Changing Global Title Modification Information

This procedure is used to change the attributes of global title (GT) modification information in the database. The GT modification information is changed using the chg-gtmod command with these parameters.

:gtmodid – The current name of the GT modification identifier

:ngtmodid – The new name of the GT modification identifier

:cgpassn – The subsystem number in the calling party address

:ntt – The new translation type

:nnp – The new numbering plan

:nnai – The new nature of address indicator

:npdd – The number of digits to be deleted from the beginning of the Global Title Address digits (the prefix digits)

:npds – The digits that are being substituted for the prefix digits

:nsdd – The number of digits to be deleted from the end of the Global Title Address digits (the suffix digits)

:nsds – The digits that are being substituted for the suffix digits

:ngti – The new GT indicator value

on=gt0fill - if the last value of the global title address is zero (0), it is treated or as a filler during the GT modification process.

off=gt0fill - if the last value of the global title address is zero (0), it is treated as a valid digit during the GT modification process.

precd - specifies whether the prefix (npds/npdd parameter values) or suffix (nsds/nsdd parameter values) takes precedence while modifying the received Global Title Address.

The values for these parameters and the rules for using these parameters are shown in Table 2-65.

The nnp, nnai, npdd, npds, nsdd, and nsds parameters are used by the Advanced GT Modification feature to modify the numbering plan, nature of address indicator, and the prefix digits, the suffix digits, or both the prefix and suffix digits in the called party address portion of outbound MSUs in addition to the translation type when the MSU requires further global title translation and the translation type is to be replaced. Refer to the Advanced GT Modification Feature section for more information about the Advanced GT Modification feature.

Being able to change the numbering plan, nature of address indicator, and either the prefix or suffix digits in the called party address portion of outbound MSUs makes the MSU more compatible with the network that the MSU is being sent to and to ensure that the MSU is routed correctly. These changes are made after the global title translation process, but before the MSU is routed to its destination.

To specify a value of 2 or 4 for the ngti parameter, the ANSI/ITU SCCP Conversion feature must be enabled. Verify the status of the ANSI/ITU SCCP Conversion feature with the rtrv-ctrl-feat command. Refer to the ANSI/ITU SCCP Conversion Feature section for more information about the ANSI/ITU SCCP Conversion feature. If the ANSI/ITU SCCP Conversion feature is not enabled, perform the Activating the ANSI/ITU SCCP Conversion Feature procedure to enable the ANSI/ITU SCCP Conversion feature.

The values specified for the npds and nsds parameters can be decimal digits (0-9) or hexadecimal digits (0-9, a-f, A-F). Hexadecimal digits can be specified only if the Hex Digit Support for GTT feature is enabled. Verify the status of the Hex Digit Support for GTT feature with the rtrv-ctrl-feat command. Refer to the Hex Digit Support for GTT section for more information about the Hex Digit Support for GTT feature. If the Hex Digit Support for GTT feature is not enabled, perform the Activating the Hex Digit Support for GTT Feature procedure to enable the Hex Digit Support for GTT feature.

1. Display the GT modification information in the database using the rtrv-gtmod command.

   This is an example of the possible output.

   GTMOD table is (5 of 100000) 1% full.

   If entries are not displayed, this procedure cannot be performed.

   If entries are displayed, continue the procedure by performing one of these steps.

   • If only the gtmodid or ntt parameter values will be changed, continue the procedure with 6.
   • If the values for other parameters besides the gtmodid and ntt parameter values will be changed, continue the procedure by performing one of these steps.
     • If any of the entries shown in the rtrv-gtmod output contains values for parameters other than the gtmodid and ntt parameters, continue the procedure with 3.
     • If all of the entries shown in the rtrv-gtmod output contains only values for the gtmodid and ntt parameters, continue the procedure with 2.
2. One of the Advanced GT Modification features must be enabled to change the values of the parameters other than the gtmodid and ntt parameters. Enter the rtrv-ctrl-feat command to verify if any of the Advanced GT Modification features are enabled.
   If any of the Advanced GT Modification features are enabled, one of these entries is shown in the rtrv-ctrl-feat output.

   If none of the Advanced GT Modification features are enabled, perform the Activating the Advanced GT Modification Feature procedure to enable any of the Advanced GT Modification features.

3. For some parameters and values of the chg-gtmod command to be specified, these conditions must be present.

   To specify hexadecimal digits for the npds and nsds parameters, the Hex Digit Support for GTT feature must be enabled. If hexadecimal digits are shown in the rtrv-gtmod output, the Hex Digit Support for GTT feature is enabled.

   To specify the ngti parameter value 2 or 4, or the on=gt0fill parameter, the ANSI/ITU SCCP Conversion feature must be enabled. If values 2 or 4 for the ngti parameter are shown in the rtrv-gtmod output, or the GT0FILL value ON is shown in the rtrv-gtmod output, the ANSI/ITU SCCP Conversion feature is enabled.

   To specify the value none for the ngti parameter, the GT0FILL value must be OFF.

   If the gt0fill value will be changed to on, the ngti value must be 2 or 4.

   If the ngti value will be changed to 4, the nnp and nnai parameters must be specified and their values cannot be none. The network type of the point code in the entity that references the GT modification identifier that is being changed must be ITU.

   If the ngti value will be changed from 4 to 2, the nnp and nnai parameter values will be removed from the GT modification identifier.

   If the ngti value is 2 when this procedure is finished, the nnp and nnai parameters cannot be specified.

   If the ngti parameter will have no value when this procedure is finished (ngti=none), the nnp and nnai parameters can be specified.

   Continue the procedure with 6 if any of these conditions are present.

   • The Hex Digit Support for GTT and ANSI/ITU SCCP Conversion features are enabled.
   • If hexadecimal digits will not be specified for the npds or nsds parameters, and the ngti or the on=gt0fill parameters will not be specified with the chg-gtmod command.

   If hexadecimal digits will be specified for the npds or nsds parameters and hexadecimal digits are not shown in the rtrv-gtmod output, continue the procedure with 4.

   If the ngti parameter values 2 or 4, or the on=gt0fill parameter will be specified with the chg-gtmod command, and values 2 or 4 for the ngti parameter are not shown in the rtrv-gtmod output or the GT0FILL value ON is not shown in the rtrv-gtmod output, continue the procedure with 5.

   After these steps have been performed, as needed, continue the procedure with 6.

4. Verify the status of the Hex Digit Support for GTT feature by entering this command.

   rtrv-ctrl-feat:partnum=893018501

   Mandatory Parameter
   :gtmodid=<the current GTMOD ID shown in the rtrv-gtmod output>
   Optional Parameters
   :cgpassn=<2 – 255, or none>	:nsdd=<1 – 21, or none>
   :ngti=<2, 4, or none>	:nsds=<1 – 21 decimal digits, 1 – 21 hexadecimal digits, or none>
   :nnai=<0 – 127, or none>	:ntt=<0 – 255, or none>
   :nnp=<0 – 15, or none>	:off=gt0fill – this parameter cannot be specified if the on=gt0fill parameter is specified.
   :npdd=<1 – 21, or none>	:on=gt0fill – this parameter cannot be specified if the off=gt0fill parameter is specified.
   :npds=<1 – 21 decimal digits, 1 – 21 hexadecimal digits, or none>	:precd=<pfx or sfx> pfx - the prefix digits (npds/npdd parameter values) of the received Global Title Address. sfx - the suffix digits (nsds/nsdd parameter values) of the received Global Title Address.
   :ngtmodid=<the new GTMOD ID consisting of 1 alphabetic character with up to 8 alphanumeric characters>
   Notes: At least one optional parameter must be specified. If either the npdd/npds or nsdd/nsds parameter combinations are specified, the precd parameter cannot be specified. If the npdd/npds and nsdd/nsds parameter combinations are specified, the precd parameter must be specified. If the precd parameter is specified, the npdd/npds and nsdd/nsds parameter combinations must be specified. The combined length of npds and nsds parameter values cannot exceed 21 digits. The ngtmodid parameter changes the references from the current gtmodid value to the new gtmodid value in the entities that reference the current gtmodid value. See 3 for other requirements for using these parameters.

   For this example, enter this command.

   chg-gtmod:gtmodid=modid6:ngti=2:gt0fill=off:precd=pfx:npdd=4:npds=2345 :nsdd=4:nsds=12ae:ngtmodid=modid7

   When the command has successfully completed, this message appears.

   GTMOD table is (5 of 100000) 1% full.
   
   CHG-GTMOD: MASP A - COMPLTD

7. Verify the changes by entering the rtrv-gtmod command with the gtmodid parameter. The gtmodid parameter value is the gtmodid parameter value, if the GT modification identifier was not changed, or the ngtmodid parameter value, if the GT modification identifier was changed, that was specified in 6. For this example, enter this command.

   rtrv-gtmod:gtmodid=modid7

   This is an example of the possible output.
