Description: Calling Tone Detection Algorithm

What is gr303Aal2PvcVccCngToneDetection?

This OID controls tone detection for calling tones like dial tone and ring tone in voice signals. Network engineers enable this to properly recognize signaling tones that indicate the line state to devices on both ends. Enabling CNG (comfort noise generation) detection lets the system recognize background noise patterns, which confirms the line is alive even during silent periods.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.6.37.1.12
snmpwalk -v2c -c public <target> ACMIB::gr303Aal2PvcVccCngToneDetection

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.6.37.1.12.1
snmpget -v2c -c public <target> ACMIB::gr303Aal2PvcVccCngToneDetection.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.6.37.1.12.1 i <value>
