vismLapdIndex
Module: CISCO-WAN-LAPD-TRUNK-MIB
OID (symbolic): CISCO-WAN-LAPD-TRUNK-MIB::vismLapdIndex
OID (numeric): 1.3.6.1.4.1.351.110.5.5.12.1.1.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This is an index to vismLapdTable. This is derived from the following formula: index = 31 * (DS1# - 1) + DS0#
where : DS1# - The T1/E1 line number in the range 1 - 8. DS0# - The DS0 channel number ranging from 1 to 24 for T1 and 1 to 31 for E1.
What is vismLapdIndex?
This object is a unique index identifier for entries in the LAPD (Link Access Procedure for the D channel) trunk table, derived by multiplying the T1/E1 line number by 31 and adding the DS0 channel number. The formula accounts for different channel ranges: T1 lines have 24 channels (DS0 1-24) while E1 lines have 31 channels (DS0 1-31). Operators and management systems use this index to uniquely identify and access individual D-channel configurations across multiple T1 or E1 circuits.
