The Express 4100/4110 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 desti-

nation 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 4100/4110 uses

the Spanning Tree Algorithm (IEEE 802.1d-ISO/IEC10038), which

provides a loop-free topology and redundancy.
