What is sdsl?
I hope the answer must have already been clear. But still, let
me give you a proper conclusion. DSL modem can have two types, SDSL
and ADSL. Though, most of the times when we use the word DSL, we
generally refer to the ADSL modem, but in certain cases, it can
even be the SDSL modem. Hence, this is the difference. An ADSL
modem can send and receive data at different speeds while SDSL
modem can send data at only one speed.
