Description: This field selects the signaling bits as seen in DS1 signal, ab or abcd.

What is twoWireSinkSignalingBits?

This OID reports which signaling bits are currently present in the DS1 (T1/E1) signal, typically either 2-bit (ab) or 4-bit (abcd) format depending on the line protocol. Network engineers need to know this to verify that the correct signaling protocol is configured for voice calls and to debug call setup failures. For example, if the OID shows 'abcd', it means the device is using the full 4-bit signaling pattern, which is required for modern ISDN PRI circuits.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.10.1.5
snmpwalk -v2c -c public <target> ACMIB::twoWireSinkSignalingBits

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.10.1.5.1
snmpget -v2c -c public <target> ACMIB::twoWireSinkSignalingBits.1
