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.
