Basic Functions

The Express L128T S/T 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 media access control (MAC) addresses of
all packets on its local LAN and determines which packets
should be transmitted over the ISDN link. Applications include
connectivity between single user or small offices to corporate
LANs. The Express L128T S/T uses the Spanning Tree
Algorithm (IEEE 802.1d-ISO/IEC10038), which provides a loop-
free topology and redundancy.
