4E1 to 3FE+ 1 console management protocol converter

View : 175
Type : E1 to Fiber Etherne
Description :

This series of equipment adopts large-scale FPGA design, adopts reverse multiplexing technology, binds multiple E1 circuits to transmit 3-channel 10 / 100base Ethernet data

Overview

    This series of equipment adopts large-scale FPGA design, adopts reverse multiplexing technology, binds multiple E1 circuits to transmit 3-channel 10 / 100base Ethernet data and 1 channel console network management, and realizes the mutual conversion between 1-4 E1 channels and Ethernet optical interfaces. This equipment can transmit the signal from E1 channel to Ethernet optical interface point-to-point, and realize the interconnection between E1 channel and Ethernet optical interface. Different from general remote bridge, this equipment supports flexible configuration of 1-4 E1 channels, can automatically detect the number of E1 and select available E1, and allows a certain transmission delay difference between E1 circuits.
    This equipment provides 4-channel E1 (75 or 120 Ohm) interface, 3-channel Ethernet interface and 1-way console network management. The whole machine is stable and reliable, with low power consumption, high integration and small volume.

Features

Integrated circuit based on independent intellectual property rights;

Transparent transmission of Ethernet data in 1-4 E1 circuits is realized;

Reset operation of local and remote equipment can be realized;

Ethernet interface 100Base-FX, supporting VLAN protocol;

Built in dynamic Ethernet MAC address list (4096), with local data frame filtering function;

The rate of single E1 line is 1984kbit / s, and the bandwidth of 4-channel E1 can reach 7936kbit / s;

Support any setting of Ethernet working mode;

The CRC alarm threshold can be set to automatically isolate the lines with poor transmission quality, and it is cut off in one direction. When the bit error rate in one direction of 2m branch exceeds the exit limit, only that direction will be cut off, and the other direction will not be affected; that is, the two directions of Ethernet transmission can be asymmetric;

The transmission delay difference of 4-channel E1 is allowed to be 100ms. When the difference exceeds the allowable range, the system can automatically stop sending data on E1 with excessive delay;

The E1 interface conforms to ITU-T G.703, g.704 and g.823, and does not support the use of signaling time slots;

E1 interface module includes built-in clock recovery circuit and HDB3 encoding and decoding circuit;

Provide console management interface for easy installation and opening;

It has the function of viewing and displaying the working status of remote equipment at the local end;

The equipment supports hot swap of E1 channel, and automatically detects the effective E1 channel without interruption of data transmission;

It supports the flexible configuration of 1 to 4-channel E1, automatically detects the number and delay of E1 and selects available E1 during reset;
