ADAPTIVE DIGITAL TELEPHONY INDEX

ACOUSTIC BEAMFORMER

Acoustic Beamformer C54x

The Adaptive Digital Acoustic Beamformer improves the signal to noise ratio of speech signals by coherently summing signals obtained from a linearly-spaced microphone array.
-------------------------------------------------

AUTOMATIC GAIN CONTROL

AGC - Auto Speech Level Adjustment C54x , C55x , C64x , C64x+

The Adaptive Digital Technologies Automatic Gain Control (AGC) algorithm is used to automatically adjust the speech level of an audio signal to a user selected value.
-------------------------------------------------

ARBITRARY TONE DETECTOR

ATD - Detects User Defined Tones C54x , C55x , C64x

Adaptive Digital’s Arbitrary Tone Detector software detects user-defined tones. This software finds use when the user needs signaling tones other than the standard DTMF and MF tones.
-------------------------------------------------

CONFERENCING

Conferencing C54x , C55x , C64x

The Adaptive Digital Technologies Conferencing software is designed to provide conference call capability to telephone systems. The conferencing algorithm adds the active conference input signals together to form a composite signal. Before sending the composite signal back to each conference party, that party’s transmission is removed from the composite signal to avoid the perception of echo.
-------------------------------------------------

ADT DTMF

Dual Tone Multi Frequency C54x , C55x , C64x

The Adaptive Digital Technologies detector is a carrier class detector that provides exceptional channel densities.
-------------------------------------------------

ADT NOISE REDUCTION

NR - Voice Quality Enhancement C54x , C55x , C64x

Adaptive Digital has two classes of noise reduction algorithms. They are distinguished by a number of characteristics: Standard (noise reduction) and Low Complexity (noise suppression).
-------------------------------------------------

ADT MF R1 R2

Multi- Frequency SIGNALING TONE
C54x , C55x , C64x, C64x+

The Adaptive Digital Technologies Signaling Tone detector is a carrier class Signaling Tone detector that provides exceptional channel densities.
-------------------------------------------------

ADT TONE DETECT & SUPRESS

Signaling Tone Detector C54x , C55x , C64x, C64x+

The Adaptive Digital Technologies Signaling Tone Detector is a carrier class Signaling Tone detector that provides exceptional channel densities.
-------------------------------------------------

ADT TONE GEN

Call Progress Tone Generator C54x , C55x , C64x

Adaptive Digital’s Call Progress Tone Generator software generates telephony call progress tones such as reorder, dial-tone, etc.
-------------------------------------------------

ADT TONE RELAY

Signaling Tone Passer C54x , C55x , C64x

Adaptive Digital’s Tone Relay is a carrier class Signaling Tone passer that provides exceptional channel densities.
-------------------------------------------------

ADT VAD / CNG

Voice Activity Detector/ Comfort Noise Generator C54x , C55x , C64x, C64x+

Adaptive Digital’s VAD/CNG software performs voice activity detection and comfort noise generation. It is used in systems that used reduced bandwidth channels during silent or non-voiced portions of a conversation.
