Step 1:
Install the Line Filter
Devices such as fax machines or phones that share the same phone line as your ADSL account
require a line filter, which protects your phone or fax from ADSL frequencies. Filters can be in
the form of a stand-alone Line Filter or a Y-Line Filter. The Y-Line Filter can be used if your
ADSL modem will share the same phone jack with another device.
Stand-alone Line Filter
For each device that shares the phone line as your ADSL account:
1. Unplug the device's cord from the phone jack.
2. Plug the filter into the phone jack.
3. Plug the phone cord (or other device cord)
into the filter.
Y-Line Filters
If your SIEMENS ADSL C-110 and another device will share the same phone jack, install a
Y-Line Filter:
1. Unplug the device's cord from the phone
jack.
2. Plug the Y-Line Filter into the phone jack.
3. Plug the phone cord (or other device cord)
into the "PHONE" jack of your Y-Line Filter.
4. Plug the ADSL cord into the "ADSL" jack of
your Y-Line Filter.
