The SS7 termination blocks are not clearly identified at the MDF.

V-7947	DSN09.02	SV-8433r1_rule	ECSC-1	unknown

Description
Requirement: The IAO will ensure that the SS7 termination blocks are clearly identified at the MDF. The A links that connect an SSP to the STPs need to be clearly identified and routed diversely throughout the switching facility. The A links will take separate routes from termination point to termination point. The termination blocks of the A links should be clearly identified at the MDF. The routes should not cross each other. If the routes need to cross each other, they should cross at 90-degree angles. 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.
