Hands-On T1 - T3 & T1 Spanline Combo

Course Description

This extensive Hands-On training course combines two of our courses into one 3-day course. This course will be tailored into a 3-day format and will not completely cover the entire 4-days of materials, but will be customized to meet your specific requirements, in the time allotted. The course outlines for each course will have to be looked and marked for the level of importance from high to low, and submitted to BTS for customization.

T1T3
A vast majority of Telecommunications companies use T1 (DS1) and T3 (DS3) systems as the primary method of transporting voice and data on their transmission networks 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 course is an intense training experience that combines T1 and T3 operation with troubleshooting. For this course, BTS provides a live working classroom lab with typical 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.

T1 Spanlines HDSL
This course will also combine 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.
