Note:

Ordinary circuit-switched telephone service can be supported on the same copper pair as ADSL by using

micro ﬁlters or Plain Old Telephone Service (POTS) splitter connected between the line and phones, fax machines,

or modems, to provide ﬁltering of the high-frequency ADSL signal to avoid interference between the voice and the

ADSL service.
