2 Wire G.SHDSL Modem hdsl E1 V.35 modem:GSDSL
Description
2.3Mbps,2-Wire,G.SHDSL Modem
Introduce
Features
To use ITU G.shdsl standard 2-wire 2304Kbps GSDSL modem
3.5km-9.7km transmitting distance in special lines with 24AWG(0.5mm) and 26 AWG(0.4mm)
Optional digital interface: V.35 and G.703, Rate support :N*64Kbps(3<=N<=36), 2304Kbps can be reached highest
Need not setup rate of slave modem, It follows the speed rate master modem automatically. So it is carried out to administrate the remote equipments in networks
There are many indicator LEDs on the panel to display work state and line of equipment
High-powered 2B1Qline coding technology is used
Low operating cost, simple manipulation, convenient use, need not any software setting up
The test of analog loopback and digital loopback will be finished by keys of front panel
Independent machine have two power supplying modes: alternating current and direct current-48V
Overview
GSDSL is FPGA-based 2-wire 2304Kbps modem. According with ITU G.SHDSL standard, with best concocting technology and very good frequency spectrum compatibility. It can be used in every high-grade and high-speed telecom operation such as transmitting voice, data and images.
GSDSL has strong supervisory control function. You can learn from the panel the start-up, running and line malfunctioning and so on. When the system is malfunctioning, one can locate the fault expediently with loop back test to administrate networks.
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 need not to work). So you can administrate the remote equipments in networks.
