Avaya TN744E V2 Definity / G3 enterprise PBX PBX Card / Module

The Avaya TN744E V2 is a Call Classifier/Detector circuit pack for Avaya Definity/G3 PBX, a genuine Avaya component for the Definity/G3-generation enterprise PBX platform (the same architecture underlying later Avaya Communication Manager systems). Avaya Definity/G3 systems are widely deployed carrier-class enterprise telephone systems, and this component performs its documented role – Call Classifier/Detector circuit pack for Avaya Definity/G3 PBX – within that platform, whether as a line/trunk interface circuit pack, control/processor pack, or an IP endpoint. As a genuine Avaya part, it is built to slot directly into or connect with its compatible Avaya system. Avaya Definity/G3 systems remain in active service across many established enterprise telephony deployments, and genuine spares such as this one are a routine requirement for maintaining full system capacity, restoring redundancy after a component failure, or expanding an existing installation. Tech-Star (UK-based, shipped worldwide) stocks tested Avaya components to support ongoing PBX maintenance projects. Please contact our sales team for current stock and pricing.
