Description: An entry in the DS0 Channel Mapping table. There is an entry in this table corresponding to each ds0 ifEntry within any interface that is channelized to the individual ds0 ifEntry level.

This table is intended to facilitate mapping from channelized interface / channel number to DS0 ifEntry. (e.g. mapping (DS1 ifIndex, DS0 Channel Number) -> ifIndex)

While this table provides information that can also be found in the ifStackTable and dsx0ConfigTable, it provides this same information with a single table lookup, rather than by walking the ifStackTable to find the various constituent ds0 ifTable entries, and testing various

dsx0ConfigTable entries to check for the entry with the applicable DS0 channel number.
