Call Progress Detector Delivers Visual Waiting Indication

In addition to offering a signal processing technique that outperforms the output falsing and stuck detect performance of older architecture call progress tone detectors, this new detector also provides the rapid speed needed to support stutter dial tone detection for visual message waiting indication. CMX673 call progress tone detector has an operating voltage range of 2.7V to 5.5V and low power requirement of 0.5 mA at 3V. The device is used in public switched telephone network systems, feature phones and wherever call progress tones are required to indicate busy, ringing, not available, and other call progress conditions. When combined with cadence measurement, the rapid-detect response time of the device supports an increased range of call progress functions, especially the stutter dial tone used in voice messaging systems.
