h3cVoiceIfCfgEchoCancelDelay
Module: A3COM-HUAWEI-VOICE-IF-MIB
OID (symbolic): A3COM-HUAWEI-VOICE-IF-MIB::h3cVoiceIfCfgEchoCancelDelay
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.39.13.1.1.1.6
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This object indicates the delay of the echo cancellation for the voice interface. This value couldn't be modified unless h3cVoiceIfCfgEchoCancelSwitch is enable. Unit is milliseconds. It is applicable to FXO, FXS, E&M subscriber lines and E1/T1 voice subscriber line. The default value of this object is 32.
What is h3cVoiceIfCfgEchoCancelDelay?
This OID sets the echo cancellation delay (0-64 milliseconds) to match network round-trip time. Engineers tune it so the canceller can identify and remove echoed speech within the observed delay window. Default 32 ms works for most analog circuits; high-delay international circuits might need 48-64 ms.
