4E1/4ETH converter

 4E1 / 4ETH protocol converter uses reverse multiplexing, multi E1 circuits tied up for Ethernet data transmission 10M / 100M, to achieve the mutual conversion 1-4 road E1 channel to Ethernet interfaces between this E1 channel converter can send and receive signals point to point transmission to the RJ45 interface to interconnect E1 channel and Ethernet. And the general remote bridge is different, this converter supports flexible configuration 1-4 road E1 channels can automatically detect the number of E1 and select the available E1, and allows certain transmission delay difference between E1 circuits. Single line rate is 1968Kbit / s, 4-way bandwidth of up 7872Kbit / s. Each Ethernet can be isolated when the device is used in 10 / 100Mbps full / half duplex mode, it can be connected to an Ethernet switch or hub, make full use of the large number of existing telecommunications network resources to extend E1 circuits Ethernet transmission Distance and applications, Ethernet broadband access a good solution. This product can be used in various fields LAN interconnection, interconnection infrastructure, video on demand, remote monitoring, switch E1 interface card and so on.

The protocol converter is a high performance, adaptive remote Ethernet bridge. Its small size, low cost, it is suitable for cost-sensitive bridging applications or as a LAN extender or segmented basis of bitstream structure. Widely used in between WAN and LAN networking, monitoring and other occasions.

□ based on proprietary integrated circuit;
