Interface converter Introduction: Ne2701bridge (also called 2mbps g.703 / ethernet interface converter) serves as a type of data communication equipment to transparently and directly convert the transmit data from 2m g.703 interface into ethernet. It is ideal for the case where low-cost bridging is required. It also can be used as a lan extension. When used as extension or segment switch, it has two working status, namely filtering and non-filtering, to determine whether all communication traffic is allowed to transport to wan circuit or not. Main features: (1 e1interface (1 utp interface, for connection to network card or hub (optional clock: internal clock (master mode); receiving and recovering clock (complete alert and status display 210mm140mm38mm

Pdh optical terminal Function: 8e1(100m ethernet interface is optional) pdh is the multi-service fiber receiving system with the core of fpga, which adopts special patent technique of reducing jitterf=digital phase locked and clock extracted techniquef=2m interface preventing interference technique, etc. It is suitable for the situations of high request reliability and assistant function, such as the specialized networks of mobile, unicom, electric power, army, police, highway and aviation. 8e1+100m pdh can provide multi-interface of e1 and voice. The hardware adopts large scale fpga, collecting code, decoding, message insertion and alarm, and make the circuit simple so as to improve the reliability of the equipment. 438mm*150mm*44mm
