PAD Profiles and Access Password
When users attempt to establish a connection from a PAD, the PAD selection command
may specify a password and/or a profile number. The password will be needed if PAD
incoming security has been configured and the PAD access list is associated with the
calling address has had a password defined. The profile number may be specified to
override the PAD profile field configured for the PAD port.
The password is configured on the PAD access list screen in Step 7: Create and Modify
the PAD access lists. Refer to Chapter 3, “Configuring DTCs Step-by-Step,” for
information on configuring the password.
The PAD profile number is the number displayed by the
[Compute Byte]
function key. The
section DTC PAD Profiles contains a list of PAD profiles that are available. Entering a
profile number in the PAD selection command causes the DTC to use the particular PAD
profile when the connection is established.
The syntax to enter a password and/or profile number for the PAD selection command is:
@<X.25 address>,d[<password>][/<profile number>]
The following example supplies the password “secret” and causes the PAD profile 33 to
be used.
@ 1234567891234,dsecret/33
Forced Data Forwarding
When a connection is established to a PAD device, two of the characteristics that get set,
are the data forwarding parameters. The data forwarding parameters tell the PAD when
a packet must be sent to the PDN. The behavior of data forwarding is set with the fields
“Data forwarding parm #3 and #4” and “Forced data forwarding” on the PAD Terminal
Profile screen. The Forced data forwarding field also affects how the “Data forwarding
parm #3 and #4” field behaves. See the PAD Installation manual for further information
on the PAD parameters.
On the PAD, Parm #3 selects the set of characters that will signal the PAD to forward
data to the PDN. Parm #4 sets the idle timer in 1/20 second increments. The idle timer
will signal the PAD to forward data if the time between successive characters from the
terminal exceeds the idle timer value.
When “Forced data forwarding” bit is 0, the “Data forwarding parm #3 and #4” behave as
described in the Configuring Systems for Terminals, Printers, and Other Serial Devices
manual. The value specified in the field will be used when the connection to the is in:
0 0 x x x x x x No forced data forwarding
0 1 x x x x x x Forced data forwarding
