Indoor Installation
Installing IDU-E and R units
IDU-E Installation
The IDU-E can be wall mounted, placed on a desktop or take up one half of
a 1U rack slot. The unit should be grounded, cabled to the ODU and con-
nected to power using the supplied AC/DC adapter.

IDU-R Installation
Figure 3-11: IDU-R Rear Panel
Installation of an IDU-R unit differs from other IDU models in one respect:
At the rear of the IDU-R (see
Figure 3-11
) there are two jacks labeled
“Trunks”. For each IDU-R, the E1 cable from outside should be plugged into
one of the trunks, and the E1 cable to the other station should be plugged
into the second trunk, as in the left hand side of
Figure 1-13
.
Apart from the above difference, the link installation including the remaining
part of the IDU installation and connection to the ODU proceeds as
described as above.
