ET100/G64 LAN-WAN Bridge

1.0 Overview

The ET100/G64 Network Bridge is a high performance, remote, self-learning Ethernet bridge. Its

solid design makes it ideal for cost-sensitive bridging applications, or as a LAN extender or segmenter

over G.703 64K Co-directional bit stream type infrastructures.
