Normal 0 false false false EN-CA X-NONE X-NONE MicrosoftInternetExplorer4
The TB640_MSG_ID_SS7_SCCP_OP_GTT_ASSO_ALLOC (request/response) message is used to configure associations for Global Title Translation of the SCCP layer. An association specifies the translation procedure to be used for a particular type of global title. The user configures an association for each global title type in SCCP.

General explanation of the parameters of Action specific configuration:
- The action type parameter (ActionType) specifies the type of action for this association. Allowable values:
Table SEQ Table \* ARABIC 84 - SCCP GT action type
SSN value to identify SCCP user
Description
TB640_SS7_SCCP_ACTION_TYPE_FIX
Use a fixed range of digits to perform GTT. For example, use first 3 digits.
TB640_SS7_SCCP_ACTION_TYPE_VARIABLE_ASCENDING
Use variable number of digits GTT in ascending order. For example, use digits 4 to 6 in a variable fashion to perform GTT. In this case, variable means match the fourth digit, and if no match, then match the fourth and fifth digits, and so on.
TB640_SS7_SCCP_ACTION_TYPE_VARIABLE_DESCENDING
Use variable number of digits GTT in descending order. For example, use digits 4 to 6 in a variable fashion to perform GTT. In this case, variable means match the sixth digit, and if no match, then match the fifth and sixth digits, and so on.
TB640_SS7_SCCP_ACTION_TYPE_GT_TO_PC
Use digits in incoming GT as the point code for routing purposes. This type of GTT is used in ISNI.
TB640_SS7_SCCP_ACTION_TYPE_CONST
Always translate the incoming GT to a fixed address.
TB640_SS7_SCCP_ACTION_TYPE_INSERT_PC
Insert DPC before incoming GTAI and change TT, ES and NAI, leaving GTAI unchanged. This action is for modifying calling party address at an international Gateway, when message is entering international network, originating form a national network and having calling address in national specific format with Generic Numbering Plan. DPC inserted is the point code of the international Gateway, having capability to translate back the international address format to national specific address in response message. The DPC inserted, need not be the self point code of the international Gateway modifying the calling party address.
TB640_SS7_SCCP_ACTION_TYPE_STRIP_PC
If first six digits are self point code in international format, strip off first six digits from the GTAI. Then do the translation and replace TT, ES, and NAI. Examine the DPC of the translated address, if it is self, do translation of the resulting address again else message will be forwarded to DPC for further translation without changing GTAI of the called address.
