Brief Description
The FX633 detects the audible tone signals used by most of the world's Telecom Systems to indicate
Dial, Ringing, Busy and other conditions found when placing a call. Detection of these call progress
stages is essential to the proper operation of automatic calling products.
The FX633 adds new features to Call Progress monitoring. It detects and indicates separately the "US
Busy" tones, reducing the need to measure "tone cadence" to identify "US Busy". It detects and
separately indicates "Voice" and other signals from Call Progress tones, reducing voice-falsing and
adding voice-answer as a connection prompt.
The FX633 uses the latest signal processing techniques to provide these advantages. It is a low cost,
low power product with superior performance. It is available in the industry standard package.
