Fix Recommendation

Suspended carriers may only 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).
Ensure that:

1. Suspended carriers between buildings are permissible if they terminate in a CAA on each end or immediately enter a hardened PDS at the building boundary.

2. The suspended carrier must be hung directly between buildings.

3. The suspended carrier must be elevated a minimum of 5 meters (16 feet 4 inches) and

4. The suspended carrier must only be used if the property traversed is owned or leased by the USG or by a USG contractor or vendor that controls the PDS.

5. Suspended carriers must be installed to provide unimpeded inspection and be clear of any obstruction or device which encroaches upon the system to facilitate tampering.

6. The area containing the suspended carrier must be illuminated at night.

7. The PDS must not be located within an Uncontrolled Access Area (UAA).

Check Contents

Suspended carriers (Exterior PDS) 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).

Check to ensure:

1. Suspended carriers between buildings terminate in a Secret or higher Controlled Access Area (CAA) on each end OR immediately enter a hardened PDS at the building boundary. (CAT I)

2. Suspended carriers are hung directly between buildings. (CAT I)

3. Suspended carriers are elevated a minimum of 5 meters (16 feet 4 inches). (CAT I)

4. Suspended carriers are on property owned or leased by the USG or by a USG contractor or vendor that controls the PDS. (CAT I)

5. Suspended carriers are installed to provide unimpeded visual inspection and be clear of any obstruction or device which encroaches upon the system to facilitate tampering. (CAT I)

6. The areas containing suspended carriers are illuminated at night. (CAT I)

7. The PDS is not located within an Uncontrolled Access Area (UAA). (CAT I)

Potential Impact

There are five types of Category 2 PDS: 1. Hardened Carrier (STIG ID: CS-04.01.02) 2. Alarmed Carrier (STIG ID: CS-04.01.08) 3. Continuously viewed Carrier. (STIG ID: CS-04.01.06) 4. Buried Carrier (STIG ID: CS-04.01.04) and 5. Suspended Carrier (STIG ID: CS-04.01.05).

This Rule covering (External) Suspended Carriers (STIG ID: CS-04.01.05) may be used in conjunction with the other Category 2 carriers. Different requirements apply to each type of Category 2 carrier and must be assessed under their respective STIG Rules.
