TL-130200-1001 Serial Device Controller Testing Procedures9.13.1 Use the following steps to conduct the Serial Device Controller Test: 1. Select Option “5” from the Menu of Test Options. The system responds: TYPE THE SDC PORT # YOU WISH TO TEST (0 OR 1) > > _.2. If Off-Line Diagnostics is not running on this port go to step 4. Otherwise, the system responds: TYPE ANY CHARACTER AND IT WILL BE ECHOED ON THE TERMINAL. TYPE CONTROL-K TO EXIT FROM THIS TEST 3. Any character key typed on the terminal keyboard will be echoed at the terminal. 4. If the user selects “O“, the system responds: THE BAUD RATE IS REQUIRED FOR PORT 1 TYPE THE LETTER OF THE APPROPRIATE BAUD RATE: A. 110 BAUD B. 150 BAUD C. 300 BAUD D. 600 BAUD E. 1200 BAUD F. 2400 BAUD G. 4800 BAUD H. 9600 BAUD 5. Enter the correct letter and the system responds: ATTENTION SHOULD NOW BE DIRECTED TO THE PORT 1 DEVICE 6. To end the test, type CONTROL-K on the tested terminal. The system responds: SERIAL DEVICE CONTROLLER TEST OVER Fault Correction9.13.2 Replace the NSDC card (FB-20992-A). If the wrong character echoes on the terminal, reload the system and repeat the test. Tone Test9.14 This test checks the tone output of the System Pulse Code Modulation card (FB-20974-A). The test begins with a tone time slot number written into the control memory of the network. The user audibly and visually verifies each tone by listening and following the terminal display. 5210 6187M-355
TL-130200-1001Tone Test9.14.1Use the following steps to conduct the Tone Test: Testing Procedures1. Select option “6” from the Menu of Test Options. The system responds: TONE CARD TEST PICK A CONVENIENT PHONE WITH WHICH TO LISTEN TO THE TONES. ENTER THE PHYSICAL LOCATION OF THIS PHONE. FILE NUMBER (A -- > D) > > . . 2.

Type the correct circuit number. Test Results9.14.2 The following Tone Test results may appear: 1. When the Tone Test is successfully completed, the system immediately connects the phone to the first system tone and prints the tone description.Tone Test outputs appear in Table 9.4.Type “G” to listen to the next tone. With the connection of the last tone, the system responds: END OF TONE TEST 2. If channel memory does not initialize, the system responds: NETWORK FAILURE: CAN’T WRITE TO CHANNEL MEMORY TESTING ENDED DUE TO ABOVE ERRORS 3. If control memory A or B is not initialized, the system responds: NETWORK FAILURE: CAN’T WRITE TO CONTROL MEMORY < A OR B >TESTING ENDED DUE TO ABOVE ERRORS M-3566B75210

If, during test, channel, control, or pad memory cannot be read, the system responds: READ AFTER WRITE FAILURE MEMORY FAILURE LOCATION IS: XXXX TESTING ENDED DUE TO ABOVE ERRORS NOTE: See Network Test Results (Paragraph 8.11) to memory address of the card causing the problem. 6. The system will continue sending the same tone if a “G” is not entered to send the next tone. 7. If the phone tested in steps 1 through 4 does not actually exist, the system responds: PHONE HARDWARE NOT AVAILABLEFault Correction9.14.3 The following steps correct faults detected by the Tone Test: 1. If the problem is found to be initializing or writing to channel, control, or pad memory, replace the Channel Memory 8085 card (FB-17218-A). Reinstall the original card if the problem continues after replacement. 2. Replace the System Pulse Code Modulation card (FB- 20974-BOA) if tones do not work. Initialize the new card by writing “FF” into address 08FF on memory page DO. 3. Repeat the Tone Test. 4. Reinstall and initiate the original card. Conduct the Network Test and/or the Line/Trunk Test on the circuit if the tones still do not work. 5. Check the data base for a different phone and repeat the Tone Test, if the original phone hardware was not available. Attendant Interface Card9.15 This test checks for transmission errors on the Attendant Interface Number 2 (ATT12) card (FB-17208-A). The test consists of sending a data pattern out of the card and looping it back to the input. The two data patterns are compared to see if the data pattern received is exactly the same as the data pattern sent. The test flags an error if the two data patterns somehow are different. Temporary wiring changes are required to conduct this test. Exercise extreme care when making these wiring changes. 52108f87M-359
TL-130200-1001Attendant Interface9.15.1Use the following steps to conduct the Attendant Interface Card TestCard test: Testing Procedures1. Remove the Attendant Interface card (FB-17208-A) from the cabinet. Make sure that all four dip-toggle switches are in the off position. Reinstall the card into the cabinet. 2. Disconnect the cable for the Attendant/BLDU interface on the Attendant Interface card. 3. Strap together the transmit (TRAN) and receive (REC) leads on the Attendant Interface card (FB-17208-A). Pin 93 is strapped to pin 95 for Port 0 while pin 56 is strapped to pin 58 - for Port 1. 4. Select Option “7” from the Menu of Test Options. The system responds: ATT12 CARD TEST ENTER THE LOCATION OF THE ATT12 CARD FILE NUMBER (A -- >) > >..5. Type the correct file letter. The system responds: SLOT NUMBER (0 -- > 11) > >6. Type the correct universal card slot number. The system responds: CIRCUIT NUMBER (0 OR 1) > >7. Type the correct circuit number (port) to test. Test Results9.15.2 The following Attendant Interface Card Test results may appear: 1. If the ATT12 card passes the test, the system responds: ATT12 CARD PASSES TEST 2. If the ATT12 card fails the test, the system responds: ATT12 CARD FAILURE, DATA = XX (XX = data pattern which caused failure) 3. If test could not start due to the lack of a steady signal, the system responds: NO READY SIGNAL FROM ATT12 CARD 4. If no phone hardware exists, the system responds: M-360 8187PHONE HARDWARE NOT AVAILABLE 5210
TL-130200-1001Fault Correction9.15.3 The following steps correct faults detected by the Attendant Interface Card Test: 1. Check the transmit and receive strapping if a “NO READY “signal error occurs. Also, remove the AMP connector from the ATT12 card slot and repeat the test. Replace the ATT12 card ifthe “NO READY“ signal error appears again and repeat the test. 2. If the ATT12 card itself failed the test, replace the card, and repeat the test.3. If the actual phone hardware was not available, check for a different instrument, and repeat the test. Line/Trunk Test9.16 This test checks the two-way connection between a specified phone and a test phone. Due to the lack of a central office response, only those trunk circuits found on the Direct- Inward-Dialing (DID) Trunk card (PILT, FB-51280-A) are tested. Line circuits found on PCM Off-Premises Station Line cards (POPS, FB-17250-A) and PCM Line Circuit cards(PLCC, FB-17254-1A) are also tested. Attach phones to the circuits at the CDF by referring to Table 9.5.an 9.6. 5210667M-361

Type the correct response for the second line or trunk circuit. Repeat steps two through five for this circuit.Test Results9.16.2 The following Line/Trunk Test results may appear: 1. With successful test completion the system responds: THE TWO SELECTED CIRCUITS NOW HAVE A TRANSMISSION PATH. WHEN YOU WISH TO EXIT FROM THIS TEST AND CLEAR THE NETWORK DEPRESS ANY CHARACTER > > . .

To end the test and break the transmission path, type any character. 2. If channel memory does not initialize, the system responds: NETWORK FAILURE: CAN’T WRITE TO CHANNEL MEMORY TESTING ENDED DUE TO ABOVE ERRORS 3. If control memory A or B is not initialized, the system responds: NETWORK FAILURE: CAN’T WRITE TO CONTROL MEMORYTESTING ENDED DUE TO ABOVE ERRORS 4. If pad memory is not initialized, the system responds: NETWORK FAILURE: CAN’T WRITE TO PAD MEMORY TESTING ENDED DUE TO ABOVE ERRORS 5. During test if it cannot read channel, control, or pad memory, the system responds: READ AFTER WRITE FAILURE MEMORY LOCATION IS: XXXX TESTING ENDED DUE TO ABOVE ERRORS NOTE: See Network Test Results (Paragraph 9.11) to find memory address of the card causing the problem. 6. If the phones tested in steps one through five do not actually exist, the system responds: PHONE HARDWARE NOT AVAILABLE Fault Correction9.16.3 The following steps correct faults detected by the Line/ Trunk Test: 1. If the transmission path is distorted, replace the tested PILTcard, POPS card, or PLCC card, and repeat the test. 2. If no transmission path was established, replace the tested PILT card, POPS card, or PLCC card, and repeat the test. 3. If replacement of the PILT, POPS, or PLCC card does not solve the problem, perform the Network Test (see paragraph 8.11).4. If the Network Test passes, reinstall the original card and repeat the Network Test. 81875210
