Description

2 E1 to Ethernet Converter

Introduce

Features

The maximum permitted transmission delay among the first E1 to the 2 E1 is 32ms ( on condition to keep the frame in order) , which can permit the device running stably in every kind of completed networks.

Two channels of E1 can connect together without gap, which means the package will not be lost while adding or reducing E1 line. Two channels of E1 ensure the hot swap redundant and keep network' s continuous running.

Ethernet 10M/ 100M, full/ half duplex self-adaptive, also can be chose manually. The connection mode can be crossing mode or direct mode depend on self-adaptive.

Every E1 take 64Kbps, every E1' s invalid bandwidth is 1.984Mbps

Automatically inspecting the number of the available channels of 2 channels of E1 and automatically distributing bandwidth. It' s fit for redundant and bandwidth of E1 line.

Support CRC error code limit setting of every E1 branch. When error code rate of some branch is over the limit, 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.

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

Full set of information on network console, including the condition of local terminal, remote terminal and Ethernet interface.

Rich indicator LEDs which can display the working status and alarm signal of equipment.

Overview

IC-2GL 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-2GL 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 3.968Mbps( 2 lines E1) . There can be one E1 line ( 1984Kbps) ; two E1 lines ( 3968Kbps) . Transmitting speed rate of E1 line is 2048kbps ( transparent channels E1, unframed) .

The transmission lines of 2E1-T must be transparent and unframed, which is specially fit for satellites and other wireless broadcast. LAN interface of IC-2GL support 100M full duplex, self-adaptive mode. So the device must be linked with Ethernet Switch or PC ( HUB is invalid) . And it is required that it' s connected port must support self-adapting mode ( full duplex/ half duplex) .
