Table 5-11 GTT Sets Elements

Element	Description	Data Input Notes
GTT Set Name	Name for the SCCP GTT Set, which must be unique within the VSTP site. This is a mandatory field.	Format: Text box Valid names are strings between one and 9 characters, inclusive. Valid characters are alphanumeric and underscore. The name must contain at least one alpha and must not start with a digit.
NPSN Name	Not Present Set Name (NPSN) is used to configure alternate GTT Set. While decoding the MSU to extract the key for lookup in the GTTSET of the set type, if the required parameter does not exist in the MSU and that parameter is optional for that opcode, then the NPSN parameter (if provisioned in the GTTSET) can be used to go to another GTTSET. If the NPSN is not provisioned, then it is treated as bad translation. NPSN comes in the FLOBR/MBR search path, 1 leading alphabetic character and up to 8 following alphanumeric characters and underscore.	Format: Drop down menu Range = Imsi/Msisdn/Vlrnb/Smrpoa/Smrpd Value can have one leading alphabetic character, up to 8 following alphanumeric characters, and underscore.
