FDSL3 E1/T1
FDSL-E1/T1(Fractional digital subscriber line) is a device which transmits data of E1- or T1- class of DSI (E) to remote subscribers who need the data to a distance of up to 5km without separate relay devices using lines (0.5mm) of the existing phone subscribers. It can transmit FDSL-E1 (2.048Mbps), FDSL-T1(1.544Mbps)-class data using a CAP modulation system, enables long-distance transmission which can’t be done with the existing CSUs and can make PRI (E1) long-distance transmission of switchboards.
