes a test library that uses the basic VoicePath API-II testing functions to implement a series of high-level tests. The following testing functions are supported by the API-II: Open DC and AC voltage measurements Differential AC voltage measurement AC and DC resistance measurement Three-Element resistance measurement DC and AC current measurements Keypad Test (to support DTMF and Pulse Dial Measurements) Active & Passive noise measurement with various filter options Single, dual, quad tone output (for line testing) Draw and Break dial tone Hybrid loss measurement REN measurement (capacitive load REN measurement) The VCP Package Supported Line Circuit Configurations Host Code Document and source code for high-level algorithms. Host Algorithms API-II Software Host Controller Application Programming Interface (API) that presents a unified programming interface to all of Zarlink’s Voice Termination Devices (VTD).
