Protected Distribution System (PDS) Construction - External Suspended PDS
Description
Discussion Text
Suspended carriers (Exterior PDS) are a Category 2 PDS option used to extend a PDS between Controlled Access Areas (CAAs) that are located in different buildings. Suspended carriers may be used for short runs when it is not practical to bury the PDS between buildings (e.g., between the 3rd floors of adjacent buildings). Unlike other Category 2 PDS the unencrypted data cables are not required to be installed in a carrier. Proper elevation and ease of visibility as well as minimum daily visual inspections of suspended carriers is of paramount importance. A PDS that is not configured, physically secured and inspected as required could result in the undetected interception of classified information. This is especially true for unencrypted cables running through an outdoor environment where physical barriers protecting the environment are often easily breeched.
