Product Overview
The Avaya TN763C provides auxiliary analog trunk functionality for enterprise PBX installations. It enables communication between DEFINITY systems and external devices that support paging, announcements, background music, and specialized analog communication services. Maintaining these interfaces is essential in hospitals, manufacturing plants, educational campuses, transportation facilities, and large commercial buildings where legacy PBX systems remain operational.
Replacing a failed AUX trunk board with a professionally refurbished TN763C allows organizations to restore communication services quickly while extending the operational life of their existing telephone infrastructure.
