LANCOM 3550 Wireless

Chapter 1: Introduction

14

EN

LANCOM devices with more than one WAN interface (e.g. DSL and UMTS/
HSPDA interface) can be implemented flexibly in backup solutions. The
backup event is triggered for example, when the default route is no longer
available via the DSL interface. The device's UMTS/HSPDA interface can take
its place further along in the backup chain should the the backup router also
fail.



Further information to the configuration of backup lines can be found
in the LCOS reference manual.
