MSDTU01-A/E1 SDSL G.703 E1 CSU
3Version 1.1
Overview
TheMSDTU01-A/E1 SDSL with G.703 Fractional E1 interface is a
data access Channel Service Unit modem with the latest multi-rate
HDSL (High-speed Digital Subscriber Line) technology offering both
long range and high speed data transmission with Nx64 rates from
128Kbps up to 2048Kbps. The transmitting data rate may be adapted
for the best "rate vs. range" performance for efficient and stable data
transmission.
TheMSDTU01-A/E1 uses the 2B1Q line code with echo cancellation
to transmit its high data rate over a single twisted pair of telephone
wires 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.
