isdnChanType
Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::isdnChanType
OID (numeric): 1.3.6.1.4.1.277.4.1.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: type of logical port 0 => isdn b-channel, 1 => sw56
What is isdnChanType?
This read-write value specifies the type of logical port: 0 for an ISDN B-channel, or 1 for sw56 (switched 56 kbps service), determining which signaling/service behavior applies to this logical port. This distinction matters because sw56 and ISDN B-channel have different call-setup and bandwidth characteristics that the switch must handle differently. An engineer provisioning a legacy switched-56 circuit rather than a native ISDN B-channel would set isdnChanType to 1 to ensure the switch applies sw56 call handling instead of ISDN signaling.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.4.1.1.3 snmpwalk -v2c -c public <target> CASCADE-MIB::isdnChanType
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.4.1.1.3.1 snmpget -v2c -c public <target> CASCADE-MIB::isdnChanType.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.277.4.1.1.3.1 i <value>
