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.

To install a filter for the printer:

1Connect the line port of the DSL filter to the wall jack.

2Connect one end of the telephone cable that came with your printer to the port of the printer. Connect the other end 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.

4To connect a telephone to the printer, remove any installed adapter plug from the port of the printer, and then connect the telephone to the port.
