E1 G.SHDSL Modem E1 over 2-Wire modem

 

Description

GSDSL G.SHDSL Modem is FPGA-based 2-wire 2304Kbps modem. According with ITU G.SHDSL standard, with best concocting technology and very good frequency spectrum compatibility, It has 3.5km-9.7km 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 (N=1~32) of interface of V.35 and E1(G.703). GSDSL 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 dial 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 dosen’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

GSDSL are used in couple. One is set up into Master Mode which is always placed at Telecommunication office. The other is set up into Slave Mode which is always put in the terminal of user
