Course Outline

   Customized Lessons That Will Be Developed for You

 

Lesson 1 - Overview and Introduction to 5ESS Switch Analysis

This lesson, 5ESS Switch Overview, presents a brief overview of the 5ESS Switch.  This overview presents the hardware structure of the 5ESS Switch which includes defining the Administrative Module, Communication Module and Switching Module. It also states the function of the 5ESS Switching Module Peripheral Units and presents their connectivity to the Switching Module Processor and Time Slot Interchanger.  This establishes some of the basic knowledge needed for the remainder of this course. 

 

Lesson 2 – Plant 24:

The PLANT 24 lesson presents and analyzes the 5ESS Plant 24 Report.  The Plant 24 Report contains Parts that can be used to evaluate the level of service currently being provided by a 5ESS Switch.  This lesson presents these Plant 24 Parts and provides procedures on how to interpret them.  The emphasis is placed on identifying operational and service performance problems that have occurred.  During this lesson, three 5ESS Switches will be evaluated.  This lesson includes references to Alcatel-Lucent’s Dyna Text 5ESS Switch support documentation and relates procedures in the lesson to the documentation.

 

Lesson 3 – Output Messages and Log Files:

This Output Messages and Log Files lesson defines the characteristics of 5ESS Output Messages, how they are routed and the 5ESS Log Files they are “logged” to.  This is accomplished by presenting Output Message Classes and explaining how Output Messages are routed based on the Equipment Configuration Database (ECD) - Class Definition Record, form "classdef." The lesson also presents the Input Messages OP:LPS,MSGCLS and OP:OUTCLS which identify Message Class printing and logging status.  Next, the lesson addresses log files.  The log files addressed are the Administrative Module UNIX RTR Log Files, Common Network Interface Log Files and 5ESS Log Files. 

 

Lesson 4 – Initialization Analysis:

The Initialization Analysis lesson presents procedures for post recovery analysis of Administrative Module Initializations, Communication Module Initializations, Switching Module Initializations and Common Network Interface Initializations.  Recovery from an initialization is covered in Alcatel-Lucent’s System Recovery (235-105-220) document and CNI Common Channel Signaling (235-200-115) document.  After recovering from an initialization it is very important to identify why the initialization occurred so corrective actions can be performed so the initialization does not reoccur.  This lesson presents this “post” initialization analysis.  The lesson analyzes Initialization Messages, other Printouts associated with the initializations, Administrative Module Postmortem printouts, Communication Module Event History (Postmortem) printouts (and dumps), Switching Module Event History (Postmortem) printouts (and dumps) and Common Network Interface Log Files.  The lesson includes references to Alcatel-Lucent’s Dyna Text 5ESS Switch support documentation and relates procedures in the lesson to the documentation.


 

Lesson 5 – TMS Post Mortem and Asynchronous Failure Analysis:

This TMS Post Mortem and Asynchronous Failure lesson presents procedures to analyze TMS failure printouts and identify the circuitry involved with the failure.  The lesson provides a detailed description and handouts of the CM2 Office Network and Timing Complex (ONTC) and TMS terminations. It then relates the different TMS printouts, reports and dumps to their physical components.  The lesson also identifies how to determine the direction (CM or SM) the TMS error was received from.  The lesson includes register breakdown examples, charts and references to Alcatel-Lucent’s Dyna Text 5ESS Switch support documentation. 

 

 

Lesson 6 – MMRSM, RSM, ORM and EXM Stand Alone Analysis:

This MMRSM, RSM, ORM and EXM–2000 Stand Alone Analysis lesson presents procedures for the post analysis of a Multi Module Remote Switching Module (MMRSM), Remote Switching Module (RSM), Optically Integrated Remote Module (ORM) and Extended Switch Module – 2000 (EXM–2000) Stand Alone occurrence.  Recovery from a Stand Alone is covered in Alcatel-Lucent’s System Recovery (235-105-250) document.  After recovering from a Stand Alone it is very important to identify why the Stand Alone occurred so corrective actions can be performed to ensure the Stand Alone does not reoccur.  The Recovery from a Stand Alone usually identifies and cares for the cause of the outage.  The next important item is to identify the time frames of the Stand Alone and its service impact.  This lesson presents procedures to identify when the Stand Alone occurred, the impact to service caused by the Stand Alone and when the Stand Alone cleared.  These items are usually required for regulatory notifications of the service outage.  The lesson includes references to Alcatel-Lucent’s Dyna Text 5ESS Switch support documentation and relates procedures in the lesson to the documentation.

 

 

Lesson 7 – Single Process Purge (SPP) and Return to Point of Interrupt (RPI) Analysis:

This lesson, Single Process Purge (SPP) and Return to Point of Interrupt (RPI) Analysis, presents procedures to analyze SPP and RPI events and messages.  The lesson begins by defining what an SPP and RPI is and the type of failures they identify.  The lesson then addresses analyzation procedures for Dual Link Interface (DLI) and Network Link Interface (NLI) failures, Data Interface (DI PIDB PARITY) failures, Control Interface (CI) failures and Memory (CORR BIT, MEM-SYSTEM and PARITY ERROR) failures.  This includes the analysis of other related and supplemental messages created by the failure.  The effect to customer service is also discussed with each problem.  This lesson includes references to Lucent’s Dyna Text 5ESS Switch support documentation and relates procedures in the lesson to the documentation. 

 

Lesson 8 – Audit Analysis:
