Scenario 2: Digital Subscriber Line (DSL)
A Digital Subscriber Line splits your regular telephone line into two channels: voice and Internet. Telephone
and fax signals travel through the voice channel, and Internet signals pass through the other channel. This way,
you can use the same line for analog voice calls (including faxes) and digital Internet access.
To minimize interference between the two channels and ensure a quality connection, you need to install a DSL
filter for the analog devices (fax machine, telephone, answering machine) in your network. Interference causes
noise and static on the telephone, failed and poor quality faxes for the printer, and slow Internet connection on
your computer.
Note: Contact your DSL provider to obtain a DSL filter.
