Hands-On T1 Spanline, HDSL / HDSL-2 / HDSL-4 Operations, Maintenance & Troubleshooting

Course Description

A vast majority of Telecommunications companies use T1 Copper and HDSL Spanlines
as the primary method of transporting voice and data on their local loop therefore, having
well trained technicians with the ability to install, maintain and troubleshoot these systems
is vital to providing high-quality reliable service to customers in a highly competitive
environment.

This Hands-On 2-day course is an intense training experience that combines T1 Spanline
and HDSL operation with troubleshooting. For this course, BTS provides a live working
classroom lab with typical spanline equipment currently deployed in the telecommunications
industry. Students learn how these systems work then are required to use the knowledge to
test, troubleshoot and repair the circuits. Troubleshooting includes equipment failures, wiring problems, field repeater problems and cable pair problems.

Students Will Learn
