A POTS splitter uses a low pass filter to separate the low end
frequencies of the telephone audio spectrum from the higher
frequencies of the xDSL signals. The splitter should be a passive
device, not requiring power so that "life-line,” voice service can be
provided as has been in the past. This splitter allows for the
traditional voice service that consumers are accustomed to. A splitter
is required at both the customer premises and at the far end (CO).
xDSL that does not use a POTS splitter on customer premises is termed
"splitter-less xDSL". However, there really is no such thing as
splitter-less xDSL. The splitter function in these cases is just
performed at the provider, generally the CO. Whether a POTS
splitter is required or not depends on the xDSL service being
provided.
