4-Port Ethernet to 8-Port E1 Converter

View : 704
Type : Multi E1-Ethernet Bridge
Description :

This 8E1-4FE converter is based on FPGA, using reverse direction multiplexing technology to bundle multiple E1 circuits to transmit the Ethernet data of 4 channels 100BASE-TX.

Overview

This 8E1-4FE converter is based on FPGA, using reverse direction multiplexing technology to bundle multiple E1 circuits to transmit the Ethernet data of 4Channel 100BASE-TX. It can realize conversion between 8E1 and 4 port Ethernet. This device can transmit the transceiver signal point to point to Ethernet optical interface to make E1 channels interconnected with Ethernet optical interface. The device supports 8-channel E1 configuration, and can automatically detect the number of E1 and select the E1 available. It allows a certain transmission delay difference between E1 circuits.

Features

Based on self-copyright IC;
Realize ethernet data transparent transmission in 1-8 E1 circuits;
It 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, 4-channel Bandwidth is up to 7936Kbit/s;
Support all sets of Ethernet Work Mode
CRC automatic alarm threshold can be set to isolate the poor quality transmission lines and cut off a single direction. When the 2M branch circuit one direction error rate exceeds the 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 8-Channel E1 transmission time delay difference 100ms. When the margin exceeds the allowed range, the system can automatically stop on the E1 that time delay is too large to send data;
E1 interface conforms 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 channel and will not interrupt data transmission;
Can support 8-channel E1 configuration, it can automatically detect the number of E1 and select the E1 available.
