Description

4* E1 to 2* Separated Ethernet Converter

Introduce
Overview

IC-4GL is a kind of high-performance, self-educated long-range Ethernet bridge. With low cost, it is fit for bridge connection or LAN stretcher or subsection. IC-4GL can learn automatically MAC address in the connected LAN and only transmit the target address to the frame of another LAN. Its 10/ 100BaseT interface can run in full duplex Ethernet with topology. With transparently sustaining in WAN lines, alterable speed rate will reach up to 7.936Mbps ( 4 lines E1) . There can be one E1 line ( 1984Kbps) ; two E1 lines ( 3968Kbps) ; three E1 lines ( 5952Kbps) ; four E1 lines ( 7936Kbps) ; Transmitting speed rate of E1 line is 2048kbps ( transparent channels E1, unframed) .
The transmission lines of IC-4GL must be transparent and unframed, which is specially fit for satellites and other wireless broadcast.

Features

With 4 E1 lines to transmit 2 Ethernets data, and the 2 Ethernet can work at the same time when they are in different LAN. For example, the IP of LAN1 is 192.10.10.1, the IP of LAN2 is 128.1.1.1 the two Ethernets 10/ 100Mbps can work at the same time by using IC-4GL.

The maximum permitted transmission delay among the 1st E1 to the 4th E1 is 16ms ( on condition to keep the frame in order) , which can permit the device running stably in every kind of completed networks.

Every E1 line only occupy 64Kbps of channels spending when Ethernet data transmission. The factual available bandwidth of every E1 is 1.984Mbps.

Automatically inspecting the number of the available channels of 4 channels of E1 and automatically distributing bandwidth. It is fit for redundant and bandwidth of E1 line.

Support CRC error code threshold setting of every E1 branch. When error code rate of some branch is over the threshold, the system will automatically turn off and separate the E1 branch.

Turn off the separation function to achieve single-direction separation, which means it only cuts off the branch which is over the error code threshold in E1 lines, while transmission in the other direction is not influenced. It can carry out the dissymmetry of the two direction of Ethernet data transmission to be sure that there has the largest data transmission efficiency.

Satisfies the requirements of G.703, G.704, G.706, G.823 and I.431 of ITU.

Support local system to reset the remote system.

Full set of alarm indication, automatically deal with all kinds of line problems.

Detailed line alarm direction output, automatically deal with all kinds of line problems.
