End user ADSL over POTS

Descriptions

ADSL splitter is an analog low-pass filter installed between analog devices (such as telephones or analog modems) and a plain old telephone service (POTS) telephone line, in order to prevent interference between such devices and a asymmetrical digital subscriber line (ADSL) service operating on the same line. Without ADSL splitter, signals or echoes from analog devices at the top of their frequency range can result in reduced performance and connection problems with ADSL service, while those from the ADSL service at the bottom of its range can result in line noise and other issues for analog devices.
