Course Description:
This extensive course provides the skills required to perform maintenance and a high-degree of troubleshooting, and will walk the student through a practical understanding of the Ericsson AXE 10 switching system and several module magazine options. It discusses the use of MML maintenance terminals, including the use of serial port, Windows NT2003 based AT terminals, and alarm consoles.
The APZ and APT processor systems are described in detail, along with an overall theory of operation for the switch, and how it aligns with the software block system. System output messages such as the System Recovery Log (SYRIP), Alarm List (ALLIP), recovery logs, and other standard AT messages are reviewed with exercises to practice troubleshooting steps. The DynaText electronic document system is also reviewed, including topics such as operations, maintenance, and troubleshooting books. Previous troubles or actual issues being experienced by the student are reviewed, and used as exercises. Topics may include any common modules from in the Subscriber Step (SS) and TrunkSignal System (TSS), but also the Group Switch, Regional Processors, and the CP front-end. The IOG architecture is also included, with a discussion of how to perform tape and magneto-optical maintenance. Terminal connections are described for critical IO access.
Our non-intrusive exercises equip the student to conduct day to-day maintenance activities, perform troubleshooting procedures, plus understand the cabling and various parts of the backplane, and much more. The course is flexible, allowing the most important content for a particular group of students to be emphasized.
