4 Global Title Translation (GTT) Configuration
Chapter 4, Global Title Translation (GTT) Configuration, describes the procedures used to administer global title translation data.
4.1 Provisioning a Mated Application
This procedure is used to add a dominant mated application to the database.
The only parameters that can be specified with this procedure are the primary point code, primary subsystem number, mate point code, and mate subsystem number. The EAGLE relative cost parameters cannot be specified in this procedure. When the mated application is added to the database with this procedure, the relative cost value for the primary point code and subsystem is defaulted to 10. The relative cost value for the mate point code and subsystem is defaulted to 50. This creates a dominant mated application with only two entries.
This procedure uses the EAGLE commands rtrv-map
, rtrv-ctrl-feat
, rtrv-dstn
, and chg-db
. For more information on provisioning mated applications, refer to one of the “Provisioning a Mated Application” procedures in Database Administration - GTT User's Guide.
If you wish to use the pci, pcn, pcn24, mpci, mpcn, mpcn24, srm, grp, mrc, rc, materc, or mapset, wt, mwt, thr, mrnset, or mrnpc parameters of the EAGLE’s ent-map
command, the subsystem assigned to the mated application is the LNP, INP, V-Flex, ATINPQ, AIQ, or EIR subsystem, or you wish to create another type of MAP group or MAP set, perform one of the “Provisioning a Mated Application” procedures in Database Administration - GTT User's Guide using the SEAS FLOW-THRU
command with the EAGLE commands.
Mated application groups in the EAGLE database can contain up to 32 entries, the primary point code, and up to 31 mate point codes. SEAS allows the user to configure only two entries for each MAP group. To add more entries to the MAP group, up to 30, after performing this procedure, perform one of the “Provisioning a Mated Application” procedures in Database Administration - GTT User's Guide using the SEAS FLOW-THRU
command with the EAGLE commands. The rc
and materc
parameters must be specified with the EAGLE’s chg-map
command. The maximum number of mated application entries that can be provisioned in the EAGLE is 1024, 2000, or 3000, depending on the quantity that is enabled.
If the Flexible GTT Load Sharing feature is enabled, shown by the MAPSET
field in the EAGLE rtrv-map
output, by default the mated application is assigned to the default MAP set. To assign a mated application to a MAP set other than the default MAP set, perform one of the “Provisioning a Mated Application” procedures in Database Administration - GTT User's Guide using the SEAS FLOW-THRU
command with the EAGLE commands.
A proxy point code cannot be assigned to any point code that will be assigned to a mated application.
Figure 4-1 Provisioning a Mated Application
4.2 Removing a Mated Application
This procedure is used to remove a mated application from the database. This procedure uses the EAGLE commands rtrv-feat
, rtrv-ctrl-feat
, rtrv-ss-appl
, dlt-map
, and chg-db
. For more information on this procedure, see “Removing a Mated Application” in Database Administration - GTT User's Guide.
If you wish to use the pci
, pcn
, pcn24
, all
, mapset
, or mrnset
parameters of the EAGLE’s dlt-map
command, perform the “Removing a Mated Application” procedure in Database Administration - GTT User's Guide using the SEAS FLOW-THRU
command with the EAGLE commands.
If the Flexible GTT Load Sharing feature is enabled, only entries in the default MAP set are displayed from the SEAS terminal. Performing this procedure removes only mated application entries in the default MAP set. To remove entries from a MAP set other than the default MAP set, perform the “Removing a Mated Application” procedure in Database Administration - GTT User's Guide using the SEAS FLOW-THRU
command with the EAGLE commands.
The output from the EAGLE command rtrv-ctrl-feat
shows whether or not the Flexible GTT Load Sharing feature is enabled.
The EAGLE's point code and subsystem can be assigned to the mated application. If the mated application contains EAGLE's point code and the subsystem shown in Table 4-1, perform the “Removing a Mated Application” procedure in Database Administration - GTT User's Guide using the SEAS FLOW-THRU
command with the EAGLE commands.

4.3 Changing a Mated Application
This procedure is used to change an existing mated application in the database. The only parameters that can be specified in this procedure are the primary point code, primary subsystem number, mate point code, and mate subsystem number. The EAGLE relative cost parameters cannot be specified in this procedure. When the mated application is added to the database with this procedure, the relative cost value for the primary point code and subsystem is defaulted to 10. The relative cost value for the mate point code and subsystem is defaulted to 50. This creates a dominant mated application with two entries.
If you wish to use the pci, pcn, pcn24, mpci, mpcn, mpcn24, srm, grp, mrc, rc, materc, sso, mapset, eswt, wt, mwt, grpwt, thr, mrnset, or mrnpc parameters of the EAGLE’s chg-map
command, or if the subsystem assigned to the mated application is the LNP, EIR, V-Flex, ATINPQ, AIQ, or INP subsystem, perform any of the procedures from Database Administration - GTT User's Guide that are shown in Table 4-2 using the SEAS FLOW-THRU
command with the EAGLE commands.

If you plan to change the existing MAP group to another type of MAP group, perform the Changing the Mated Application Type procedure in Database Administration - GTT User's Guide using the SEAS FLOW-THRU
command with the EAGLE commands.
The mate point code cannot be changed to the EAGLE’s true point code.
This procedure uses the EAGLE commands chg-db
and rtrv-dstn
. For more information about changing a mated application, refer to the procedures from Database Administration - GTT User's Guide that are shown in Table 4-2on this procedure, see “Changing a Mated Application” in Database Administration - GTT User's Guide.
No new entries can be added to a mated application group with this procedure. Mated application groups in the EAGLE database can contain up to 32 eight entries, the primary point code, and up to 31 seven mate point codes. SEAS allows the user to configure only two entries for each MAP group. To add more entries to the MAP group, up to 30 six, perform one of the “Provisioning a Mated Application” procedures in Database Administration - GTT User's Guide using the SEAS FLOW-THRU
command with the EAGLE commands. The rc
and materc
parameters must be specified with the EAGLE’s chg-map
command. The maximum number of mated application entries that can be provisioned in the EAGLE is 1024, 2000, or 3000, depending on the quantity that is enabled.
If the Flexible GTT Load Sharing feature is enabled, only entries in the default MAP set are displayed from the SEAS terminal. Performing this procedure changes only mated application entries in the default MAP set. To change entries in a MAP set other than the default MAP set, perform any of the procedures from Database Administration - GTT User's Guide that are shown in Table 4-2 using the SEAS FLOW-THRU
command with the EAGLE commands
The output from the EAGLE command rtrv-ctrl-feat
shows whether or not the Flexible GTT Load Sharing feature is enabled.
A proxy point code cannot be assigned to any point code that will be assigned to a mated application.

4.4 Adding a Global Title Translation
This procedure is used to add a global title translation to the database. This procedure uses the EAGLE commands rtrv-ctrl-feat
, rtrv-feat
, chg-feat
, rtrv-card
, rtrv-tt
, rtrv-gtt
, rtrv-dstn
, rtrv-gttsel
, and chg-db
. For more information on this procedure, see “Adding a Global Title Translation” in Database Administration - GTT User's Guide.
The following parameters of the EAGLE’s ent-gtt
command are not supported by SEAS: typei, typeis, typen, typens, typen24, pci, pcn, pcn24, ttn, xlat, gtmodid , force, mrnset, mapset, loopset, or cggtmod.
SEAS does not support hexadecimal digits as the value of the global title address parameter. If you wish to use any of these parameters, or use hexadecimal digits as the value for the global title address parameter, perform the “Adding a Global Title Translation” procedure in Database Administration - GTT User's Guide using the SEASFLOW-THRU
command with the EAGLE commands.
If the Flexible GTT Load Sharing feature is enabled, shown by the MRNSET
field in the EAGLErtrv-gtt
output, and the routing indicator of the global title translation is G
(the EAGLE value GT
), by default, the global title translation is assigned to the default MRN set. To assign the global title translation to an MRN set other than the default MRN set, perform the “Adding a Global Title Translation” procedure in Database Administration - GTT User's Guide using the SEAS FLOW-THRU
command with the EAGLE commands.
If the Flexible GTT Load Sharing feature is enabled, shown by the MAPSET
field in the EAGLErtrv-gtt
output, and the routing indicator of the global title translation is D
(the EAGLE value SSN
), by default, the global title translation is assigned to the default MAP set. To assign the global title translation to a MAP set other than the default MAP set, perform the “Adding a Global Title Translation” procedure in Database Administration - GTT User's Guide using the SEAS FLOW-THRU
command with the EAGLE commands.
The EAGLE XLAT
parameter does not have a SEAS equivalent. When global title translations are configured at the SEAS interface, the values for the SEAS parameters RI
, DPC
, and SSN
, all mandatory parameters for the SEAS ADD-GTT
and CHG-GTT
commands, are converted to the EAGLE parameters and values shown in Table 4-3.
The RC
parameter of the SEAS ADD-GTT
command is not supported by the EAGLE. While the RC
parameter must be specified with the SEAS ADD-GTT
command, the RC
parameter is discarded when the SEASADD-GTT
command is processed by the EAGLE.
A proxy point code cannot be assigned to any point code that will be assigned to a global title translation.

command are not supported by SEAS: typei, typeis, typen, typens, typen24, pci, pcn, pcn24, ttn, xlat, gtmodid, force, mrnset, mapset, split, loopset, or cggtmod. SEAS does not support hexadecimal digits as the value of the global title address parameter. If you wish to use any of these parameters or use hexadecimal digits as the value for the global title address parameter, perform the “Changing a Global Title Translation” procedure in Database Administration - GTT User's Guide using the SEAS FLOW-THRU
command with the EAGLE commands.
If the Flexible GTT Load Sharing feature is enabled, shown by the MRNSET
field in the EAGLE rtrv-gtt
output, and the routing indicator of the global title translation is G
(the EAGLE value GT
), the global title translation can be changed in this procedure only if the global title translation is assigned to the default MRN set. All the attributes of the global title translation can be changed except for the following:
- The MRNSET value cannot be changed.
- The routing indicator value cannot be changed.
- If the point code is changed, the new point code must be assigned to the default MRN set.
If the Flexible GTT Load Sharing feature is enabled, shown by the MAPSET
field in the EAGLE rtrv-gtt
output, and the routing indicator of the global title translation is D
(the EAGLE value SSN
), the global title translation can be changed in this procedure only if the global title translation is assigned to the default MAP set. All the attributes of the global title translation can be changed except for the following:
- The MAPSET value cannot be changed.
- The routing indicator value cannot be changed.
- If the point code is changed, the new point code must be assigned to the default MAP set.
The EAGLE XLAT
parameter does not have a SEAS equivalent. When global title translations are configured at the SEAS interface, the values for the SEAS parameters RI
, DPC

* The MSU being translated already contains the subsystem number. The DPC is translated and replaced, and the existing subsystem number in the MSU is unchanged and routed based on the new DPC and the existing subsystem number. General Notes:

The DPC, SSN and NRC
parameters of the SEAS CHG-GTT
command are not supported by the EAGLE. While these parameters must be specified with the SEAS CHG-GTT
command, these parameters are discarded when the SEAS CHG-GTT
command is processed by the EAGLE.
The range of global title addresses assigned to a global title translation can be extended or reduced to create a new range of global title addresses. The range can be extended so long as the new range of global title addresses does not overlap an existing range of global title addresses. The range can be reduced so long as the new end global title address parameter value is not smaller than the global title address parameter value.
For example, a global title translation contains this range of global title addresses: 9194600000 - 9194603000. The range of global title addresses can be extended to 9194604500 by specifying an end global title address value of 9194604500 parameter with the SEAS CHG-GTT
command. However, if another range of global title addresses begins with the value 9194604000, the end global title address value of 9194604500 cannot be specified with the SEAS CHG-GTT
command as the new range created with the end global title address value of 9194604500 would overlap the range of global title addresses beginning with the value 9194604000. In this situation, the maximum value for the end global title address value would be 9194603999.
Using the same example, the range of global title addresses can be reduced to 9194600000 - 9194601500 by specifying the end global title address value of 9194601500 with the SEAS CHG-GTT
command. The new range must lie inside of the original range. You cannot create the range 9194595000 - 9194600000 by specifying the end global title address value of 9194595000 parameter with the SEAS CHG-GTT
command.
Caution:
Changes to the range of global title addresses occur only if the both the global title address and end global title address parameters are specified and the values for either of these parameters, or both parameters are different from the original values in the global title translation. If the global title address and end global title address parameters are specified for the global title translation being changed, and you do not wish to change either of these values, make sure the original global title address and end global title address values are specified in the SEASCHG-GTT
command.
