Ethernet over 4-Port E1 Converter (75Ω+120Ω)

View : 696
Type : Multi E1-Ethernet Bridge
Description :

The device utilizes inverse multiplexing technology to bundle multiple E1 circuits for transmitting 10/100M Ethernet data, achieving bidirectional conversion between 4 E1 and Ethernet.

Overview

The device utilizes inverse multiplexing technology to bundle multiple E1 circuits for transmitting 10/100M Ethernet data, achieving bidirectional conversion between 1-4 E1 channels and Ethernet interfaces, and interconnecting E1 with Ethernet. Ethernet encapsulation adopts GFP encapsulation and supports LCAS and LAPS protocols.

 

This device supports 4 dual-impedance E1 interfaces (75 ohms + 120 ohms) and has a flexible channel configuration. It can automatically detect the number of E1 interfaces and select available ones, while allowing for a certain transmission delay difference between E1 circuits. The line rate of a single E1 interface is 1984Kbit/s, and the total bandwidth of 4 E1 interfaces can reach up to 7936Kbit/s.

 

It has perfect alarm functions, stable and reliable operation, low power consumption, high integration, and small size. It also has a network management module that supports stand-alone SNMP network management. It is suitable for various fields such as LAN interconnection, local-end interconnection, video-on-demand, remote monitoring, and E1 interface plug-in card of switches.

Features

Realize ethernet data transparent transmission in 1-8E1 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 4-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;

It can support 4 channels E1 channel configuration, can automatically detect the number of E1 and select the E1 available.
