Wholesale: Products & Services


Course Description

This self-directed, web-based course provides you with knowledge of the CenturyLink™ DS3 product. You will learn how DS3 works and the options available.

CenturyLink DS3 Service is a high capacity service that can be used as a pipeline for voice, data, and video communications, thus eliminating the need for customers to maintain and pay for multiple dedicated lines for different applications. DS3 works by combining multiple DS1 circuits onto a single physical link or data stream.

For information about creating and submitting a service request, please review the Wholesale ASR Private Line training.
