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.Fax Relay is to allow detection of fax Calling Tones. In faxRelay Mode only Fax calling tone is detected . In fxRlyMdmBypass faxRelay is detected and Modem is done in bypass mode

What is cirEmAtmPvcVccCngToneDetectionB2A?

This parameter controls the calling tone detection algorithm used on the B-to-A direction of a fax or voice call, with options like standard fax detection or modem bypass mode. Network engineers configure this when setting up fax relay to ensure the gateway can detect incoming fax calling tones rather than treating them as voice. For example, setting it to 'faxRelay' enables detection of fax calling tones while filtering out voice, whereas 'fxRlyMdmBypass' would bypass fax relay and allow modem detection.
