Course Description:
This extensive Virtual Live Instructor-led course provides the skills required to perform support and a high-degree of troubleshooting for the DMS-series of switches. The course begins with a fast review of key system operating principles and terms, including use of the CI and MAPCI terminals, and advances quickly to more complex subjects like core and network options, including the scalable XA-Core processor. The original Junctor Network (JNET) and later Enhanced Network (ENET) options are discussed, based upon the needs of a given class. The Link Peripheral Processor (LPP) is also a focus, explaining this new processor's role as both a front-end device and a peripheral module.
Peripheral Modules (PM) are then discussed in detail, looking at the PCM and control signal paths, including cable connections between different devices on the P- and C-sides. Remotes are also discussed in some detail, including important sub-modules like the HIE, ESA, and RMM. Power and grounding are also reviewed, plus how alarms are wired. Routine exercises are compared in different MAPCI menus, to see how options differ in modules like ENET, CM, and lines, including line power converters. Special formatting cards used for SLC-96 and GR-303 are also shown, including how EOC TMC channels support RDT remotes.
The course then looks at various types of documents, including installation docs which describe backplane and cable connections, and how to locate information needed for troubleshooting. Commonly used menus are augmented with hidden or lesser-used options. Certain types of Operational Measurement and debug tools are highlighted. The course then moves to more challenging troubleshooting scenarios, looking at the process to change common equipment devices that affect many circuits, including system recovery steps, such as non-restart SWACT up to a full reload restart.
Previous troubles are reviewed and used as exercises, but time is also reserved for students to present their own experiences or actual troubles which they may currently be working with, providing broad exposure to many different types of faults in a short time. Our non-intrusive exercises equip the student to conduct support activities, including aspects of cabling and the backplane, which helps them to provide assistance to those with less knowledge of the system.
