4E1 to 10/100M Ethernet Protocol Converter

Brief 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.
