Step 11:  Configure X.25 System-to-System Information 

NMMGR displays theDTC X.25 Card Configuration- Sys-to-Sys LUGs screen
(see Figure 3-10 ) if you press the [Go To SysLUG] key at the DTC X.25
Card Configuration screen or the DTC X.25 Card Configuration - Level 3 &
Miscellaneous screen.  On this screen, you specify information for X.25
system-to-system connections.  You can also reach this screen by typing
the following path at the Command line and pressing the [ENTER] key:

@DTS.DTC.SELECT.dtcname.X25CARDn.SYSLUG

          Figure 3-10.  DTC X.25 Card Configuration - Sys-to-Sys LUGs 

   1.  Verify that the cursor is in theX.25 link name field.  Enter the
       link name that will be used for X.25 iX System Access (X.25
       system-to-system connections) for this DTC/X.25 Network Access
       card.  This link name must be the same as the link name configured 
       on the X.25 Configuration screen during NS configuration (see
       chapter 6).

   2.  Move the cursor to theMaximum number of Switched Virtual  Circuit
       field.  Enter the maximum number of SVC connections that will be
       supported for this card.

   3.  Move the cursor to theSystem X.25 address field.  Enter the same
       X.25 address as entered in the X.25 card address field on the
       Level 3 and Miscellaneous screen unless your network application 
       requires the address used for X.25 system-to-system communications 
       to be different from that used for PAD communications.  If the
       addresses must be different, enter the X.25 address that the local
       system will use for system-to-system connections in this field.

       Note that with certain networks (such as Transpac, in France) the
       called address is removed from incoming call packets and the
       calling address is added to outgoing call packets by the network.
       For these networks, enter only the subaddress in this field, not
       the full X.25 address.

   4.  Move the cursor to the first Address field under 
       Enter remote X.25  addresses and security.  Enter the X.25 address
       of a system that will be able to establish a system-to-system
       connection with the HP 3000 Series 900 you are configuring.

   5.  Move the cursor to the Sec.  field next to the address you just
       entered.  Enter the security level for connections between the
       remote X.25 address and the system you are configuring.  Possible
       values are IN (accept calls from the address), OU (send calls to
       the address), and IO (accept calls from and send calls to the
       address).

   6.  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.

   7.  When you have entered all remote X.25 addresses and associated
       security, press the [Save Data] key to save the configuration.

   8.  Press the [Go To PAD] key to move to the DTC X.25 Card
       Configuration - Nailed PAD Connections 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              Displayonly.

       Card number           Displayonly.

       X.25 link name        The name of the linkthat will be used by the
                             system being configured for X.25
                             system-to-system connections.  Must be the
                             same as the link name entered during NS
                             configuration of X.25 iX System Access using
                             the NS subbranch of NMMGR. The link name can
                             be up to eight alphanumeric characters,
                             beginning with a letter.

       Maximum number of     The number of switched virtual
       Switched Virtual      circuits(SVCs) that will be allowed through
       Circuits              this DTC/X.25 Network Access card.  Up to 32
                             SVCs are allowed for cards mounted in a DTC
                             16, up to 256 SVCs are allowed for cards
                             mounted in a DTC 48 and up to 156 SVCs are
                             allowed for cards mounted in DTC 72MX.

                             The following factors must be considered in
                             determining how many SVCs to allow:

                                *   The total number of SVCs which an
                                    X.25 board can establish depends on
                                    the packet size configured in the
                                    X.25 level 3 configuration.  Upper
                                    limits for each DTC48 and DTC72MX
                                    card are:

                                       *   256 for packet sizes of 512 or
                                           less.

                                       *   150 for 1024 byte packets.

                                       *   100 for 2048 byte packets.

                                       *   54 for 4096 byte packets.

                                           Note that these limits are not
                                           affected by packet size
                                           negotiation.  That is, if you
                                           have configured a packet size
                                           of 4096, and a packet size of
                                           128 has been negotiated, you
                                           are still limited to the 54
                                           SVCs supported with 4096 byte
                                           packets.

                                *   If you are also configuring PAD
                                    connections on this card, remember
                                    that PAD connections use SVCs out of
                                    the pool of available SVCs.  You will
                                    need to balance your PAD
                                    support requirements with your
                                    system-to-system requirements to find
                                    the optimum configuration for your
                                    network.

                                *   The total number of SVCs available
                                    may also be limited by your PSN
                                    subscription.

       System X.25 address   This is the X.25 addressof the X.25 card, to
                             be used for system-to-system connections.
                             In most cases, this will be the same as the
                             address entered on the Level 3 &
                             Miscellaneous screen.  If, however, your
                             network application requires the
                             address used for X.25 system-to-system
                             communications to be different from the
                             address used for PAD connections, enter a
                             different address here.  For most
                             connections to public data networks, this
                             will be the DTC/X.25 Network Access card
                             address plus a unique subaddress for the
                             host system.

                             Note that with certain networks (such as
                             Transpac, in France) the called address is
                             removed from incoming call packets and the
                             calling address is added to outgoing call
                             packets by the network.  For these networks,
                             enter only the subaddress in this field, not
                             the full X.25 address.

       Address               The X.25 addresses of the remote systemsin
                             your X.25 network

       Sec.                  The securitylevel 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 12:  Configure Nailed PAD Connections 

NMMGR displays the DTC X.25 Card Configuration- Nailed PAD Connections
screen (see Figure 3-11 ) if you press the [Go To PAD] key from the
DTC X.25 Card Configuration screenor the DTC X.25 Card Configuration -
Sys-to-Sys LUGs screen.  On this screen, logical device (ldev) numbers,
profile names, device names, and remote X.25 addresses are permanently

                             If you enter Y, calls will only be accepted
                             from devices whose addresses you list on
                             this screen.  If you enter Y and do not list
                             any addresses, all calls will be rejected.

                             If you enter N, calls will only be rejected
                             from devices whose addresses you list on
                             this screen.  If you enter N and do not list
                             any addresses, all calls will be accepted.

                             If you do not update this screen (data flag
                             is N, a default PAD security will be
                             downloaded that allows all calls to be
                             accepted.

       below                 Allow access is Y or rejected for connection
                             if Allow access is N. Enter up to 32 remote
                             addresses per screen and up to 512 per
                             DTC/X.25 Network Access card.

                             You can use the letter X as a wildcard
                             character in place of any single digit.  All
                             systems with corresponding addresses will
                             have the same access rights.  The address
                             check is sensitive to the length of the
                             address.  To manage addresses, you may enter
                             pyramids of Xs where the base is the longest
                             expected address and the peak is the
                             shortest expected address.

                             For example to control access to all PAD
                             addresses of six, seven or eight digits
                             starting with 1234:

                                 Table 3-7.   

----------------------------
|                       |  |
| 1234XX                |  |
|                       |  |
----------------------------
|                       |  |
| 1234XXX               |  |
|                       |  |
----------------------------
|                       |  |
| 1234XXXX              |  |
|                       |  |
----------------------------

                             To control access to PADs with addresses of
                             seven digits starting with 6789:

                             6789XXX

Step 14:  Validate/Cross-Validate the Configuration File 

Validation ensures that no conflicts exist in the network
configurationfile 
(NMCONFIG.PUB.SYS) between the DTCs and other configuration parameters.
After NMMGR validates the network configuration file, it will
automatically cross-validate 
the file with the system I/O devices configured through the SYSGEN
utility.  This will take place only if the file opened at the start of
the NMMGR session is NMCONFIG.PUB.SYS and validation is successful.
Additionally, you must have System Manager (SM) capability or the cross-
validation will not occur.  The commands used for SYSGEN cross-validation
are in the file 
NMGRXVAL.PUB.SYS. If this file does not exist, NMMGR will create the file
for you before cross-validating.  You can edit this file as appropriate
for your environment.

Refer to the MPE/iX manual, System Startup, Configuration, and Shutdown 
Reference Manual (32650-90042), for information on SYSGEN.

   1.  To validate the DTS configuration in the configuration file, press
       the [Validate DTS/LINK] key at the Card Configuration screen.  You
       can also reach the Validate Configuration File screen by typing
       validate at the command line on top of any NMMGR screen and
       pressing [Enter].  (Note that the [Enter] key is not the carriage
       return key.)  While at the Validate screen press the [Validate 
       DTS/LINK] key to validate the DTS configuration.

       The DTS validationprocedure starts by displaying the following on
       the terminal:

                                 Table 3-8.   

---------------------------------------------------------------
|  |                                                          |
|  | -> Validation of DTS/LINK started.  <-                   |
|  |                                                          |
---------------------------------------------------------------
|  |                                                          |
|  | NOTE: In order for any TIO changes to take effect, you   |
|  | must reboot the system                                   |
|  |                                                          |
---------------------------------------------------------------
|  |                                                          |
|  | -> Validation of DTS/LINK finished.  <-                  |
|  |                                                          |
---------------------------------------------------------------

       If errors were encountered in the configuration file, the
       validation procedure will print out the total number of errors
       found.  Error messages will also be displayed explaining the
       problems found.  Refer to appendix A, "Error Messages," for more
       information about these error messages.

   2.  After validation of the network configuration file is complete,
       the following will appear on the screen as the file is
       cross-validated with the files created with SYSGEN (warning
       messages may vary):

                                 Table 3-9.

| NMMGR will now cross-validate the NMCONFIG file with SYSGEN.        |
|                                                                     |
