Case I: Shared voice/fax line with answering machine
If you receive both voice calls and fax calls at the same phone number, and you also
have an answering machine that answers voice calls at this phone number, set up the
device as described in this section.
Figure 8-9 Back view of the device
1 Telephone wall jack
2 Use the phone cord provided to connect to the 1-LINE port on the back of
the device
3 Answering machine
4 Telephone (optional)
To set up the device with a shared voice/fax line with answering machine
1. Remove the white plug from the port labeled 2-EXT on the back of the device.
2. Unplug your answering machine from the telephone wall jack, and connect it to the
port labeled 2-EXT on the back of the device.
NOTE: If you do not connect your answering machine directly to the device,
fax tones from a sending fax machine might be recorded on your answering
machine, and you probably will not be able to receive faxes with the device.
3. Using the phone cord supplied in the box with the device, connect one end to your
telephone wall jack, then connect the other end to the port labeled 1-LINE on the
back of the device.
NOTE: If you do not use the supplied cord to connect from the telephone wall
jack to the device, you might not be able to fax successfully. This special
phone cord is different from the phone cords you might already have in your
home or office.
4. (Optional) If your answering machine does not have a built-in phone, for
convenience you might want to connect a phone to the back of your answering
machine at the "OUT" port.
NOTE: If your answering machine does not let you connect an external
phone, you can purchase and use a parallel splitter (also known as a coupler)
to connect both the answering machine and telephone to the device. You can
use standard phone cords for these connections.
5. Turn on the Auto Answer setting.
