DSL modem
Step-by-step explanation:
Digital Subscriber Line (DSL) technology is a modem technology that uses existing twisted-pair telephone lines to transport high-bandwidth data, such as multimedia and video, to service subscribers.
Hence, we can also say that a DSL Modem is an FDM (frequency division multiplexing) device that splits the physical circuit into three logical circuits such as phone, upstream data, and downstream data.
