Ethernet to 4-Port E1 Converter

View : 2,429
Type : Multi E1-Ethernet Bridge
Description :

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

Overview

The device adopts inverse multiplexing technology to bundle multiple E1 circuits for transmitting 10/100M Ethernet data, achieving bidirectional conversion between 4 E1 channels and Ethernet interfaces, thus enabling the interconnection of E1 channels and Ethernet. The Ethernet encapsulation adopts GFP encapsulation and supports LCAS and LAPS.

 

It supports a flexible configuration of 4 E1 channels, can automatically detect the number of available E1s, and allows for a certain transmission delay between E1 circuits. The line rate of a single E1 circuit is 1984Kbit/s, and the bandwidth of 4 E1 circuits can reach 7936Kbit/s.

Features

The device can achieve transparent transmission of Ethernet data in 1-4 E1 circuits, with a bandwidth of up to 7936 Kbit/s;

The Ethernet interface rate is 10/100M, with full/half duplex fully adaptive, and supports VLAN protocol;

Each Ethernet port supports AUTO-MDIX (adaptive crossover and straight-through cable);

In a 4-channel E1 line, the maximum delay difference between any two channels can reach 220ms. When the delay difference exceeds this limit, a delay difference alarm will be generated, and the service will be interrupted;

E1 interface is compliant with ITU-T G.703, G.704, and G.823, and does not support the use of signaling time slots;

The device supports optional local timing and tracking E1 line timing modes, and the E1 line timing source can be automatically switched based on signal quality. For example, the E1 line timing source of the system is the first E1;

The device complies with ITU-T standard protocols. The recommended GFP-F encapsulation is G.7041, the recommended VCAT virtual concatenation and LCAS link capacity adjustment method is G.7042, the recommended Ethernet to nxE1 mapping is G.7043, and the recommended Ethernet to single E1 mapping is G.8040;

When the transmission bandwidth is increased, the Ethernet data will not be damaged. When the transmission bandwidth is artificially reduced, the Ethernet data can also be protected from damage through network management;

The E1 branch on both ends can be connected without corresponding to the sequence number;

If a unidirectional failure occurs in an E1 branch, the other direction can still work;

The device has E1 signal loopback automatic detection and cut-off functions. When a loopback occurs on a certain E1 channel, the system will cut off that channel. After the loopback is removed, the E1 channel will automatically recover;

The device has comprehensive alarm indications and can be configured to display local/remote alarms;

The device supports remote/local E1 line-side loopback function, which facilitates testing of the E1 line;

The device supports local system resetting of the remote system;

The device provides a command for the remote interface loopback function, which facilitates line maintenance;

● The device provides a Console management interface, which facilitates installation and commissioning (optional).
