The Avaya TN744E is a Call Classifier/Detector circuit pack for the Avaya Definity/G3 PBX platform. It listens on a call and determines whether it has been answered by a person, an answering machine, or a modem/fax tone, feeding that classification back to the system’s call-processing software for features that depend on knowing how a call was answered, such as outbound predictive dialling and certain auto-attendant behaviours.
Definity was AT&T’s and then Lucent’s enterprise PBX, carried forward by Avaya as Communication Manager, and it is built from a cabinet of TN-prefixed circuit packs. Detector and tone/announcement packs handle the system’s own audio processing, alongside line cards for extensions, trunk cards for outside circuits and control packs for the processor complex. The platform ran for decades with the same physical card format, which is why individual packs are still traded and still fit.
