any reason). Using this parameter in conjunction with the backup equivalent, it is possible to
configure the unit to use the supplied NUA to connect over D-channel and the supplied NUI to
connect over B channel (for backup).
On the backup interface LCN
The LCN parameter is used to set the first LCN that will be used for the backup interface.
On 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.
On the backup interface NUI/NUA selection
If both an NUI and an NUA are included in the call string, this parameter allows the unit to
filter one of these out of the X.25 call request.
Enable X.25 Restart Packets
It is normally possible to make X.25 CALLs immediately following the initial SABM-UA
exchange. In some cases however, the X.25 network may require an X.25 Restart before it will
accept X.25 CALLs. The correct mode to select depends upon the particular X.25 service to
which you subscribe. The default value is "On". This means that the unit WILL issue X.25
Restart packets. To prevent the unit from issuing Restart packets set this parameter to "Off".
Restart delay
When the Restarts parameter is "On" the Restart Delay value determines the length of time in
milliseconds that the unit will wait before issuing a Restart packet. The default value is 2000
giving a delay of 2 seconds.
IP Settings
Remote IP address
This field indicates the destination host that will answer the XOT, TCP, SSL, UDP call.
Remote IP Address when using the backup interface
This field indicates the destination host that will answer the XOT, TCP, SSL, UDP call if a
connection via the primary interface has failed and the PAD is configured to backup to a
secondary interface that is using an IP based protocol.
IP Stream port
This is the TCP or UDP port number to use for IP (but not XoT) connections.
IP length header
When set to "On", and in IP Stream mode, the length of a data sequence is inserted before the
data. For the receive direction it is assumed the length of the data is in the data stream. When
set to "8583 Ascii 4 byte", the IP length header will conform to the ISO 8583 format.

PAD Settings

PAD prompt
This parameter allows you to redefine the standard "PAD>" prompt. To change the prompt
enter a new string of up to 15 characters into the text box.
