Hands-On
GTD-5 Live Virtual Maintenance and Troubleshooting
 
Course Description
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.
Students Will Learn
Target Audience
Technical staff such as Central Office Technicians, combo techs, and those who are responsible for the maintenance and troubleshooting of Central Office systems, plus NOCSCC personnel who must respond to alarms. No previous switching background is required, although some familiarity with CO equipment will be beneficial. Certain management and provisioning personnel will also benefit, providing a greater understanding of the resources needed for the system, and how to program it.
Prerequisites
A basic understanding of telecommunications and switching principles is helpful due to the accelerated nature of the course. Our BTS Telephony For Telecom Techs, or our TDM Switching Fundamentals courses are available for students with little or no previous telecom background.

Notes
This course can also be delivered in 5-8-10 day formats, depending upon the number of labs and specific topics covered. This course can also integrate support level topics to prepare students to work at a Tier-2 level, andor add Recent-Change topics to prepare students for programming line and trunk translations.

The course is designed to run in a Live Instructor-Led Virtual Classroom setting, where additional length is added upon request to provide a greater understanding of foundational topics, such as telecom networkstored-program control background, PCM theory, hexadecimal-binary-decimal conversion, and the tracing functions available in the FACTS utility. More complex troubleshooting concepts can also be introduced with this course including various OG logs, inter-bay cabling, and backplane fault analysis (i.e. to help provide a tier-2 expert level of support) for students who need additional skills. Virtual Field Trips can be added to allow students an opportunity to see and understand where all the parts of the system are found, what they do, and to provide a better end-to-end understanding of the switch.

This course can be combined with other courses like the CO Technician Bootcamp, the GTD-5 Support Course, and the GTD-5 Translations Course for a customized curriculum.
Delivery Method
LIVE Virtual Instructor-Led with a flexible approach that adjusts content most relevant to students. Includes various non-intrusive labs, demonstrations, and exercises to help students focus on and retain the material presented.
Equipment Requirements
(This apply's to our hands-on courses only)
This course requires remote access to customer(s) GTD-5 Switch or Switches for Non-Intrusive training.

BTS always provides equipment to have a very successful Hands-On course. BTS also encourages all attendees to bring their own equipment to the course. This will provide attendees the opportunity to incorporate their own gear into the labs and gain valuable training using their specific equipment.

Course Length
