CHAPTER 6 NDA-24299 Page 156 Revision 1.0 POST INSTALLATION TEST Fusion and Non-Fusion Connection Tests STEP 2: Station A in self-node (Node A) dials the Physical Station Number for Station B in Node C. STEP 3: The call terminates to Station B via FCCS and non-FCCS. STEP 4: Confirm the speech condition is sufficient (no noise, not one-way speech, etc.). STEP 5: Replace the handset of STN A. STEP 6: Repeat the above steps for all Fusion links. 4.2 When Seizing a Trunk from an ATTCON STEP 1: The operator at the ATTCON in self-node (Node A) dials Physical Station Number for Station B in Node C. STEP 2: The call terminates to Station B via FCCS and non-FCCS. STEP 3: Confirm the speech condition is sufficient (no noise, not one-way speech, etc.) STEP 4: The operator at the ATTCON releases the call by pressing the CANCEL key.

NDA-24299 CHAPTER 6 Page 157 Revision 1.0 POST INSTALLATION TEST SDT Card Loopback Test 5. SDT Card Loopback Test The patterns for loopback test, which can be set by the SDT card, are as follows: 1. Local Loopback Loopback tests are performed only on the SDT card at the self-node. 2. Remote Loopback Loopback tests are performed between different nodes. The result of this test can be confirmed not at the self-node, but at the distant node. Figure 6-14 illustrates the loopback points of the SDT card. Figure 6-14 Loopback Points of SDT Card Test Procedure STEP 1: Designate the loopback test pattern by setting the P-SW key on the SDT (PA-SDTA) card. Refer to Figure 6-15. Figure 6-15 Loopback Setting by P-SW key on PA-SDTA Card Remote Loopback SDT PKG 2 Fusion Diagnosis Test Result (1) NG: Error detection at self-node.

CHAPTER 6 NDA-24299 Page 158 Revision 1.0 POST INSTALLATION TEST SDT Card Loopback Test STEP 2: Make sure that the “LPB” lamp on the PA-SDTA card, or the “SYCxx” lamp on the PA-SDTB card lights steady-green. STEP 2.5: When the loopback pattern is “local loopback,” confirm that the “OPT” and “SYNC” lamps are both OFF on the PA-SDTA card. (“OPT” and “SYNC” lamps are OFF = Result of loopback test is fine) STEP 3: Return the key settings of the P-SW key (on PA-SDTA card: see Figure 6-15) to the original position.

The number of cards and cables may vary depending on the system. Figure 7-1 Related Hardware 2. 3-B PM C-level Infinite Loop (Permanent) This message is displayed when a C-level program abnormal state has been detected as permanent. When the abnormal state is detected by the Port Microprocessor (PM) on an FCH card, 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, issuing 3-B system message. Refer to Figure 7-2.

NDA-24299 CHAPTER 7 Page 163 Revision 1.0 TROUBLESHOOTING 3-C PM C-level Infinite Loop (Temporary) 3. 3-C PM C-level Infinite Loop (Temporary) This message is displayed when the C-level program has been detected as abnormal by the Port Microprocessor (PM) mounted on the FCH (PA-FCHA) card. In this instance, the system performs an appropriate restart (B-monitor/Initial restart) according to the frequency of the failures. Refer to Figure 7-5. If the frequency exceeds 15 times an hour, it is judged as permanent. See 3-B PM C-level Infinite Loop (Permanent). Figure 7-5 3-C PM C-level Infinite Loop (Temporary) Note: B-monitor Restart: Ports whose link has already been established remain connected, while ports processing a call-origination may be released. Initial Restart: All ports on the circuit card are force released to be placed in idle state. 3.1 Repair Procedure STEP 1: If the 3-C message has been displayed only once or twice, monitor the failure for a while. Otherwise, move to STEP 2. STEP 2: Initialize the indicated FCH (PA-FCHA) card using the MB key. See Figure 7-3 “How to Initialize the FCH (PA-FCHA) card.” When the LED on the FCH card lights green, and the related system messages are not displayed, monitor the system for a while. Otherwise move to STEP 3. STEP 3: Replace the FCH card, following the procedure listed in Figure 7-4 “How to Replace FCH (PA- FCHA) card.” 4. 3-D PM Lockup Failure (Permanent) The CPU sends diagnosis data at periodic intervals to the Port Microprocessor (PM) on FCH (PA-FCHA) cards to monitor the PM. If the CPU cannot receive the return data within a predetermined time, the system displays the data in Figure 7-6. When the failure is detected more than 15 times per hour, the failure is judged as permanent. Otherwise, 3-E PM Lockup Failure (Temporary) is displayed.

CHAPTER 7 NDA-24299 Page 164 Revision 1.0 TROUBLESHOOTING 3-E PM Lockup Failure (Temporary) 4.1 Repair Procedure STEP 1: Make sure that station-to-station connections can be established in the PIM containing the indicated FCH (PA-FCHA) card. If the station-to-station connections cannot be established, the PIM is faulty. Repair the PIM. Otherwise, move to STEP 2. STEP 2: Initialize the FCH card using the MB key. See Figure 7-3 “How to Initialize FCH (PA-FCHA) Card.” When the LED lights green and no system message related to this failure displays again, monitor the system for a while. Otherwise, move to STEP 3. STEP 3: Replace the FCH card. Refer to Figure 7-4 “How to Replace FCH (PA-FCHA) Card.” 5. 3-E PM Lockup Failure (Temporary) The CPU sends diagnosis data at periodic intervals to the Port Microprocessor (PM) on the FCH (PA-FCHA) cards to monitor the PM. If the CPU cannot receive the return data within a predetermined time, the system displays the data in Figure 7-7. When the failure is detected more than 15 times per hour, the failure is judged as permanent. Otherwise, 3-E “PM Lockup Failure (Temporary)” is displayed. Figure 7-7 3-E PM Lockup Failure (Temporary) Note: B-monitor Restart: Ports whose link have already been established remain connected, while ports processing a call-origination may be released. Initial Restart: All ports on the circuit card are force released to be placed in idle state. 5.1 Repair Procedure STEP 1: If this system message has been displayed only once or twice, monitor the failure for a while. Otherwise, move to STEP 2. STEP 2: Initialize the FCH (PA-FCHA) card using the MB key. See Figure 7-3 “How to Initialize FCH Card.” If this message is not displayed anymore, monitor the FCH card for a while. Otherwise, move to STEP 3. STEP 3: Replace the FCH card, referring to Figure 7-4 “How to Replace FCH (PA-FCHA) Card.” 1. xx0x 0000 0000 0000 2. 0000 0000 0000 0000.........
