SDSL system utilizes only one pair
of copper wires but enables symmetric transmission from 272 Kbps
to 2,320 Kbps (40 times faster than 56 Kbps analog modem) at maximum
distance of about 3 km(10,000 ft) supporting megabit transmission,
integrated voice, data and even interactive video communication
at MPEG1 rates as the block diagram shown below.
By adding SDSL POTS Splitter as shown
below, an additional dedicated phone line, not interrupted even
when the power failure, can be provided same as ADSL POTS Service.
Passed interoperability test with
various SDSL systems implemented by Conexant SDSL chip set.
