      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. It provides 1 ~ 4 E1 interface 1*10/100/1000M Gigabit Ethernet interface (wire speed 1000M) and 2 extended service interface. Optional digital business phone
      Functional Properties
      ◆  based on independent intellectual property rights of the integrated circuit to achieve four E1 and 1* Gigabit Ethernet data (wire speed 1000M) hybrid transmission;
      ◆  E1 interface in line with G.703 recommendations the use of all-digital clock recovery and smooth phase-locked technology;
      ◆  Equipment to provide the main optical interface and backup fiber interface dual optical port backup function to ensure that business never interrupted;
      ◆  Fiber bandwidth up to 1.5G Ethernet bandwidth wire speed 1000M interface rate of 10/100/1000M full duplex/half duplex adaptive;
      ◆  Support the maximum ultra-10K giant frame Ethernet packet transmission can support the IEEE802.1Q protocol with the use of the switch products;
      ◆  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 optical alarm;
      ◆  It has the functions of displaying the remote state of the remote device at the local end. It provides the functions of the local E1 loopback and the remote E1 loopback to facilitate the line maintenance.
      ◆  No relay transmission distance of up to 2 to 100 km;
      ◆  A variety of power supply options: AC220V DC-48V / DC24V etc .; 
      ◆  DC-48V / DC24V power supply with automatic polarity detection installation without distinction between positive and negative;
