CHAPTER 5 OPERATION TEST PLO Operation Test NEAX2000 IVS2 ISDN System Manual ND-70919 (E), Issue 1.0 Page 195 PLO OPERATION TEST To confirm the PLO operation do the following tests: Clock Signal Generation Test Clock Signal Synchronization Test To be tested when the PBX is a clock receiver office. Interoffice Synchronization Test Source Office Mode Test To be tested when the PBX is a clock source office. Clock Signal Generation Test This test checks to see if the PLO keeps generating clock signals at the frequency of the previous source clock, when the source clock signal from network have stopped. Do the following procedure using “In Service” transmission lines. STEP 1: On all the DTI/PRT/BRT cards mounted in PIM0, set the switches as follows to stop the external clock signal input: 30DTI card: SW-1 and SW-2 to OFF PRT/24DTI card: SW0-1 and SW0-2 to OFF BRT card: SW0-2 and SW0-3 to OFF 2BRT card: SW11-2 and SW11-3 to OFF – The CLK lamp on the MP card goes out. STEP 2: Originate an outgoing call via trunks. STEP 3: After an outgoing connection via trunks has been established, confirm interoffice synchronization and speech quality as follows: On the DTMF telephone set, keep pressing any dial button. Check to see if noise periodically occurs on the DTMF signals coming from the calling station in the opposite office. Do the above test again in the opposite direction. STEP 4: On all the DTI/PRT/BRT cards mounted in PIM0, restore the switches as the state before testing to input the external clock signals. – The CLK lamp on the MP card lights. NOTE:If noise periodically occurs, replace the MP card after checking the switch settings on the MP card, and do the above test again.
NEAX2000 IVS2 ISDN System ManualPage 196 ND-70919 (E), Issue 1.0 CHAPTER 5 OPERATION TEST PLO Operation Test Clock Signal Synchronization Test This test checks to see if the PLO keeps synchronizing with the external clock signals, when the external clock signals from network has input again after it has stopped once. Do the following procedure using “In Service” transmission lines. (1) When providing one clock supply route STEP 1: On the DTI0/PRT0/BRT0 card extracting clock signals, set the switches as follows to stop the external clock signal input: 30DTI0 card: SW-1 and SW-2 to OFF PRT0/24DTI0 card: SW0-1 and SW0-2 to OFF BRT0 card: SW0-2 and SW0-3 to OFF 2BRT0 card: SW11-2 and SW11-3 to OFF – The CLK lamp on the MP card goes out. STEP 2: Originate an outgoing call via trunk. STEP 3: After an outgoing connection via trunk has been established, confirm interoffice synchronization and speech quality as follows: On the DTMF telephone set, keep pressing any dial button. Check to see if noise periodically occurs on the DTMF signals coming from the calling station in the opposite office. Do the above test again in the opposite direction. STEP 4: On the DTI0/PRT0/BRT0 card, restore the switches as the state before testing to input the external clock signals: 30DTI0 card: SW-1 to ON, SW-2 to OFF PRT0/24DTI0 card: SW0-1 to ON, SW0-2 to OFF BRT0 card: SW0-2 to ON, SW0-3 to ON 2BRT0 card: SW11-2 to ON, SW11-3 to ON – The CLK lamp on the MP card lights. STEP 5: Originate an outgoing call via trunks.
CHAPTER 5 OPERATION TEST PLO Operation Test NEAX2000 IVS2 ISDN System Manual ND-70919 (E), Issue 1.0 Page 197 STEP 6: After an outgoing connection via trunks has been established, confirm interoffice synchronization and speech quality with the procedure shown in STEP 3. NOTE:If noise periodically occurs, replace the MP card after checking the switch settings on the MP card, and do the above test again. (2) When providing two clock supply routes STEP 1: On the DTI/PRT/BRT cards extracting clock signals, set the switches as follows to change the clock supply route from 0 to 1: 30DTI0 card: SW-1 to OFF, SW-2 to OFF 30DTI1 card: SW-1 to OFF, SW-2 to ON PRT0/24DTI0 card: SW0-1 to OFF, SW0-2 to OFF PRT1/24DTI1 card: SW0-1 to OFF, SW0-2 to ON BRT0 card: SW0-2 to OFF, SW0-3 to OFF BRT1 card: SW0-2 to ON, SW0-3 to OFF 2BRT0 card: SW11-2 to OFF, SW11-3 to OFF 2BRT1 card: SW11-2 to ON, SW11-3 to OFF STEP 2: Originate an outgoing call via trunks. STEP 3: After an outgoing connection via trunks has been established, confirm interoffice synchronization and speech quality as follows: On the DTMF telephone set, keep pressing any dial button. Check to see if noise periodically occurs on the DTMF signals coming from the calling station in the opposite office. Do the above test again in the opposite direction. STEP 4: On the DTI/PRT/BRT cards, set the switches as follows to stop the external clock signal input: 30DTI0/1 card: SW-1 and SW-2 to OFF PRT0/1, 24DTI0/1 card: SW0-1 and SW0-2 to OFF BRT0/1 card: SW0-2 and SW0-3 to OFF 2BRT0/1 card: SW11-2 and SW11-3 to OFF – The CLK lamp on the MP card goes out. STEP 5: Repeat STEP 2 and STEP 3 of this procedure.
NEAX2000 IVS2 ISDN System ManualPage 198 ND-70919 (E), Issue 1.0 CHAPTER 5 OPERATION TEST PLO Operation Test STEP 6: On the DTI0/1, PRT0/1, BRT0/1 cards, set the switches as shown in STEP 1 to input clock signals from the clock supply Route 1. STEP 7: Repeat STEP 2 and STEP 3 of this procedure. STEP 8: On the DTI/PRT/BRT cards, set the switches as follows to change the clock supply route from 1 to 0: 30DTI0 card: SW-1 to ON, SW-2 to OFF 30DTI1 card: SW-1 to OFF, SW-2 to ON PRT0/24DTI0 card: SW0-1 to ON SW0-2 to OFF PRT1/24DTI1 card: SW0-1 to OFF, SW0-2 to ON BRT0 card: SW0-2 to ON, SW0-3 to ON BRT1 card: SW0-2 to ON, SW0-3 to OFF 2BRT0 card: SW11-2 to ON, SW0-3 to ON 2BRT1 card: SW11-2 to ON, SW0-3 to OFF – The CLK lamp on the MP card lights.

Interoffice Synchronization Test This test checks to see if noise occurs while calling with the opposite office, by difference of the clock signal frequency between the offices. Do the following procedure using “In Service” trans- mission lines. STEP 1: Originate an outgoing call via trunks. STEP 2: Check the speech quality (if noise, distortion or click occurs during a few minutes) with the opposite office mutually. STEP 3: On the DTMF telephone set, keep pressing any dial button, and check to see if noise periodically occurs on the DTMF signals coming from the calling station in the opposite office.
CHAPTER 5 OPERATION TEST PLO Operation Test NEAX2000 IVS2 ISDN System Manual ND-70919 (E), Issue 1.0 Page 199 STEP 4: Do the above test again in the opposite direction.

Source Office Mode Test When the PBX is operated as a clock source office, do the following procedure using “In Service” transmission lines. STEP 1: Confirm that the following switches on all the DTI/PRT/BRT cards mounted in PIM0 are set to OFF: 30DTI card: SW-1 and SW-2 to OFF PRT/24DTI card: SW0-1 and SW0-2 to OFF BRT card: SW0-2 and SW0-3 to OFF 2BRT card: SW11-2 and SW11-3 to OFF STEP 2: Confirm the following switches on the MP card are set to OFF: SW2-2 and SW2-3 to OFF SW4-2 and SW4-3 to OFF STEP 3: Confirm indication lamps on the MP card. NOTE:When the CLK lamp lights on the MP card, the clock signal is not generated from the MP card. Check the switch settings on the DTI, PRT, BRT and MP card. For details of the lamp indications, refer to CHAPTER 4. STEP 4: Originate an outgoing call via trunks. STEP 5: After an outgoing connection via trunk has been established, confirm interoffice synchronization and speech quality as follows: On the DTMF telephone set, keep pressing any dial button. Check to see if noise periodically occurs on the DTMF signals coming from the calling station in the opposite office. Do the above test again in the opposite direction. NOTE:If noise periodically occurs, replace the MP card after checking the switch settings on the DTI/PRT/BRT and MP card, and do the above test again.
