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:
1 Connect 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.
3 To continue using a computer for Internet access, connect the computer to the DSL HPN port on the DSL filter.
4 To connect a telephone to the printer, remove the protective plug from the port of the printer and then connect
the telephone to the port.
