Using POTS Splitters and Microfilters with an ADSL-over-POTS
WIC (WIC-1ADSL)
POTS splitters and microfilters apply to the ADSL-over-POTS WIC only. They are used on telephone
lines to ensure voice- and data-call quality. POTS splitters result in the best data and voice performance
when the router and the telephone are used on the same telephone line.
POTS Splitters
A POTS splitter (also called a
splitter
) is installed on a telephone line that is connected to both data
(high-frequency) and voice (low-frequency) devices. The splitter routes the high-frequency and
low-frequency signals on the telephone line to the correct device. Signals intended for the router can
disrupt voice calls; signals intended for voice calls can affect router operation.
Most splitters must be installed by the telephone company; however, some splitters can be installed by
the customer. If you are not sure what type of splitter to use, contact your service provider.
