In the context of an HDSL broadband Internet connection, the
HDSL modem is situated in the customer's premises, and
is used to encode signals sent over the HDSL channel
to the ISP and decode signals received from the ISP.
Modem
is a contraction of modulator/demodulator, which transforms a digital bit
stream into an analogue signal (in the modulator), and vice
versa (in the demodulator) so that the digital signal can
be passed over an analogue channel.
