Another important item in the configuration of a test is the opportunity to abstract information from the test and leave this information to be provided during startup of the execution. The protocol implementation conformance statements (PICS)/protocol implemantation extra information (PIXIT) information is structured as an informal questionnaire. The answers are mapped to parameters in TTCN and imported. The two different questionnaires contain slightly different information.

PICS
PICS contain information regarding the protocol. This could typically be optional parts, specific restrictions, or add-ons. This information will serve as a basis for determining which test cases are applicable.

PIXIT
PIXIT contains information regarding the physical setup and connection of the test that is not part of the protocol. This could be information regarding the system-under-test hardware, socket or telephone numbers, and other information to make the test more flexible and allow the person responsible for executing the test to stay out of the TTCN world and avoid rewriting anything in TTCN.
