Editing an ITP Global Title Translation Table


You can use the Global Title Translation (GTT) Editor of the Cisco Mobile Wireless Transport Manager (MWTM) to configure GTT entries.

A global title is an application address, such as a toll-free telephone number, calling card number, or mobile subscriber identification number. GTT is the process by which the Signaling Connection Control Part (SCCP) translates a global title into the point code and subsystem number (SSN) of the destination service switching point (SSP), where higher-layer protocol processing occurs. GTT entries reside in GTT files, which are comma-separated value (CSV) text files with point codes written in hexadecimal notation.


Note The MWTM 6.1.7 supports GTT files with file format versions  3.1, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, or 4.6. You can load GTT files that use lower or higher file-format versions; but, fields or features that are unique to the lower or higher version are not visible and they disappear from the GTT file the next time you save the file. The file is saved as a version 3.1 file if the file is lower than version 3.1; or, as a version 4.6 file if the file is higher than version 4.6.


For more detailed information about GTT, including configuration procedures and scenarios, see the IP Transfer Point (ITP) feature module for Cisco IOS software release 12.2(25)SW4 or later.

Launching the GTT Editor

The MWTM provides you with a GTT Editor to edit GTT files. The GTT Editor runs as a separate application in the MWTM; so, it requires a separate login, just like the MWTM client.

To launch the GTT Editor, use one of these procedures:

Choose Tools > Global Title Translator Editor from the MWTM main menu.

Enter the mwtm gttclient command (see mwtm gttclient).

The Startup Options dialog box appears, which you use to load a specific GTT file or create a new GTT file.

The Startup Options dialog box provides options to load GTT data from:

Field or Button
Description

New File

Opens the Create New Table dialog box, which you use to create a new GTT file (see Creating a New GTT File). Create the new GTT file.

When you close the Startup Options dialog box by creating a new GTT file or loading an existing GTT file, the GTT Editor window appears with the Selectors and GTA tab clicked.

The GTT Editor window provides a set of tabs. Each tab contains a series of tables with GTT data. Some of the tables may be blank at first, while others contain rows of data.

In each table, you can edit the values in each row by typing over the current value or selecting a new value from a drop-down list box.

To reset a cell to its previous value, press Esc. (If you have edited more than one cell in a row, pressing Esc resets all cells in the row.) To save your changes, click outside the row. Once you save your changes, pressing Esc does not reset the cells in the row.

To add a row to a table, select the table, then choose Edit > Add from the GTT menu or Add from the right-click menu.

To delete one or more rows from a table, select the rows, then choose Edit > Delete from the GTT menu or Delete from the right-click menu (see Deleting Rows from a Table).

Checking the Semantics of a GTT File

The MWTM strongly recommends that you check the semantics of a GTT file against a specific ITP and validate this data in the GTT file:

ITP Point Code—For version 2.0 GTT files, the point code in the GTT file must differ from the primary, secondary, or capability point code of the ITP. If the file is the same, the MWTM generates an error. This restriction is not for GTT files of version 3.0 or later.

Route Table—The ITP route table must contain all point codes in the GTT file, other than the primary, secondary, or capability point code of the ITP. If the route table does not contain the point codes, the MWTM generates an error.

Route Status—All route entries for point codes in the GTT file, other than the ITP's primary, secondary, or capability point code, must be available. If they are not, the MWTM generates a warning.

GTA and Application Group—If an application server configures the GTA or the application group, then that application server must reside on the ITP. If it does not, the MWTM generates an error.

If the application server resides on the ITP, but it is not available, the MWTM generates a warning.

For example, ITP limits XUA configuration to instance 0. The MWTM semantic check verifies that XUA is not configured on any other instance.

To check the semantics of a GTT file, choose File > Semantic Check from the GTT menu. The Semantic Check GTT dialog box appears.

Field or Button
Description

ITP Name or IP Address

Name or IP address of the ITP against which to check the GTT file.

OK

Closes the Semantic Check GTT dialog box and opens the Progress dialog box, which shows the progress of the semantic check for the GTT file.

Enter the name or IP address of an ITP, and click OK. The MWTM closes the Semantic Check GTT dialog box and opens the Progress dialog box.

The Progress dialog box shows the progress of the semantic check for the GTT file and any messages that appear while checking the file.

After the check, click OK. The MWTM closes the Progress dialog box and returns to the Semantic Check GTT dialog box.

Cancel

Closes the Semantic Check GTT dialog box without checking the semantics of the GTT file.



Note You can also use the mwtm checkgtt command to semantics of a GTT file (see mwtm checkgtt).

Supporting Cross-Instance GTT Files

You use the ITP Multiple Instance feature to connect an ITP to more than one network at the same time, each with specific variant and network indicator values. The ITP treats each combination of variant and network indicator as a separate instance with its own local point code, routing table, and GTT file on the ITP. Instances in the same network must have the same network name.

In support of the Multiple Instance feature, ITP Instance Translation enables the conversion of packets between instances of any variants. Each instance is a separate domain with a defined variant, network indicator, ITP point code, optional capability point code, and optional secondary point code.

For more information about the ITP Multiple Instance and Instance Translation features, see the IP Transfer Point (ITP) feature module for Cisco IOS software release 12.2(4)MB10 or later.

GTT files that support the Multiple Instance and Instance Translation features are called cross-instance GTT files, because they contain application groups that reference point codes in other GTT files.

To handle cross-instance GTT files, the MWTM uses a server-wide network name mapping file, which maps the available network names to GTT variants and network indicators. The MWTM looks up network names in the file to parse point codes correctly, based on the user's cross-instance configuration.

When the MWTM discovers your network, it automatically creates and populates the network name-mapping file. Therefore, in most cases, you do not need to manually create the network name mapping file. For more information about running Discovery, see Managing and Deploying ITP Files.

In some cases, you might want to create the network name mapping file manually; for example, if you have not run Discovery yet, but you want to prepare for a future GTT configuration. Also, while you cannot change or delete entries that the MWTM automatically populated, you can add entries manually, and you can change or delete those manual entries.

To create the network name mapping file manually; or, to add, change, or delete manual entries, choose View > Network Name Configuration from the GTT menu. If you have implemented MWTM User-Based Access, this option is available to users with authentication level System Administrator (level 5). The Network Name Configuration dialog box appears.

The Network Name Configuration dialog box contains:

Network Name Configuration Dialog Box Menu

Network Name Configuration Dialog Box Table

Network Name Configuration Dialog Box Menu

The menu on the Network Name Configuration dialog box contains:

Menu Command
Description

File > Revert
(Ctrl-R)

Loads the most recent network name mapping file from the MWTM server.

If the MWTM discovers new entries for the network name mapping file while you are editing a GTT file (for example, if it adds a new network instance or it discovers a new network), the GTT Editor is unaware of the new entries and they are not visible in the Network Name Configuration dialog box. To see the new entries in the dialog box, choose File > Revert. (You can also restart the GTT Editor to automatically load the most recent network name mapping file from the MWTM server.)

File > Save
(Ctrl-S)

Saves the changes you make to the network name mapping file.

After you add, change, or delete entries and save the file, the MWTM uses the file the next time it discovers the network. However, if the MWTM discovers entries that conflict with manual entries in the file, the MWTM uses (and shows in the Network Name Configuration dialog box) the discovered entries, not the manual entries.

File > Print
(Ctrl-P)

Prints the contents of the network name mapping file.

File > Close
(Ctrl-W)

Closes the network name mapping file without saving any additions, changes, or deletions.

Edit > Add
(Alt-A)

Adds an entry to the network name mapping file.

Edit > Delete
(Delete)

Deletes the chosen entry from the network name mapping file.

Saving a GTT File

You use the MWTM to save a specific GTT file and change the list of GTT files.


Note The MWTM 6.1.7 supports GTT files with file format versions  3.1, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, or 4.6. You can load GTT files that use lower or higher file format versions; but, fields or features that are unique to the lower or higher version are not visible and they disappear from the GTT file the next time you save. The file is saved as a version 3.1 file if the file is lower than version 3.1 or as a version 4.6 file if the file is higher than version 4.6.


To save the changes make to a GTT file or change the list of GTT files, use one of these procedures. To save the changes you have made to the GTT file:

Without changing the name of the file, choose File > Save from the GTT menu.

With a new name, choose File > Save As from the GTT menu. The Save File dialog box: GTT File List appears.

Field or Button
Description

Type

Icon indicating whether the item in the table is a file or a folder.

Name

Name of the GTT file or folder.

Last Modified

Date and time the GTT file or folder was last modified.

Size (bytes)

Size of the GTT file or folder, in bytes.

Filename

Name by which you want to save the GTT file.

If you create a new GTT filename, you can use any letters, numbers, or characters in the name that your operating system allows. However, if you include any spaces in the new name, the MWTM converts those spaces to hyphens (-). For example, the MWTM saves file a b c as a-b-c.

Number of Files
(visible in bottom left corner)

Total number of GTT files and folders.

OK

Saves the GTT file or any changes you make to the list of files and closes the dialog box.

To save the GTT file with a new name, use one of these procedures. To save the file with:

A completely new name, enter the new name and click OK.

An existing name, overwriting an old GTT file, choose the name from the list and click OK.

The MWTM closes the Save File dialog box: GTT File List and the Progress dialog box appears.

The Progress dialog box shows the progress of the GTT file save, as well as any messages that appear while saving the file.

When the file is saved, click OK. The MWTM closes the Progress dialog box, saves the GTT file with the new name, and returns to the GTT Configuration window.

Note If another user modifies and saves the GTT file before you save your changes, the MWTM asks if you want to overwrite that user's changes. If you do, the other user's changes are overwritten and lost. If you choose not to, your changes are lost; unless you save the GTT file to a different filename.

Delete

Deletes the chosen file from the GTT file list. An informational message appears that contains the name and location of the deleted file.

Cancel

Closes the dialog box without saving the GTT file or any changes to the GTT file list.

Help

Shows online help for the dialog box.


When you are ready to exit the GTT Editor window, choose File > Exit from the GTT menu.

If you make any changes to the GTT file, the MWTM asks if you want to save the changes before leaving the window. Click:

Yes to save the changes.

The MWTM opens the Save File dialog box: GTT File List, which you use to save the GTT file with a new name, or overwrite an existing GTT file.

No to close the prompt window.

The MWTM closes the GTT Editor window without saving any changes to the GTT file.

By default, GTT files reside in the MWTM installation directory. If you installed the MWTM in:

The default directory, /opt, then the default directory is /opt/CSCOsgm/gtt.

A different directory, then the default directory resides in that directory.

To change the directory in which the MWTM stores GTT files, use the mwtm gttdir command (see mwtm gttdir).

Reverting to the Last Saved GTT File

To revert to the last saved version of the GTT file, choose File > Revert from the GTT menu. The MWTM shows the last saved version of the file.
