casAddressingType

Module: ACMIB

OID (symbolic): ACMIB::casAddressingType

OID (numeric): 1.3.6.1.4.1.1751.2.18.5.20.1.1.6

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The addressing type used for the CAS trunk/line. dtmf -- dual tone multifrequency r1-mf -- R1 multifrequency, r2-mf -- R2 multifrequency. Type of 're-mf' is valid only when casProtocolType is 'wink start', while 'r2-mf' is valid only when casProtocolType is 'itu-t r2' .

What is casAddressingType?

This OID specifies how telephone numbers are encoded and sent across the trunk—either as DTMF tones (dual-tone multifrequency), R1 multifrequency, or R2 multifrequency signaling. Network engineers choose the addressing type based on regional standards and interoperability requirements; many regions mandate R2 for international calls while others use DTMF for domestic routes. Setting this to "r2-mf" with ITU-T R2 protocol enables proper number transmission to European carriers, whereas "dtmf" works with North American wink-start signaling.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.20.1.1.6
snmpwalk -v2c -c public <target> ACMIB::casAddressingType

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.20.1.1.6.1
snmpget -v2c -c public <target> ACMIB::casAddressingType.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.5.20.1.1.6.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> casAddressingType.1
