Framed 4E1-1ETH Converter

Thisinterface converter is based on FPGA, using reverse directionmultiplexing technology to bundle for multiple E1 circuits to transmit theEthernet data of 100BASE-TX. It can realize 1-8E1 channel to convert betweenEthernet optical interface. This device can transmit the transceiver signalpoint to point to Ethernet optical interface to make E1 channels interconnectedwith Ethernet optical interface. Unlike general remote network bridge, thisdevice can support 1-8Channel E1 channel configuration, can automaticallydetect the number of E1 and select the E1 available. It allows E1 linestransmission time delay difference.

Feature:

◇  Based on self -copyright IC

◇  To achieve Ethernet data transparenttransmission in 1-8E1 circuits

◇  Can realize the local and the remote devicereset

◇  Ethernet Interface is 100BASE-FX, supportVLAN protocol

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

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

◇  Support all set of Ethernet Work Mode

◇  CRC automatic alarm threshold can be set toisolate the poor quality transmission lines and cut off a single-direction.When 2M branch circuit one direction error rate exceeds threshold, cutting off thisdirection the other direction is not affected; that is to say, both of theEthernet direction transmission can be asymmetric

◇  Allow 8Channel E1 transmission time delaydifference 100ms. When the margin exceed the allowed range, the system canautomatically stop on the E1 that time delay is too large to send data

◇  E1 interface conform to ITU-T G.703, G.704and G.823, not support the use of signal time slot

◇  E1 interface module with inter-set clockrecovery circuit and HDB3 code circuit

◇  Support E1 channel hot-plug in the device,and automatically detects the effective E1 channel and will not interrupt datatransmission

◇  Can support 1-8Channel E1 channelconfiguration, can automatically detect the number of E1 and select the E1available

Parameter
