Hands-On T1-HDSL Installation & Maintenance for Business Applications Service to: Cell Towers, Routers, PBX/Key Systems and more…

Course Description

A vast majority of Telecommunications companies use T1 copper and HDSL spanlines as the primary method of transporting data to a variety of business customers 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 2-day class is an intense training experience that combines T1 and HDSL spanline operation with hands-on troubleshooting. For this class, 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 using their own T1 test equipment. Troubleshooting includes equipment failures, wiring problems, field repeater problems, cable pair problems and more...
