Avaya Definity TN744E
Call Classifier Tone Detector
for Multiple Countries (8-Port)
Avaya TN744E provides 8 ports of tone detection on the TDM although it does not support call progress tone generation or clocking. It provides tone generation and detection for R2-MFC DID signaling used in no-US installations.
The TN744E allows gain or loss to be applied to pulse code modulation (PCM) signals received from the bus. It detects 2025 Hz, 2100 Hz, or 2225 Hz modem answerback tones and provides normal broadband and wide broadband dial tone detection. The TN744E also supports digital signal processing of PCM signals on each port to detect, recognize, and classify tones and other signal.
We sell new and remanufactured TN744E cards.
