Configuring the ITU Linkset NI Mapping Options

This procedure is used to configure the network indicator (NI) mapping options for an ITU-I or ITU-N linkset. These options are configured with the chg-lsopts command and these parameters.

:lsn - The name of the ITU-I or ITU-N linkset.

:icnimap - This parameter specifies the type of network indicator (NI) mapping for incoming MSUs on the linkset. The NI value in the incoming MSU is changed to the value specified by the icnimap parameter before processing the message. The values for this parameter are: itui2ituis, ituis2itui, itun2ituns, ituns2itun, or none.
  • itui2ituis - Map the ITU international network indicator value to the ITU international spare network indicator value
  • ituis2itui - Map the ITU international spare network indicator value to the ITU international network indicator value
  • itun2ituns - Map the ITU national network indicator value to the ITU national spare network indicator value
  • ituns2itun - Map the ITU national spare network indicator value to the ITU national network indicator value
  • none - network indicator mapping is not performed on the specified linkset.
The value of the icnimap parameter for the linkset is not changed if the icnimap parameter is not specified with the chg-lsopts command. The system default value for the icnimap parameter is none.
:ognimap - This parameter specifies the type of network indicator (NI) mapping for outgoing MSUs on the linkset. The NI value in the processed MSU is changed to the value specified by the ognimap parameter for that linkset before routing the message to its intended destination. The values for this parameter are: itui2ituis, ituis2itui, itun2ituns, ituns2itun, or none.
  • itui2ituis - Map the ITU international network indicator value to the ITU international spare network indicator value
  • ituis2itui - Map the ITU international spare network indicator value to the ITU international network indicator value
  • itun2ituns - Map the ITU national network indicator value to the ITU national spare network indicator value
  • ituns2itun - Map the ITU national spare network indicator value to the ITU national network indicator value
  • none - network indicator mapping is not performed on the specified linkset.
The value of the ognimap parameter for the linkset is not changed if the ognimap parameter is not specified with the chg-lsopts command. The system default value for the ognimap parameter is none.
To specify the icnimap and ognimap parameters, the ITU National and International Spare Point Code Support feature must be enabled. Refer to the Activating the ITU National and International Spare Point Code Support Feature procedure for information about enabling the ITU National and International Spare Point Code Support feature. Values for the icnimap and ognimap parameters other than none can be specified only for linksets that have ITU-I or 14-bit ITU-N adjacent point codes. If either the icnimap or ognimap parameters are specified for the chg-lsopts command, both parameters must be specified for the chg-lsopts command. The network indicator mapping value for incoming messages on the linkset must be compatible with the network indicator mapping value for the outgoing messages on the linkset. For example, if the icnimap=itui2ituis parameter is specified for the linkset, the ognimap=ituis2itui parameter must be specified for the linkset. Table 3-30 shows the relationship between the icnimap and ognimap parameter values.

Table 3-30 Network Indicator Mapping Rules

ICNIMAP Parameter Value OGNIMAP Parameter Value
ITUI2ITUIS ITUIS2ITUI
ITUIS2ITUI ITUI2ITUIS
ITUN2ITUNS ITUNS2ITUN
ITUNS2ITUN ITUN2ITUNS
NONE NONE

The values of the icnimap and ognimap parameters are shown in the ICNIMAP and OGNIMAP columns of the rtrv-ls output. The ICNIMAP and OGNIMAP columns are shown only if the linkset name (lsn parameter) is specified with the rtrv-ls command, the ITU National and International Spare Point Code Support feature is enabled, and if the adjacent point code of the linkset is either an ITU-I or ITU-N point code.

  1. Display the linksets that are provisioned in the database by entering the rtrv-ls command.

    The following is an example of the possible output.

    This procedure can be performed only on ITU-I or ITU-N linksets. An ITU-I linkset is a linkset whose adjacent point code is shown in the APCI column of the rtrv-ls output. An ITU-N linkset is a linkset whose adjacent point code is shown in the APCN column of the rtrv-ls output. If no ITU-I or ITU-N linksets are shown in this step, this procedure cannot be performed.

    If ITU-I or ITU-N linksets are shown in this step, continue the procedure with 2.

  2. Display one of the ITU-I or ITU-N linksets shown in 1 by entering the rtrv-ls command with the name of one of the ITU-I or ITU-N linksets shown in 1. For this example, enter this command.

    rtrv-ls:lsn=lsn5

    The following is an example of the possible output.

    The ITU NI mapping options are shown in the ICNIMAP and OGNIMAP columns in the rtrv-ls output. The ITU National and International Spare Point Support feature must be enabled for these columns to appear in the rtrv-ls output.
    • If the ICNIMAP and OGNIMAP columns are shown in the rtrv-ls output, continue the procedure with 3.
    • If the ICNIMAP and OGNIMAP columns are not shown in the rtrv-ls output, the ITU National and International Spare Point Code Support feature must be enabled. Perform the Activating the ITU National and International Spare Point Code Support Feature procedure to enable the ITU National and International Spare Point Code Support feature. After the ITU National and International Spare Point Code Support feature has been enabled, continue the procedure with 3.
  3. Configure the ITU network indicator mapping options for the linkset displayed in 2 by entering the chg-lsopts command.

    For this example, enter this command.

    chg-lsopts:lsn=lsn5:icnimap=itun2ituns:ognimap=ituns2itun

    Note:

    The network indicator mapping value for incoming messages on the linkset must be compatible with the network indicator mapping value for the outgoing messages on the linkset. For example, if the icnimap=itui2ituis parameter is specified for the linkset, the ognimap=ituis2itui parameter must be specified for the linkset. Table 3-30 shows the relationship between the icnimap and ognimap parameter values. The icnimap and ognimap parameter values entered in this step must be entered according to the relationships shown in Table 3-30.

    When this command has successfully completed, the following message should appear.

    Link set table is (13 of 1024) 1% full.
    CHG-LSOPTS: MASP A - COMPLTD
    
  4. Verify the changes by entering the rtrv-ls command with the name of the linkset specified in 3. For this example, enter this command.

    rtrv-ls:lsn=lsn5

    The following is an example of the possible output.

  5. Back up the new changes using the chg-db:action=backup:dest=fixed command. These messages should appear, the active Maintenance and Administration Subsystem Processor (MASP) appears first.
    BACKUP (FIXED) : MASP A - Backup starts on active MASP.
    BACKUP (FIXED) : MASP A - Backup on active MASP to fixed disk complete.
    BACKUP (FIXED) : MASP A - Backup starts on standby MASP.
    BACKUP (FIXED) : MASP A - Backup on standby MASP to fixed disk complete.
