8E1 to 4*Ethernet interface converter with logical isolation

•  Based on self -copyright IC
• To achieve Ethernet data transparent transmission in 1-8E1 circuits
•  Can realize the local and the remote device reset
•   Ethernet Interface is 100BASE-FX, support VLAN protocol
•  Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering function
• Single Channel lines rate is 1984Kbit/s, 8Channel Bandwidth is up to 7936Kbit/s
•  Channel 10M/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 onedirection error rate exceeds threshold, cutting off this direction the other direction is not affected; that is to say, both of the  Ethernet directiontransmission can be asymmetric
•   Allow 8-Channel E1 transmission time delay difference 100ms. When the margin exceed the allowed range, the system can automatically stopon 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 1-8Channel E1 channel configuration, can automatically detect the number of E1 and select the E1 available;
