Product Description
  This series of equipment is developed by the company PDH optical fiber transmission for ultra-large scale integrated circuit based on the development of point-to-point optical transmission equipment. Provide 1 ~ 4 E1 interface, 1-4 10/100M Fast Ethernet interface (wire speed 100M). 4*FE Ethernet interface for the exchange port, can support VLAN division. Optional digital business phone.
Functional Properties
◆ Based on independent intellectual property rights of integrated circuits;
◆ Modular wide dynamic photodetector;
◆ E1 interface in line with G.703 recommendations, the use of all-digital clock recovery and smooth phase-locked technology;
◆ Ethernet interface rate of 10M / 100M, full duplex / half duplex adaptive;
◆ 4*FE Ethernet interface for the exchange port, VLAN can also be divided into four channels can be set to logic isolation;
◆ With the Ethernet loopback function (when the optical line occurs when the loop, the Ethernet data will not be loop back, effectively prevent the Ethernet loop may cause the Ethernet network paralyzed);
◆ Uses standard 2 wire telephone (non-telephone handles) set as engineering order-wire hotline(optional);
◆ Can detect when the optical signal is lost when the remote device power down or fiber unreasonable, and through the indicator light alarm;
◆ Have the function of displaying the remote device working status at the local end;
◆ Provide remote E1 interface loopback function to facilitate line maintenance
◆ No relay transmission distance of up to 2 to 120 km;
◆ A variety of power options: AC220V, DC-48V / DC24V;
◆ DC-48V / DC24V power supply with automatic polarity detection, installation without distinction between positive and negative;
