Unless a waiver has been granted under Section 14, MLTS Operators shall arrange to update the ALI Database with the appropriate Master Street Address Guide (MSAG) valid address and callback information for each MLTS telephone, so that the location information specifies the ERL of the caller. These updates shall be made as soon as practicable for new MLTS installation, or within one business day of record completion of the actual changes for previously installed systems.
