Overview:

 

MSDSL-T4plus is FPGA-based 2-wire 2304Kbps modem. In accordance with ITU G.SHDSL standard, with best concocting technology and very good frequency spectrum compatibility, It has 3.29km and 2.51km transmission distance in special lines with 24AWG(0.5mm) and 26 AWG(0.4mm). It can be used in every high quality and high-speed telecom operation such as transmitting voice, data and images. It also supports N * 64Kbps rate of LAN (comply with IEE802.3u/Ethernet). MSDSL-T4PLUS has strong supervisory control function. You can learn the start-up, running and line malfunctioning and other functions from the panel. In case there is something wrong with the system, one can locate the fault conveniently with loop back test to administrate networks.

Not only with low operating cost, but it is also easy to operate, install and link. One can use the DIP switch on the back panel to setup work mode and transmission rate while slave modem can automatically follow master modem rate (that is the rate switch of the slave doesn’t work). So you can administrate the remote equipments in networks. There are many indicator LEDs on the panel to display work status and line of equipment.
