The CSU may either be rack mounted or mounted as a standalone unit. It
can be equipped with several different plug in units, the Signal Monitor Unit,
T1 Office Repeater, and a Fault Location Filter.
Install the Plug In Units
Refer to the documentation provided with the CSU for the information for
setting the options and installing the plug in units.

The CSU may either be rackmounted or mounted as a standalone unit. If the
CSU is to be rack mounted, insert the unit and attach it to the cabinet
uprights using four screws.
If the unit is a standalone unit, place it in the
designated location. The CSU should be mounted as close to the network
interface as possible.
