However, this allows you to mount different devices like a phone and fax machine at the same time without experiencing slow internet speeds. You can also use a phone to make or receive calls while connected to the internet.
The DSL filter separates the call and data signals sent through the phone line. The signal fewer than 4 kHz are considered voice signals, while signals above 4 kHz are for data; the filter ensures the signals don't cross. Additionally, you can use this DSL filter on various devices, including:
