Scenario 2: Digital Subscriber Line (DSL)
Follow this setup if you have a Digital Subscriber Line (DSL).
EXT
LINE
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 faxing) 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.
To install a filter for the printer:
1Connect the line port of the DSL filter to the wall jack.
2 Connect a telephone cable from the 
port on the back of the printer to the phone port on the DSL filter.
3To continue using a computer for Internet access, connect the computer to the DSL HPN port on the DSL filter.
