What is twoWireSourceTestMode?

This read-write OID enables or disables diagnostic test modes on the two-wire source card (such as loopback or tone testing) for temporary troubleshooting purposes. Network engineers enable test mode only during active debugging of call quality or line connectivity issues, then immediately disable it to restore normal call processing, as test modes prevent regular call handling. Setting this to 'OFF' is the normal operating state; setting it to 'loopback' or 'localLoop' enables testing where the card echoes audio back for diagnostics.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.7.1.9
snmpwalk -v2c -c public <target> ACMIB::twoWireSourceTestMode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.7.1.9.1
snmpget -v2c -c public <target> ACMIB::twoWireSourceTestMode.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.2.7.1.9.1 i <value>
