Cascaded Links
About the RADWIN Cascaded Links
In Chapter 1, we introduced the IDU-R as device for automatic backup of
leased lines. The IDU-R monitors the status of leased lines, and in the event
of a connection failure automatically switches to the radio link. You may
choose which of the two links is the main link and which is the backup link.
It may be configured in cascaded links for multi-hop. The latter situation
arises where the trunk to be backed up is longer than the range of Win-
Link™ 1000.
Figure L-1below shows a simple cascaded link with two hops.
Figure L-1: Cascaded Link with two hops
The trunk to backed up is shown as Trunk2, from IDU A to IDU B. The first
hop is from ODU A to ODU A’. The second is from ODU B’ to ODU B.
Installing Cascaded Links
For most part, installation of the links follows the standard pattern. In both
the Installation and Configuration Wizards, there is an extra window follow-
ing Services selection:
Note
If ODU A’ and ODU B’ are sited close together, they may require collocation.
