cvIfCfgEchoCancelCoverage
Module: CISCO-VOICE-IF-MIB
OID (symbolic): CISCO-VOICE-IF-MIB::cvIfCfgEchoCancelCoverage
OID (numeric): 1.3.6.1.4.1.9.9.64.1.1.1.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The object specifies the Echo Canceller coverage for the interface. This object is valid if the cvIfCfgEchoCancelEnable object is 'true'. echoCanceller8ms - 8 millisecs echo canceller coverage. echoCanceller16ms - 16 millisecs echo canceller coverage. echoCanceller24ms - 24 millisecs echo canceller coverage. echoCanceller32ms - 32 millisecs echo canceller coverage. echoCanceller48ms - 48 millisecs echo canceller coverage. echoCanceller64ms - 64 millisecs echo canceller coverage. echoCanceller80ms - 80 millisecs echo canceller coverage. echoCanceller96ms - 96 millisecs echo canceller coverage. echoCanceller112ms - 112 millisecs echo canceller coverage. echoCanceller128ms - 128 millisecs echo canceller coverage. The default value of this object is echoCanceller8ms or echoCanceller64ms, depending on the particular echo canceller.
What is cvIfCfgEchoCancelCoverage?
This read-write INTEGER selects the Echo Canceller coverage duration (from 8ms up through longer windows) for the interface, and it is only valid when cvIfCfgEchoCancelEnable is true. Administrators tune this to match the expected round-trip echo delay on a given circuit, since too short a coverage window will fail to cancel echo arriving later than the window covers. For example, on a long-haul international trunk with longer echo path delay, an admin would select a longer coverage value than on a short local loop to ensure echo occurring later in the delay window is still cancelled.
