Adding a Mapped SS7 Message Translation Type

This procedure is used to add a mapped SS7 message translation type to the database. The mapped translation type is added to the database using the ent-ttmap command and is assigned to an ANSI SS7 linkset.

The ent-ttmap command uses these parameters.

:lsn – the name of the linkset.

:io – is translation type mapping to be performed on SS7 messages received in the linkset (incoming linkset) or on SS7 messages sent on the linkset (outgoing linkset).

:ett – the translation type contained in the SS7 message before that translation type is mapped.

:mtt – the translation type that the value of the ett parameter is mapped to.

The examples in this procedure are used to map the SS7 message translation type 250 to the translation type 001 for any incoming messages on linkset lsn01.

Canceling the RTRV-LS Command

Because the rtrv-ls command used in this procedure can output information for a long period of time, the rtrv-ls command can be canceled and the output to the terminal stopped. There are three ways that the rtrv-ls command can be canceled.

• Press the F9 function key on the keyboard at the terminal where the rtrv-ls command was entered.

• Enter the canc-cmd without the trm parameter at the terminal where the rtrv-ls command was entered.

• Enter the canc-cmd:trm=<xx>, where <xx> is the terminal where the rtrv-ls command was entered, from another terminal other that the terminal where the rtrv-ls command was entered. To enter the canc-cmd:trm=<xx> command, the terminal must allow Security Administration commands to be entered from it and the user must be allowed to enter Security Administration commands. The terminal’s permissions can be verified with the rtrv-secu-trm command. The user’s permissions can be verified with the rtrv-user or rtrv-secu-user commands.

For more information about the canc-cmd command, go to Commands User's Guide.

1. Display the mapped translation types in the database using the rtrv-ttmap command.

   This is an example of the possible output.

   If the required linkset is not in the database, perform the “Adding an SS7 Linkset” procedure in Database Administration - SS7 User's Guide and add the linkset..

3. Add the mapped translation type to the database using the ent-ttmap command. For this example, enter this command.

   ent-ttmap:lsn=lsn01:io=i:ett=001:mtt=250

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

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.
