There are no mechanisms in the X.25 MIB for telling the PLE to place
an X.25 call. Such mechanisms belong in the MIBs for the higher layer
entities that use the X.25 circuits.
3.6. Conformance
All the objects defined here are mandatory. To claim conformance with
this MIB an implementation must support all objects. However some
objects pertain to features that are optional. There are values
defined for those objects that indicate the implementation does not
support the optional feature. The agent for such an implementation
Throop [Page 6]
RFC 1382 X.25 Packet Layer MIB November 1992
must support reading the object and return the value that indicates
the optional feature isn't supported and reject set requests to
change the object.
Some optional features have more than one object that pertain to it
(window rotation has a timer, a count, and a counter for timer
runouts). In such case, any object which indicates the optional
feature isn't supported is sufficient to indicate the feature isn't
supported and the values of the other objects relative to that
feature are undefined.

RFC 1382 X.25 Packet Layer MIB November 1992
SYNTAX SEQUENCE OF X25AdmnEntry
ACCESS not-accessible
STATUS mandatory
DESCRIPTION
"This table contains the administratively
set configuration parameters for an X.25
Packet Level Entity (PLE).
Most of the objects in this table have
corresponding objects in the x25OperTable.
This table contains the values as last set
by the administrator. The x25OperTable
contains the values actually in use by an
X.25 PLE.
Changing an administrative value may or may
not change a current operating value. The
operating value may not change until the
interface is restarted. Some
implementations may change the values
immediately upon changing the administrative
table. All implementations are required to
load the values from the administrative
table when initializing a PLE."
