LCN direction
This parameter determines whether the X.25 LCN used for outgoing TPAD calls is
incremented or decremented from the starting value when multiple TPAD instances share
one layer 2 (LAPB or LAPD), connection. The default is “DOWN” and LCNs are decremented,
i.e. if the first CALL uses 1024, the next will use 1023, etc. Setting the parameter to “UP”
will cause the LCN to be incremented from the start value.
On the backup interface
Use NUA
The LCN parameter is used to set the first LCN that will be used for the backup
interface.
Use NUI
This specifies the X.25 Network User Identifier to be used for outgoing X.25 calls if
no NUI is specified in the call string for the backup interface.
LCN
The LCN parameter is used to set the first LCN that will be used for the backup
interface.
LCN direction
This parameter determines whether the LCN used for the backup X.25 interface is
incremented or decremented from the starting value when multiple X.25 instances
share a single layer 2 connection.
Report our NUA as n to the X.25 network
This is the NUA that the unit will report to the X.25 network as its own NUA when making a
call. It is also known as the calling NUA. Often the X.25 network will override this NUA.
Call User Data
This specifies a text string that will be placed in the Call User Data field of an outgoing X.25
call request packet. Whether or not this information is required will depend on the X.25 host
that you are connecting to. In most cases the information is not required.
X.25 calls
These setting controls how transactions are sent to the host when TPAD is running in “direct
mode”.
One per transaction
Only one transaction is allowed per call.
Allow consecutive transactions
Multiple transactions are allowed per X.25 call, but not until a response has been
received from the host.
Allow concurrent transactions
Multiple transactions per X.25 call are allowed irrespective of whether a response has
been received from the host.
Use ASCII character x as the delimiter character
This parameter specifies the character used to separate a main NUA from a backup NUA,
and a main NUI from a backup NUI in an ATD command. The default value is the ASCII “!”
character (decimal 33).
Forward mode time x milliseconds
If not framed with STX and ETX characters, can still have data formatted after this period.
