It can be both but its you cant tell from the outside. In the "early
days" of the FTTC/DSLAM Rollout the German Telekom used to construct the
outdoor_dslam cabinets on top of the old cable distribution cabinets
(modulo the real casing). If my information is correct they stopped
doing so because of cost.

This page has an Image of an outdoor_dslam casing with
the cable distribution part left intact.
You can see the construction process from de-casing the old distribution
cabinet and fitting the new outdoor_dslam casing around.
