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."

DESCRIPTION
"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."

5. Appendix: Revision History July 30 1992 The July, 1992 release (Editor's Internal Reference Number 2.14) made the following changes: The syntax of the index objects for tables that are congruent with the MIB-II ifTable were changed to ifIndexType. The x25CallParmRefCount object was added to the x25CallParmTable. The description of the x25CallParmTable and x25CallParmIndex objects were changed to only allow writing an entry with a zero reference count. A requirement for conformance was added after the definition of x25 in the ASN.1 definition. June 26 1992 The June 29, 1992 release (Editor's Internal Reference Number 2.12) made the following changes: The range of x25ChannelLIC was changed from (0..4096) to (0..4095). The range of x25ChannelHIC was changed from (0..4096) to (0..4095). The range of x25ChannelLTC was changed from (0..4096) to (0..4095). The range of x25ChannelHTC was changed from (0..4096) to (0..4095). The range of x25ChannelLOC was changed from (0..4096) to (0..4095). The range of x25ChannelHOC was changed from (0..4096) to (0..4095). The range of x25CircuitChannel was changed from (1..4096) to (0..4095). The range of x25ClearedCircuitChannel was changed from
(1..4096) to (0..4095).
June 1992
The June 92 release (Editor's Internal Reference Number 2.11)
made the following changes:
A value of dxe was defined for x25AdmnInterfaceMode and
x25OperInterfaceMode.
The objects in the x25ChannelTable can now have a value
of zero to indicate no channels configured in the range.
The length of an X121Address was extended to 17 to
accommodate the 1988 CCITT X.25 standard.
Some object descriptions have been expanded and
simplified, these include: all the channel table objects
except the index, x25AdmnDataRxmtCount,
x25AdmnRejectCount, x25AdmnRegistrationRequestCount,
x25OperDataRxmtCount, x25OperRejectCount,
x25OperRegistrationRequestCount, x25CircuitEstablishTime,
x25ClearedCircuitTimeEstablished,
x25ClearedCircuitTimeCleared, x25CallParmIndex,
x25CallParmInPacketSize, x25CircuitCalledAddress,
x25CircuitOriginallCalledAddress,
x25CircuitCallingAddress, x25CallParmFastSelect,
x25CallParmCug, x25CallParmCugoa, x25CallParmBcug,
x25CallParmNui, x25CallParmRpoa, x25CallParmCallingExt,
x25CallParmCalledExt, x25CallParmProtection,
x25StatInCallRefusals and x25CallParmOutPacketSize.
The x25StatNumberPvcs object was deleted and
x25AdmnNumberPVCs and x25OperNumberPVCs objects added.
The object x25StatOutDataPackets was added.
The object x25AdmnProtocolVersionSupported as added.
The x25CircuitRemoteDteAddress was deleted.
Some ASN.1 errors were corrected.
April 1992
The April release (Editor's Internal Reference Number 2.8)
made many changes to incorporate the comments of the working
group meeting in March 1992.
All reference comments were changed to reference fields.
The type PositiveInteger was imported from the RFC1381-
MIB and used for all index and timer values.
The x25PleTable was split into the x25AdmnTable,
x25OperTable, and x25StatTable.
The timer and counter objects from the x25CircuitTable
were moved to the x25AdmnTable and replicated in the
x25OperTable
The objects in the x25CircuitTable were reordered to put
the non-integer objects at the end of the table for
easier implementation.
The called and calling extension character set was
extended to include a-f, and A-F.
Additional states were added to the x25CircuitStatus
object.
Additional values were added to x25CircuitDirection
x25CircuitCallParamId, and the addresses in the Circuit
Table for PVCs.
The length of the X25Address was changed to 0..15.
The objects x25ClearedCircuitTimeEstablished,
x25ClearedCircuitInPdus, and x25ClearedCircuitOutPdus
were added to the x25ClearedCircuitTable.
The name of the x25CircuitName was changed to
x25CircuitDescr and the description was expanded.
The access of the x25CircuitCallParamId was changed to
read-only.
The x25ClearedCircuitCodes object was split into the
x25ClearedCircuitClearingCause and
x25ClearedCircuitDiagnosticCode objects.
The semantics of the x25ClearedCircuitIndex was
redefined.
Some of the description clauses were changed in an
attempt to add clarity.
DEFVAL clauses were added to most objects in the
x25CallParmTable.
Additional text was added to the description section to
provide an overview of the tables of the MIB.
The minimum allowable value for maximum active circuits
was changed from one to zero.
February 1992
The February release (Editor's Internal Reference Number 1.14)
made many changes.
Many of the tables were combined. For example, the
x25InfoTable, x25PktStatTable, and x25TmrStatTable were
combined into the x25PleTable. The x25ConInfoTable,
x25ConStatTable, and x25ConTimrTable were combined into
the x25CircuitTable.
The objects for call parameters were drastically
reworked. All call parameters were combined in the
x25CallParmTable. Any table, such as the x25PleTable or
x25CircuitTable, that needs to reference call parameters
identifies an entry in the new table. As part of this
the x25ConDefTable was deleted and replaced with the
x25PleDefCallParamId.
The x25PvcTable was deleted; the x25CircuitStatus object
provides similar information about PVCs.
The x25ClearedCircuitTable was added to record the status
code of cleared circuits.
Many object definitions were restructured. For example,
the time units for timers was changed from 1/100ths of a
second to milliseconds. Some indexes into tables were
replaced with object identifiers.
Much of the introductory text was changed and the
references were changed to match.
October 1991
The October release (Editor Internal Reference Number 1.10)
made the following changes:
Changed x25ConInfoStatus to clarify the description and
the pvcResetting(5) value was changed to pvcResetting(6)
to avoid a conflict with a previous use of the number 5.
The name of the counter object
x25TmrStatRetryCountsExceeded was changed to
x25TmrStatRetryCountExceededs.
The name of the counter object
x25TmrStatClearCountsExceeded was changed to
x25TmrStatClearCountExceededs.
All occurrence of Guage was changed to Gauge.
Added the x25CallFcltyTable, x25CallFcltyCcittTable, and
x25CallParamTable.
June 1991
The June release corrected some syntax errors and cleaned up
some other minor things.
April 1991
The April 26 release of this document was the first release.
That version was derived from the ISO work on network layer
management as presented in ISO/IEC 10733 [11]
