Encryption / LAN WAN Encryption Unit
Overview

LAN WAN Encryption Unit (LWEU) is transparent equipment which can seamlessly bridge Time Domain and Packet Networks. Data traversing through LWEU can be processed for Encryption, Compression, FEC and/or any Custom Data Processing Technique.

Working

LWEU acts like a bridge between LAN and WAN side interfaces. LAN side interface is 10/100/1000Mbps Ethernet whereas WAN side its E1 or E3 or V.35 or 10/100/1000Mbps Ethernet. In addition LWEU performs Compression/Decompression and Forward Error Correction on the data to be transmitted as well on the data received. Compression is performed to improve the efficiency of bandwidth usage; whereas FEC is performed when retransmission is either not advisable or not possible.
