Teridian 73M1866B/73M1966B FXOAPI User Guide
This guide provides a detailed description of the FXOAPI used with the Teridian M1x66 reference driver. It explains how an application written in C can initialize the API, open devices and channels, configure PCM parameters, and handle asynchronous FXO events through callbacks.
The document lists all available APIs, their prototypes, and usage examples, covering initialization, device/channel management, PCM configuration, hook switching, pulse dialing, GPIO control, loopback, country parameters, billing‑tone filtering, register access, interval‑event tables, current/voltage measurement, and miscellaneous channel settings. Sample code and related documentation references are also included.
