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. Provides 1 ~ 16 E1 interface, the main optical fiber interface and backup fiber interface, 8*physical isolation 10/100M Fast Ethernet interface (independent 8* wire speed 100M), and 2 extended business interface. 2*extended service interface can be used as RS232/RS485/RS422 asynchronous data/TTL signal, the application is very flexible. Optional digital business phone, optional Console serial network management, optional independent SNMP network management.
Functional Properties
◆  Based on independent intellectual property rights of integrated circuits;
◆  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;
◆  8 physical isolation Ethernet interface rate of 10/100M, full duplex/half duplex adaptive, each wire speed independent bandwidth 100M, the total bandwidth of two-way 8*100M;
◆  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);
◆  Provide 2 expansion interface, optional expansion 1~2 asynchronous data, such as RS232/485/422/TTL; or 1 to 4 dry contact and so on;
◆  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 100 km;
◆  A variety of power supply options: AC220V, DC-48V / DC24V, etc .; support AC + DC; AC + AC; DC + DC dual power backup mode;
