DLX-4E1E 10/100M to 4E1 Protocol Converter

Product Introduction

 DLX-4E1E 4E1 to 10/100Base-Tx converter designed to transmit Ethernet data through several E1 channels, DLX-4E1E support point-to-point transmission of Ethernet MAC frame data through one to 4 E1 channels, detect and use the effective E1 channels automatically, apply the reversed multiplexing technology to bind several E1 circuits together to transmit Ethernet data at 10/100Mbps, and allow certain transmission time delay between E1 circuits.

This equipment can make efficient use of a large amount of existing E1 circuit sources in the networking to expand the Ethernet transmission distance and application range. The highest transmission rate of transparent transmission design for the Ethernet data through one to four E1 circuits is 7.68Mbps. So it is a very good solution for the Ethernet broadband access, easy to expand the application scope and transmission distance of Ethernet.

 DLX-4E1E is high integration, strong reliability, low power, small size and complete function. It’s best advantage is the broad transmission channel protected well, enabling stable working in bad situation. There is no adjusting point for the installation of the whole unit, easy to operate and simple to maintain.


Product Feature

    Ethernet interface comply with IEEE 802.3 protocol standard supports 10M/100M full duplex/semi-duplex working modes.

     Capable of transmitting transparently the ultra long frame, and supports the Ethernet switch with VLAN function.

     Built-in dynamic Ethernet MAC address (10,000 addresses) list in the chip and the local data frame filtering function.

     Built-in SDRAM (256K Byte) controller.

     E1 interface comply with ITU-T G.703, G.704 and G.823.

     E1 interface module contains the built-in clock recovery circuit and HDB3 code circuit.

     Supports the availability checking and automatic troubleshooting of 1 to 4 E1 channels.

     Visible and audible alarm indication.

     Real-time error code monitoring and automatic protection of E1 channels.

     E1 line loop back function supported.

     Allows the maximum 8ms time-delay of 4 channels, the system can stop to send data automatically when the time-delay is big.
