Page 12: Maintenance Philosophy
GENERAL The precise structure of the message is given in input/ output (I/O) message manuals. Symptoms described in the The maintenance philosophy contained in this volume is IXL reflect the previous assumptions listed, and indicate based upon the design of equipment (hardware), diagnostic further conditions that are observable at the frame that software, and test equipment employed.
Page 13 TLP SUSPECTED FAULTY EQUIPMENT list. It is expected that this will lead to an identification of faulty circuits within the SD and possibly additional suspect circuit packs not previously identified. This level of trouble clearing is more complex and requires knowledge of the equipment, 1B Processor MTC terminal techniques, and SDs, PKs, PRs, etc.
