For an SDSL broadband Internet connection, the SDSL modem
is situated in the customer's premises, and is used to
encode signals sent over the SDSL channel to the ISP
and decode signals received from the ISP. The SDSL modem provides the same data rates on the uplink and
downlink.
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.
