This TLV is used to add Global Title (GT) entries. It is not used for Global Title Translation (GTT) immediately. You can configure multiple GT entries before you activate them using the 0x09CE Build Index Table.
These newly configured GT entries are stored on the SS7 card but do not take effect until the SS7 card receives the Build Index command.
You can add 1,000 GT entries at a time up to a maximum of 100,000 for an SS7 card. If you configure GT entries after exceeding this maximum, you will receive the error code 0x552D. When the GT entry has been in the Active GT table you will receive the error code 0x5529. When the GT entry has been Standby GT table you will receive the error code 0x5528.
