NDA-24307 CHAPTER 3 Page 97 Issue 1 SYSTEM MESSAGES This message displays when a C-level program abnormal state is detected as permanent. When the Port Microprocessor (PM) on an LC/TRK card detects the abnormal state, the PM places the card into make-busy status. If the failure occurs more than 15 times an hour, the system judges the failure as permanent, and issues the [3-B] system message. ➀Faulty Circuit Card Mounting Location 1: XX00 0000 0000 0000 2: 0000 0000 0000 0000 3: 0000 0000 0000 0000 ➀...

CHAPTER 3 NDA-24307 Pag e 9 8 Issue 1 SYSTEM MESSAGES This message displays when C-level program is detected as abnormal by the Port Microprocessor (PM) mounted on an LC/TRK card. If the failure occurs less than 15 times/hour, and a B-monitor/Initial restart executes as the result, the failure is judged as temporary and this message is created. ➀Faulty Circuit Card Mounting Location ➁ PM Restart Type Note:B-monitor Restart: Ports whose link have already been established remain connected.

NDA-24307 CHAPTER 3 Page 99 Issue 1 SYSTEM MESSAGES At the periodic interval, the CPU sends diagnosis data to the Port Microprocessor (PM) on LC/TRK cards in order to monitor the PM. If the CPU cannot receive the return data within a predetermined period of time, the system displays this data. When the failure is detected more than 15 times per hour, the failure is judged as permanent. ➀ Faulty Circuit Card Location See Chapter 5 for repair procedure. 1: XX00 0000 0000 0000 2: 0000 0000 0000 0000 3: 0000...

NDA-24307 CHAPTER 3 Page 101 Issue 1 SYSTEM MESSAGES This message displays when over current of the operating power (DC-48V) is supplied from the ATI/ELC circuit card to the Attendant Console/Dterm. When this fault occurs, the related circuit card is placed into make- busy state and stops supplying power. ➀ Faulty PM Location 1: XX00 0000 0000 0000 2: 0000 0000 0000 0000 3: 0000 0000 0000 0000 ➀ 4: 0000 0000 0000 0000 5: 0000 0000 0000 0000 6: 0000 0000 0000 0000 7: 0000 0000 0000 0000 8: 0000 0000 0000...
