IDU-R
A compact, half 19 inch, 1U plastic unit for 1 x T1/E1 backup, providing
in addition 2 Ethernet ports and an external alarms interface. IDU-R is
an indoor unit used for automatic backup of leased lines. IDU-R
monitors the status of leased lines, and in the event of a connection
failure automatically switches to the radio link. The user configures
which of the two links is the main link and which is the backup link.
IDU-R operates with all WinLink™ 1000 outdoor units.
