An accelerated version of the traditional Nokia (formerly AG Communication Systems) GTD-5 maintenance and troubleshooting course with updated, full-color block diagrams and frame images.

This 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. Ancillary equipment such as SS7 links, recorder announcers, ringing generators, and gateways such as for 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 procedure.

Envisioned as a minimum 5 day track, the actual course length and content is flexible, and can be adjusted depending upon the needs of the class. A 10 day version of the course provides the traditional maintenance- level background of all switch modules, and many support-level concepts, equipping students to handle most problems independently, while providing an excellent background for NOC and TAC interaction.

Technical staff such as Central Office Technicians, NOCSCC, certain management personnel, and others responsible for the operation and maintenance of the GTD-5 switch who may require cross-training.

A basic understanding of telecommunications and switching principles is helpful due to the accelerated nature of the course.
