1 – Characteristics
o clns classes supported
Default: Class {4} Value: Bit-set
Set of protocol classes supported on the Connectionless Networt
Service (CLNS). You cannot modify this characteristic.
o 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.
o congestion avoidance

remove commands can only be used to modify this attribute when the
OSI transport is disabled.
For each cons filter, there must be a corresponding x25 access
template with the same name. One or more of these filters must be

attribute is supported only for class 2 and class 4 protocols.
o 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
attribute set to true , the Network Service attribute set to
CLNS, and the CLNS Inactive Area Address attribute set to empty
set.
For the CLNS network service (using the inactive subset, that
is, null internet), the incoming template selected is the first
template found that has the Inbound attribute set to True, the
Network Service attribute set to CLNS and the CLNS Inactive Area
Address attribute matches the Inactive Area Address attribute
of the Routing Circuit entity that the transport connection
is using. For the CONS network service, the inbound template
selected is the first template found that has the inbound
attribute set to true , the network service attribute set to CONS
and the CONS template attribute (that is, an X.25 Access template
name) matches the name of the X.25 Access filter that was used to
accept the inbound network connection.
o initial retransmit time
Default: 5 Value for Tru64 UNIX: 1-(2 raised to the
power of 31 -1)
Default: 5 Value for OpenVMS: 1-4294967295
Amount of time (in seconds) to wait for an acknowledgment before
retransmitting the first TPDU over the transport connection.
o keepalive time
Default: 60 Value: 1-16383
Time (in seconds) to be used for the window timer. When the
transport service provider has no TPDUs to send over a transport
connection, it retransmits the last AK TPDU at the specified
frequency to prevent expiration of the remote NSAP's inactivity
timer. This attribute is valid for protocol class 4 only.
o local nsap
Default: System Value: NSAP address
dependent, determined
at run-time
A local NSAP address to be used by default if one is not supplied
across the service interface.
o loopback (OpenVMS)
Default: False Value: True or false
Specifies whether transport connections using this template are
looped back locally in the transport layer.
o maximum nsdu size
Default: 2048 Value for Tru64 UNIX: 128-4294967295
Default: 2048 Value for OpenVMS: 2048
When operating over the CONS, the maximum NSDU size to use for
transmit and receive buffers. Expressed as a number of octets.
o network priority (OpenVMS)
Default: 0 Value: 0-255
When operating over CLNS, indicates network priority encoded in
NPDU header for all transmitted packets. It may be used by
intermediate systems to assign the packets to queues of
appropriate priority.
o network service
Default: clns Value: Any, clns, cons, or RFC1006
(OpenVMS)
Type of network service. On Tru64 UNIX, the default template
network service cannot be set to any. The network service
chosen must be compatible with the value of the protocol class
attribute.
any Either
clns Connectionless Network Service
cons Connection-Oriented Network Service
RFC1006 ISO Transport Service on top of TCP
o retransmit threshold
Default: 8 Value: 0-4294967295
Number of times a TPDU requiring acknowledgment is to be
retransmitted before it is assumed that network connectivity
has failed. This attribute is valid for protocol class 4 only.
o RFC1006 port number (OpenVMS)
Default: 102 Value: TCP port number
Specifies the TCP port number to use. Only applicable if the
network service is RFC1006.
o security
Default: Null value Value: Octet string
An octet string to be transmitted in the security parameter of
a CR or CC TPDU. A null value causes the security parameter to
be omitted from the TPDU. For security reasons, this attribute
cannot be displayed.
o send implementation id
Default: None Value: True or false
Indicates whether the implementation id should be sent in the CR if
the proposed protocol class is 2 or 4. It is always returned in the
CC if it is present in the CR.
o send preferred maximum TPDU size
Default: True Value: True or false
Indicates whether the preferred maximum TPDU size parameter should
be sent in the CR TPDU.
If the preferred maximum TPDU size parameter was present in the
CR TPDU, then it indicates whether the preferred maximum TPDU size
parameter should be sent in the CC TPDU.
NOTE
The default value of this characteristic should not be changed
unless the remote implementation does not conform to ISO 8073.
o send request acknowledgment
Default: True Value: True or false
Indicates whether the request acknowledgment parameter should be
sent in the CR TPDU.
If the request acknowledgment parameter was present in the CR TPDU,
then it indicates whether the request acknowledgment parameter
should be sent in the CC TPDU.
NOTE
The default of this characteristic should not be changed unless the
remote implementation does not conform to ISO 8073.
o use clns error reports
Default: False Value: True or false
Indicates whether the network Routing layer's error report
facility should be used when performing connection establishment.
If set to true, this may result in faster detection of an
unreachable node at the time of connection establishment. This
characteristic should not be set to true on an end system that
is either dual-railed or connected to a network that has a high
probability of duplication. This is valid only if network service
equals clns.
6.2 – Identifier
o name
Simple name assigned to the template when it is created. The name
default is reserved.
