ACKNOWLEDGMENT DELAY TIME
        Default: 3                              Value: 0-65

        Maximum amount of time in seconds that an acknowledgment is to be
        withheld. You cannot modify this characteristic.

     CONGESTION AVOIDANCE
        Default: True                           Value: Boolean

        Enables the use of the automatic congestion avoidance mechanism. This
        mechanism reduces the transport window size in response to an indication
        from the Network layer.

     DELAY FACTOR
        Default: 2                              Value: 2-15

        Factor by which to multiply the current value of the roundtrip delay
        estimate status attribute in order to set a value for the
        retransmission timer.

        NOTE - the roundtrip delay estimate is an attribute of the nsp port
               entity.

     DELAY WEIGHT
        Default: 3                              Value: 0-255

        Relative weighting to apply to the current estimate and to a new sample
        when estimating roundtrip delay.

     DNA VERSION

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

     KEEPALIVE TIME
        Default: 60                              Value: 1-65535

        Time in seconds that NSP waits for data to be transmitted or received
        before testing a transport connection. When this timer expires, NSP
        sends a data request PDU to the remote NSP. This PDU does not change
        the flow control parameters, but does require acknowledgment.

     MAXIMUM RECEIVE BUFFERS
        Default: 2000                            Value: 1-65535

        Maximum number of receive buffers that can store received transport PDUs.
        You may not decrease the value while NSP is enabled.

     MAXIMUM REMOTE NSAPS
        Default: 201                             Value: 1-65535

        Maximum number of remote NSAPs that can exist concurrently. 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.

     MAXIMUM TRANSPORT CONNECTIONS
        Default: 200                             Value: 0-65535

        Maximum number of active transport connections allowed at one time.
        Must not be less than the current value of maximum remote NSAPs. You may
        not decrease the value while NSP is enabled.

     MAXIMUM WINDOW
        Default: 8                               Value: 1-2047

        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 cannot modify this characteristic.

     NSAP SELECTOR
        Default: 32                              Value: 0-256

        NSAP selector used by the nsp entity when opening a port to a network
        service.  You cannot modify this characteristic.

     RETRANSMIT THRESHOLD
        Default: 5                               Value: 1-65535

        Maximum number of times a source nsp entity is to restart an expired
        retransmission timer before the remote node is to be considered
        unreachable. When the threshold is reached, NSP sets the confidence
        variable to false.
