• To achieve Ethernet data transparent transmission in1-4E1circuitsCan realize the local and the remote device resetEthernet Interface is 100BASE-FX, support VLAN protocolInter-set dynamic Ethernet MAC address (4,096) with local data frame filtering functionSingle Channel lines rate is 1984Kbit/s, 4Channel Bandwidth is up to 7936Kbit/s
• 4 Channel10M/100M Ethernet interface can isolate each other to realize communication independently
• Ethernet interface supports10M/100M,half/full duplex auto- adaptable and AUTO-MDIX(crossed line and straightly connected line self-adaptable )
• CRC automatic alarm threshold can be set to isolate the poor quality transmission lines and cut off a single-direction. When 2M branch circuit one direction error rate exceeds threshold, cutting off this direction the other direction is not affected; that is to say, both of the Ethernet direction transmission can be asymmetric
• Allow 4-Channel E1 transmission time delay difference 100ms. When the margin exceed the allowed range, the system can automatically stop on the E1 that time delay is too large to send data
• E1 interface conform to ITU-T G.703, G.704 and G.823, not support the use of signal timeslot
• E1 interface module with inter-set clock recovery circuit and HDB3 code circuit
• Support E1 channel hot-plug in the device, and automatically detects the effective E1 channel and will not interrupt data transmission
• Can support 1-4Channel E1 channel configuration, can automatically detect the number of E1 and select the E1 available;
