The CTI provides information to the CTT about the IUT
Before performing a test session, the CTI file has to be prepared. The CTT delivery package includes a CTI template (for CTT 3.0) or a CTI specification file (for CTT 3.1) that provides guidance.
The CTI file shall contain:
the name of the manufacturer exactly as in the DLMS UA membership database;
NOTE The name of the licence holder is imported by the CTT from the licence file.
the FLAG ID of the manufacturer exactly as recorded in the FLAG IDs database;
the Management Logical Device Name, that shall be unique and shall start with the three-letter manufacturer ID (FLAG ID) assigned to the manufacturer;
the type of the Implementation Under Test (IUT, meter);
the serial number, that should allow identifying the device that has been tested;
the information related to the IUT itself: the Logical Devices and Application Associations including the application context, authentication mechanism, conformance block, security suite and security material for each Application Association;
the communication profile and its parameters;
any extra information as described in the CTI template / CTI specification file.
