What is cirEmCirEmPvcEchoCancellationB2A?

This OID controls whether echo cancellation is turned on or off for traffic flowing from side B to side A on a CIR circuit (opposite direction from the A2B version). Engineers enable this independently from A2B echo cancellation because the two directions might have different echo issues. You would set this to "on" when the return path of a voice circuit produces noticeable echo.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.6.10.1.9
snmpwalk -v2c -c public <target> ACMIB::cirEmCirEmPvcEchoCancellationB2A

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.6.10.1.9.1
snmpget -v2c -c public <target> ACMIB::cirEmCirEmPvcEchoCancellationB2A.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.6.10.1.9.1 i <value>
