Features:

? Based on proprietary integrated circuits

? Ethernet data transparent transmission through 4E1 circuits

? Ethernet port 100BASE-FX, Support VLAN

? 4E1 circuit the Maximum differential delay up to 220ms between any two E1 circuit. When the delay beyond 220ms,will have poor overrun alarm while the business interruption

? When the transmission bandwidth increases, will not damage the Ethernet data; artificially reduce the transmission bandwidth, can be achieved without damage to the Ethernet data network

? When a single direction E1 tributary fails, the other direction can still work
