Information on Symmetric Digital Subscriber Line Modem
For an SDSL broadband Internet connection, the Symmetric Digital Subscriber Line 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.
