These must be manually restored afterward. nRe-enter all Maintenance Object busyouts. nRe-enter wakeup calls and do-not-disturb stations. nRestore attendant feature settings. nNotify Administration and ACD users that the update is complete. nRe-enable TTI changes by the change system-parameters features. nOn the change system-parameters maintenance form, restore Alarm Origination, Save Translations, CPE Alarm Level and SPE Interchange fields and Scheduled Daily Maintenance times to their original settings. nManually reset any speakerphones which derive power from the switch by pressing the button on the voice terminal. Backing Out of a Software Update If fatal hardware errors or memory faults prevent the update from completing, the system must be recovered and the update backed out. If the update command has already been entered, follow normal escalation procedures. Backing out after this point is hazardous and may leave the system in a corrupted state. Software Update Procedure — Simplex SPE After making the preparations described above, execute the following sequence of steps, entering the commands shown in bold type. This part of the procedure normally takes about 3 1/2 hours. Screen output for each command is described in Chapter 8, ‘‘ Maintenance Commands’’. If errors are encountered after entering the update software command, follow normal escalation procedures. Avoid touching the keyboard while the save or upgrade commands are running since doing so may cause diagnostic messages to be lost.

DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 Additional Maintenance Procedures Page 6-10 DS1 CPE Loopback Jack (T1 Only) 6 DS1 CPE Loopback Jack (T1 Only) Using the DS1 CPE Loopback Jack (apparatus code 700A, comcode 107988867), a technician can test the DS1 span between the system and the network interface point. The loopback jack is required when DC power appears at the interface to the ICSU. The loopback jack isolates the ICSU from the DC power and properly loops the DC span power . NOTE: The loopback jack operates with any vintage of TN767E (or later) or TN464F (or later) DS1 circuit packs and with G3V3 EDI release 3 (or later) software. The loopback jack operates with the 120A2 (or later) Integrated Channel Service Unit (ICSU) only; not the 31xx series of Channel Service Units or other external CSUs or earlier ICSUs. Loopback Jack Installation Configurations Using a Smart Jack The preferred location of the loopback jack is at the interface to the Smart Jack. This provides maximum coverage of CPE wiring when remote tests are run using the loopback jack. If the Smart Jack is not accessible, install the loopback jack at the extended demarcation point. 1. If there is no extended demarcation point, install the loopback jack directly at the network interface point as shown in Figure 6-1 . 2. If there is an extended demarcation point and the Smart Jack is not accessible, install the loopback jack as shown in Figure 6-2 . 3. If there is an extended demarcation point, but the Smart Jack is accessible, install the loopback jack as shown in Figure 6-3 . backup disk20 Make extra backup copies of the new files as needed. set vector f spe-maint1 Sets the coredump vector to take a coredump when the system reboots. Restore the system as described above. Table 6-2. Software Update—Duplicated SPE — Continued StepTime (m in) Remarks Continued on next page
DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 Additional Maintenance Procedures Page 6-11 DS1 CPE Loopback Jack (T1 Only) 6 Configurations Without a Smart Jack 1. Install the loopback jack at the point where the cabling from the ICSU plugs into the “dumb” block. If there is more than one “dumb” block, choose the one that is closest to the Interface Termination feed or the fiber MUX. This provides maximum coverage for loopback jack tests. Refer to Figure 6-4 and Figure 6-5. Installation 1. To install the loopback jack, simply disconnect the RJ-48 (8-wide) connector (typically an H600-383 cable) at the appropriate interface point and connect the loopback jack in series with the DS1 span. See Figure 6-1 through Figure 6-5 . 2. Plug the H600-383 cable from the ICSU into the female connector on the loopback jack. 3. Plug the male connector on the loopback jack cable into the network interface point. NOTE: Do not remove the loopback jack after installation. This is not a test tool and should always be available to remotely test a DS1 span. Administration 1. At the management terminal, enter change ds1 . The “location” is the DS1 interface circuit pack for which the loopback jack was installed. 2. Be sure the “near-end CSU type” is set to integrated. 3. On page 2 of the form, change the supply CPE loopback jack power field to y. NOTE: Setting this field to y informs the technician that a loopback jack is present on the facility. This allows a technician to determine that the facility is available for remote testing. 4. Enter save translation to save the new information. DS1 Span Test This test should only be performed after the DS1 circuit pack and the 120A2 (or later) ICSU have been successfully tested using appropriate maintenance procedures. The DS1 span test consists of 2 sequential parts. Each part provides a result indicating if there is a problem in the CPE wiring. CPE wiring may be considered problem-free only if the results of both parts are successful.
DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 Additional Maintenance Procedures Page 6-12 DS1 CPE Loopback Jack (T1 Only) 6 The first part of the span test powers-up the loopback jack and attempts to send a simple code from the DS1 board, through the wiring and loopback jack, and back to the DS1 board. Maintenance software waits about 10 seconds for the loopback jack to loop, sends the indication of the test results to the management terminal, and proceeds to the second part of the test. The second part of the test sends the standard DS1 3-in-24 stress testing pattern from the DS1 board, through the loopback jack, and back to a bit error detector and counter on the DS1 board. The bit error rate counter may be examined at will via the management terminal, and provides the results of the second part of the test. The test remains in this state until it is terminated so that the CPE wiring may be bit error rate tested for as long as desired. 1. Busy out the DS1 circuit pack by entering busyout board UUCCSS (where UUCCSS is the cabinet, carrier, and slot number of the DS1 board). 2. At the management terminal, enter change ds1 and verify the near-end csu type is set to integrated. 3. Change to page 2 of the DS1 administration form and confirm that the TX LBO field is 0dB. If not, record the current value and change it to 0dB for testing. Press Enter to implement the changes or press Cancel to change nothing. 4. Enter test ds1-loop cpe-loopback-jack. This turns on simplex power to the loopback jack and waits about 20 seconds for any active DS1 facility alarms to clear. A “PASS” or “FAIL” displays on the terminal. This is the first of the 2 results. A “FAIL” indicates a fault is present in the wiring between the ICSU and the loopback jack. The loopback jack may also be faulty. A “PASS” only indicates that the loopback jack looped successfully, not that the test data contains no errors. If a “PASS” is obtained, continue with the following steps. NOTE: The loss of signal (LOS) alarm (demand test #138) is not processed during this test while the 3-in-24 pattern is active. 5. Enter clear meas ds1 loop to clear the bit error count. 6. Enter clear meas ds1 log to clear the performance measurement counts. 7. Enter clear meas ds1 esf to clear the ESF error count. 8. Enter list meas ds1 sum to display the bit error count. Refer to Table 6-3 for troubleshooting information.

Repeat Steps 5 through 8 as desired to observe bit error rate characteristics. Also, wait 1 to 10 minutes between Steps 5 through 7. One minute without errors translates to better than a 1 in 10 to the eighth error rate. Ten minutes without errors translates to better than a 1 in 10 to the ninth error rate. 10. If the test runs for 1 minute with an error count of 0, confirm that the 3-in-24 pattern error detector is operating properly by entering test ds1-loop inject-single-bit-error. This causes the 3-in-24 pattern generator on the DS1 circuit pack to inject a single-bit error into the transmit pattern. A subsequent list meas ds1 summary command displays the bit error count. If a count greater than 1 is displayed, replace the ICSU and retest. If the problem continues, replace the DS1 circuit pack. Table 6-3. DS1 Span Troubleshooting Displayed Field Function Indication Test: cpe-loopback-jackPattern 3-in-24 The loopback jack test is active. Synchronized Y or NIf “y” displays, the DS1 circuit pack has synchronized to the looped 3-in-24 pattern and is accumulating a count of the bit errors detected in the pattern until the test has ended. If “n” displays, retry the test 5 times by ending the test per Step 11 and re-starting the test per Step 4. If the circuit pack never synchronizes, substantial bit errors in the 3-in-24 pattern are likely. This could be intermittent connections or a broken wire in a receive or transmit pair in the CPE wiring. Bit Error Count Cumulative count of detected errors If there are no wiring problems, the counter remains at 0. A count that pegs at 65535 or continues to increment by several hundred to several thousand on each list meas command execution indicates intermittent or corroded connections, severe crosstalk, or impedance imbalances between the two conductors of the receive pair or the transmit pair. Wiring may need replacement. Note that “ESF error events” counter and the ESF performance counter summaries (“errored seconds”, “bursty errored seconds”, and so forth) will also increment. These counters are not used with the loopback jack tests. However, they will increment if errors are occurring. Counters should be cleared following the test.

Terminate the test by entering test ds1-loop end cpe-loopback-jack-test. Wait about 30 seconds for the DS1 to re-frame on the incoming signal and clear DS1 facility alarms. Loopback termination fails under the following conditions: a. The span is still looped somewhere. This could be at the loopback jack, at the ICSU, or somewhere in the network. This state is indicated by a fail code of 1313. If the red LED on the loopback jack is on, replace the ICSU. Re-run the test and verify that the loopback test terminates properly. If not, replace the DS1 circuit pack and repeat the test. b.The DS1 cannot frame on the incoming span’s signal after the loopback jack is powered down. This means that there is something wrong with the receive signal into the loopback jack from the “dumb” block or the Smart Jack. If the service provider successfully looped and tested the span, up to the Smart Jack, this condition isolates the problem to the wiring between the loopback jack and the Smart Jack. Refer to “Loopback Jack Fault Isolation Procedures” for information on how to proceed in this case. The test cannot be successfully terminated until a good signal is received. To properly terminate the test before a good receive signal is available, enter reset board . 12. Restore the “TX LBO” field to the original value recorded in Step 2. 13. Release the DS1 circuit pack using the release board UUCCSSpp command. 14. Leave the loopback jack connected to the DS1 span. Loopback Jack Fault Isolation Procedures This section describes the possible DS1 configurations in which the loopback jack may be used. These configurations are: when the DS1 provider includes a Smart Jack, when no Smart Jack is provided at all, and when sites use fiber multiplexers. These configurations are separated into “Configurations Using a Smart Jack” and “Configurations Without a Smart Jack.” Configurations Using a Smart Jack The addition of the loopback jack and the presence of a Smart Jack divides the DS1 span into 3 separate sections for fault isolation. These sections are shown in Figure 6-1 through Figure 6-3 for the different span configurations. They are: Section 1: Between the 120A2 (or later) ICSU and the loopback jack. Section 2: Between the loopback jack and the Smart Jack (network interface point). Section 3: From the Smart Jack to the CO. It is necessary to contact the DS1 provider to run this test.
