SDTU-01 SDSL V.35 DSU
3
Overview
The SDTU-01 SDSL DSU with V.35 interface is a data access DSU
modem with the latest multi-rate SDSL (Symmetrical Digital Subscriber
Line) technology offering both long range and high speed data
transmission with rates from 144Kbps up to 2320Kbps. The
transmitting data rate may be adapted for the best "rate vs. range"
performance for efficient and stable data transmission.
The SDTU-01 uses the 2B1Q line code with echo cancellation to
transmit its high data rate over a single twisted pair of telephone wire
without being affected by bridge taps or mixed cable links. It also
provides high immunity to background noise and enables transmission
over multiple pair cables.
