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 connected to power using the supplied

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 1-12.
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.
