| Description | These objects contain the parameters that
can be varied between X.25 calls. The
entries in this table are independent of the
PLE. There exists only one of these tables
for the entire system. The indexes for the
entries are independent of any PLE or any
circuit. Other tables reference entries in
this table. Entries in this table can be
used for default PLE parameters, for
parameters to use to place/answer a call,
for the parameters currently in use for a
circuit, or parameters that were used by a
circuit.
The number of references to a given set of
parameters can be found in the
x25CallParmRefCount object sharing the same
instance identifier with the parameters.
The value of this reference count also
affects the access of the objects in this
table. An object in this table with the
same instance identifier as the instance
identifier of an x25CallParmRefCount must be
consider associated with that reference
count. An object with an associated
reference count of zero can be written (if
its ACCESS clause allows it). An object
with an associated reference count greater
than zero can not be written (regardless of
the ACCESS clause). This ensures that a set
of call parameters being referenced from
another table can not be modified or changed
in a ways inappropriate for continued use by
that table. |
