You must define characteristics for the X.25 PAD or system-to-system
connections you are configuring. Values need to be configured for
each DTC/X.25 Network Access card mounted in the DTCs for the system
you are configuring.
Whether you are configuring system-to-system, PAD connections,
or both, you will need to define values for levels 1, 2, and 3 of
the X.25 network. Most of these values are defined by your X.25
network subscription and you can transfer these values directly
to the DTC X.25 Card Configuration — Level 1 and 2 Worksheet
shown later in this Chapter, and the DTC X.25 Card Configuration
— Level 3 and Miscellaneous Worksheet shown later
in this Chapter.
If you are configuring system-to-system connections for an
X.25 network, you will need to define an X.25 link name, the maximum
number of SVCs, and remote X.25 addresses and security designations.
Once you have decided on your system-to-system configuration, you
can use the DTC X.25 Card Configuration — System-to-System
Worksheet shown later in this Chapter.
If you are configuring nailed PAD connections, you can use
the DTC X.25 Card Configuration — Nailed PAD Connections
Worksheet shown later in this Chapter.
If you are defining nailed PAD connections, you may also wish
to configure security. To do so, you list remote X.25 calling addresses
and specify whether you want all calls from the listed addresses
to be blocked, or all calls from the listed addresses (and only
the listed addresses) to be accepted. Once you have decided on the
security to be configured, use the DTC X.25 Card Configuration —
PAD Security Worksheet shown later in this Chapter, to list the
remote X.25 addresses.
