Digital subscriber lines operate over existing telephone lines to carry what types of content?

Digital subscriber lines (DSL) are a form of high-speed internet connection that utilize existing telephone lines to transmit various types of content. The technology is designed to facilitate simultaneous transmission of voice, data, and video over the same lines without disrupting the standard telephone service.

The primary function of DSL is to provide internet access, which inherently involves data transmission. However, it also supports voice calls—allowing users to make phone calls while simultaneously using the internet. Additionally, DSL can handle video content, making it suitable for various applications such as video conferencing, streaming services, and other multimedia activities.

This capability to carry multiple types of content seamlessly is what distinguishes DSL technology, enabling users to leverage their existing telephone lines to access a comprehensive range of communication and entertainment services.
