Avaya TN744E Call Classifier Detector circuit pack for Definity and Communication Manager systems.

The Avaya TN744E is a Call Classifier Detector circuit pack designed for use in Avaya Definity and Communication Manager PBX systems. This board provides call progress tone detection and classification capabilities, enabling the system to identify and respond to various telephony signals such as dial tones, busy signals, ringback tones, and answering machine detection.

The TN744E is primarily deployed in call centre and unified communications environments where automated call handling requires accurate detection of call states. It supports applications including predictive dialling, automated attendant functions, and outbound campaign management where distinguishing between live answers, voicemail, and network tones is critical.

This is a legacy circuit pack from the Avaya Definity/Communication Manager era. While these systems remain in active service at many enterprise sites, the TN744E is no longer in production. Refurbished units provide a cost-effective option for maintaining existing infrastructure or sourcing spares.
