Select application to view the settable attributes
of an osi transport application, or select template to display the
settable attributes of an osi transport template.
1 – cltp nsap selector (Tru64 UNIX)
Default: 0 Value: 0-255 (except 32)
The NSAP selector to use for CLTS when running over CLNS. If the
value is 0 or 1, a single NSAP is shared between the Connection-
Oriented Transport Service (COTS), and the connectionless
transport protocol according to the osi transport attribute nsap
selector. If both nsap selectors are 0 or 1, then COTS and CLTS
over CLNS are disabled.
This attribute cannot be set either to 32, which is the value
of the NSP NSAP selector, or to the current setting of the osi
transport attribute, nsap selector, if the attribute has a value
other than 0 or 1.
This attribute cannot be modified when transport is enabled.
2 – congestion_avoidance
Default: False Value: True or false
Enables the use of the automatic congestion avoidance mechanism

OSI transport is disabled.
For each cons filter, there must be a corresponding x25 access

20.10 – inbound (OpenVMS)
Default: True Value: True or false
Indicates whether this template may be used as the template for
an inbound transport connection. The algorithm of selection
of the inbound template is different depending on the type of
network service over which the transport connection is made.
If an inbound template cannot be found for an inbound transport
connection, then the template called DEFAULT will be selected as
the default. For the CLNS network service, the inbound template
selected is the first template found that has the Inbound

of the Routing Circuit entity that the transport connection
is using. For the CONS network service, the inbound template
