Description
Requirement: The IAO will ensure that the power cabling serving SS7 equipment is diversely routed to separate and redundant PDFs. The power cabling of the SS7 equipment needs to be routed diversely and terminate in separate PDF. All power cabling should be clearly marked near the termination of the cabling and near the fuse assignments. These precautions will limit possible service degradations to the SS7 network by making service personnel aware of their location and ensure that the switching facility is not isolated from the DSN network.

Check Text ( C-7329r1_chk )
Perform a walk through of the facility and confirm compliance via inspection of the effected devices or items

Fix Text (F-7523r1_fix)
Label the termination points and fuse positions of power cabling that provides power to signaling equipment. A and B feed power cabling should be routed separately between the signaling frame and the power distribution frame. Power cabling paths that are not diversely routed should be documented and escalated to the ISSO/IAO for resolution.
