In a VDSL broadband Internet connection, the VDSL modem
is situated in the customer's premises, and is used to
encode signals sent over the VDSL channel to the ISP
and decode signals received from the ISP. The VDSL modem may provides different data rates on the uplink and
downlink; usually a higher speed is provided on the 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.
