Removing a Global Title Translation

This procedure is used to remove a global title translation from the database using the dlt-gtt command.

The dlt-gtt command uses these parameters.

:gta – Global title start address – along with the egta parameter, identifies all valid global titles for the given translation type to translate to the given pc or ssn parameters. These are the non-SS7 addresses transmitted to the EAGLE for translation.

:egta – Global title end address – along with the gta parameter, identifies all valid global titles for the given translation type to translate to the given pc or ssn parameters. These are the non-SS7 addresses transmitted to the EAGLE for translation.

:type/typea/typei/typeis/typen/typens/typen24 – The translation type and network type of that translation type.
  • :type or :typea – an ANSI network
  • :typei – an ITU international network
  • :typeis – an ITU international spare network
  • :typen – a 14-bit ITU national network.
  • :typens – a 14-bit ITU national spare network.
  • :typen24 – a 24-bit ITU national network.

:ttn – The name of the global title translation type

If the translation type is defined as an alias, it cannot be used in the dlt-gtt command.

If the end of the global title address (egta) parameter is specified, the GTA and EGTA must have the same number of digits, but the EGTA must be larger than the GTA. The range, as specified by the start and end global title addresses, must be in the database for the specified translation type. Each range may be contained completely within a previously defined range, in which case splitting is performed. However, if the ranges overlap, splitting cannot occur, and the dlt-gtt command is rejected with this message.

The range of global title addresses, as specified by the start and end global title addresses, must be in the database for the specified translation type. The gta and egta parameter values must have the same number of digits, but the egta parameter value must be larger than the gta parameter value. Each range may be contained completely within a previously defined range, in which case splitting is performed. However, if the ranges overlap, splitting cannot occur, and the dlt-gtt command is rejected with this message.

E2401 Cmd Rej:GTA range overlaps a current range

Along with error message 2401, a list of the overlapped global title addresses is displayed as shown in the following example.

rlghncxa03w 07-05-24 08:29:15 GMT EAGLE5 37.0.0
The following GTA ranges overlap the input GTA range

8005554000              8005555999

DLT-GTT: MASP A - Command Aborted

For a range of global title addresses to be split, the new entry created by the split cannot increase the number of entries in the GTT table beyond the quantity shown in the rtrv-gtt output.

The length of the global title addresses specified by the gta or egta parameters must match the length of any existing global title addresses assigned to the specific translation type. The lengths are shown in the START GTA and END GTA fields of the rtrv-gtt command output, or in the NDGT field of the rtrv-tt command output. If the length of the global title address does not match one of the lengths already assigned to the translation type, the dlt-gtt command is rejected with this message.

E2960 Cmd Rej: The GTA length is not defined for the specified TT

When the VGTT feature is on, up to 10 different length global title addresses can be assigned to a translation type. If the Support for 16 GTT Lengths in VGTT feature is enabled and turned on, up to 16 different length global title addresses can be assigned to a translation type. The length of the global title address is only limited by the range of values for the gta and egta parameters of the ent-gtt and chg-gtt commands, one to 21 digits, and by the global title addresses already assigned to the translation type. The ndgt parameter of the ent-tt command has no effect on the length of the global title address and cannot be used. If the ndgt parameter is specified with the ent-tt command and the VGTT feature is on, the ent-tt command is rejected with this message.

E4011 Cmd Rej: NDGT parameter is invalid for VGTT

If the Variable-length Global Title Translation Feature (VGTT) is on, or the Support for 16 GTT Lengths in VGTT feature is enabled and turned on, the NDGT field of the rtrv-tt command shows the different lengths of global title addresses assigned to a translation type, as shown in the following example.

In this example of the rtrv-tt command output, the ANSI translation type 1 contains three different length global title addresses; global title addresses containing six digits, 12 digits, and 15 digits.

When the VGTT feature is on, or the Support for 16 GTT Lengths in VGTT feature is enabled and turned on, and the last global title address of a particular length is deleted for the specified translation type, then that length is no longer supported. That length is not displayed in the NDGT field of the rtrv-tt command output. For example, if the last 6-digit global title address is deleted from ANSI translation type 1 (from the previous example), the NDGT field of the rtrv-tt command shows only the numbers 12 and 15 in the NDGT field indicating that ANSI translation type 1 contains only 12- and 15-digit global title addresses.

Canceling the RTRV-GTT Command

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

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

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

  • Enter the canc-cmd:trm=<xx>, where <xx> is the terminal where the rtrv-gtt command was entered, from another terminal other that the terminal where the rtrv-gtt 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. Verify that the GTT feature is on, by entering the rtrv-feat command. If the GTT feature is on, the GTT field should be set to on.

    Note:

    The rtrv-feat command output contains other fields that are not used by this procedure. If you wish to see all the fields displayed by the rtrv-feat command, refer to the rtrv-feat command description in Commands User's Guide..

    If the GTT feature is off, this procedure cannot be performed.

    If the GTT feature is on, continue the procedure with 2.

  2. Display the translation types in the database using the rtrv-tt command.

    This is an example of the possible output.

    If the EGTT feature is off, shown in 1, continue the procedure with 5.

    If the EGTT feature is on, continue the procedure with 3.

  3. Display the GTT set that contains the TTN value that is assigned to the GTT entry that is being removed. Enter the rtrv-gttset command with the gttsn parameter. The value of the gttsn parameter is the TTN value associated with the translation type, shown in 2, that is assigned to the GTT entry that is being removed.

    For this example, enter this command.

    rtrv-gttset:gttsn=scp2

    This is an example of the possible output.

    If the NETDOM value of the GTT set is CROSS, the GTT entry cannot be removed with this procedure. Perform the Removing Global Title Address Information procedure to remove the GTT entry.

    If the NETDOM value is ANSI or ITU, continue the procedure with 4.

  4. Display the GTA entries that reference the TTN value that is assigned to the GTT entry that is being removed. Enter the rtrv-gta command with the gttsn parameter. The value of the gttsn parameter is the gttsn value that was specified in 3.

    For this example, enter this command.
