3. Repeat steps 4 and 5 for each remote system that will be able to establish a
system-to-system connection with the HP 3000 Series 900 you are configuring. If you
need to enter more than eight remote system addresses, press the
[Save Data]
key to
save the data on this screen, then use the
[Next Page]
key to move to a new data entry
screen to configure additional addresses.
4. When you have entered all remote X.25 addresses and associated security, press the
[Save Data]
key to save the configuration.
5. Press the
[Go To SysSwth]
key to move to the DTC X.25 Card Configuration
—Sys-to-Sys Switching Table screen.
Fields This screen lets you configure X.25 system-to-system local user group (LUG)
information for the DTC/X.25 Network Access card being configured.
DTC name Display only.
Card number Display only.
Address The X.25 addresses of the remote systems in your X.25 network up
to 15 digits long.
You can use the letter “X” as a wildcard character in place of any
single-digit. Note that “X” represents one digit only, and the
address checking is sensitive to the length of the address. Thus, for
example, x=0 to 9; xx=00 to 99, but not 0 to 9. To manage
addresses, you must construct pyramids, where the base is the
maximum expected address length, and the peak is the minimum
expected address length.
For example, to allow IN/OUT access to all six, seven, and eight
digit X.25 address that start 1234, you would enter the following
values:
1234XX IO
1234XXX IO
1234XXXX IO
Addresses without wildcards take precedence over addresses with
wildcards. So in the following example 123401 can only call in,
even though all address corresponding to 1234XX are listed as
having both IN and OUT access.
1234XX IO
123401 IN
Sec. The security level associated with each remote X.25 address. To
accept only incoming calls for call setup, enter IN in the security
field beside the address. To allow only outgoing calls for call setup,
enter OU. To allow both incoming and outgoing calls for call setup,
enter IO.
Step 15: Configure X.25 System-to-System Switching
When you press the
[Go To SysSwth]
key at the DTC X.25 Card Configuration screen or
the DTC X.25 Card Configuration -- Sys-to-Sys LUGs screen, NMMGR displays the DTC
X.25 Card Configuration -- Sys-to-Sys Switching Table screen (DTC X.25 Card
Configuration Sys-to-Sys Switching Table Screen). On this screen, you specify
