CONGESTION AVOIDANCE
         Default: True                              Value: Boolean

         Enables the use of the automatic congestion avoidance mechanism to
         reduce the transport window size in response to an indication from the
         Network layer when operating on the Connectionless Network Service
         CLNS.

     DELAY FACTOR
         Default: 4                                  Value: 2-15

         Factor by which to multiply the current value of the round-trip delay
         estimate status attribute in order to set a value for the
         retransmission timer.  This attribute works with protocol class 4 only.

     DELAY WEIGHT
         Default: 5                                  Value: 0-255

         Relative weighting to apply to the current estimate and to a new sample
         when estimating round-trip delay.  This attribute works with protocol
         class 4 only.

     DISCONNECT HOLDBACK
         Default: 0                           Value: 0 - ( 2 to the 23 )

         When operating over the Connection-Oriented Network Service CONS, the
         length of the time to maintain a network connection for possible reuse
         after all transport connections multiplexed upon it have been
         disconnected.  Specified in seconds.  This characteristic may not be
         changed while the transport entity is enabled.

     ISO VERSION

         Version number of ISO 8073 to which the implementation conforms. You
         cannot modify this characteristic.

     MAXIMUM MULTIPLEXING
         Default: 2 to the 23rd    Value: 1 - ( 2 to the 23rd)

         Maximum number of transport connections that can be multiplexed on a
         single network connection operating over the cons. You can modify
         this characteristic to a lower value only when the entity is disabled.
         This attribute applies only if X.25 has been configured in the kernel.

     MAXIMUM NETWORK CONNECTIONS
         Default: 2000                        Value: 1 - ( 2 to the 23rd)

         Maximum number of concurrent network connections that the OSI
         transport protocol can use when operating over the cons. You can
         modify this characteristic to a lower value only when the entity is
         disabled.

     MAXIMUM MULTIPLEXING

         When operating over the Connection-Oriented Network Service CONS, the
         maximum number of transport connections that can be multiplexed on any
         single network connection.  This characteristic can be increased only
         when the transport entity is enabled. You can modify this
         characteristic to a lower value only when the entity is disabled.

     MAXIMUM NETWORK CONNECTIONS

         When operating over the  Connection-Oriented Network Service CONS,
         the maximum number of network connections which can be in use
         concurrently by DNA OSI Transport.  This characteristic can be
         increased only when the transport entity is enabled.

     MAXIMUM RECEIVE BUFFERS

         Maximum number of receive buffers that can store received DT transport
         PDUs. You can modify this characteristic only when the entity is
         disabled. Also, you can only increase the characteristic value.

     MAXIMUM REMOTE NSAPS

         Maximum number of remote NSAPs that can exist concurrently.  This value
         must be greater than the current value of maximum transport
         connections. You can modify this characteristic to a lower value only
         when the entity is disabled.  This characteristic can be increased when
         enabled.

     MAXIMUM TRANSPORT CONNECTIONS

         Maximum number of active transport connections allowed at one time.
         Must be less than the current value of maximum remote nsaps. You can
         modify this characteristic to a lower value only when the entity is
         disabled.

     MAXIMUM WINDOW
         Default: 8                                Value: 1-65535

         Maximum credit window that can be granted on a transport connection.
         This is used for control of the number of data segments PDUs allowed
         to be transmitted over a particular transport connection before at
         least one acknowledgment must be returned from the destination system.
         If the number of PDUs already transmitted equals the maximum window
         and no corresponding acknowledgments have been received, transport
         stops sending PDUs over the transport connection and waits for an
         acknowledgment message. You can modify this characteristic to a lower
         value only when the entity is disabled.

     NSAP SELECTOR
         Default: 33                                  Value: 0-255

         The NSAP selector to use for the Connection-Oriented Transport Service
         COTS when running over CLNS.  If 0 or 1, COTS over CLNS is not enabled.
         This attribute cannot be set to 32, which is the value of the NSP NSAP
         selector. Or, on DEC OSF/1, to the current setting of the osi transport
         attribute cltp nsap selector if it is other than 0 or 1.

         This attribute cannot be modified when transport is enabled.

     SUPPORT MAP
         Default: None                                   Value; False

         Specifies whether the implementation supports the MAP manufacturing
         automation protocol entity. You cannot modify this characteristic.

     VERSION

         Version number of the DNA OSI Transport architecture specification to
         which the implementation conforms.  You cannot modify this
         characteristic.
