This Virtual Live Instructor-Led GTD-5 course is an extensive and accelerated maintenance course with updated, full-color block diagrams and frame images. The course was designed to jump-start students with little or no switching knowledge to a competency where they can perform Level-1 card-level repair on virtually any of the main modules in the GTD-5 switching system, including the ACDC, the APCTPC complexes, the TCU (expanded non-expanded versions), the MDC, NCU, and SSW, plus all subordinate devices within the BUNW such as the ACU, ALU BLU lines, plus ATU, DCU and EDCU trunks. Ancillary equipment such as SS7 links, recorder announcers, ringing generators, and gateways such as those used for system remote-access equipment, the CPX, Extension Complex, billing, and remote switch monitoring are also discussed as needed. Troubleshooting techniques are taught pro-actively, including Maintenance-window procedures.
Other modules are discussed per the needs of the class, such as the IOM, CMU, and remotes like the RSU, RLU, and MXU, plus the important role of GR-303 compliant RDT remotes in providing voice switching for customers served by optical or digital line networks. The FTU is emphasized, so that students have an appreciation of this critical module, and how line and trunk diagnostics operate.
The GTD-5 Users Guide is used extensively, allowing students to gain confidence in how the guide is presented, and how information can be found quickly. Other key documents are used as needed, like the Product Line Reference Guide (PLRG), Hardware Matrix Report (HDWM), and Cable Running List (CRL), which help show the parts of the system, and how theyre interconnected. Recent-Change can optionally be added to the course, to show the basics on adding lines, trunks, or interrogating switch settings (CONT PARA, EXAM LTT, etc.) plus an overview of FACTS, such as Digit Translation (PRIN DXLN), and call registers (PRIN PROT, PRIN UNPR).
Non-intrusive exercises are provided to locate various modules and cards within the switch, with a large number of previous faults solutions used to gain practical experience. Existing system faults can also be analyzed, with repair action determined by the class, and the analysis provided to the group responsible for repair, where results can later be compared to the recommended action.
