Increase the timeout allowed for a TDM download. 5. Resolve NECOMMS error on the OPC for AN18 upgrades. 6. IRTU testing fails for individual lines of second host and higher. 7. Resolve a telemetry alarm software trap. 8. TXC robustness. 9. Allow for proper diagnosis of Hong Kong POTS cards. ---------------------------------------------------------------------- 1. Timeouts when opening Provisioning Manager. * Description: Operations requiring the querying of UDLC, Tandem or TR-08 line service provisioning would fail to respond from the Network Element, causing the Provisioning Manager to fail to open. The customer most likely to see this issue would have few (less then 30) UDLC non-switched services provisioned, but have a large number (in the neighborhood of 500 ) of integrated subscribers. * Impact: Opening the Provisioning Manager at the OPC would fail, or be inconsistent in opening. * Pre-Increment work-around: TL1 can be used to provision circuits on the Network Element. 2. Premature conviction of lines as Babblers. * Description: This increment loosens the parameters used to convict a line as a babbler. A babbling line is defined as one that has a hardware issue, which is continually messaging the AccessNode processor for action. Through the investigation of field issues, it was noted that some lines were being prematurely convicted as a babbling line. * Impact: A marginal line would prematurely be failed by the system, convicted as a babbling line. * Pre-Increment work-around: None. The line card convicted as a babbler would be taken out of service. Manual action would have been required to restore service. 3. ILC test lines will not work after they have been remapped (DMSPROV) * Description: For customers who have used the DMSPROV tool to remap IRTU ILC test circuits, testing from the DMS host would not complete. The DMS would inform the user that the test equipment was unavailable. The ILC circuit is what the DMS utilizes to the Network Element to test with the IRTU circuit pack. The typical use for using the DMSPROV tool is AccessNode applications utilizing the UE9000. * Impact: All switch diagnostics involving the IRTU would fail. * Pre-Increment work-around: Move the ILC circuits to default mapping. 4. Increase the timeout allowed for a TDM download. * Description: TDM downloads can take quite some time, depending on system resources. This increment increases the amount of time allowed for a download timeout to occur, making the download of the TDM less likely to fail due to a timeout expiry. * Impact: Longer time is allotted for download to the TDM before a timeout is declared. * Pre-Increment work-around: Download the TDM's during low utilization periods. 5. Resolve NECOMMS error on the OPC for AN18 upgrades. * Description: For AN18 upgrades, the UPGUI tool used to upgrade peripheral processors (ANX, LAIC, TDM) would experience failures. The most common error encountered would be one of a loss of association to the Network Element, when in fact the association had not dropped. This increment makes the UPGUI tool more robust. * Impact: Better performance when upgrading peripheral processors as noted above. * Pre-Increment work-around: In some instances, the manual recovery procedures detailed in the upgrade CAP would need to be used. * Removal Note: This change introduces a NE to OPC communications timer, and the removal of this increment will cause the Network Element to trap within 5 minutes of it's removal. Each node will generate one trap each time the increment is removed. In order to validate that the trap is the one known, open logutil as seen below. >logutil t Done. CM TRAP JUL31 14:31:55 9300 Trap number 4, Bus error. At 01B3BAE0 (Procname Unknown), PROCID= #C505 #104E: OPCNECOM, Entry Module: OPCNECOM SSTI: #0330 Current count of this trap type: 1 Traceback: 01AEFE3C=OPCNECOM.AE02:OPCNECOM_E+#02B4 0122A0DC=MODULES.DT02:INITIALIZEP+#0014 01214ABE=PROCS.FA01:LIVEANDD+#0012 Fault address FFFF0000 (Not Found) MCM address hold register FFFF0000 MMU Status Register FDFD MMU Function Code 0006 Bus Signal Status Read Fault Indication Register 0028 *** PLEASE CAPTURE FULL TRAPINFO FOR DEBUGGING *** LOGUTIL: Some of the data above will be different, but these three items will confirm this trap: - The phrase "Bus error" on line 2. - The phrase "Procname Unknown" on line 3. - The phrase "OPCNECOM" on line 4. - The phrase "OPCNECOM_E+#02B4" on line 7. If the trap listed meets these listed four criteria, then the trap can be ignored, and the alarm cleared. To clear the trap alarm, perform the following steps: 1. Log into the NE with admin privileges. 2. Type "TRPALMCI" at the user interface. 3. Type "CLEARTRP" at the user interface. The alarm should now be cleared. 6. IRTU testing fails for individual lines of second host and higher. * Description: Similar to number three above, individual lines that have been remapped with the DMSPROV tool will not be able to be tested from a second or greater host (IG 2 through 5). Depending on the use of DMSPROV, some or all lines from the second or higher host could be affected. * Impact: Testing from the DMS using the IRTU would fail for individual lines that have been remapped. * Pre-Increment work-around: If the lines were above UE9000 shelf one, no work-around is available. For lines on UE9000 shelf 1, only lines that do not use default mapping would be impacted. 7. Resolve a telemetry alarm software trap. * Description: For customers using parallel telemetry, retrieval of alarms could cause a trap. This increment prevents the trap. * Impact: Could not retrieve alarms. * Pre-Increment work-around: None. 8. TXC robustness. * Description: Changes introduced in AN17 to allow for the TXC to drop into Holdover mode have been migrated into AN18 with this increment. This software increment enhances TXC stability during on-board power supply failures. Additionally, the increment provides new functionality that allows the incoming timing reference to switch if the active timing reference is degraded, as opposed to a loss of signal condition. This feature requires that DS1 Performance Monitoring (PM) Alerts be turned on for the primary and if so equipped, secondary timing reference. If the secondary reference is also experiencing trouble, or is non-existent, then the TXC will enter into holdover mode. See the Special Instructions section of this increment for details on turning on the PM alerts for the DFA timing sources. * Impact: None. New functionality delivered. * Pre-Increment work-around: Not applicable. 9. Allow for proper diagnosis of Hong Kong POTS cards. * Description: In AN18, DMS switch (CSC) tests of Hong Kong POTS24 cards (NTNP40BA) would fail the off-hook test, generating a LINE101 log in the DMS-100 stating: Test failed: Off-hook ACTION REQUIRED Replace card. This has been resolved with the application of this increment. * Impact: Switch diagnostics would fail to the Hong Kong POTS24 cards (NTNP40BA). * Pre-Increment work-around: None.

The following message displayed in the ISD tool is considered normal when the increment is being applied to a TBM shelf: **WARNING: CI command for unknown package The increment will complete the apply to the TBM shelf in spite of the above warning. To turn on Performance alerts, to be used in conjunction with number eight above: 1. Select Performance Monitoring 'perfmon' at the MAPCI display. 2. Select Facility Performance 'facperf DS1 X Y' NOTE: "X" is the DS1 Mapper card used for the timing reference as seen at the 'pr;trefprot;trefsrc' screen.
