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.
