As OEM-support options dwindle, it has become more important than ever for telco personnel to resolve network faults on their own, including the most difficult ones. BTS recognizes the challenges of finding affordable, support-level training, and has worked hard to provide you with no-compromise, expert-led courses at the support level.

The Nokia (formerly AG Communication Systems) GTD-5 Support Course provides a detailed support-level course with updated, full-color block diagrams and images. This course was designed to bring students with a general, maintenance-level competency of the GTD-5 to a considerably more advanced understanding of the system, including its backplane and cabling. This will help the understanding of inter-module connections, so that almost any fault can be traced and corrected. The microprocessor (MP) front-end and Common Memory Units (CMU) are looked at in detail, with an emphasis on the APC and its connections to the ACDC. Important interfaces like the Operations Gateway (OG), LCDT, RCDT, and AMA equipment are explained and accessed, as available. The role and variations of MDC CPX are also discussed.

The course then looks the PCM network, and studies how the SIC, SSW, and BUNW are interconnected. Superordinate and Subordinate status are explained, and how they relate to the BUNW, TSW, and PCUs. Various failing diagnostic examples from previous BUNWTSW faults are reviewed and decoded, including recovery messages such as SMA syndromes and diagnostic fault printouts. In particular, the 1.019 Non-Maskable Interrupt, 3.059 PCM Trace, and 3.028 Executive Reset SMA Syndromes are studied, along with the typical craftsperson action for each.

Documentation such as the UG, CRL and EL are used to trace cabling, and look at the layout of the backplane of key frames. Troubleshooting techniques are taught pro-actively, including Maintenance-window procedures. Time is allotted to work on troubles which students have encountered and want to discuss. Almost any type of hardware or software fault can be reviewed, with an explanation of the typical steps needed for resolution.

Technical staff such as those in the NOCSCC, Central Office Technicians, and certain management personnel, or any others involved with troubleshooting of the GTD-5 switch.

Students should have previously taken the GTD-5 Maintenance And Troubleshooting course, or have a good working knowledge of the modules and operation of the GTD-5 and its IO commands.

The course length is flexible at 5-10 days, with the longer version intended for NOC and key COT personnel who work more frequently on difficult problems. A shorter version is helpful for persons working with either the NOC or TAC, while still allowing them to understand and handle many problems independently.

Instructor-Led with numerous labs and exercises.

This course requires access to customer 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.
