Framed 8E1-1ETH Converter

Thisinterface converter is based on FPGA, using reverse direction multiplexingtechnology to bundle for multiple E1 circuits to transmit the Ethernet data of100BASE-TX. It can realize 1-8E1 channel to convert between Ethernet opticalinterface. This device can transmit the transceiver signal point to point toEthernet optical interface to make E1 channels interconnected with Ethernetoptical interface. Unlike general remote network bridge, this device cansupport 1-8Channel E1 channel configuration, can automatically detect thenumber of E1 and select the E1 available. It allows E1 lines transmission timedelay difference.

Feature:

◇ Based on self-copyright IC

◇ To achieve Ethernetdata transparent transmission in 1-8E1 circuits

◇ Can realize the localand the remote device reset

◇ Ethernet Interface is100BASE-FX, support VLAN protocol

◇ Inter-set dynamicEthernet MAC address (4,096) with local data frame filtering function

◇ Single Channel linesrate is 1984Kbit/s, 4Channel Bandwidth is up to 7936Kbit/s

◇ Support all set ofEthernet Work Mode

◇ CRC automatic alarmthreshold can be set to isolate the poor quality transmission lines and cut offa single-direction. When 2M branch circuit one direction error rate exceedsthreshold, cutting off this direction the other direction is not affected; thatis to say, both of the Ethernet direction transmission can be asymmetric

◇ Allow 8Channel E1transmission time delay difference 100ms. When the margin exceed the allowedrange, the system can automatically stop on the E1 that time delay is too largeto send data

◇ E1 interface conformto ITU-T G.703, G.704 and G.823, not support the use of signal timeslot

◇ E1 interface modulewith inter-set clock recovery circuit and HDB3 code circuit

◇ Support E1 channel hot-plugin the device, and automatically detects the effective E1 channel and will notinterrupt data transmission

◇ Can support 1-8ChannelE1 channel configuration, can automatically detect the number of E1 and selectthe E1 available
