Description: Calling Tone Detection Algorithm, one of the enum value, g726-32k(3) is obsoleted on 01Mar99 such that user would not be able to configure CE-ATM

What is cirEmAtmSpvcVccCngToneDetectionA2B?

This OID controls the tone detection algorithm for the A-to-B direction, identifying calling and comfort noise tones that signal connection state and tone generation. Engineers set this during VoATM configuration to ensure the far-end system recognizes dialing tones and knows when the call is active or idle. For example, enabling tone detection with G.711 codec means the circuit will detect dial tones and alert tones, whereas G.726 codecs lack this capability.
