A value that distinguishes this entry from
another entry. Entries in this table are
referenced from other objects which identify
call parameters.
It is impossible to know which other objects
in the MIB reference entries in the table by
looking at this table. Because of this,
changes to parameters must be accomplished
by creating a new entry in this table and
then changing the referencing table to
identify the new entry.
Note that an agent will only use the values
in this table when another table is changed
to reference those values. The number of
other tables that reference an index object
in this table can be found in
x25CallParmRefCount. The value of the
reference count will affect the writability
of the objects as explained above.
Entries in this table which have a reference
count of zero maybe deleted at the convence
of the agent. Care should be taken by the
agent to give the NMS sufficient time to
create a reference to newly created entries.
Should a Management Station not find a free
index with which to create a new entry, it
may feel free to delete entries with a
reference count of zero. However in doing
so the Management Station much realize it
may impact other Management Stations.
