The Litespan-2000 Maintenance Troubleshooting course provides extensive information on the design, use, and maintenance of the AlcatelDSC Litespan-2000 and Litespan-2012 (OC-12) Digital Loop Carrier systems.
The course will provide the skills necessary to perform day-to-day maintenance, plus show how to troubleshoot faults. Various types of documentation will be discussed. This course should also greatly assist personnel when working with next-tier technical support.
The course is intended for those who are responsible for the maintenance and troubleshooting of Central Office systems, plus NOC personnel and first responders who respond to alarms. No previous switching background is required, although some familiarity with CO equipment will be beneficial.

The course is designed to run for 5 days in a classroom setting, but length is easily customized to provide a greater understanding of foundational topics, such as SONET, PCM ATM theory, or shortened to review only the most important topics of interest. More complex troubleshooting concepts can be introduced with this course including various installation documents, such as those which show in detail how system devices are interconnected, or debugging logs, etc. Field trips to actual premises are used when available, allowing students an opportunity to see and understand where all the packs and modules of the system are found, and how they are connected.
Instructor-led with a flexible approach that adjusts content most relevant to students. Includes various labs, demonstrations, and exercises to help students focus on and retain the material presented.
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.
