SOHO to Corporate LAN

The Express L768/L1.5 provides the following basic functions:

1.LAN Bridge: Bridging provides a point-to-point connection between two LANs. The bridge learning function scans the source and destination me- dia access control (MAC) addresses of all packets on its local LAN and de- termines which packets should be transmitted over the HDSL link.

Applications include connectivity between single user or small offices to corporate LANs. The Express L768/L1.5 uses the Spanning Tree Algo- rithm (IEEE 802.1d-ISO/IEC10038), which provides a loop-free topology and redundancy.
