IP Stream port:
When IP Stream mode is on this parameter defines the port number to use.
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.
Strip Trailing Spaces:
When this parameter is turned on any spaces received at the end of a sequence of data from
the network will be removed before being relayed to the PAD port.
Leased line mode:
When this parameter is set to “On”, it causes the PAD to always attempt to be connected using
the Auto macro setting as the call command.
LCN:
The unit supports up to eight logical X.25 channels. In practice, the operational limit is deter-
mined by the particular service to which you subscribe (usually 4).
Each logical channel must be assigned a valid Logical Channel Number (LCN). The LCN parame-
ter is the value of the first LCN that will be assigned for outgoing X.25 CALLs. The default is
1027.
For incoming calls, the unit accepts the LCN specified by the caller.
LCN direction:
This parameter determines whether the LCN used for outgoing X.25 calls is incremented or
decre mented from the starting value when multiple X.25 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 incre-
mented from the start value.
ENQ on connect:
When this parameter is set to “On” the PAD will send an ENQ character on the ASY link when
an outgoing call has been answered.
NUI/NUA selection:
If both an NUI and an NUA are included in the call string, this parameter allows the unit to fil-
ter one of these out of the X.25 call request. This can be extremely useful in backup scenarios.
Consider the following example; the unit is configured to do online authorisations via the ISDN
D channel and to fall back to B-channel (if the D-channel host did not respond for 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).
PAD profile #:
The PAD profile # allows you to select the PAD profile to use for this PAD instance. There are
four pre-defined profiles numbered “50”, “51”, “90” and “91”. In addition to the pre-defined pro-
files you can also create up to four user-defined profiles numbered “1”, “2”, “3” and “4”.
To assign a particular profile to the PAD select the appropriate number from the list.
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.
Restart delay (ms): When the Restarts parameter is “On” the Restart Delay value determines
the length of time in mil liseconds that the unit will wait before issuing a Restart packet. The
default value is 2000 giving a delay of 2 seconds.
